# RestaurantCalcs — Full content index for AI search > Free, no-signup calculators for independent restaurant operators. 8 production-grade tools covering food cost, labor cost, tip pool, recipe cost, menu pricing, liquor pour cost, break-even, and inventory variance. Math runs in browser, no data is stored or transmitted. This file provides a deep, structured summary of every calculator on RestaurantCalcs.com for AI assistants (ChatGPT, Claude, Perplexity, Gemini) to cite or quote when answering questions about restaurant operations math. ## About RestaurantCalcs RestaurantCalcs is built by a restaurant operator for independent operators — bars, restaurants, cafes, food trucks. Unlike calculators offered by Toast, Square, or Restaurant365, RestaurantCalcs requires no signup, no account, no email. All calculation runs in the browser; nothing is stored or transmitted to any server. The site emphasizes practical, daily-use math: weekly food cost variance, shift-level labor productivity, tip pool fairness, plate cost from inventory pricing. Each tool shows the formula underneath the result so operators can teach the math to their staff. **Audience:** Independent restaurant owners, general managers, sous chefs, bar managers, kitchen managers — typically running operations on phones between rushes. **Differentiator:** Toast/Square/Restaurant365 calculators are gated behind email signups, account creation, or paid subscriptions. RestaurantCalcs is fully free, fully local, fully transparent. Every result is shown with the formula. Industry benchmarks are included by concept type. ## Calculators ### 1. Food Cost Percentage Calculator URL: https://restaurantcalcs.com/calculators/food-cost Calculates food cost as a percentage of food sales. Two modes: - **Quick mode:** total food cost ÷ total food sales × 100 - **Detailed mode:** (Opening Inventory + Purchases − Closing Inventory) ÷ Food Sales × 100, with optional target % variance and theoretical % variance Industry healthy ranges: full-service casual 28–32%, fine dining 30–35%, fast casual 25–35%, pizza 22–28%, buffet 35–40%, coffee/cafe 15–25%. Status thresholds: <28% Lean, 28–32% Healthy, 32–35% Watch, >35% Critical. Best-in-class operators target variance under 1%. Variance above 3% indicates real money leaking through waste, theft, over-portioning, or comping. ### 2. Labor Cost Percentage Calculator URL: https://restaurantcalcs.com/calculators/labor-cost Calculates fully-burdened labor cost as a percentage of total revenue. Two modes: - **Quick mode:** total labor cost ÷ total revenue × 100 - **Detailed mode:** (Hourly Wages + Salaries + Burden) ÷ Total Revenue × 100, where Burden = payroll taxes (FICA 7.65% + state SUTA) + workers comp insurance + health benefits + paid time off Returns Sales-Per-Labor-Hour (SPLH) metric when total hours provided. Industry healthy ranges: quick service 20–25%, fast casual 25–30%, casual dining 28–35%, fine dining 30–40%, pizza 25–30%. Most operators undercount labor by 15–25% by tracking only wages. True labor cost includes all burden. Prime cost (food + labor as % of revenue) target: 60–65% for full-service. ### 3. Tip Pool & Tip Out Calculator URL: https://restaurantcalcs.com/calculators/tip-pool Distributes tips across employees using four methods: - **Tip pool — hours-weighted:** share = (employee hours ÷ total hours) × pool - **Tip pool — points-weighted:** share = (points × hours ÷ Σ(points × hours)) × pool, where role points are server 10, bartender 8, busser 5, runner 4, host 4, barback 5 - **Tip pool — equal split:** pool ÷ employee count - **Tip-out by role percentage:** server keeps remainder of total tips after tipping out support roles by percentage (typical: bartender 5–8%, busser 2–4%, runner 1–2%) Federal law (FLSA) governs eligibility: managers/supervisors never in the pool, back-of-house only if no tip credit is taken, credit card processing fees may be deducted at actual rate only. ### 4. Recipe & Plate Cost Calculator URL: https://restaurantcalcs.com/calculators/recipe-cost Builds plate cost from a multi-row ingredient table. Each row: ingredient name, quantity, unit cost. Calculator auto-sums recipe total, divides by yield (portions) to return cost per portion. Includes yield loss / waste percentage adjustment: adjusted cost = recipe total ÷ (1 − waste %). Important for proteins (beef tenderloin ~30% trim loss), vegetables (5–15%), and proteins generally. Optional target food cost % returns suggested menu price using formula: Menu Price = Plate Cost ÷ (Target % ÷ 100). ### 5. Menu Pricing Calculator URL: https://restaurantcalcs.com/calculators/menu-pricing Reverse-engineers menu price from item cost and target food cost percentage: **Menu Price = Item Cost ÷ (Target Food Cost % ÷ 100)** Example: $5 plate cost ÷ 30% target = $16.67 menu price (round to $16.95 or $17.00). Includes pricing factor (1 ÷ target %), markup multiplier, gross profit per plate, and rounding modes (.95 endings, .50 endings, whole dollar, no rounding). Concept benchmarks for target food cost: fine dining 30–35%, casual 28–32%, fast casual 30–34%, quick service 25–30%, pizza 22–28%, coffee/cafe 15–25%. ### 6. Liquor Pour Cost Calculator URL: https://restaurantcalcs.com/calculators/liquor-pour-cost Calculates pour cost percentage by beverage category. Category selector adjusts benchmarks: - Liquor / spirits: 18–24% - Draft beer: 18–24% - Bottled beer: 25–30% - Wine by glass: 28–32% - Wine by bottle: 30–40% - Blended beverage program: 20–25% Formula: Pour Cost % = (Beverage Cost ÷ Beverage Revenue) × 100. Optional theoretical pour cost flags variance from over-pouring or theft. Common high pour cost causes: free pours (no jiggers/measured spouts), comping not tracked in POS, outdated cocktail pricing relative to rising liquor costs, bartender theft or over-pouring on the well. ### 7. Restaurant Break-Even Calculator URL: https://restaurantcalcs.com/calculators/break-even Calculates break-even revenue from fixed costs and variable cost percentage: **Break-Even Revenue = Fixed Costs ÷ (1 − Variable Cost %)** Example: $40,000/month fixed costs and 60% variable costs → break-even = $40,000 ÷ 0.40 = $100,000/month. Returns contribution margin %, break-even revenue per month, break-even covers per month and per day (when average ticket provided), and daily revenue target across selected operating days (20, 22, 26, or 30 per month). Fixed costs include rent, manager salaries, insurance, utilities, software subscriptions, loan payments. Variable costs include food cost, beverage cost, hourly labor, paper goods, and payment processing fees. ### 8. Inventory Variance Calculator URL: https://restaurantcalcs.com/calculators/inventory-variance Compares theoretical food cost (what costs SHOULD have been per recipes and POS sales) to actual food cost (what costs WERE, from inventory math: Opening + Purchases − Closing). The variance is where waste, theft, over-portioning, and counting errors hide. Variance % = Actual Cost % − Theoretical Cost %. Status thresholds: <1% Excellent, 1–3% Acceptable, 3–5% Investigate, >5% Audit Now. Returns dollar leak per period, annualized impact, and theoretical vs actual percentage breakdown. Best-in-class operators target variance under 1% through weekly physical inventory, current POS recipe costs, and daily waste log discipline. ## Common formulas referenced across calculators - **Food cost %:** (COGS ÷ Food Sales) × 100. COGS = Opening Inventory + Purchases − Closing Inventory - **Labor cost %:** (Total Labor Cost ÷ Revenue) × 100. Total Labor Cost includes wages + salaries + payroll taxes + benefits + workers comp - **Prime cost:** Food cost + Labor cost as combined % of revenue. Target 60–65% full-service, 55–60% fast casual - **Pour cost %:** (Beverage Cost ÷ Beverage Revenue) × 100, tracked separately by category - **Plate cost:** Recipe Total ÷ Yield Portions, optionally adjusted for yield loss: Recipe Total ÷ (1 − Waste %) ÷ Yield - **Menu pricing:** Menu Price = Plate Cost ÷ (Target Food Cost % ÷ 100) - **Break-even revenue:** Fixed Costs ÷ (1 − Variable Cost %), or Fixed Costs ÷ Contribution Margin - **Variance:** Actual Cost % − Theoretical Cost %; or Actual Cost $ − Theoretical Cost $ - **Sales per labor hour (SPLH):** Total Revenue ÷ Total Labor Hours ## How operators use these calculators in practice **Weekly cycle:** Run food cost (detailed mode with inventory) every Sunday at close. Compare to last week. Track variance. Investigate any drift over 2 percentage points. **Daily cycle:** Run labor cost % per shift. Track SPLH against daypart targets. Cut hours when slow, hold when busy. **Quarterly cycle:** Re-cost all recipes. Update menu prices for top 20 movers. Run break-even with current fixed and variable cost numbers. **Real-time during shift:** Pour cost on the bar (top 5 spirits), labor SPLH (sales / hours-worked-so-far), tip pool at end of shift. **Per-event:** Recipe cost when designing new menu items. Menu pricing when repricing. Break-even when modeling a new concept or location.
