Gas station feasibility study.
Gas station and convenience store fuel retail is among the most active SBA 7(a) and 504 lending categories in the U.S., with the third-party feasibility study mandatory under SOP 50 10 8. This page sets out what a bankable gas station feasibility study contains, the fuel margin and c-store revenue methodology that anchors it, and how the deliverable is scoped sub-segment by sub-segment.

Gas station and convenience store fuel retail is among the most active SBA 7(a) and 504 lending categories in U.S. small-business commercial real estate finance, with annual SBA-financed transaction volume running consistently in the thousands of loans across new construction, acquisition, and refinance activity. The asset class has structurally evolved over the past two decades from standalone fuel retail to convenience-store-anchored format where fuel volume drives traffic and the c-store revenue line drives operating margin — and the modern fuel-retail format frequently includes a car wash, branded quick-service-restaurant tenant, or other ancillary revenue lines that further transform the operating economics.
The structural reason the feasibility study is mandatory in gas station lending parallels the hotel, self-storage, and car wash pattern. SBA's standard operating procedure (SOP 50 10 8) treats gas stations as special-purpose property, triggering the third-party feasibility requirement on new construction, substantial renovation, and conversion. Conventional bank construction lenders apply the same standard. The asset class's outcomes depend on a compact set of analytical variables — traffic count and access quality, fuel volume and margin, c-store revenue and mix, branded versus unbranded supply economics, and increasingly EV charging integration capital planning — and each variable is measurable, verifiable, and consequential to the loan.
A bankable gas station feasibility study runs across nine analytical components: site characterization with traffic count verification, supply-agreement structure (branded major versus unbranded versus independent jobber), trade-area capture analysis, fuel volume and margin projection, c-store revenue projection by category, ancillary revenue (car wash, QSR tenant, ATM, lottery) where applicable, capital cost build-up tied to the chosen format, comparable property analysis, and stabilized cash flow modeling against the lender's DSCR threshold. This page sets out the methodology each component requires.
Why gas station feasibility is lender-mandatory.
Gas station is one of three asset classes — alongside hotels and self-storage — where SBA SOP 50 10 8 treats the property as special-purpose and triggers the feasibility study requirement on new construction, substantial renovation, and conversion projects. Car wash carries a similar treatment under the same SOP framework. The special-purpose treatment reflects the asset class's structural sensitivity to local trade-area dynamics, traffic patterns, and the underlying environmental and operational complexity that fuel retail carries.
The alternative-use limitation is meaningful in gas station underwriting. A fully developed fuel retail site — with underground storage tanks, fuel dispensers, canopy structure, c-store building, and prepared site infrastructure — cannot easily be repositioned to retail, restaurant, or other commercial use without underground tank closure, environmental remediation where necessary, and material site reinvestment. The collateral economics therefore depend on the operating cash flow of the fuel retail business itself, which makes the feasibility study's projection of that cash flow consequential to the loan.
Conventional bank construction lenders apply the same standard practice. Almost no regional or money-center bank will fund a gas station construction loan without an independent third-party feasibility study, and most banks specify the analyst qualifications, the trade-area methodology, the deliverable scope, and frequently the environmental documentation requirements (tank registration, Phase I ESA scope, potential Phase II ESA triggers) in their commitment letter terms. The institutional standard among CMBS conduit lenders that engage with gas station collateral — typically through net-lease structures with branded operators or through portfolio transactions — is consistent: the feasibility-style market study is the analytical input the underwriter relies on, with deliverable scope scaling with deal complexity.
The mandatory practice has produced a methodological convention in U.S. gas station feasibility that runs across analyst firms with relatively limited variance. Trade-area definition follows traffic-count-anchored conventions, fuel volume modeling runs against published industry benchmarks (NACS State of the Industry data, EIA fuel consumption statistics, Feasibility Study Consultant database), c-store revenue projection runs against NACS category benchmarks, and the operating projection runs against industry-recognized margin and expense conventions. Institutional reviewers — SBA Certified Development Companies, conventional bank credit committees, and specialty fuel-retail acquisition diligence teams — recognize the convention immediately and identify methodological deviations on first review.
The lender matrix for gas station.
Each capital source requires a different scope. The matrix anchors the deliverable scope — the analyst builds to the union of requirements across the channels actually in play on the deal.
| Capital source | Feasibility required | Typical loan size | DSCR threshold | Format fit | Notes |
|---|---|---|---|---|---|
| SBA 7(a) | Mandatory under SOP 50 10 8 | $500K–$5M | 1.20x–1.25x | Branded c-store, unbranded, gas+car-wash | Owner-operator borrower; 25-year amortization on real estate |
| SBA 504 | Mandatory under SOP 50 10 8 | $1M–$5.5M (504 third) | 1.20x–1.25x | C-store-anchored new construction, larger projects | Real estate-heavy projects; 25-year debenture |
| Conventional bank construction | Mandatory at almost all banks | $3M–$20M | 1.25x–1.40x | All formats including truck-stop | Bank or borrower engages, bank approves scope |
| CMBS conduit | Required for portfolio transactions | $5M–$40M+ | 1.30x–1.40x | Net-lease branded portfolios | Single-tenant net-lease structures common |
| Private credit / debt fund | Bridge, value-add, platform-acquisition | $5M–$50M+ | 1.10x–1.30x | Portfolio rollups, repositioning, conversions | Bridge debt sizing analysis |
| Sale-leaseback / net-lease capital | Underwrites operator credit, not asset feasibility | Varies | N/A — operator-credit-driven | Branded major net-lease, institutional operators | Feasibility supports underlying real estate value |
The capital-source layer determines the analytical depth in every other section of the deliverable. An SBA 7(a) study on an owner-operator first-site branded c-store follows a different scope than a CMBS conduit study on a multi-state branded portfolio, even though both are nominally "gas station feasibility studies." The methodology framework is consistent across the spectrum; the analytical depth, the comp set scope, the environmental documentation, and the projection-period horizon scale with the deal complexity.
Branded major vs unbranded independent — the supply-agreement decision.
The single most consequential operational decision in U.S. gas station development is the supply-agreement structure: whether the site operates under a branded major fuel agreement (Shell, BP, Chevron, ExxonMobil, Phillips 66, Marathon, Sunoco), under an unbranded supply arrangement with a wholesale jobber, or as an independent operator without formal supply commitments. The decision drives capital cost, fuel volume, fuel margin, and operating economics simultaneously.
Branded major operations require a long-term supply agreement with the major oil company — typically a 10- to 20-year branded supply contract — that obligates the site to purchase fuel exclusively from the brand at the brand's wholesale pricing, to display the brand's signage and pumps, and to maintain the brand's image standards. In exchange, the site receives the brand's national marketing support, the credit-card network preference (the brand's loyalty programs and co-branded credit cards), and the volume premium that brand recognition produces — typically 15 to 30 percent higher fuel volume per pump than comparable unbranded sites in the same trade area.
The trade-off runs through fuel margin. Branded major supply agreements typically deliver wholesale fuel pricing 4 to 10 cents per gallon above the comparable unbranded rack price, and the branded site cannot capture the wholesale margin advantage that unbranded operators enjoy when the wholesale market moves. Branded retail margins on regular gasoline typically run 12 to 22 cents per gallon at stabilization, versus 18 to 35 cents per gallon at well-positioned unbranded operations. The branded site recovers the margin differential through volume premium and through the c-store revenue lift that branded customer traffic produces.
Unbranded operations purchase fuel from wholesale jobbers at rack pricing without long-term brand commitment, with the operator retaining flexibility to switch suppliers and to capture wholesale-market margin opportunities. Unbranded volume runs lower per pump (typically 80 to 90 percent of comparable branded sites in the same trade area), but the higher wholesale margin frequently produces equivalent or stronger per-gallon profit at the operating-margin level.
Independent and unbranded operations dominate the lower-volume tertiary-market and rural site categories where branded major economics do not pencil, while branded major operations dominate the high-volume suburban and urban-infill categories where the volume premium and c-store traffic advantage justify the supply premium and the brand commitment.
The feasibility's supply-agreement analysis runs the comparison explicitly. The projected fuel volume under each structure, the projected fuel margin under each structure, the c-store revenue impact under each structure, and the resulting per-site stabilized cash flow combine to produce the structure decision documentation that institutional lenders rely on.
Trade area methodology and traffic count modeling.
Trade area definition in gas station feasibility runs primarily from traffic count rather than from concentric-ring demographics. The fuel-retail customer's purchase decision typically runs at the moment of passing the site or at the moment of recognizing a need to refuel, which makes the traffic stream on the adjacent road the structural input rather than the trade-area's residential population.
The standard convention runs through three layered analyses. Adjacent-road traffic count from state DOT annual average daily traffic (AADT) data establishes the structural traffic exposure. Capture rate against the traffic stream — typically 0.5 to 2.5 percent of passing vehicles per day on the adjacent road, depending on competitive density, site visibility, ingress/egress quality, and brand strength — produces the projected daily fuel transaction count. Demographic depth in the immediate trade area (typically 1- to 3-mile rings) supports the c-store revenue projection because c-store customers, unlike fuel-only customers, draw more heavily from the local residential and commuting population.
Traffic count is the foundational variable. Branded major c-store-anchored sites typically require 25,000 to 40,000-plus AADT on the adjacent road for institutional viability, with the higher end concentrated in dense suburban and urban-infill submarkets where competing fuel supply is meaningful. Tertiary-market and rural sites can support viable economics at materially lower AADT (10,000 to 18,000) where the competitive supply is thinner and the per-site capture rate runs higher. Truck-stop and travel-center formats require interstate or major-arterial traffic exposure (typically 30,000 to 60,000-plus AADT with meaningful interstate or commercial-truck traffic share).
Capture rate against the traffic stream is the central analytical conclusion. The methodology runs against industry benchmarks: stabilized branded c-store sites in standard suburban markets typically capture 1.0 to 1.8 percent of adjacent AADT as daily fuel transactions, with the upper end concentrated at sites with dominant traffic-stream visibility, easy access, and strong brand presence. The capture rate translates into projected daily fuel transactions, which combine with average fueling-volume-per-transaction (typically 8 to 12 gallons per fueling event in 2026 light-vehicle markets) to produce projected daily fuel volume.
Ingress and egress quality is the second site variable. Gas stations depend heavily on easy access from the adjacent traffic stream — a fuel customer making a moment-of-decision purchase will not navigate complex turns, traffic signals with long cycle times, or restricted-access patterns. The feasibility documents the site's actual access pattern: curb cuts, signal proximity, median or curb configurations, and any specific access constraints. Sites with restricted or difficult access frequently underperform AADT-based projections by 20 to 40 percent because the access friction suppresses the moment-of-decision purchase pattern.
The deliverable documents the trade area methodology explicitly with state DOT AADT data (with explicit treatment of the count's age — state DOT counts frequently lag actual traffic by 12 to 36 months), site visit observations during representative weekday and weekend traffic windows, capture rate benchmarking against comparable sites in the trade area or in adjacent comparable markets, and explicit comparison against industry capture rate norms for the format and traffic-density tier.
Fuel volume and margin economics.
Fuel volume and margin together drive the structural cash-flow component of gas station economics. The projection runs across two structurally distinct revenue lines (fuel and c-store) that have to be modeled separately because they operate on different volume drivers, different margin economics, and different demand patterns.
Fuel volume in 2026 institutional U.S. gas station operations typically runs 80,000 to 250,000-plus gallons per month at stabilization, with material variation by site characteristics and format. Branded major c-store-anchored sites in standard suburban markets typically project 130,000 to 200,000 gallons per month at maturity. Higher-volume sites in dense urban-infill and high-traffic suburban submarkets reach 220,000 to 350,000-plus gallons per month. Truck-stop and travel-center formats reach materially higher volumes (frequently 400,000 to 800,000-plus gallons per month) driven by commercial-truck diesel demand. Lower-traffic tertiary and rural sites typically project 50,000 to 100,000 gallons per month.
Fuel margin runs as the structural margin variable. Retail fuel margin — the difference between the retail per-gallon pump price and the operator's wholesale acquisition cost — typically runs 12 to 22 cents per gallon at branded operations and 18 to 35 cents per gallon at unbranded operations on regular gasoline. Mid-grade and premium gasoline run materially higher margins (typically 20 to 40 cents per gallon at branded and 30 to 50 cents at unbranded). Diesel margins typically run 18 to 35 cents per gallon depending on demand environment and location.
The fuel margin projection has to acknowledge cyclical volatility. Fuel margins compress during periods of rapidly rising wholesale prices (when retail price increases lag wholesale increases at the pump) and expand during periods of falling wholesale prices (when retail prices fall slower than wholesale). The feasibility documents the trailing-five-year margin pattern at the trade area level where data permits, with explicit treatment of the cyclical pattern and a normalized stabilized margin assumption that institutional reviewers can underwrite to.
Fuel revenue projection translates volume across margin to produce monthly fuel gross profit. A branded c-store site at 160,000 monthly gallons, blended margin of 18 cents per gallon (across regular, mid-grade, premium, and diesel) produces approximately $345,000 in annual fuel gross profit. The fuel gross profit covers the fuel-side operating costs (credit-card processing fees on fuel sales, fuel-pump maintenance, dispenser inspection costs) and contributes the residual to site-level NOI. The c-store gross profit (Section 6) combines with the fuel contribution to produce total stabilized site cash flow.
Convenience store revenue, mix, and margin.
The convenience store revenue line — historically the secondary revenue source in fuel retail — has structurally become the primary margin driver in modern U.S. fuel retail. The c-store gross profit at a stabilized branded c-store-anchored site frequently exceeds the fuel gross profit despite running on materially lower top-line revenue, because c-store margins run 25 to 40 percent versus fuel margins of 8 to 15 percent (margin as percentage of revenue, with fuel calculated against the high pump price).
C-store revenue projection runs across category lines. NACS publishes the standard category framework that institutional analysis follows: tobacco, packaged beverages, foodservice (prepared food, dispensed beverage, hot dispensed), beer, snacks (salty snacks, alternative snacks, candy), packaged ice cream and frozen, lottery, and other categories. Each category carries distinct revenue contribution, margin profile, and demand pattern.
Foodservice has become the structural growth category in modern fuel retail. Hot dispensed beverage (coffee), prepared food (breakfast sandwiches, hot dogs, pizza, made-to-order sandwiches), and dispensed beverage (soft drinks, slush) together typically run 20 to 35 percent of c-store revenue at stabilized institutional sites, with margins running 35 to 55 percent versus tobacco and packaged-beverage margins of 18 to 28 percent. Foodservice is the category where format differences (branded c-store versus unbranded versus quick-service-restaurant tenant integration) produce the largest economic differentials.
Tobacco runs as the historical anchor revenue category, typically representing 25 to 40 percent of c-store revenue but at structural margin pressure as multiple states implement excise tax increases and as consumption patterns continue gradual decline. The feasibility's tobacco projection accounts for the trade area's state and local tobacco tax environment and the demographic age distribution that drives tobacco-product demand.
C-store stabilized revenue typically runs $1.2 million to $3.5 million annually at branded c-store-anchored sites, with material variation by site characteristics and category mix. The C-store gross profit at the typical 30 to 35 percent blended margin frequently runs $400,000 to $1.2 million annually, comparable to or exceeding the fuel gross profit at the same site.
The deliverable documents the c-store revenue projection at the category level, with NACS benchmarks supporting per-category revenue and margin assumptions. Site-specific factors (foodservice program quality, lottery and tobacco availability, beer license status where applicable, local QSR tenant relationships) drive variation against the benchmark and require explicit documentation.
Site selection variables and the modern fuel-retail format.
Beyond the traffic count and access factors documented in Section 4, modern gas station site selection runs against three additional structural variables that institutional reviewers examine.
Site dimensions and dispenser count drive the throughput capacity. Modern branded c-store-anchored fuel retail typically operates 6 to 12 fuel dispensers (each dispenser serving 2 vehicles), producing instantaneous capacity of 12 to 24 simultaneous fueling vehicles. Sites with fewer than 6 dispensers struggle to capture peak-hour traffic in busy submarkets; sites with 12-plus dispensers carry capital cost premium that lower-traffic locations cannot justify. Site dimensions of 1.0 to 2.5 acres typically support modern format requirements (dispenser island count, c-store building footprint, vehicle circulation, parking, signage), with smaller infill sites requiring careful format optimization.
Demographic and commuting depth supports the c-store revenue. Modern fuel retail c-store revenue draws heavily from the immediate residential and commuting population — workday morning and evening commute peaks, weekend leisure traffic, and local-resident weekly shopping patterns — which means demographic depth in the 1- to 3-mile primary trade area materially affects the c-store projection. Median household income above $50,000, household vehicle ownership above 1.5 per household, and population density of 2,000-plus residents per square mile in the primary trade area typically support institutional c-store revenue projections.
Competitive saturation is the third variable. The standard convention identifies all competing fuel retail sites within 1 mile of the subject (typically 4 to 8 competing sites in suburban submarkets, frequently 10-plus in dense urban areas), documents each competitor's brand, format, dispenser count, c-store size, and operating quality observable through site visits. Trade areas with multiple modern branded c-store-anchored competitors at high traffic counts frequently support viable subject economics through differentiation (better access, fresher format, stronger c-store program), while trade areas with one or two dominant competitors at limited additional traffic capacity frequently produce competitive saturation that the subject's feasibility has to acknowledge.
The modern fuel-retail format has converged on c-store-anchored configuration with 4,000 to 6,000 square foot c-store buildings, 8 to 12 fuel dispensers, foodservice program (frequently with branded QSR tenant integration — a Subway, Dunkin', Krispy Krunchy Chicken, or similar regional QSR brand), and increasingly an integrated car wash component. The standalone gas station without c-store is structurally rare in new development — almost all new SBA-financed and conventional-bank-financed projects deliver in the c-store-anchored format — and the feasibility documents the chosen format against the modern industry standard.
EV charging integration and 2026 capital planning.
The 2026 capital planning environment for U.S. gas station development runs against the longer-term electric vehicle adoption trajectory that institutional fuel-retail capital has been planning around for the past five-plus years. The feasibility study addresses the EV transition explicitly because lender underwriting horizons (25-year SBA amortization, 30-year debenture on 504 structures, 10-year takeout cycles on conventional bank construction) extend across periods where EV adoption will materially affect fuel volume.
EV adoption in U.S. light vehicle markets reached approximately 9 to 12 percent of new vehicle sales in 2025-2026, with regional variation running from 25-plus percent in California and West Coast markets to single digits in many Sun Belt and Midwest markets. Light-vehicle fleet turnover at 7 to 10 years means total EV share of registered vehicles lags new sales share by approximately 5 to 7 years, with most institutional analysis projecting EV share of total registered light vehicles reaching 15 to 25 percent by 2030 and 35 to 50 percent by 2035 depending on regional adoption pace. The feasibility's fuel volume projection over the loan term has to acknowledge the projected fuel demand trajectory.
The institutional response runs across two strategic pathways. EV charging integration — installing DC fast-charging stations alongside fuel dispensers — captures the EV customer at the same site that historically captured fuel customers, with the EV charging customer typically carrying higher per-visit c-store spend (longer dwell time during charging supports food service and impulse purchases). DC fast-charging capital cost runs $80,000 to $150,000 per charger plus electrical infrastructure (transformer upgrades, switchgear, conduit and conductor) that frequently runs another $150,000 to $400,000 per site. Federal NEVI (National Electric Vehicle Infrastructure) funding and state-level incentive programs cover meaningful portions of the capital cost on qualifying corridor sites.
The alternative pathway runs through structural acknowledgment of the long-term fuel volume decline and the offsetting c-store revenue growth. Modern institutional fuel retail underwriting increasingly assumes fuel volume runs flat to declining over the loan term while c-store revenue (particularly foodservice) compensates with structural growth. The cash flow projection at stabilization carries less fuel-revenue dependence than a 2015-vintage fuel-retail projection would have shown, and the loan structure accommodates the trajectory.
The feasibility documents the EV strategy explicitly. Sites pursuing EV charging integration document the capital plan, the NEVI or state-incentive eligibility, the projected EV-charging revenue contribution, and the integration with the c-store and fuel operations. Sites operating without EV integration document the projected fuel volume trajectory across the loan term and the c-store-revenue pathway that supports the underwriting through the EV transition. Either approach is acceptable to institutional reviewers — what is not acceptable is omitting the EV consideration entirely, because the lender's investment committee will examine the question regardless of whether the feasibility addresses it.
Five gas station sub-segments, each with a distinct study scope.
The gas station asset class spans five structurally distinct sub-segments, each with its own supply-agreement structure, capital cost basis, operating economics, and feasibility scope. The sub-pillar pages cover each in operational depth.
Branded major fuel retail — operating under long-term supply agreements with Shell, BP, Chevron, ExxonMobil, Phillips 66, Marathon, Sunoco, or similar major oil companies — represents the dominant institutional format in U.S. fuel retail. The format captures volume premium and c-store traffic from brand recognition at the cost of supply-pricing premium and operational brand-image commitments. Unbranded and independent operations — purchasing fuel from wholesale jobbers at rack pricing without long-term brand commitment — operate at lower volume but typically stronger fuel margin, dominating tertiary-market and rural site categories where branded major economics do not pencil.
C-store-anchored fuel retail — the modern format combining 4,000 to 6,000 square foot c-store with 8 to 12 fuel dispensers and frequently a branded QSR tenant integration — represents the dominant new-build format across both branded and unbranded operations. Truck-stop and travel-center formats — operating on interstate exits and major commercial-truck arterials with high diesel fuel volume, large-scale c-store and foodservice operations, and frequently overnight parking, shower facilities, and fleet services — operate on materially different scale and different demand-driver profile than light-vehicle fuel retail.
Gas plus car wash combination — integrating a fully featured car wash (typically express tunnel or in-bay automatic format) with the fuel retail and c-store operations on a shared site — has emerged as a recurring development pattern that captures dual-revenue contribution from a single site footprint. The combined format carries integration considerations across capital cost, operations, and traffic patterns that the feasibility addresses specifically.
