4-Wall EBITDA Calculator

What 4-Wall EBITDA Measures

4-Wall EBITDA isolates the operational profitability of a single restaurant location. The name comes from measuring only what happens “within the four walls” of the store, excluding corporate overhead, depreciation, interest, and taxes. This makes it the cleanest measure of how well a restaurant converts revenue into cash flow at the unit level.

For franchise investors, 4-Wall EBITDA is the starting point for valuation. QSR franchise transactions typically trade at 4-6x store-level EBITDA, making a location with $400,000 in annual 4-Wall EBITDA worth roughly $1.6M-$2.4M as an operating asset. It is also the basis for calculating investment payback periods, which most franchise concepts target at 3-5 years.

The Four Cost Buckets

COGS (Cost of Goods Sold): Food ingredients, beverages, and paper/packaging products. This is the most directly controllable cost for operators through supplier negotiation, waste reduction, and menu engineering. Burger QSR concepts typically run 28-32%, while pizza concepts with high-margin beverages can achieve 25-28%.

Labor:Crew wages, management salaries, benefits, payroll taxes, and workers' compensation insurance. The largest variable cost and the hardest to optimize without affecting service quality. Minimum wage increases, overtime, and benefits mandates make this the fastest-growing cost line for most QSR operators.

Occupancy: Base rent, CAM charges, property taxes, and utilities. This is largely fixed, which creates operating leverage: a 10% revenue increase flows almost entirely to EBITDA because occupancy costs do not change. Conversely, revenue declines compress EBITDA margins quickly because occupancy remains constant.

Other Operating Expenses: Insurance, repairs and maintenance, local store marketing, supplies, technology costs, and franchise royalty fees. Royalties (typically 4-6% of gross revenue) are the largest single line item here for franchise operators.

Why Revenue Leverage Matters

The sensitivity analysis in this calculator demonstrates a critical concept in restaurant economics: operating leverage. Because occupancy costs are fixed, incremental revenue above break-even flows to the bottom line at a much higher margin than the overall EBITDA margin. A store with 20% EBITDA margin might see 35-40% incremental margins on same-store sales growth. This is why same-store sales comps are the most-watched metric in QSR investor earnings calls. It is also why revenue declines are so painful: losing 10% of revenue can cut EBITDA by 25-30% due to the fixed-cost floor.
