Where does the nutrition data come from?

You enter the data yourself — values per 100g are found on food packaging or reputable food databases. The tool does no external lookups.

How is each nutrient calculated?

Each nutrient = (value per 100g) x (weight in grams) / 100. Values are summed across all ingredients.

What is the macro breakdown bar?

The bar shows the percentage of total calories contributed by protein (4 kcal/g), carbohydrates (4 kcal/g), and fat (9 kcal/g).

Can I save my recipe?

Not currently — this tool is session-only. Use your browser's print or screenshot function to save results.

What if I do not know the macros for an ingredient?

Check the food's packaging label or a free nutrition database such as the USDA FoodData Central website, then enter the per-100g values here.

Summary

Recipe Nutrition Calculator lets you build a recipe ingredient by ingredient, entering weight in grams and macros per 100g (calories, protein, carbs, fat). It computes totals and per-serving values and shows a visual macro breakdown bar — all in your browser, no account needed.

How it works

Enter each ingredient name, its weight in the recipe (grams), and the macronutrient values per 100g (calories, protein, carbs, fat).
The tool scales each nutrient by weight and sums the values across all ingredients to get the recipe total.
Set the number of servings to divide the totals into per-serving calories and macros.
Read the macro breakdown bar to see the share of calories from protein, carbs, and fat.
