Calories in common servings
These are reference edible weights. Weigh your own food for a more precise result.
| Serving | Weight | State | Kcal | Protein | Fat | Carbs |
|---|---|---|---|---|---|---|
| Medium tomato without stem | 123 g | Red ripe tomato, raw | 22.14 | 1.08 g | 0.25 g | 4.78 g |
| 1 cherry tomato | 17 g | Red ripe tomato, raw | 3.06 | 0.15 g | 0.03 g | 0.66 g |
| 1 cup chopped or sliced tomatoes | 180 g | Red ripe tomato, raw | 32.4 | 1.58 g | 0.36 g | 7 g |
What affects the calorie value
The calculation covers a fresh ripe red tomato without dressing. Oil, cheese, sour cream and other salad ingredients can contribute more calories than the vegetables.
Cherry and plum tomatoes vary in size, so calculating their combined weight is easier. An average record works for everyday estimates but does not replace a specific package label.
Vitamins and minerals per 100 g
Values come from the same USDA records. They show the amount in the food, not a percentage of an individual daily requirement.
| Nutrient | Red ripe tomato, raw |
|---|---|
| Vitamin C, mg | 13.7 |
| Potassium, mg | 237 |
| Folate, µg | 15 |
| Vitamin A, RAE, µg | 42 |
| Vitamin K, µg | 7.9 |
| Manganese, mg | 0.11 |
How to calculate more accurately
Weigh the part you will eat, excluding the stem and discarded parts.
For a salad, combine the weight of the tomatoes and count oil, sour cream or cheese separately.
Tomato paste and dried tomatoes contain less water. They need a different record; raw tomato values will give an inaccurate estimate.
Common questions
Can I use this for cherry tomatoes?
This is an average raw red tomato record, not an analysis of a specific cherry variety. Use the label for a packaged product when available.
How many calories are in one medium tomato?
A 123 g medium tomato provides about 22 kcal using the selected reference record.
How many calories are in one cherry tomato?
As a guide, a 17 g cherry tomato contains about 3 kcal. Weighing the full serving is more practical.
Can I use this record for tomato paste?
No. Tomato paste contains much less water, so calories and nutrients per 100 g differ from fresh tomato.
