How to Value a Gas Station: EBITDA, SDE, Per-Gallon, and Cap Rate

Most owners overvalue the fuel and undervalue the store, and most first-time buyers do the reverse. Both are guessing. A gas station is really 2 businesses stacked on 1 site, a low-margin fuel operation and a high-margin convenience store, often sitting on a piece of real estate worth more than either. Pricing it correctly means knowing which of 4 methods applies to your deal and where the verified multiples actually land in 2026.

This guide walks through the EBITDA multiple, the SDE multiple, the per-gallon method, and the cap-rate method, the same 4 lenses a petroleum broker runs before quoting a number. We use only verified ranges and show you how to reconcile them into one defensible value. When you are ready to put numbers in, the free valuation calculator applies the same math instantly.

First, separate the 3 things you are actually valuing

You cannot price a gas station with a single multiple because you are buying up to 3 distinct assets. Confusing them is the most common valuation error.

• The business (going concern): fuel gross profit, inside sales, car wash, food service, and any jobber or supply income. This is what an EBITDA or SDE multiple is built on.
• The real estate: the dirt, the canopy, the MPDs, and the building. This trades on a cap rate, not a multiple.
• The inventory and fuel in the tanks: almost always sold at cost on top of the price, never baked into the multiple.

This split matters because the C-store drives roughly 30% of revenue but around 70% of profit, while fuel is the reverse. A buyer paying a real-estate cap rate for store goodwill, or a business multiple for prime corner dirt, will misprice the deal by 6 figures. Decide what is changing hands before you pick a method. Our valuation service page breaks down each component for your specific store.

Method 1: The EBITDA multiple (the broker standard)

EBITDA (earnings before interest, taxes, depreciation, and amortization) is the cleanest measure of what a station earns before financing and tax choices muddy the picture. It is the standard for stores doing real volume and for any deal a bank or private buyer underwrites. Recast the books first by adding back owner perks, one-time costs, and personal expenses to get true operating earnings.

The gas station EBITDA multiple depends entirely on what is included:

• Business only (no real estate): 2.5x to 4.0x EBITDA.
• Business plus real estate combined: 4.0x to 7.0x EBITDA. High-volume branded stores reach 6x to 7x, while rural or unbranded sites sit near 4x.
• Stabilized real estate with a strong tenant: about 8x EBITDA, ranging 7x to 9x in premium markets.

A station with $300,000 in recast EBITDA, real estate included, branded, and high-volume would land around $1.8M to $2.1M at a 6x to 7x multiple. Run your own number in the valuation calculator, then read how much gas stations make to sanity-check the earnings input.

Method 2: The SDE multiple (for smaller, owner-run stores)

For a single-store operation the owner runs personally, EBITDA understates the real benefit because it ignores the salary the owner takes out. SDE (seller's discretionary earnings) fixes that. SDE equals EBITDA plus the owner's salary, plus all discretionary and personal expenses that flow through the business. It answers the question a hands-on buyer actually cares about: how much total money will this store put in my pocket?

SDE is the right lens for most of the market, since about 60% of the roughly 152,000 C-stores in the US are single-store operators. The gas station SDE multiple runs 2.0x to 3.5x for smaller stores. A site generating $120,000 in SDE would price near $240,000 to $420,000 on the business alone, before real estate.

Use SDE for owner-operated corner stores and EBITDA once a store is large enough to run with hired management. Quoting an SDE multiple on an EBITDA figure (or vice versa) double-counts or omits the owner's pay and throws the value off badly. See is owning a gas station profitable for how owner pay factors into real take-home.

Method 3: The per-gallon method (the fuel-volume sanity check)

Petroleum buyers carry a fast rule of thumb that no other industry uses: value per gallon of monthly fuel throughput. It is a cross-check, not a primary method, but it instantly flags a station that is mispriced relative to its pump volume.

The range is $0.05 to $0.30 per gallon of monthly throughput. Where a store falls inside that band depends on margin, brand, location, and how much of the value is goodwill versus dirt. A busy urban station moving 100,000 to 150,000 gallons a month sits at the high end, while the average US station doing roughly 4,000 gallons a day (about 120,000 a month) anchors the middle.

Apply it as a gut check. If an EBITDA-based price implies $0.45 a gallon, something is off, the earnings are inflated or the multiple is too rich. If it implies $0.03, you may be looking at a bargain or a dying location. Volume alone never sets the price, because net fuel profit is only a few cents per gallon even though 2025 fuel gross margins averaged 40-plus cents. The inside store is where the money is. Learn why in how much a gas station costs.

Method 4: The cap-rate method (for the real estate)

When real estate carries the value, especially a net-leased property with a credit tenant, you price it on a cap rate, not a multiple. Cap rate equals net operating income divided by value, so value equals NOI divided by the cap rate. A lower cap rate means a higher price and a safer, more sought-after asset.

Verified 2026 cap rates for gas station and C-store real estate:

• National: about 5.6%, roughly 5.58% with fuel and 6.87% without fuel.
• By state: Florida tightest near 5.11%, Texas about 5.63%, the Carolinas 5.0% to 5.5%, Tennessee 5.4% to 5.75%, and weaker markets like Mississippi 6.0% to 6.5% and up.
• By tenant: Wawa 4.83% to 5.20%, 7-Eleven 5.00% to 5.40%, Murphy USA around 5.13%, and Circle K 5.35% to 5.65%.

A property throwing off $200,000 in NOI at a 5.6% cap is worth about $3.57M. Tenant credit and location move the cap rate more than anything else. Model it in the cap rate calculator, and for the full data set see gas station cap rates by state and the NNN listings page.

Reconciling the methods into one defensible number

No single method is correct. Professionals run all 4 and triangulate, weighting the one that fits the deal structure.

• Owner-operated single store, business only: lead with the SDE multiple (2.0x to 3.5x), cross-check against per-gallon.
• Larger store or small portfolio with management: lead with the EBITDA multiple (business 2.5x to 4.0x, combined 4.0x to 7.0x), cross-check per-gallon.
• Net-leased or investment-grade real estate: lead with the cap rate, then confirm the implied EBITDA multiple lands near 7x to 9x.

When the methods disagree by a wide margin, that gap is the negotiation. A high EBITDA value with a low per-gallon number usually means goodwill is being oversold. A tight cap rate with thin store earnings means you are paying for dirt, not income. Owner take-home reality check: a small-to-medium station owner often nets about $70,000 to $100,000 a year, ranging to $100,000 to $500,000 by site. A value that implies far more than the store can support will not survive a buyer's lender or a Phase I review. Reconcile honestly, then test the result in the valuation calculator.

What moves your number up or down

Two stores with identical EBITDA can be worth very different amounts. The adjustments below decide where inside each range you land.

• Brand and fuel supply: a strong brand and a clean jobber contract pull toward the top of the multiple. Unbranded and rural sites sit near the floor. See branded vs unbranded.
• Real estate ownership: owning the dirt versus leasing it is the single biggest swing, and it determines whether a cap rate even applies.
• Environmental status: underground storage tanks carry CERCLA strict liability, which is why many conventional banks avoid USTs entirely. A clean Phase I Environmental Site Assessment (ASTM E1527-21, $1,800 to $3,500, required for SBA fuel deals) protects value. A flagged site discounts it.
• Income quality: recurring food service, car wash, and lottery income raise the multiple. Volatile fuel-only income lowers it.
• Financeability: a deal that clears SBA 7(a) underwriting (max $5M, 15% minimum equity injection on special-purpose stations) sells faster and higher. Read SBA 7(a) loans for gas stations and buying a station with USTs.
