1. Calculate what you use, not what you buy
A 1 kg ingredient pack is not the cost of one recipe. If a pack costs 8 currency units and you use 250 g, the ingredient contribution is 2 units before any unavoidable trimming or spoilage. Keep the purchase quantity and recipe quantity in compatible units. A cup of flour cannot be converted accurately to grams without a density assumption, so weigh ingredients wherever precision matters.
2. Account for waste and yield
For an ingredient bought in bulk, the usable quantity may be smaller than the pack size. For example, with 90% edible yield, 250 g of usable ingredient represents approximately 277.78 g purchased. Track yield separately from the intended portion so your price does not quietly ignore waste.
3. Include labour, packaging and overhead
Add ingredient costs, prep time valued at a realistic hourly rate, packaging and a reasonable allocation of other costs. Costs that belong to the entire batch should be divided by the number of sellable portions. If the full batch costs 30 units and yields 10 portions, the unit cost is 3 units. The value of your own time counts even when you work alone.
4. Understand target margin versus markup
Margin measures profit as a share of selling price, while markup measures it against cost. Suppose your cost is 3 units per serving, you want a 25% margin and pay 5% platform fees calculated on the pre-tax selling price. The illustrative calculation is 3 ÷ (1 − 0.25 − 0.05) = 4.29 units before tax. Do not mistake that for a universal formula when fees include fixed charges or other bases.
5. Test the price before you publish a menu
Compare the calculated result against real orders, portion consistency, local competition and the customer experience. Check whether the tax you enter actually applies where you sell; the example above does not assume any local tax rate. Update the ingredient price every time a supplier price changes. A reliable costing process is more useful than an attractive spreadsheet that nobody maintains.
