About this tool
Build any recipe from real ingredient data and see calories, protein, carbs, fat and fibre per serving.
Recipe Nutrition Estimator builds a nutrition label for a dish you enter yourself: pick ingredients from a built-in table of about 147 foods with per-100 g values for calories, protein, carbs, fat and fibre, enter the weight of each, set the number of servings, and it divides the totals to give per-serving figures. It also splits the calories by macro using the 4/4/9 kcal-per-gram convention, ranks which ingredient is contributing the most calories and what share, and shows each nutrient as a percentage of the FDA daily values (2000 kcal, 50 g protein, 275 g carbs, 78 g fat, 28 g fibre). It is an estimate from a reference table, not a lab analysis, and is intended for home cooks and anyone tracking intake rather than for regulatory labelling.
Open Recipe Nutrition Estimator on AltFTool — it loads instantly in your browser.
Set the Recipe name and Servings, then use "Add an ingredient" to search the 147-food table — each match shows its kcal / 100 g — and click one to add a row.
Type grams into each row, or tap the "Tap to add" chips (tsp, tbsp, katori, cup) which add that measure's real gram weight to the row.
Read the per-serving kcal, the "Where the calories come from" split at 4 kcal/g protein and carbs and 9 kcal/g fat, the %DV table and "What is making this heavy", then press "Copy nutrition label" or Save recipe.
Ingredients carry their own measure sets — tsp, tbsp, katori, cup — with real gram weights, so you can enter what you actually used.
Ingredients are ranked by calories contributed with a percentage share, and the top one comes with specific reduction swaps.
Totals, per-serving values, the macro split and %DV are all shown at once, and the whole label can be copied out as text.
They are estimates from a fixed per-100 g reference table, so expect to be in the right range rather than exact. Real variation comes from the fat content of your specific meat or dairy, how much oil the food absorbed, and water lost in cooking — none of which the table can see.
A 2000 kcal reference day with 50 g protein, 275 g carbohydrate, 78 g fat and 28 g fibre — the standard FDA daily values used on packaged labels. Your own requirement may be well above or below that depending on size, age and activity, so treat the percentages as a common yardstick rather than your personal target.
Protein and carbohydrate are counted at 4 kcal per gram and fat at 9 kcal per gram, then each is expressed as a share of that macro calorie total. Because alcohol and rounding are not accounted for, the split can differ slightly from the raw calorie figure.
Use it for general awareness only. It gives no sodium, sugar, cholesterol or micronutrient data, and the figures are estimates — if you are managing diabetes, kidney disease, an allergy or a clinically prescribed diet, work from values confirmed with a dietitian or your treating clinician.
