Understanding Your Break-Even
Break-even is the floor, not the goal. Once you know how many covers you need to cover fixed costs, the question becomes: how many covers above break-even are you doing — and how much of that contribution margin is flowing to profit?
The fastest way to lower your break-even point is to reduce variable costs — particularly food cost, which is directly controllable through supplier pricing, portion control, and waste reduction.
How to Use This Calculator
Enter your monthly fixed costs (rent, insurance, loan payments, salaried labor), your average check per cover, and your variable cost percentage (food cost + hourly labor + supplies as a percentage of revenue). The calculator returns the monthly revenue, monthly covers, and daily covers needed to break even — the point where revenue exactly equals total costs.
Fixed costs are expenses that don't change with volume — rent is the same whether you serve 50 covers or 500. Variable costs scale with revenue — more covers means more food cost and more hourly labor. The break-even point is where the contribution margin from each cover (revenue minus variable cost) accumulates enough to cover all fixed costs.
What to Do With Your Break-Even Number
Break-even tells you the floor, not the goal. Compare your break-even covers to your actual daily cover count. If you're averaging 120 covers and break-even is 95, you have a 25-cover cushion — that margin is your profit. If break-even is 115 and you're doing 120, a slow Tuesday puts you underwater. The fastest way to lower your break-even is to reduce variable costs — particularly food cost, which you control directly through supplier pricing and portion discipline.

A 3-point food cost improvement on $50,000 monthly revenue is $1,500/month — directly reducing your break-even revenue requirement by that amount.

Frequently Asked Questions
What is a restaurant break-even point?
The break-even point is the revenue level at which total costs equal total revenue — you are neither profitable nor losing money. It is calculated as Fixed Costs ÷ Contribution Margin Ratio, where contribution margin = 1 minus your variable cost percentage.
What counts as a fixed cost for a restaurant?
Fixed costs are expenses that do not change with sales volume: rent, base manager salaries, insurance, utilities (base amount), loan payments, software subscriptions, and any other recurring costs. Variable costs — food, hourly labor, credit card fees — scale with revenue.
What variable cost percentage should I use?
For most full-service restaurants, variable costs (food cost + variable labor + supplies) run 60–70% of revenue. Use your actual prime cost percentage as a starting point and add any other variable costs like credit card processing fees (typically 2.5–3%).
How do I lower my break-even point?
Either reduce fixed costs (negotiate rent, refinance debt, reduce management overhead) or improve your contribution margin (lower food cost through supplier price comparison, adjust menu pricing, or shift menu mix toward higher-margin items).
