Calories in ketchup
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 ketchup contains 101 kcal, with 1 g of protein, 27.4 g of carbohydrate and 0.1 g of fat.
A typical serving — 1 tablespoon, about 17 g — is roughly 17 kcal.

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 ketchup the split is:
- Protein: 1 g × 4 = 4 kcal — 4% of calories
- Carbohydrates: 27.4 g × 4 = 110 kcal — 96% of calories
- Fat: 0.1 g × 9 = 1 kcal — 1% of calories
- Most of the energy in ketchup comes from carbohydrate (96% of calories).
- 21.3 g of its carbohydrate per 100 g is sugar.
- It is high in sodium: 907 mg per 100 g.
- For 200 kcal you can eat about 200 g.
What actually changes the number
Ketchup is 101 kcal per 100 g and about 17 kcal per tablespoon — a quarter of it sugar. It is a small number that gets rounded to zero, which is fine unless you use it by the quarter-cup.
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 ketchup 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.

Frequently asked questions
How many calories are in 100 g of ketchup?
100 g of ketchup contains 101 kcal (1 g protein, 27.4 g carbohydrate, 0.1 g fat), according to USDA reference data.
How many calories are in a serving of ketchup?
A typical serving of ketchup — 1 tablespoon, about 17 g — has roughly 17 kcal. Weigh your own portion once to see how it compares; serving sizes vary more than the food does.
How much protein is in ketchup?
Ketchup: 1 g of protein per 100 g, which is low. Foods above about 15–20 g per 100 g, or where protein supplies a third or more of the calories, are usually considered high-protein.
What amount of ketchup equals 200 kcal?
At 101 kcal per 100 g, about 200 g of ketchup equals 200 kcal.
Can I track ketchup by taking a photo?
Yes. A photo calorie app like Wellix identifies ketchup 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.
