How do I calculate calories in a homemade recipe?

Enter each ingredient, its grams and calories per 100 g. The calculator totals the recipe and divides by servings.

Why does cooked weight matter?

Cooking changes water and sometimes fat content. The same calories spread over a smaller finished weight give more calories per 100 g.

Is this a full nutrition facts label?

No. This page focuses on calories and macros. It does not generate a regulatory label with micronutrients or daily values.

Should I use raw or cooked ingredient data?

Use the nutrition data that matches what you weighed. For mixed recipes, many people enter raw ingredient amounts and then enter the final cooked yield for per-100 g logging.

Calculate recipe calories from ingredients

Recipe calorie searches are usually about homemade food: add each ingredient, enter the amount used, divide the total by servings and optionally use the finished recipe weight for a per-100 g value.

C_{i} = \frac{m _{i}}{100} \cdot C_{100, i}

Ci - calories from one ingredient, mi - ingredient weight in grams, C100i - calories per 100 g.

C_{r ec i p e} = \sum C_{i}

Crecipe - total recipe calories.

C_{ser v in g} = \frac{C _{r ec i p e}}{N}

Cserving - calories per serving, N - number of servings.

C_{100} = \frac{C _{r ec i p e}}{m _{f ini s h e d}} \cdot 100

C100 - calories per 100 g finished recipe, mfinished - cooked yield or final weight.

Per serving vs per 100 g

Use per serving when the recipe is divided into equal meals or portions.
Use per 100 g when you weigh cooked food on a plate or log a variable serving size.
Cooking often changes water weight, so per-100 g values are better when you enter the actual cooked yield.
Oil left in a pan, drained liquid, marinades and trimming can change the real calories eaten.

Nutrition values are estimates. Branded foods, label rounding and cooked yield can differ from generic database values.
