How this gas station valuation calculator works

The calculator builds an estimated seller discretionary earnings proxy from fuel gross profit, inside gross profit, other income, and operating expenses before owner pay and debt service. It then applies a reported sold-business SDE benchmark.

The sourced multiple

BizBuySell's gas-station valuation benchmarks report a 1.74x lower quartile, 3.00x median, and 5.6x upper quartile for sold gas-station businesses from 2021 through 2025. The reported sample overrepresents smaller owner-operator deals. The source measures SDE and excludes a separate value for owned real estate.

When annual SDE exceeds $250K

Results above $250K can vary widely from the reported median benchmark. Larger and manager-run stores may attract different buyers and can require a different earnings measure, so the result is paired with a broker opinion of value request.

Why real estate is separate

Owned real estate is excluded from the instant result. Its value depends on market rent, lease structure, tenant credit, location, and the applicable cap rate. Fuel supply terms, deferred maintenance, environmental conditions, and underground storage tank records also require a deal-specific review.

Why 3 or more sites stop the estimate

A portfolio can carry shared overhead, different property ownership by site, and buyer value that a single-store formula cannot measure. At 3 or more sites, the calculator opens a confidential portfolio-review form and does not display an instant number.

FAQ

Questions about this tool

Is this gas station valuation an appraisal?

No. It is a preliminary operating-business estimate using a reported sold-business SDE benchmark. A transaction opinion must review the station's financials, contracts, environmental file, and market.

What does the estimate include?

It estimates the operating business from an SDE proxy. Inventory, debt, equipment adjustments, deferred maintenance, environmental conditions, and owned real estate are outside the instant result.

How is owned real estate valued?

Owned real estate needs a separate analysis of market rent, lease terms, location, property condition, tenant credit, and cap rate.

Why does the calculator stop at 3 sites?

A multi-site group can have platform value, shared overhead, mixed real-estate ownership, and several possible sale structures. The portfolio branch collects the information needed for a confidential review.
