Food & Cooking Calculator

Calorie Counter by Food

Estimate calories for common foods by weight, serving size or quantity. Useful for quick meal checks, portion planning and linking food choices to your wider calorie goals.

Estimate calories by food

Choose a food, enter the amount you are eating, and the calculator will estimate the calories for that portion.

Pick the closest category.
Values are practical estimates, not exact brand data.
Use the option that matches your food label or kitchen measure.
Example: 100g, 2 slices or 250ml.
Useful for 2 bowls, 3 slices or multiple portions.
Food calories are normally estimates anyway.

How the calorie counter works

The calculator uses a simple calorie-per-100g, calorie-per-100ml or calorie-per-serving estimate, depending on the food selected and the measurement option you choose.

calories = calories per 100g × grams ÷ 100 calories = calories per 100ml × ml ÷ 100 calories = calories per serving × servings

For packaged food, the label is normally the best source because brands can vary. For homemade food, ingredients, oil, sauce and portion size can change the final calorie count.

Example calorie estimates

Cooked rice: 100g at about 130 kcal per 100g gives about 130 kcal.
Milk: 250ml semi-skimmed milk at about 50 kcal per 100ml gives about 125 kcal.
Bread: 2 slices at about 95 kcal per slice gives about 190 kcal.

Common food examples

These are broad planning values. The calorie count on a food label or recipe app may be different.

FoodTypical measureApproximate calories
Cooked rice100g130 kcal
Cooked pasta100g155 kcal
Chicken breast, cooked100g165 kcal
Banana1 medium105 kcal
Semi-skimmed milk100ml50 kcal
Cheddar cheese100g400 kcal

Why portion size matters

A small change in portion size can make a big difference to the result. For example, 75g of cooked rice and 250g of cooked rice are very different portions, even though they are the same food.

For weight-based foods, kitchen scales usually give a more reliable estimate than guessing by bowl, cup or handful.

FAQs

Is this calorie counter exact?

No. It gives a practical estimate. Food labels, restaurant recipes, cooking methods and portion sizes can all change the real number.

Should I use grams or servings?

Use grams where possible because it is usually more precise. Use servings or items when you only have label-style information, such as one slice, one bar or one pot.

Can I use this for a diet plan?

You can use it for general planning, but it is not medical advice. For personal health, medical or dietetic guidance, speak to a qualified professional.
