Prime Cost Calculator

Calculate restaurant prime cost: food cost plus labor (wages, taxes, benefits). See prime cost %, food vs labor split, benchmark status, and optional target comparison.

Prime cost formula

Formula
Prime Cost = Food Cost + Labor Cost + Payroll Taxes + Benefits + Other Direct Labor
Prime Cost % = (Prime Cost ÷ Sales) × 100
Food Cost % = (Food Cost ÷ Sales) × 100
Labor Cost % = (Total Labor ÷ Sales) × 100

What it means

Prime cost combines your two largest controllable expenses. Include loaded labor — not just wages — for an accurate picture. Lower prime cost % leaves more room for overhead and profit.

Good to know

  • Food, labor, and sales cover the same time period.
  • Optional labor lines default to zero when left blank.
  • Rent, utilities, and marketing are not included in prime cost.

Ideal range

  • Does not calculate net profit or break-even.
  • Benchmark bands are guidelines — targets vary by concept and market.

Variables

Food costIngredient cost
Total food purchases and usage for the period.
Labor costLoaded labor
Wages plus payroll taxes, benefits, and other direct labor charges.
SalesRevenue
Food sales for the same period. Must be greater than zero.

Worked examples

Real numbers through the same formula this tool uses.

  1. 1
    Restaurant scenarioExample 1

    $10k food + $12k labor on $40k sales

    Prime cost = $22,000. Prime cost % = 55%. Food 25%, labor 30% of sales.

  2. 2
    Restaurant scenarioExample 2

    60% target on $50k sales

    Target prime cost budget = $30,000. Use as a spending cap for food plus labor.

How to use this calculator

Four steps from costs to prime cost %.

  1. Choose your mode

    Enter actual food, labor, and sales — or set a target prime cost % with sales.

  2. Enter food and labor

    Use P&L or POS reports. Add payroll taxes, benefits, and other direct labor if tracked separately.

  3. Enter total sales

    Food sales for the same period as your cost figures.

  4. Review benchmark and split

    Check prime cost %, food vs labor share, and benchmark status against the 55–65% typical range.

What is prime cost?

Prime cost is the combination of food cost and labor cost — the two largest controllable expenses in most restaurants.

  • Prime cost definition

    Prime Cost = Food Cost + Labor Cost (including payroll taxes, benefits, and other direct labor). Prime Cost % = Prime Cost ÷ Sales × 100.

  • Why prime cost matters

    Prime cost typically accounts for 55–65% of sales in full-service restaurants. What remains must cover rent, utilities, marketing, and profit.

  • Food share vs labor share

    The calculator shows each line as a percent of sales and as a share of total prime cost. A balanced split depends on your concept — fine dining may run higher labor; fast casual may run higher food cost efficiency.

  • Using target mode

    Set a target prime cost % and sales to see your prime cost budget in dollars. Enter actual food and labor to measure variance from target.

Best practices

How operators manage prime cost week to week.

  • Track prime cost weekly

    Waiting for month-end closes hides problems. Compare food and labor against sales every week using the same definitions.

  • Include loaded labor

    Wages alone understate labor. Add payroll taxes, benefits, and workers comp for a true prime cost picture.

  • Match the period

    Food cost, labor cost, and sales must cover the same dates. Mixing partial weeks distorts prime cost %.

  • Act on variance early

    When prime cost drifts above target, diagnose whether food purchasing, waste, scheduling, or sales softness is the driver — then fix the root cause.

Common mistakes

Errors that make prime cost misleading.

  • Counting wages only

    Excluding payroll taxes and benefits makes labor look cheaper than it is and understates prime cost.

  • Using all sales instead of food sales

    If you benchmark food cost on food sales only, use food sales for prime cost % too — or be consistent with your P&L definitions.

  • Missing overtime and bonuses

    Spikes in overtime or manager bonuses belong in labor cost for the period they hit — not smoothed away.

  • Setting targets without variance review

    A 60% target means nothing if you never compare actual prime cost and adjust scheduling or purchasing.
