Work out what each ingredient costs in your recipe, then see the total and cost per serving. Compare pack sizes without uploading your prices.
How to use Recipe cost calculator
- Enter one CSV row per ingredient, using the headers and unit codes in the example.
- Set the recipe servings, currency code and number of decimal places. Calculate and check the ingredient breakdown.
- Download complete JSON, the ingredient CSV or the recipe summary CSV.
Useful next steps
Pay for the amount you actually use
A 1 kg bag of flour costing 2.40 contributes 0.72 when you use 300 g. A 1 L carton costing 1.20 contributes 0.30 when you use 250 mL. Two eggs from a pack of twelve costing 3.60 add 0.60. The recipe costs 1.62 in total, or 0.41 per serving for four servings after rounding.
Keep your units compatible
Use kg, g, mg, lb or oz for mass; L, mL, US gallon, Imperial gallon or US fl oz for volume; and item for counts. US gallon and Imperial gallon are different measures. This calculator does not convert a volume of flour into its weight or guess ingredient density.
A clear rounding trail
Ingredient costs are added as exact fractions before the total is rounded. Rounded ingredient rows may differ from that total by a small amount. The displayed rounding adjustment reconciles them. The per-serving amount is calculated from the exact total, so multiplying rounded servings can also differ slightly.
