How the food cost calculator works
For each ingredient, choose how you know the price:
- Pack price — enter the pack size, what the pack cost, and how much you used. We charge only for the amount used, converting units automatically.
- Cost used — if you already know what the amount cost, type it in directly.
The total and cost per serving update as you type.
The formula
ingredient cost = pack price × (amount used ÷ pack size)cost per serving = total recipe cost ÷ servings
Example: you buy 1kg of flour for £2.00 but use 250g. The flour in your recipe costs £0.50, not £2.00.
Prices are yours
We don't pull live supermarket prices. Food prices vary by retailer, location, brand and date, so enter what you actually paid. Read the step-by-step recipe costing guide for more detail.
