Restaurant Break-Even Analysis Explained

A restaurant break-even analysis tells you exactly how much revenue you need to cover all your costs — the point where you're neither losing money nor making it. Every dollar above break-even is profit; every dollar below it is loss. Knowing this single number changes how you think about a slow Tuesday, a new hire, or a rent increase, because you can measure each decision against the sales it demands.

The break-even formula

Break-even in dollars is built from three inputs:

Break-Even Sales = Fixed Costs ÷ Contribution Margin %

• Fixed costs are the bills that don't change with how busy you are: rent, insurance, salaried management, loan payments, and your base technology costs.
• Contribution margin is the share of each sales dollar left after variable costs (food and hourly labor) to put toward fixed costs and profit.

Contribution margin % = (Sales − Variable Costs) ÷ Sales.

A worked example

Say your monthly fixed costs are $20,000. Your variable costs — food and hourly labor — run 60% of sales, so your contribution margin is 40% (0.40).

Break-even = $20,000 ÷ 0.40 = $50,000 in monthly sales.

That's the line. Here's how profit behaves around it:

Notice how fast profit grows once you clear break-even — because fixed costs are already covered, most of each additional dollar's contribution margin drops to the bottom line.

Turn it into a daily target

Monthly break-even is useful for planning, but your team runs on days. Divide by the days you're open:

$50,000 ÷ 26 open days ≈ $1,925 per day just to break even. Now a slow shift has a concrete meaning, and you can set daily sales goals your managers actually feel.

If you don't know your daily break-even number, you're flying a plane without an altimeter. You feel like you're up — but you can't be sure.

Three levers to lower break-even

A lower break-even point means you're profitable sooner and more resilient in slow months. Three ways to pull it down:

1. Cut fixed costs. Renegotiate rent, shop insurance, and audit subscriptions. Overpaying for a POS is a common hidden fixed cost — moving from a $470+/month legacy system to a free all-in-one like Cobblestone POS, which bundles online ordering, loyalty, scheduling, and reporting with no monthly fee, lowers fixed costs directly and drops your break-even.
2. Raise contribution margin. Better pricing and menu engineering lift the margin on each sale, shrinking the sales you need. See how to price your menu for profit.
3. Control variable costs. Tighter food cost and smarter scheduling widen your margin without touching a single price.

Use it before every big decision

Break-even isn't a one-time calculation — it's a lens. Thinking about adding a salaried sous chef? That raises fixed costs, which raises break-even; now you know the extra daily sales it must generate to pay for itself. Considering a rent renewal at a higher rate? Run the new number first. Pair this with your P&L statement and a restaurant budget, and you move from guessing to knowing.

Common questions

What is a typical restaurant break-even point? There is no universal number, but many independents break even at 60% to 75% of their current sales. If yours is above 85%, one slow month puts you in the red, and it is time to trim fixed costs.

Does break-even include my own salary? It should. Put a realistic owner wage in fixed costs; otherwise the analysis tells you the restaurant is fine while you personally are working for free.
