How many calories in chicken breast?
How many calories in chicken breast depends on whether you weigh it raw or cooked, whether the skin is included and whether you add cooking fat. This calculator keeps those choices visible so the meat figure stays honest.
Chicken loses roughly 25% of its weight as water during cooking. That means 100 g raw becomes about 75 g cooked: cooked chicken looks higher per 100 g because the water left, while the total calories in the piece barely change. Always log the state you weighed.
Grilling, baking, poaching and air-frying add nothing on their own. Olive oil and butter are shown separately when you add them; breaded and fried chicken is a different food and is not estimated here. A medium boneless skinless breast is roughly 170–200 g raw.
Cooked weight = raw weight × 0.75; raw weight = cooked weight ÷ 0.75 Values are based on USDA FoodData Central reference data for boneless skinless chicken breast and roasted chicken with skin. This tool is for food logging, not medical advice.
Chicken breast calorie calculator FAQ
Should I weigh chicken breast raw or cooked?
Either is fine, but choose the same state for the weight and nutrition entry. If you weigh raw chicken, use the raw result; if you weigh cooked chicken, use the cooked result. The conversion shows the matching weight in the other state.
Why are cooked chicken calories higher per 100 g?
Chicken loses roughly 25% of its weight as water during cooking. The calories become more concentrated by weight; the total calories in the piece barely change.
Does grilling or baking add calories?
The cooking method itself adds nothing in this calculator. Add olive oil or butter separately if you used it: one tablespoon is 119 kcal for olive oil or 102 kcal for butter.
Does chicken skin change the calories?
Yes. The cooked skin-on reference is 197 kcal, 30 g protein and 7.8 g fat per 100 g. The raw reference is the supplied boneless skinless value.
