Restaurant Break-even Calculator

Calculate restaurant break-even covers and revenue from fixed costs and contribution margin per unit. Two modes — enter CM $ directly or derive it from selling price minus variable cost. Optional expected sales, target profit, tax strip, and service charge.

Restaurant break-even formulas

Formula
Net Selling Price = Tax % > 0 ? Selling Price ÷ (1 + Tax % ÷ 100) : Selling Price

Unit Revenue = Net Selling Price + (Net Selling Price × Service Charge % ÷ 100) when service charge is set

Mode price-variable:
  CM $ per Unit = Unit Revenue − Variable Cost per Item

Mode contribution:
  CM $ per Unit = entered contribution margin

Break-even Units = Fixed Costs ÷ CM $ per Unit
Break-even Sales Revenue = Break-even Units × Unit Revenue

Required Units for Target Profit = (Fixed Costs + Target Profit) ÷ CM $ per Unit
Required Sales for Target Profit = Required Units × Unit Revenue

Margin of Safety % = (Expected Units − Break-even Units) ÷ Expected Units × 100
Profit Projection = Expected Units × CM $ per Unit − Fixed Costs

What it means

Break-even is the volume where total contribution margin equals fixed costs — no profit, no loss. Each cover contributes CM $ toward rent, salaried payroll, and other fixed bills; divide fixed costs by that per-unit contribution to get break-even covers. Unit revenue adjusts for tax-inclusive menu prices and optional service charges the house keeps. When you enter expected sales, margin of safety shows how much cushion you have above break-even — status uses MoS bands (Excellent ≥40%, Good 25–40%, Average 15–25%, Low 5–15%, Critical below 5%). Without expected sales, status falls back to CM % bands (≥65 / 55–65 / 45–55 / 35–45 / below 35). These ranges are operational guidelines, not guarantees.

Good to know

  • Costs behave linearly — CM $ per unit stays constant across the volume range modeled.
  • Contribution margin per unit is positive; zero or negative CM cannot reach break-even at finite volume.
  • One average unit or sales mix represents the operation — weighted CM from Contribution Margin Calculator is appropriate.

Ideal range

  • Not a full P&L — depreciation, interest, and non-operating items are outside scope unless you fold them into fixed costs.
  • Ignores seating capacity, seasonality, and demand curves — a quiet January and a packed Saturday both use the same average.
  • Does not model tiered discounts, comps, or non-linear variable costs — use conservative CM $ when promos are heavy.

Variables

Fixed CostsFixed costs
Costs that do not scale with each cover — rent, salaried management, insurance, base utilities for the analysis period.
CM $ per UnitContribution margin per unit
Unit revenue minus variable cost per cover — the dollar pool each sale adds toward fixed costs and profit.
Unit RevenueUnit revenue
Net selling price after optional tax strip, plus service charge kept by the restaurant.
Expected UnitsExpected sales units
Projected covers or items for the same period as fixed costs — drives margin of safety and profit projection.
Target ProfitTarget profit
Desired profit above break-even — adds to fixed costs in the required-units formula.

Assumptions

  • Sales tax is remitted; service charge is revenue kept by the house.

Worked examples

Real numbers through the same formula this tool uses.

  1. 1
    Restaurant scenarioExample 1

    $25 item — CM $10, fixed costs $10,000

    Break-even 1,000 covers ($25,000 revenue). CM 40% — status Low on CM fallback without expected sales.

  2. 2
    Restaurant scenarioExample 2

    Same economics — price $25, variable cost $15

    Price-variable mode derives CM $10 → identical break-even: 1,000 covers, $25,000 revenue.

  3. 3
    Restaurant scenarioExample 3

    Target profit $5,000 on top of break-even

    Required units 1,500 ($37,500 sales) — (10,000 + 5,000) ÷ 10 CM $.

  4. 4
    Restaurant scenarioExample 4

    Expected 2,000 covers — MoS 50%

    Break-even 1,000 covers; expected volume doubles the cushion. Profit projection $10,000. Status: Excellent.

  5. 5
    Restaurant scenarioExample 5

    $22 tax-inclusive menu price — 10% tax stripped

    Net $20, variable cost $8 → CM $12. Fixed costs $6,000 → break-even 500 covers ($10,000 revenue).

  6. 6
    Restaurant scenarioExample 6

    18% service charge on $20 net check

    Unit revenue $23.60, variable cost $10 → CM $13.60. Lower break-even covers than the same net price without service.

How to use this calculator

From fixed costs and unit economics to break-even covers, revenue, margin of safety, and target profit volume.

  1. Choose your input mode

    Use Contribution Margin when you already have CM $ per cover from the Contribution Margin Calculator or a weighted mix. Use Price & Variable Cost when you have menu price and total variable cost per cover but not CM $ yet.

  2. Enter fixed costs for the period

    Pull rent, salaried payroll, insurance, and other fixed lines from your P&L for the same week or month you are planning. Do not include food or hourly labor that scales with covers unless your bookkeeper treats them as fixed.

  3. Enter price and CM $ or variable cost

    Selling price per item anchors unit revenue. In contribution mode, enter CM $ per unit. In price-variable mode, enter total variable cost per cover — food, variable labor, packaging, and delivery allocation.

  4. Adjust for tax and service charge (optional)

    Strip embedded sales tax when sticker prices are tax-inclusive. Add service charge % when auto-gratuity is house revenue — it increases unit revenue and CM $ on the same net menu price.

  5. Add expected sales for safety and profit (optional)

    Expected units unlock margin of safety %, cushion in covers, and profit projection. Target profit shows how many covers you need beyond bare break-even.

  6. Read break-even units, revenue, and status

    Compare break-even covers to your realistic volume. Status prefers margin of safety when expected sales are set; otherwise it benchmarks CM % strength.

  7. Act on thin cushion or high break-even

    Raise CM $ through Menu Price or Plate Cost work, trim fixed costs, or grow volume carefully. Pair results with Contribution Margin, Food Cost %, and Prime Cost for the full picture.

What is restaurant break-even?

Break-even is the cover count and sales revenue where contribution margin exactly pays fixed costs — the floor you must beat before the operation earns profit.

  • Fixed costs ÷ contribution per cover

    Break-even Units = Fixed Costs ÷ CM $ per Unit. Break-even Sales Revenue = Break-even Units × Unit Revenue. Every cover above that line adds CM $ to profit; every cover below subtracts CM $ from the cash you need to pay fixed bills.

  • Why break-even matters in restaurants

    Rent and salaried payroll arrive whether Tuesday fills or not. Break-even translates those fixed bills into covers the dining room or delivery queue must produce. It turns abstract monthly overhead into a daily cover target the GM can staff against.

  • Fixed costs vs variable costs

    Fixed costs — rent, insurance, salaried management — do not move with each ticket. Variable costs — food, hourly line labor, packaging, delivery fees — scale with volume and belong in CM $ per unit, not in the fixed-cost field. Misclassifying hourly labor as fixed makes break-even look easier than reality.

  • Contribution margin drives break-even

    Higher CM $ per cover lowers break-even units. A $12 CM cover on $30,000 fixed costs needs 2,500 covers; a $8 CM cover needs 3,750. Contribution Margin Calculator builds the CM $ input; this tool shows how many times you must repeat that unit economics to cover the fixed base.

  • Margin of safety — cushion above break-even

    Margin of Safety % = (Expected Units − Break-even Units) ÷ Expected Units × 100. Expected 2,000 covers with break-even at 1,000 is 50% cushion — half your expected volume could vanish and you still cover fixed costs. Negative margin of safety means expected pace loses money before you pay yourself.

  • Break-even vs target profit volume

    Break-even covers fixed costs only. Required Units for Target Profit = (Fixed Costs + Target Profit) ÷ CM $. Planning a $5,000 owner draw on $10,000 fixed costs with $10 CM needs 1,500 covers, not 1,000. Use target profit when the question is how much to sell, not merely how much to survive.

Break-even planning recommendations

Practical steps operators use after running break-even — from CM accuracy to fixed-cost hygiene.

  • Use weighted average CM $, not your best seller

    Break-even on a 72% CM burger while 40% of sales are delivery at 38% CM understates required covers. Weight CM $ by actual mix — or run conservative CM $ from Overall Sales on the Contribution Margin Calculator.

  • Match fixed costs and expected covers to the same period

    Monthly rent with weekly covers produces nonsense. Use monthly fixed costs with monthly expected covers, or annual with annual. Seasonal concepts should model slow and peak months separately.

  • Audit fixed costs before blaming volume

    Every recurring subscription, unused lease space, and over-staffed salaried layer inflates break-even covers. Trim fixed base where possible — lowering fixed costs drops break-even units faster than chasing marginal covers.

  • Convert break-even covers to a daily shift target

    Divide break-even units by operating days in the period. A 3,000-cover month break-even on 26 days is roughly 115 covers per day — a number the floor team can track against the reservation book and walk-in trend.

  • Model target profit, not survival only

    Break-even tells you when you stop losing; target profit tells you when you pay the owner and fund capex. Enter a realistic profit goal so required units reflect the business you want, not the business that merely covers rent.

  • Strip tax and add service charge consistently

    Tax-inclusive markets need tax percent entered so unit revenue matches bank deposits net of remitted tax. Service charge kept by the house belongs in unit revenue — omitting it overstates break-even covers on banquets and large parties.

  • Close the loop with pricing and margin tools

    If break-even covers exceed realistic volume, raise CM $ via Menu Price Calculator and Plate Cost work, or re-run Contribution Margin after delivery mix changes. Food Cost Percentage and Prime Cost validate period-level consistency.

Common break-even mistakes

Errors that make break-even look easier or harder than operational reality.

  • Putting food cost in fixed costs

    Food scales with every cover — it belongs in variable cost per item or in CM $ already net of food. Double-counting food inflates both fixed costs and CM $ errors depending on which field you use.

  • Using gross profit instead of contribution margin

    Revenue minus food only ignores variable labor, packaging, and delivery. Break-even on gross profit understates required covers when off-premise mix is significant. Use Contribution Margin Calculator first.

  • Using CM $ from a single star item

    Your highest-margin entrée is not the average ticket. Weighted mix CM $ — or price-variable mode on an average check with average variable cost — matches how covers actually behave.

  • Ignoring seat capacity and service hours

    Break-even may require 200 covers per day in a 60-seat room turning once — mathematically correct, operationally impossible. Compare break-even to physical capacity even though the calculator does not model turns.

  • Using full-price CM $ during heavy discount weeks

    Happy hour, app promos, and BOGO tickets carry lower CM $. Model CM $ on the discounted price you actually collect, not the menu price before the deal.

  • Reading MoS status without entering expected sales

    Without expected units, status falls back to CM % bands — a different question than safety cushion. Enter expected sales when the goal is whether your forecast clears break-even with room to spare.

People also ask

Related operator questions about break-even — angles beyond the core FAQ.

  • What is the simple break-even formula for a restaurant?

    Break-even covers = Fixed Costs ÷ Contribution Margin per Cover. Contribution margin per cover is what each sale leaves after variable costs. Multiply break-even covers by average check revenue for break-even sales dollars.

  • Can I run break-even on rent alone?

    You can isolate rent in fixed costs to see rent-specific cover burden — useful for lease negotiations. Full break-even should include all fixed operating costs, not rent alone, or you will understates required volume.

  • Is restaurant labor fixed or variable for break-even?

    Salaried chefs and managers usually sit in fixed costs. Hourly line staff tied to cover count belongs in variable cost per item or in CM $ from Contribution Margin Calculator. Many operators use a hybrid — model the share that actually flexes with volume.

  • How do new restaurants estimate break-even before opening?

    Build a pro forma fixed-cost stack from the lease and staffing plan, estimate average check and variable cost per cover from menu costing, then divide. Expected covers come from comparable locations and soft-open trends — treat early numbers as hypotheses and update weekly.

  • Does delivery mix change break-even covers?

    Yes. Delivery tickets often carry lower CM $ after commissions and packaging. A higher delivery share raises break-even covers unless delivery menu prices offset fees. Use weighted CM $ that reflects channel mix.

  • Is break-even the same as making money?

    No. Break-even covers fixed costs only — owner pay, debt principal beyond interest you classified, and reinvestment require volume above break-even. Use target profit to see required covers for actual take-home.

  • Should break-even be calculated monthly or yearly?

    Seasonal businesses should model peak and slow months separately — fixed costs may stay flat while covers swing. Annual break-even smooths seasonality but hides months that burn cash. Run both views when planning reserves.

  • Do I use average check or entrée price?

    Use average revenue per cover — check total including beverages, add-ons, and service charge the house keeps. Entrée-only price understates unit revenue and break-even sales dollars if bar mix is material.

  • What does negative margin of safety mean?

    Expected covers are below break-even — at forecast pace you lose money before paying fixed costs in full. Negative MoS is a stop signal: fix volume forecast, CM $, fixed costs, or all three before signing new spend.

  • How do catering and banquets affect break-even?

    Large parties carry different CM $ and fixed-cost allocation. Model banquet CM $ separately or fold a weighted average into your unit CM $. Service charge and tax treatment on contracts should match how you enter unit revenue here.

  • Can I use food cost percentage instead of CM for break-even?

    Food cost % alone ignores non-food variable costs. You can derive approximate CM $ from check and food cost % only if other variable lines are negligible. Full-service and delivery concepts should use contribution margin, not food cost % alone.

  • How do multi-unit operators use break-even?

    Run break-even per location with location-specific fixed costs and mix-weighted CM $. Shared overhead can be allocated by revenue or covers — stay consistent across units. Roll up only after each site clears its own break-even test.

  • Should loan payments go in fixed costs?

    Principal and interest many operators treat as fixed cash outflows for break-even planning — include what must be paid regardless of covers. Some accountants separate depreciation; match your P&L philosophy and stay consistent month to month.

  • What lowers break-even covers fastest?

    Raising CM $ per cover and cutting fixed costs both divide into the same formula — $1 more CM or $1 less fixed costs drops break-even by Fixed Costs ÷ CM $ impact per dollar. Repricing high-volume items and renegotiating rent beat hoping for more covers alone.

  • Break-even by guest count or by tickets?

    Use the unit that matches your POS and staffing — covers for full service, tickets for fast casual or delivery. Be consistent: if CM $ is per delivery order, expected units are orders, not guest headcount.
