How to Value a Gas Station, Step by Step
Separate the income streams, normalise the earnings, reserve for the equipment, then value the real estate on its own.

Step 1 — Assemble the file
- Three years of profit and loss statements and matching tax returns
- Monthly gallons and fuel margin for at least the last twelve months
- Inside sales by category, with margins
- The fuel supply agreement, including term and assignment terms
- Tank registration, testing and monitoring records
- Equipment list with ages: dispensers, canopy, coolers, wash, kitchen
- Lease or property assessment record
Step 2 — Separate the income streams
Build a simple table with fuel, inside sales, and any car wash, kitchen or service income on separate lines, each with its own revenue, cost of goods and direct costs. This is the step most owners skip, and it is the step that makes every later number defensible.
Step 3 — Normalise the earnings
Add back the owner's compensation, personal expenses, interest, depreciation and genuine one-off costs. Then subtract a realistic manager's wage if the owner currently covers shifts, and subtract an annual reserve for equipment that will need replacing. A car wash without a maintenance reserve flatters earnings in exactly the way a buyer will correct.
Step 4 — Apply a multiple and build a range
| Stream | Treatment | Note |
|---|---|---|
| Fuel margin | Include in earnings at a normalised cents per gallon | Avoid pricing off an unusually strong margin year |
| Inside earnings | Multiple applied as for any retail store | Mix and margin drive this more than revenue |
| Car wash | Earnings less equipment reserve | Reserve is not optional |
| Real estate | Valued separately | Never folded into the business multiple |
Step 5 — Deal with the site itself
Tank age and material, monitoring records, dispenser age and payment compliance, canopy condition, lot drainage and the state of the building all feed into a buyer's number. So does the property: if you own it, reference the public assessment record and treat it as a separate asset, not as part of the business price.

Common questions
- How many months of fuel data does a buyer need?
- Twelve months as a minimum and twenty-four preferably, broken down by month, so seasonality and price volatility are both visible.
- Should a car wash be valued separately?
- Value its earnings separately and set aside a realistic reserve for the equipment. Wash equipment is expensive to replace and buyers price that risk.
- What environmental work is normal?
- A Phase I environmental site assessment is standard on any fuel site. It is a records and site review, not drilling. A Phase II only follows if the Phase I identifies a concern.
