Restaurant break-even analysis explained

Break-even is the monthly sales figure at which total costs are covered and profit is zero. Most operators can quote last month's sales but not this number, which means they cannot tell on a Wednesday whether the week is working.

The calculation

Separate costs into fixed and variable. Fixed costs do not move with sales: rent and triple-net charges, insurance, management and salaried wages, loan payments, software subscriptions, base utilities. Variable costs move with sales: food and beverage cost of goods, hourly labor, credit card fees, and supplies.

Express variable costs as a percentage of sales. If food and beverage run 30 percent, hourly labor 22 percent, and cards and supplies 5 percent, variable cost is 57 percent, which leaves a contribution margin ratio of 43 percent.

Then: break-even sales equals fixed costs divided by the contribution margin ratio. With $38,000 in monthly fixed costs and a 43 percent contribution margin, break-even is $88,372 a month — roughly $2,946 a day on a 30-day month, or about $3,400 a day if you are closed Mondays.

Translate it into covers

A dollar figure is hard to manage against on a shift. Divide by average check. At a $38 average check, $3,400 a day is 90 covers. That is a number a manager can hold in their head at 6pm and act on.

Include the owner's wage

Break-even without owner compensation is a break-even on paper only. Put a market-rate salary for your own role in fixed costs. The resulting figure is the honest one, and it is usually 8 to 15 percent higher than what operators first calculate.

What to do with the number

Post the daily break-even cover count where the management team sees it. Compare actual covers to it every day, not every month. Once you have it, target profit is one step away: add the profit you want to fixed costs and divide again. Wanting $6,000 a month on the example above means $102,326 in sales, or about 105 covers a day.

The three levers that move it

Lower fixed costs — renegotiate rent at renewal, re-quote insurance and waste hauling, right-size salaried headcount. Improve contribution margin — re-cost recipes, adjust menu pricing, shift mix toward beverage and high-margin items, tighten hourly scheduling against forecast. Raise average check — attachment, coursing, and menu structure rather than across-the-board price rises.

Recalculate break-even whenever rent, wages, or major supply costs change, which in practice means quarterly. It is the fastest sanity check in the business: if you are not clearing it, no marketing campaign is going to fix the arithmetic.
