Break-even is the sales level where you stop losing money and start making it. It falls when you raise the average check, lower your variable cost per guest, or trim fixed overhead - and knowing the daily cover count it implies turns an abstract target into something the floor can actually aim at on a given shift.
If break-even feels too high, the levers are fixed overhead, average check, and variable cost - and they're easier to move with the right system. A free MOS audit finds which one to pull first.

Frequently asked questions
How do I calculate a restaurant's break-even point?
Break-even sales = fixed costs / contribution margin ratio, where the contribution margin ratio is 1 minus your variable cost percentage. Divide that by your average check to get the number of covers (guests) you need, then by your operating days for a daily target.
What counts as a fixed vs. variable cost?
Fixed costs don't move with sales: rent, insurance, salaried staff, software, loan payments. Variable costs scale with each guest served: food and beverage cost plus variable (hourly) labor. Mixing the two up is the most common reason break-even math comes out wrong.
What is a healthy margin of safety?
Margin of safety is how far current sales sit above break-even, as a percentage. The more cushion the better; a thin margin means a slow month can tip you into a loss, which is why lowering break-even (higher check, lower variable cost, leaner overhead) matters.
