Calories in feta
Calories, protein, carbohydrate and fat per 100 g and per serving, from the USDA reference database — plus what actually changes the number on your plate.
Short answer
100 g of feta contains 265 kcal, with 14.2 g of protein, 3.9 g of carbohydrate and 21.5 g of fat.
A typical serving — 1 cup, about 150 g — is roughly 398 kcal.
That is a fairly calorie-dense food, so portion size matters.

Where the calories come from
Calories come from three macronutrients: protein and carbohydrate at 4 kcal per gram, fat at 9 kcal per gram. For feta the split is:
- Protein: 14.2 g × 4 = 57 kcal — 21% of calories
- Carbohydrates: 3.9 g × 4 = 16 kcal — 6% of calories
- Fat: 21.5 g × 9 = 193 kcal — 73% of calories
- Most of the energy in feta comes from fat (73% of calories).
- It is high in sodium: 1,139 mg per 100 g.
- For 200 kcal you can eat about 75 g.
What actually changes the number
Feta is 265 kcal per 100 g, lower than most hard cheeses because it is brined and moist. Its strong flavour means a 30 g crumble (80 kcal) does the work of twice as much cheddar on a salad.
How accurate are these numbers?
The values on this page are reference averages from the USDA FoodData Central database (SR Legacy release), measured on samples of feta as sold and prepared in the United States. Your portion will differ: produce varies by variety and ripeness, meat by cut and trim, and anything cooked by the fat and water it gained or lost.
For most foods the per-100 g figure is reliable to within about 10%. The larger uncertainty is almost always the weight of what is on your plate and the cooking fat you cannot see — the two things worth checking before you worry about the database.

Can I track feta by taking a photo?
Yes. A photo calorie app like Wellix identifies feta on the plate and estimates the portion from the image. The estimate is most accurate when you confirm the weight or the count, and tell the app about anything the camera cannot see — cooking oil, butter, dressings and sauces.
