The formula is simple: cost per serving = total recipe cost ÷ number of servings.
A curry that costs £8.74 to make and serves 4 costs £2.19 per serving. Stretch it to 6 servings with extra rice and the cost per serving falls — though the total rises a little for the rice.
Make servings honest
- Count the portions you actually serve, not what the recipe card claims.
- Include sides (rice, bread, salad) in the total if they're part of the meal.
- Leftovers count as servings if they get eaten.
