## Gas Station & Convenience Store Model: How the Template Values Fuel and Retail Cash Flow

This gas station financial model template evaluates a multi-site fuel and convenience store operator over seven years. It shows how fuel volume, store traffic, product mix, and operating costs interact to produce cash flow and site value.

The template is designed for investors, operators, and analysts assessing a purchase, redevelopment, or operating plan.

### How Fuel Demand and Store Traffic Are Connected

The model begins with a store estate that rolls forward from opening plus new stores. Each site sells a set number of gallons per year, growing modestly.

- Those gallons translate into fuel transactions, and a fixed walk-in conversion rate turns a portion of those transactions into convenience store visits. A separate destination traffic line captures customers who never buy fuel.

- This structure mechanically links fuel volume growth to merchandise traffic growth, so a slow fuel year is also a slow store year, reflecting how these businesses operate on the ground.

### Why Fuel Margin Compresses Even When the Markup Is Fixed

Retail fuel price is set as wholesale cost plus a fixed cents-per-gallon markup. Wholesale cost inflates annually, but the markup never changes.

- Card processing cost is charged as a percentage of the dollar sale, so as the pump price rises, card fees consume a growing share of that fixed markup. The model computes net fuel margin per gallon by subtracting card cost from the gross markup.

- This mechanic causes net margin per gallon to decay over time purely from inflation, even though the operator's pricing decision remains constant.

### How Merchandise Mix and Cost Structure Shape Profitability

Convenience store revenue is built from four merchandise categories, each with its own cost ratio. Tobacco is the low-margin, high-volume category, while food service carries the highest margin.

- Over the forecast, the mix drifts slightly toward food service, so blended merchandise gross margin rises modestly. On the cost side, cashiers and managers scale with store count, while corporate headcount remains fixed.

- Card fees are charged separately on fuel and merchandise sales, and underground storage tank compliance costs scale with the number of tanks.

### What the Cash Flow and Valuation Outputs Show

The model produces an unlevered free cash flow bridge: net operating profit after tax, plus depreciation, less capital expenditure and changes in working capital.

- Working capital includes fuel and merchandise inventory, card settlement float, and payables.

- Discounting these cash flows at a weighted average cost of capital and adding a terminal value yields enterprise value, then equity value and value per share.

- A dashboard summarizes key metrics such as fuel gallons, net fuel margin per gallon, merchandise revenue, EBITDA, and enterprise value, allowing users to compare operating trends alongside the valuation output.

## A fixed markup against a percentage-based fee - the mechanic that defines the format

The pump price is wholesale cost plus a $0.20/gal markup that never changes in nominal dollars, but card interchange is priced as a percentage of that rising dollar figure. Net fuel margin per gallon is computed as an explicit helper-row difference - gross markup minus card cost per gallon - so the compression from $0.1336 to $0.1126 over seven years is fully auditable: card fees eat 33.2% of gross fuel margin in Year 1 and 43.7% by Year 7, purely from wholesale cost inflation moving through a percentage-based cost, with the operator's own pricing decision never changing.

## Convenience-store traffic is derived, not assumed

Every fuel transaction carries a walk-in conversion probability that becomes store traffic, topped up by a separate destination-traffic line for customers who never buy fuel - so a slow fuel year is mechanically a slow merchandise year too. Layered on top, the four-category merchandise mix (tobacco, packaged beverages & snacks, food service, grocery & other) drifts toward food service, the highest-margin category, so blended merchandise gross margin rises from 33.3% to 34.5% even as fuel margin compresses - the two halves of the P&L move for structurally different reasons.

## EBITDA margin dilutes even as EBITDA dollars grow - an honest, not smoothed, result

Because fuel-price inflation flows straight through to cost of goods sold under a fixed nominal markup, fuel revenue growth adds almost nothing to profit. As wholesale inflation compounds, EBITDA margin as a percentage of total revenue eases from 3.79% to 3.35% even while EBITDA dollars keep compounding at roughly 7%/yr ($1.64M to $3.05M). The dashboard reports both the margin trend and the dollar trend side by side so a reader can't mistake dilution in the ratio for eroding profitability.

### Assumptions

Every driver in one sheet: store network, fuel volume & pricing, traffic & basket, merchandise cost ratios, cost structure, tax, capital & working capital, valuation.

- Year-1 store count, new stores per year, tanks per store
- Gallons per store and growth, gallons per transaction, wholesale cost and inflation, the fixed CPG markup, card share and interchange rate
- Walk-in conversion rate, destination traffic, basket size and growth, category shares and mix drift

- WACC, terminal growth, net debt, shares

### Operations

Store roll-forward, fuel volume and pricing, card economics, store traffic, the merchandise mix, working capital, tanks and staffing.

- Stores roll forward opening + new = closing; fuel gallons per store x stores = total fuel volume
- Wholesale cost inflates annually; retail price = wholesale + fixed markup; card cost per gallon and net fuel margin per gallon
- Fuel transactions from gallons per transaction; walk-in and destination store traffic
- Four-category merchandise mix (tobacco, packaged beverages & snacks, food service, grocery & other) and basket size
- Working capital: fuel and merchandise inventory, card settlement float, less fuel and merchandise payables
- Tank count, cashier, manager and corporate headcount

### Revenue

Fuel sales and the four-category merchandise sales build.

- Fuel sales = gallons x retail price
- Merchandise basket revenue = store traffic x basket size, split across the four categories
- Merchandise sales subtotal and total revenue

### P&L

Revenue to net income with fuel and merchandise COGS as two derived flows.

- Fuel COGS = wholesale cost x gallons; merchandise COGS = each category's revenue x its own cost ratio
- Gross profit and blended gross margin %
- Fuel and merchandise card processing fees, headcount-driven labour, occupancy, utilities, UST compliance and environmental premiums, marketing, G&A and shrink to EBITDA
- Depreciation to EBIT, corporate tax, net income
- Margins, merchandise gross margin, net fuel margin per gallon and fuel revenue share KPIs, and an identity check that resolves to zero

### FCF

Unlevered free cash flow from EBIT to a discounted present value.

- EBIT less unlevered tax equals NOPAT
- Add back depreciation
- Less maintenance capex and new-store buildout capex
- Less the change in working capital
- Unlevered FCF, discount factor and PV

### Valuation

An unlevered DCF to enterprise value, equity value, and value per share.

- Sum of explicit PV plus the PV of a Gordon-growth terminal value
- Enterprise value less net debt equals equity value
- Value per share and an implied EV/EBITDA multiple

## Use cases

- **Intrinsic valuation of a fuel and convenience store operator:** Set the store growth path, fuel volume and pricing, the card economics, the merchandise mix and its drift, the cost stack and a WACC, and read enterprise value, equity value, value per share and an implied EV/EBITDA multiple off mature-year earnings.
- **Card-fee and wholesale-price sensitivity testing:** Flex wholesale cost inflation, the interchange rate, card share, or the fixed cents-per-gallon markup to see exactly how much faster or slower net fuel margin per gallon compresses, and how that flows through to blended EBITDA margin over the seven-year horizon.
- **Merchandise mix and staffing planning:** Flex the walk-in conversion rate, destination traffic, basket size, or the category mix drift toward food service to see how fast merchandise revenue and gross profit grow relative to the fuel business, and how store-count leverage on fixed corporate overhead offsets fuel-side margin dilution.

## Frequently asked questions

### What is a gas station financial model?

A gas station financial model captures the seven-year operating economics and intrinsic value of a multi-site fuel and convenience store operator - two businesses sharing one canopy. It rolls a store estate forward into fuel volume and pricing, prices card processing costs against a fixed cents-per-gallon markup, derives convenience-store traffic from fuel transactions, splits merchandise revenue across four categories, and discounts an unlevered free-cash-flow stream to enterprise value, equity value and value per share.

### Why does net fuel margin per gallon compress over time?

Because the operator's markup is fixed in cents per gallon, but credit-card interchange is charged as a percentage of the dollar price at the pump. As wholesale fuel cost inflates and the pump price rises with it, the dollar amount card processors take a cut of grows every year, even though the markup itself never changes. That percentage-based cost eats a growing share of a fixed-cents revenue line - net margin per gallon falls from $0.1336 to $0.1126 over the model's seven years with no change in the operator's own pricing decisions.

### Why does convenience-store revenue depend on fuel volume?

Because the model derives store traffic from fuel transactions via a walk-in conversion rate rather than assuming an independent customer count. A share of every fill-up becomes a store visit, topped up by a smaller destination-traffic line for customers who never buy fuel. This mechanically links the two engines: fuel volume growth from store openings and per-site gallon growth drives merchandise traffic growth even though no merchandise-specific volume assumption exists.

### Why does EBITDA margin dilute even as EBITDA dollars keep growing?

Because fuel revenue is dominated by wholesale cost pass-through - every dollar of wholesale-price inflation shows up as revenue, but almost none of it becomes profit under a fixed-cents markup. As that inflation compounds, revenue grows faster than the business's actual gross profit, so EBITDA margin as a percentage of total revenue eases from 3.79% to 3.35% even while EBITDA dollars compound at roughly 7%/yr on store growth and the merchandise mix shift. It is a genuine structural feature of a fuel-price-inflated revenue base, not a modeling error.
