About the Recipe Nutrition Calculator

List each ingredient with the grams used and its calories, protein, carbohydrate and fat per 100 g, then the number of servings. The calculator gives the totals and the amounts per serving.

Add each ingredient's nutrition scaled by the grams used, then divide by servings. Use values from food labels or USDA FoodData Central. Protein and carbohydrate supply about 4 kcal per gram and fat 9 kcal per gram (Atwater factors).

The formula

Nutrient = Σ grams × value per 100 g ÷ 100

Worked example

Porridge: 80 g oats, 250 g milk and 120 g banana, for 2

Recipe total: 563 kcal
Per serving: 281 kcal, 9.9 g protein, 46.8 g carbohydrate, 6.9 g fat

Things to keep in mind

Accuracy depends on the per-100 g values you enter; label values are rounded.

Questions people ask

Should I use raw or cooked weights?

Raw weights with raw-food values; cooking changes water, not calories.
