Profit Margin Calculator for Restaurants

Restaurant profit margins are thin — the National Restaurant Association puts industry-wide net margins at 3-9%, with full-service averaging 3-5% and limited-service 6-9%. The two metrics that drive that net: prime cost (food + labor as % of sales, target under 60%) and food cost percentage (target 28-32%).

Restaurant P&L is a different animal from generic retail because two cost lines — food and labor — are simultaneously huge, variable daily, and the operator's main lever. The industry has converged on prime cost (food cost + total labor including taxes and benefits, as a % of sales) as the single most important operating metric. Keep prime cost under 60% of revenue and the rest of the math usually works; let it drift above 65% and the venue loses money even on busy nights.

This calculator splits the analysis into the lines a restaurant operator actually tracks: - Food cost percentage: COGS food ÷ food sales. Target 28-32% full-service, 25-30% QSR - Beverage cost percentage: 18-22% beer, 22-28% wine, 18-24% spirits - Labor cost percentage: including FICA, workers' comp, and benefits. Target 28-35% depending on service model - Occupancy: rent + utilities + insurance. Should be ≤ 10% of sales; over 12% the lease is the problem - Net margin: what's left after everything

A common reason restaurants run unprofitable: they price the menu off food cost alone and forget that labor scales with covers, not revenue. A $14 burger at 30% food cost looks fine until you realise four-top tables tie up a server for an hour and labor cost balloons.

The calculator also outputs break-even cover count — how many guests per shift you need to clear fixed costs. Pair it with seat-turn rate to see whether the venue is geometrically capable of profit at current pricing, or whether menu engineering is needed (a price increase on items with the lowest cost-to-price ratio).

For US operators, the National Restaurant Association's annual Restaurant Industry Operations Report is the authoritative benchmark source. For UK operators, UKHospitality's quarterly tracker publishes comparable figures.
