Scale a recipe up or down by servings and see the total calories per serving — useful for meal prep and dinner parties.

Recipes are written for a specific number of servings, usually 4–6. When you cook for two, or for a dinner party of ten, the mental math gets annoying — especially if the recipe lists ingredients in mixed units. This calculator handles the arithmetic so you can focus on cooking.
It also shows total calories and per-serving calories. Most recipe sites quote calories per serving but base those numbers on the recipe writer portion size, not yours. By entering ingredients with calories per 100 g, you get accurate numbers for the portions you actually cook.
The output is honest — it scales linearly. Spices and aromatics often do not need to scale at the same rate (doubling a recipe rarely needs double the garlic). Treat the scaled amounts as a starting point and trust your tongue from there.
Because most recipe sites use generous serving sizes. Knowing the actual calories for your portion size makes weight management much easier.
Yes. The calculator handles fractional servings (1.5x, 0.75x). Pour what the scaled number says, or round to the nearest convenient amount.
No — it scales raw ingredient calories. Frying, boiling and steaming can change calorie density (more oil added, water lost), but those changes are usually small relative to portion size.
