How to Calculate the Break-Even Point for a Restaurant
Last updated: May 14, 2026
The break-even point for a restaurant is the revenue you need in a given period to cover every dollar of cost — and the formula is straightforward: Fixed Costs ÷ Contribution Margin Ratio. For most independent full-service restaurants, that number lands somewhere between $60,000 and $130,000 per month, which translates to a daily target of roughly $2,000 to $4,300. If you don't know your exact number, you're flying blind every single shift.
Here's what it looks like with real numbers. Say your restaurant carries $38,000 per month in fixed costs — rent, insurance, salaried manager pay, equipment leases, and loan payments. Your total variable costs (food, beverage, hourly labor, paper goods, credit card fees) run about 62% of sales. That means your contribution margin ratio is 38% — for every dollar in revenue, $0.38 is left to pay down fixed costs after variables are covered. Break-even = $38,000 ÷ 0.38 = $100,000 per month, or roughly $3,333 per day. Before you've made a dollar of profit, you need to hit that number every single day you're open.
The contribution margin ratio is the number most operators haven't actually calculated. It's easy to confuse with food cost percentage, but they're different. Food cost is just one component of your variable costs. The contribution margin ratio captures everything that scales with sales — food, beverages, hourly labor (in most accounting approaches), paper goods, and payment processing fees — and tells you what percentage of every revenue dollar survives after those costs are covered. The higher that ratio, the faster each sales dollar contributes toward covering fixed costs and generating profit.
Below, this post breaks down how to correctly separate fixed from variable costs (the line isn't always obvious), how to calculate contribution margin across multiple revenue streams like food, bar, and catering, how to convert your monthly break-even into an actionable daily covers target, and what to do when your break-even is higher than your realistic sales volume can support.
How do you calculate the break-even point for a restaurant?
Use this formula: Break-Even = Fixed Costs ÷ Contribution Margin Ratio. The contribution margin ratio is 1 minus your total variable cost percentage. For a restaurant with $35,000/month in fixed costs and a 35% contribution margin ratio, break-even is $100,000/month — roughly $3,333/day. Divide by your average check to find the daily covers target.
Fixed vs. Variable Costs: Getting the Categories Right
Most break-even errors come from miscategorizing costs. If you dump utilities into "fixed" without splitting out the variable portion, or if you treat hourly labor as fixed because it feels stable, your numbers will be off. Here's how to sort it correctly.
| Cost Type | Fixed Examples | Variable Examples | Semi-Variable (Split) |
|---|---|---|---|
| Labor | Salaried managers, GM salary | Hourly line cooks, servers, dishwashers | Split by role |
| Utilities | Base monthly minimum | Overage above baseline | Split by usage |
| Rent / Lease | Base rent, triple-net expenses | Percentage-of-sales rent clauses | Usually fixed |
| Food & Bev | — | COGS — scales directly with sales | Always variable |
| Marketing | Monthly retainer, base ad spend | Promo discounts, comp meals | Depends on structure |
A practical approach: pull three months of P&L data and tag every line item as F (fixed), V (variable), or S (semi-variable). For semi-variable items like utilities, estimate what percentage moves with volume — typically 30–50% of a restaurant utility bill scales with how many covers you're doing. Put the fixed portion in fixed costs and the variable portion in your variable cost pool.
Calculating Your Contribution Margin — Step by Step
Use recent data — three months back is close enough to catch current food costs, labor rates, and any recent vendor price increases. Older data will make your break-even look better than it is.
For most full-service restaurants, this lands between 58% and 68% of total sales. If you're above 68%, something is out of line — usually labor or food cost.
Example: $186,000 in variable costs on $300,000 in sales = 62% variable cost ratio.
1 - 0.62 = 0.38 (38% contribution margin ratio). That 38 cents on every dollar is what's available to cover rent, insurance, your own salary, and — eventually — profit.
$38,000 ÷ 0.38 = $100,000/month break-even. Divide by days open in the month to get your daily floor.
$100,000/month ÷ 30 days = $3,333/day ÷ $28 average check = 119 covers per day. That's your operational target. Every shift, you should know whether you're tracking above or below it.
How Bar Revenue Changes the Math
If you run a meaningful bar program, calculate contribution margin separately for food and beverage, then blend them. Alcohol typically carries a 70–80% contribution margin ratio (COGS is 20–30%). Food usually runs 30–42%. When a third of your revenue comes from the bar, your blended contribution margin is considerably higher than if you ran food only — which is one reason bar-driven concepts can sustain higher fixed costs than food-only operations.
The same logic applies to catering. If your catering runs at 30% food cost and lower labor per dollar of revenue (because you're staffing for a banquet, not continuous table service), catering revenue contributes more per dollar to covering fixed costs than comparable in-house dinner revenue. It's worth calculating the contribution margin for each revenue stream separately before blending them into a single break-even formula.
Fryer oil is one of the sneakier variable costs in kitchens running commercial fryers — it can quietly add $800 to $2,000 per month in a high-volume fry station. Running the numbers in the Purimax frying oil cost calculator is a quick way to see exactly how much oil cost is embedded in your variable cost base, and whether there's room to tighten it.
Real Kitchen Example: 78-Seat Casual Dining in Nashville, TN
This was a full-service concept — American comfort food, full bar, dinner only Tuesday through Sunday with weekend lunch. The operator had been open three years and felt like the restaurant was "doing well" but couldn't explain why cash was always tight at the end of the month.
Here's what the break-even analysis revealed:
- Fixed costs: $47,200/month (rent was $14,000, which was high for the market — signed pre-COVID)
- Variable cost %: 66% (food at 32%, hourly labor at 28%, other at 6%)
- Contribution margin ratio: 34%
- Break-even: $47,200 ÷ 0.34 = $138,824/month
- Average monthly sales: $122,000
- Gap: $16,824/month below break-even
The restaurant felt busy because it was full on Friday and Saturday nights. But Tuesday through Thursday was running at 40% capacity. The operator had been treating weekend volume as a sign of overall health when it was actually covering for a very real midweek shortfall.
The fix was a combination: adding a Tuesday happy hour to drive bar revenue (higher contribution margin), running a prix-fixe Thursday dinner at $45/head (higher average check, lower labor per dollar), and renegotiating the equipment lease to save $800/month in fixed costs. Ninety days later, monthly sales were up to $136,000 — still not at break-even, but the gap was down to $2,824/month, which the strengthened bar program covered by the next quarter.
The lesson: break-even isn't just a planning tool. It's a diagnostic that tells you exactly how much of your problem is on the cost side versus the revenue side — and which levers are worth pulling first. Reducing variable costs like food waste or oil cost (see how to extend frying oil life in a commercial fryer) improves your contribution margin ratio and lowers your break-even without adding a single cover.
When Your Break-Even Is Too High to Hit
If your break-even calculation produces a daily sales number that's higher than what your space, concept, and market can realistically generate, you have a structural problem. You can't sales your way out of a lease that's too expensive for your location. But you have a few levers:
On the fixed cost side, the obvious target is rent — which is the one you usually can't change short of a lease renegotiation or buyout. But equipment leases, insurance, and certain contracted services can sometimes be renegotiated or restructured. A $1,000/month reduction in fixed costs lowers your break-even by $2,941/month at a 34% contribution margin ratio. That math is worth the phone call.
On the variable cost side, each percentage point you trim from your total variable cost percentage has a compounding effect. Dropping from 66% to 63% in variable costs raises your contribution margin ratio from 34% to 37% — at the same $47,200 in fixed costs, break-even drops from $138,824 to $127,568 per month. That's an $11,000 reduction in your revenue requirement without changing your menu or adding a cover.
- Calculate break-even monthly, not just at concept launch — costs change and so does your variable cost profile
- Set a daily sales floor number and post it where your managers can see it every shift
- Separate food and bar contribution margins — blending them hides where the real leverage is
- Review fixed costs annually — renegotiate equipment leases and service contracts whenever you can
- Target variable cost categories with actual volume, not percentage targets alone — know your dollar amounts
- Run break-even sensitivity: what happens to your floor if food cost rises 2 points? If labor rises one point?
What is a good contribution margin ratio for a restaurant?
For a full-service restaurant, a contribution margin ratio of 32–42% is typical, with 35–38% being a reasonable benchmark for a healthy casual dining concept. Bar-forward operations often run 45–55% blended because alcohol carries much lower COGS. Fast casual restaurants typically land at 28–36%. The higher your contribution margin ratio, the less revenue you need to break even against the same fixed cost base.
How do I use break-even analysis to make staffing decisions?
Convert your break-even to a per-shift revenue target and compare it against your scheduled labor cost for that shift. If a Tuesday dinner service needs $1,100 in revenue to break even and you're scheduling six hourly staff at $300 in labor, you need to bring in $1,400+ to justify the schedule. If Tuesday consistently runs at $900, cut a position or consolidate the shift. Break-even analysis makes scheduling decisions quantitative rather than gut-feel.
