To calculate recipe cost, total each ingredient’s net cost and divide by yield for a clear cost per serving.
Knowing how to calculate recipe cost turns guesswork into a steady margin. You’ll price dishes with confidence, spot waste, and compare suppliers with real numbers. The steps below use simple math and repeatable checks you can run in any home kitchen, cottage business, or café line.
What You Need Before You Start
Pull a copy of your recipe with weights or volumes, current purchase prices, and any prep losses. Use grams or ounces for tight math. Keep one scale handy and one measuring set that lives with your costing sheet.
Core Fields To Track (Fast Reference)
This quick table shows the fields you’ll fill for each line item. It keeps everything tidy when you cost a new dish or refresh an old one.
| Ingredient | What To Record | Tip |
|---|---|---|
| Pack size | Weight or volume in the pack | Stick to one unit across the sheet |
| Pack price | Total price you pay after discounts | Use latest invoice, not memory |
| Unit cost | Pack price ÷ pack size | Convert to grams or ounces |
| Recipe quantity | Amount used in the recipe | Weigh trimmed, peeled, or drained |
| Edible yield % | Portion that ends up edible | Use tested yields for meat and veg |
| Net used | Recipe qty × edible yield | Adjust when peeling or cooking |
| Line cost | Unit cost × net used | Round to two decimals |
| Batch yield | Total cooked output | Weigh the finished batch |
Step-By-Step Recipe Costing (Worked Walkthrough)
1) Convert Everything To A Single Unit
Pick grams or ounces and convert every input. If a pack lists fluid ounces, convert to milliliters, then to grams with a tested density only when needed. Dry goods work well in grams. Liquids can stay in milliliters if every liquid follows that rule.
2) Find Unit Cost From Invoice
Unit cost equals pack price divided by pack size. If a can lists “net weight,” that excludes the package weight. When in doubt on tare and net checks, the methods in the NIST Handbook 133 give clear definitions and tests you can mirror for kitchen checks.
3) Apply Edible Yield
Trimming, peeling, and cooking change how much you truly use. Meat shrinks with heat; leafy greens wilt; canned beans drain. Use measured yields when you have them. For meats and poultry, USDA tables list shrink ranges by cut and method; they help set a fair edible yield until you build your own logs.
4) Calculate Each Line Cost
Net used equals recipe quantity times edible yield. Line cost equals unit cost times net used. Do this for every ingredient, then sum the lines for your batch cost.
5) Record Batch Yield And Portion Size
Weigh the cooked batch. Then pick a portion size that matches service. Cost per serving equals batch cost divided by the number of portions you plate from that batch.
How To Calculate Recipe Cost Step-By-Step (Worked Math)
Let’s say your chili uses 800 g beef, 400 g canned beans (drained), 500 g tomato, 40 g oil, and spices. Your batch yields 6 bowls at 350 g each. You pay 9.00 for 1 kg beef, 1.60 for a 450 g can of beans, 1.20 for 500 g tomato, and 3.60 for 500 g oil.
Trim And Shrink
Beef cooked yield set at 70%. Drained beans edible yield set at 90%. Tomato simmer loss set at 85% edible. Oil stays 100% because most remains in the food.
Math
Beef: unit cost 0.009/g; net used 560 g; line cost 5.04. Beans: unit cost 0.0036/g; net used 360 g; line cost 1.30. Tomato: unit cost 0.0024/g; net used 425 g; line cost 1.02. Oil: unit cost 0.0072/g; net used 40 g; line cost 0.29. Spices: flat 0.20. Batch cost 7.85. Portions 6. Cost per bowl 1.31. That’s the power of how to calculate recipe cost with clean inputs.
Ingredient Price Sources You Can Trust
Invoices matter, yet you need a yardstick when a vendor quote feels off. The Food Buying Guide lists yields and tools used by schools and agencies. For retail price levels across the country, the BLS page for average prices shows common foods. Use these as a check, then lean on your invoices for final math.
Common Pitfalls And Easy Fixes
Mixed Units
Teaspoons here, grams there, and cups in another row create messy sheets. Standardize one unit set and add a small cheat column for conversions.
Guessing Yields
Shrink varies by cut, pot size, and cook time. Run a quick test batch and write the loss. Keep a simple log so you improve with each round.
Ignoring Waste
Peels, bones, and trimmings change the true cost. Add a prep loss percent for items you trim.
Skipping Rounding Rules
Round unit costs and line costs to two decimals for menu talks. Keep raw math in the sheet for accuracy, then display rounded numbers to staff.
Calculating Recipe Cost Per Serving: Quick Math
Use this short set when you need a price today and a refined sheet later.
Fast Path
- Write the recipe with gram or ounce amounts.
- Add pack size and pack price for each item.
- Divide pack price by pack size to get unit cost.
- Apply a safe edible yield based on tests or a trusted table.
- Multiply unit cost by net used for each line.
- Sum line costs for batch cost.
- Weigh finished batch and divide by portion size for count.
- Divide batch cost by portion count for cost per serving.
Menu Price From Cost: Simple Paths
Pick a markup style and stay consistent within a menu group. Track food cost percent and a cash margin per plate. Menu price can come from either, then sanity-checked against local market.
Food Cost Percent
Menu price equals cost per serving divided by your target food cost percent. If your target is 30% and cost is 1.31, price starts at 4.37 before tax. Round to a clean number that fits your brand and rivals.
Contribution Margin
Pick a cash margin you need for the item. If you want 2.50 per bowl and your cost is 1.31, set price around 3.81 and adjust for tax and pattern across the menu.
How To Calculate Recipe Cost With Waste, Overhead, And Time
Raw ingredients are only part of the picture. You also spend on wrap, labels, gas, and labor. Add a small overhead line and a labor line so cost reflects the full plate.
Waste And Packaging
Add a light waste factor across the batch when your logs show plate returns or prep loss beyond the edible yield. Add containers, lids, labels, and napkins where takeout applies.
Labor
Track prep time for one batch. Labor cost per batch equals minutes worked divided by 60, times the fully loaded hourly rate. Add this to the batch cost before you set price.
Yield Sources And Quick Tests
When you lack your own data, use measured tables to set a starting yield, then test in your kitchen. USDA meat and poultry tables list cooked yield by cut and method. The Food Buying Guide has yield tables and a calculator that helps convert purchase units to ready-to-serve amounts.

Keep this compact worksheet near your scale. It nudges you through the same steps every time so your sheet stays clean and repeatable.
| Step | What To Do | Quick Formula |
|---|---|---|
| 1. Pick units | Use grams or ounces for all lines | — |
| 2. Unit cost | Pack price ÷ pack size | UC = PP ÷ PS |
| 3. Edible yield | Apply shrink/trim percent | EY = Qty × Yield% |
| 4. Line cost | Unit cost × net used | LC = UC × Net |
| 5. Batch cost | Sum of all line costs | BC = ΣLC |
| 6. Portion count | Batch weight ÷ portion size | PC = BW ÷ PS |
| 7. Cost per serving | Batch cost ÷ portion count | CPS = BC ÷ PC |
| 8. Menu price | Use food cost % or margin | MP = CPS ÷ % |
Audit And Update Rhythm
Set a reminder to refresh prices and yields. Meat prices swing with seasons; produce shifts with region. A monthly review for busy items and a quarterly pass for slow sellers keeps your costs honest.
Tools That Save Time
A simple spreadsheet gets you far. Add data validation for units, locked formulas for unit cost and line cost, and tabs for each menu section. If you run school meals or large volume, the Food Buying Guide tools and the Recipe Analysis Workbook speed up unit conversions and yield math.
FAQ-Free Wrap: What To Do Next
You can start today with one recipe you sell a lot. Build the sheet, weigh one fresh batch, and log yields. Share the cost per serving with your team, set a fair price, and watch how small waste cuts protect your margin. That’s the heart of how to calculate recipe cost for any kitchen that cares about steady numbers.
