Restaurant Break-Even Analysis: Find the Number That Keeps You in Business

Your restaurant break-even point is the single most important number in your operation. It tells you exactly how much revenue you need to cover all your costs — not make a profit, just survive. Every week you don't know this number, you're flying without instruments. This guide walks you through the calculation with a real example.

What Break-Even Actually Means

Your break-even point is the revenue level at which total income equals total expenses — zero profit, zero loss.

• Above break-even: you're making money
• Below break-even: you're losing money

Simple in theory. But most restaurant owners have never actually calculated it.

Step 1: Understand Fixed vs. Variable Costs

Before calculating break-even, split your costs into two buckets.

Fixed Costs

Fixed costs are expenses you pay every month regardless of revenue — whether you serve 200 covers or 2,000.

Examples:

• Rent / lease
• Management salaries
• Insurance
• Loan payments
• Accounting / legal fees
• Software subscriptions

Variable Costs

Variable costs change based on how much you sell.

Examples:

• Food cost (more ingredients when you serve more guests)
• Hourly labor (more staff on busy nights)
• Credit card processing fees (~2.5% of revenue)
• Supplies (to-go containers, napkins)

For break-even purposes, express variable costs as a percentage of revenue.

Step 2: The Break-Even Formula

Break-Even Revenue = Fixed Costs ÷ Contribution Margin %

Contribution Margin % = 100% minus your variable cost percentage.

If variable costs are 63% of revenue, your contribution margin is 37%. Every dollar of revenue leaves $0.37 to cover fixed costs and profit.

Step 3: A Real Restaurant Example

Maple Street Kitchen — 75-seat casual restaurant.

Monthly Fixed Costs:

Item	Monthly Cost
Rent	$8,500
Management salaries	$12,000
Insurance	$1,200
Loan payment	$2,500
Utilities (base)	$1,800
Software / POS	$400
Total Fixed Costs	$26,400

Variable Costs as % of Revenue:

Item	% of Revenue
Food cost	31%
Hourly labor	28%
Credit card fees	2.5%
Supplies	1.5%
Total Variable %	63%

Contribution Margin % = 100% − 63% = 37%

Break-Even = $26,400 ÷ 0.37 = $71,351/month

Maple Street needs $71,351 in monthly revenue just to break even.

Breaking It Down Into Daily Targets

$71,351 ÷ 30 days = $2,378/day

If Maple Street does 80 covers at an average check of $30: 80 × $30 = $2,400/day — barely above break-even.

That's a thin margin. One slow week, one staff callout, one bad Tuesday — and they're under break-even for the month.

Now you can ask the right questions:

• How many covers do we need tonight to break even?
• If we raise average check by $3, how does break-even change?
• What happens if rent goes up $500/month?

How to Lower Your Break-Even Point

Reduce fixed costs. Renegotiate rent at renewal. Restructure loan terms. Cut underused software. Every $1,000 in fixed cost reduction lowers break-even by ~$2,700 in required revenue (at 37% contribution margin).

Reduce variable costs. Lower food cost % from 31% to 29% and your contribution margin jumps from 37% to 39%. Break-even drops from $71,351 to $67,692 — same fixed costs, lower threshold.

Raise average check. A $2 increase in average check across 80 covers/day = $4,800/month in incremental revenue — with zero change in fixed costs.

FAQ

How do I calculate break-even for a new restaurant?

Estimate your fixed monthly costs (rent, staff, insurance, loan payments) and your target variable cost percentages. Apply the formula: Fixed Costs ÷ Contribution Margin %. Compare to realistic revenue projections.

What is a good contribution margin for a restaurant?

A healthy contribution margin for a full-service restaurant is 35–42%. Fast casual and QSR can run slightly lower (30–38%) due to higher food cost efficiency.

How often should I recalculate my break-even point?

Recalculate every time a major cost changes: rent increase, staff change, food cost spike. Quarterly is a good default cadence.

Conclusion

Your break-even point isn't a theoretical exercise — it's the number that determines whether opening tomorrow is worth it. Operators who know their break-even make confident decisions about pricing, staffing, and promotions. Operators who don't are guessing.

Run this calculation today. It takes 30 minutes and gives you clarity that lasts all year.
