Recipe Nutrition Calculator

Calculate accurate nutrition facts for any recipe — free, and computed from the USDA FoodData Central database rather than an AI estimate. Every number links to its source.

Your FDA Nutrition Facts panel and per-serving breakdown will appear here — computed from USDA FoodData Central.

How the calculator works

1

Paste your recipe

One ingredient per line, with quantities — e.g. “2 cups flour”.

2

Set servings

Tell Mealary how many servings the recipe yields.

3

Get nutrition facts

Per-serving calories, macros, %DV, allergens and a label.

Mealary parses each ingredient line, converts household measures (cups, tablespoons, ounces) into grams using ingredient-specific densities, looks up the food in USDA FoodData Central, sums the nutrients, and divides by your serving count. The result is rounded per the FDA’s 21 CFR 101.9 rules so it matches a real Nutrition Facts panel.
