When Will My Restaurant Break Even? (Free Calculator!)

Thinking about break-even can feel like staring up at a mountain. It’s big, it’s scary, and it’s easy to feel stuck at the bottom, wondering if you’ll ever get there. That’s normal. Running a restaurant is a juggling act of staff schedules, food prep, inventory, happy customers, and everything else in between. The financial side often feels like a separate language.

Here’s the good news: breaking even doesn’t have to be abstract. You just need to break it down in restaurant speak. By looking at the numbers you already have, like sales, costs, and covers, you can see exactly what you need so for a restaurant break even and turn that mountain into a clear, step-by-step path. 

In this post, we’ll show you how to take your P&L, your daily sales, and your average check, and turn them into a plan that you can act on in small, digestible steps.

What Break-Even Really Means

Break-even is just the point where your sales pay for all your costs. No loss, no profit, just covered. It comes down to two things:

• Fixed costs: the bills you pay whether anyone shows up or not, like rent, insurance, some salaries, and loan payments.
  
• Variable costs: the costs that rise and fall with sales, like food, beverage, hourly labor, and credit card fees.
  

Here’s the simple formula most restaurant owners use:

Break-even monthly sales = Total monthly fixed costs ÷ (1 − variable cost percentage).

That “1 − variable cost percentage” is called your “contribution margin ratio,” but you don’t need to remember the name. Just think of it as “what’s left from every dollar of sales after you pay the variable costs.”

The Numbers You Need

Pull these from your P&L and POS for the last month or two:

• Your average monthly fixed costs (rent, utilities portion, salaried payroll, insurance, and other fixed costs)
• Your average variable cost percentage (food and beverage costs plus variable labor)
• Your average check size
• How many days are you open each month

If you’re still setting up, use conservative estimates. 

Turning Abstract Targets Into Tangible Goals

Say your monthly fixed costs are $40,000. Your variable costs average 60% of sales. Your average check is $30.

Here’s how it looks:

1. Contribution margin ratio = 1 − 0.60 = 0.40.
2. Break-even monthly sales = $40,000 ÷ 0.40 = $100,000.
3. Guests needed per month = $100,000 ÷ $30 = 3,333 guests.
4. Guests per day (assuming 30 operating days) = 3,333 ÷ 30 ≈ 111 guests per day.

So you’d need roughly $100,000 in sales, or about 111 covers per day at a $30 average check, just to cover your costs. That’s the kind of clarity that lets you plan and act with confidence.

Turning Break-Even Into Action

Calculating break-even only helps if it shows you what to do next.

Here are the levers you can pull:

1. Track a daily break-even target

Turn your monthly break-even sales into a daily target:
Daily target = Monthly break-even ÷ operating days.
Post this target where managers can see it and measure it daily.

2. Focus on prime cost first

Prime cost equals food and beverage cost plus total labor. The industry benchmark for prime cost is roughly 60% to 65% of sales. Tightening prime cost by even a few points lowers your break-even. 

Tactics include portion control, standardized recipes, tighter prep lists, and labor scheduling aligned to real demand.

3. Raise your average check smartly

A $1–$2 increase in average check can lower the covers you need. Try high-margin add-ons, limited-time pairings, or a bundled special that nudges spend without hurting cover count.

4. Reduce variable cost leaks

Waste, over-portioning, spoilage and theft all inflate variable cost. Use weekly inventory checks, track last-cost pricing in your POS, and lock down pars for perishable items.

5. Trim fixed costs where you can

Some fixed costs can be renegotiated. Negotiate lease deferrals or step rent, combine vendors, cancel unused subscriptions, and push for better payment terms with suppliers.

6. Improve throughput and covers

Operational tweaks often beat pricing or cuts. Optimize table turns, prep staging, and waitlist management so you convert walk-ins into seated guests faster.

Planning Your Runway

Time to break-even varies. It depends on startup cost, location, concept, and demand. Many restaurants don’t reach positive cash flow immediately. Calculate runway in months as:

Runway = Cash reserves ÷ Monthly net loss

If your monthly loss is $10,000 and you have $60,000 in cash, your runway is 6 months. Use that number to prioritize quick wins that reduce burn while you grow sales.
