Break-even analysis estimates the sales required to cover costs before profit. It helps restaurant owners understand whether current traffic, average check, contribution margin, and operating days are enough to support the business.
Restaurant break-even formula
Break-even sales are calculated by dividing fixed costs by contribution margin percentage.
Break-even sales = fixed costs ÷ contribution margin percentage
Contribution margin is the portion of each sales dollar left after variable costs.
Contribution margin percentage = 100% − variable cost percentage
If you want to include a target profit, add the target profit to fixed costs before dividing by contribution margin percentage.
Sales needed for target profit = (fixed costs + target profit) ÷ contribution margin percentage
Restaurant break-even example
If fixed costs are $38,000 per month and variable costs are 62% of sales, contribution margin is 38%. Break-even sales are $100,000 per month.
If the restaurant is open 26 days, that is about $3,846 per day. If the average ticket is $24, the restaurant needs about 160 orders or guests per day to break even.
Why break-even analysis matters
A restaurant can have good food, good reviews, and steady traffic but still struggle if fixed costs are too high or contribution margin is too low. Break-even analysis helps owners see whether the business needs more sales, better pricing, lower costs, higher average ticket, more catering, or tighter labor control.
Use the number daily
A monthly break-even number is useful, but a daily target is easier to manage. Convert the target into daily sales, checks per day, average ticket goals, catering targets, and weekly sales goals. Managers can use those numbers to understand whether the day is on track before the month is already over.
Common break-even mistakes
- Using food cost only instead of total variable costs.
- Underestimating fixed costs like rent, insurance, software, repairs, licenses, and loan payments.
- Forgetting merchant fees, delivery commissions, packaging, discounts, and waste.
- Using an average ticket that does not match the current menu or guest mix.
- Looking only at monthly break-even sales instead of daily and weekly targets.

What is restaurant break-even sales?
Restaurant break-even sales are the sales needed to cover fixed and variable costs before profit. Once sales pass break-even, the remaining contribution margin can start producing profit.
What are fixed costs in a restaurant?

What are variable costs in a restaurant?
Variable costs are costs that generally rise as sales rise, such as food, beverage, packaging, hourly labor, merchant fees, delivery commissions, discounts, and waste.
How do you calculate daily break-even sales?
Divide monthly break-even sales by the number of operating days. For example, $100,000 in monthly break-even sales divided by 26 operating days equals about $3,846 per day.
