Restaurant Break-Even Analysis — How to Find Your Magic Number
Break-even is the sales figure where your restaurant stops losing money. Every dollar above it is profit. Here's how to calculate it and use it.
The Break-Even Formula
Two inputs, one output. Fixed costs are what you pay regardless of sales. Variable cost percentage is the share of every sales dollar consumed by variable expenses. The formula tells you how much you need to sell before what's left over from each sale finally covers all the fixed costs.
What Counts as Fixed vs. Variable
Fixed costs — the bills that don't change with sales
Rent, management salaries, insurance, loan payments, software subscriptions, base utilities, depreciation. These hit whether you sell 100 covers or 500. Add them all up for one month — that's your total fixed cost figure.
Variable costs — the ones that scale with sales
Food cost, hourly labor, credit card processing fees, delivery commissions, takeaway packaging, cleaning supplies that scale with volume. Express these as a percentage of sales. For most restaurants, this is roughly your prime cost (food + labor) plus 3–5% for card fees and other variable overhead.
Monthly Fixed Costs:
Rent: AED 35,000
Manager salaries: AED 18,000
Insurance: AED 2,000
Utilities (base): AED 4,000
Software & subscriptions: AED 1,500
Total Fixed: AED 60,500
Variable Cost % of Sales:
Food cost: 31%
Hourly labor: 22%
Card fees: 2.5%
Packaging & delivery: 3%
Total Variable: 58.5%
Break-Even: 60,500 ÷ (1 − 0.585) = 60,500 ÷ 0.415 = AED 145,783 / month
This restaurant needs to sell roughly AED 145,800 per month — about AED 4,860 per day — before it starts making any profit.

Higher rent = higher break-even
This is the biggest fixed-cost lever. A location with AED 10,000 more in monthly rent raises your break-even by roughly AED 24,000 in required sales (at 58.5% variable cost). Before signing a lease, run the break-even to see if the location can realistically generate the sales needed.
Lower variable cost % = lower break-even
Improving your prime cost from 58% to 53% (through better food cost control or tighter scheduling) drops your contribution margin from 42% to 47%. On AED 60,500 of fixed costs, that moves break-even from AED 144,000 to AED 128,700 — a AED 15,300 difference in required sales, from a 5-point improvement in cost control.
Adding a revenue stream = effectively lowering break-even
Catering, private events, delivery, and retail products don't change your fixed costs much but add revenue that contributes to covering them. This is why many restaurants that can't break even on dine-in alone become profitable once they add a meaningful delivery or catering channel.
Daily Break-Even — The Number Your Managers Should Know
Monthly break-even is useful for planning, but a daily number is what actually drives behavior. Divide monthly break-even by the number of trading days to get a daily target. Post it in the kitchen. When the team can see a number they need to hit today, decision-making gets sharper — managers cut a staff member when it's slow, push upsells when they're close, and don't over-order for a quiet Tuesday.
Break-Even for a New Restaurant
Pre-opening break-even analysis is one of the most valuable exercises you can do before committing to a location. Estimate your fixed costs from the lease, buildout financing, and staffing plan. Estimate your variable cost % from your menu costing and labor model. Then ask: can this location realistically generate enough sales to break even within 3–6 months? If the answer isn't a confident yes, the location might not be viable regardless of how good the concept is.
A worked example
A 60-cover neighbourhood restaurant carries monthly fixed costs of $28,000: rent $11,000, salaried management $9,500, insurance $1,200, loan repayment $3,300, subscriptions and licences $1,200, professional fees $1,800.
Variable costs run at 62% of sales — food cost 30%, hourly labor 26%, card fees and consumables 6%. The contribution margin ratio is therefore 1 − 0.62 = 0.38.
Break-even sales are $28,000 ÷ 0.38 = $73,684 per month. That is roughly $2,456 per day, or about $17,000 a week. At a $38 average check, the restaurant needs approximately 65 covers per day simply to stand still.
The value of running this calculation is how it reframes a quiet week. At $15,000 of weekly sales the instinct is to call it "a bit slow". The break-even figure says it was a $2,000 loss, and that demands a response rather than a shrug.
What break-even analysis cannot tell you
It is a planning tool built on assumptions, and being clear about its limits keeps it useful:
- It assumes your variable cost ratio holds steady as volume changes, which is only approximately true.
- It ignores seasonality. Most restaurants sit comfortably above break-even in strong months and below it in weak ones; the annual picture is what matters.
- It measures accounting profit, not cash. You can be above break-even and still short of cash when loan principal or tax payments fall due.
- It says nothing about whether the resulting profit is an adequate return for the capital and risk involved.
Most importantly, break-even is a floor rather than a target. A business that merely breaks even is not a viable business — set your operating goal meaningfully above the line and treat break-even as the alarm threshold.
When break-even looks impossible
Occasionally the calculation returns a number the site cannot physically reach. Compare the required cover count against your actual seating and realistic table turns: if break-even needs more covers than the room can seat in a service, the problem is structural.
No amount of operational tightening fixes that. The honest options are renegotiating rent, materially raising the average check, adding a revenue stream that uses the same fixed base, or accepting that the site is not viable at its current cost structure. Discovering this early is considerably cheaper than discovering it after two years of losses.
Frequently asked questions
How do you calculate a restaurant's break-even point?
Divide total fixed costs by the contribution margin ratio, which is 1 minus variable costs as a share of sales. Fixed costs of $30,000 with variable costs at 65% of sales gives $30,000 / 0.35 = $85,714.
Should the owner's salary be included in fixed costs?
Yes, if the owner works in the business. Excluding it produces a break-even point that only looks achievable because someone is working unpaid.
How often should break-even be recalculated?
Quarterly under stable conditions, and immediately after a rent review, menu reprice, change in salaried headcount, or a shift in food or labor cost percentage.
How do delivery commissions affect break-even?
Commissions of 20-30% are variable costs that reduce contribution margin sharply. If delivery is a meaningful share of revenue, calculate its contribution margin separately.
What is the difference between break-even point and payback period?
Break-even point is the monthly sales level covering operating costs. Payback period is how long cumulative profit takes to repay the initial fit-out investment.
Can a restaurant lower its break-even point quickly?
Raising the contribution margin through repricing usually acts faster than reducing fixed costs, since rent and salaries are contractually slow to change.
