Calorio / Free calorie counter

Free calorie counter for your portion

Start with the calories per 100 g on a food label and the amount you eat. This free calculator works without an account. For a mixed meal, Calorio also lets you build a preview from 371 USDA ingredients after signing in.

From a label to your portion

  1. Check the basis

    Use values per 100 g with grams, or per 100 ml with millilitres. Do not mix the two: 100 ml is not always 100 g.

  2. Measure your portion

    Weigh the amount you plan to eat. Multiply the label value by your portion and divide by 100. Repeat for protein, carbs and fat if needed.

  3. Build a whole meal

    Sign in to combine ingredients and preview the total. Match raw or cooked foods to what you weighed. Saving meals and logging your day require Premium.

Free calorie counter

Use matching units from the label. This calculates food energy, not your daily calorie target.

Calories in your portion: 200 kcal

AI: 3 scans in total per signed-in account; without an account, 1 scan per day per IP (UTC). Barcodes and manual entry use no AI credits. Anti-abuse limits apply: 100 combined requests per day with an account, 20 per IP without one.

Example: 250 g at 80 kcal per 100 g

80 × 250 ÷ 100 = 200 kcal. These are illustrative label values, not a claim about a particular product. Change either value in the calculator to work out your own portion.
