Cherry tomatoes get treated like a free food, since calories in cherry tomatoes are assumed to barely count. A person will eat a whole pint standing at the counter without a second thought.
That instinct is not far off. Still, a pint eaten mindlessly adds up to a real number. It is worth knowing what that number actually is.
Calories in cherry tomatoes per tomato, cup, and pint
USDA nutrition data puts a standard raw tomato at 22 calories per 123 grams. That figure comes from the USDA backed seasonal produce nutrition panel.
Do the math and that works out to roughly 0.18 calories per gram. A cup of cherry tomatoes weighs about 149 grams under USDA’s own reference measure for the fruit.
Scaling from that calorie density gives roughly 27 calories per cup. A single cherry tomato averages somewhere around 17 grams, so one fruit lands close to 3 calories.
A pint holds about two cups. That puts a full pint of cherry tomatoes at roughly 50 to 55 calories.
A handful, meaning what fits in a cupped palm, usually holds 8 to 12 tomatoes. That lands in the 25 to 35 calorie range, depending on fruit size that day.
Those are the numbers worth remembering. Calories in cherry tomatoes stay low across every common serving size, from a single fruit up through a full pint, and none of them come close to even a tenth of an average adult’s daily calorie budget.
How those numbers are actually calculated
There is no single USDA entry that lists calories for a cup of raw cherry tomatoes on its own. The figures above come from combining two real numbers, not from guessing.
The first number is the calorie density of a standard raw tomato. The second is the standard reference weight for a cup of cherry tomatoes specifically.
Multiply one by the other and the estimate holds up well against common rounded figures people already use. It is close to what most nutrition labels and apps show for the same serving.
Fruit size still shifts the exact number a little either way. A larger cherry variety or a tiny currant type will land slightly outside this range, but not by much.
None of this changes the basic picture. A snack of cherry tomatoes is one of the lowest calorie choices in the produce aisle by almost any measure.
That holds true whether the fruit comes from a store shelf or a backyard vine. The math does not care where the tomato was grown.
Why the calorie count stays so small
Tomatoes are mostly water. That single fact does most of the work in keeping calories low across every serving size.
What is left after the water is mostly natural sugar and fiber, plus a small amount of protein. None of those show up in large quantities per fruit.
The total stays under 30 calories a cup even with the sugar included. Cherry varieties often taste sweeter than a large slicing tomato, and that throws people off.
The extra sweetness comes from a slightly higher sugar to water ratio in a smaller fruit. It is not from more total sugar packed into each bite.
A cherry tomato simply concentrates the same sugar into less water per bite. The overall sugar content per fruit stays small either way.
Cherry tomatoes against a standard slicing tomato
Gram for gram, a cherry tomato and a large slicing tomato carry almost identical calorie density. The difference in total calories per fruit mostly comes down to size.
One large slicing tomato can weigh five or six times what a single cherry tomato weighs. Eat the whole slicer and the calorie count naturally climbs with it.
That makes portion count a poor way to compare the two types. Weight, or a measured cup, is the fairer comparison every time.
How cherry tomatoes compare to grape tomatoes
Grape tomatoes are shaped differently but land in a similar calorie range per gram. Fruit size and water content matter more than the cherry versus grape distinction.
Anyone deciding between the two for a snack can read the site’s full breakdown of how cherry tomatoes stack up against grape tomatoes. Flavor and texture, not calories, are the real differences worth weighing.
The calorie gap between them is small. Taste should decide the pick, not the number on a label.
Does how you eat them change the count
Raw, straight off the vine, a serving of cherry tomatoes stays close to the numbers above. Roasting or sauteing changes very little about the tomato itself.
Heat does not add calories on its own. What changes the math is anything added alongside the tomatoes.
A drizzle of olive oil before roasting can double or triple the calories of the dish. The tomatoes themselves contribute almost none of that increase.
The same goes for a bowl tossed with a heavy dressing. A handful eaten alongside a high calorie dip works the same way.
The tomato itself is rarely the actual problem in either case. It is nearly always what rides along with it.
Cherry tomatoes against other common snacks
A cup of cherry tomatoes at roughly 27 calories sits well below a cup of most crackers or chips. Those commonly run 400 to 500 calories per cup by volume.
Even a cup of grapes, a fruit people consider light, runs closer to 100 calories. That gap is a large part of why cherry tomatoes show up so often on snack lists.
Volume for volume, few whole foods deliver as little energy while still feeling like a real snack. Water content and fiber both help with that feeling of fullness.
A pint eaten as an afternoon snack runs roughly 50 to 55 calories. That costs less than a single granola bar in most cases.
Portion size becomes a matter of appetite, not calorie math, for most people who reach for a pint.
What else a serving brings besides calories
Cherry tomatoes are not just a low calorie filler food. Tomatoes are counted among common food sources of vitamin C, according to the NIH Office of Dietary Supplements.
The site covers that full nutrient picture in its full rundown of tomato vitamins and minerals. Vitamin content and daily value context both live there in more depth than fits here.
Potassium gets its own detailed page for anyone tracking that mineral specifically. The site’s guide to potassium in tomatoes breaks amounts down across fresh and cooked forms.
Cherry tomatoes contribute to that total the same way a standard slicing tomato does. It simply scales down with the smaller serving size of each fruit.
Portioning cherry tomatoes without guessing
A pint container from a grocery store or farm stand is the easiest reference point most people already have. It runs around 50 to 55 calories, which makes planning easy.
No scale or app is needed for a quick snack decision. The container itself does most of the work.
For anyone growing their own, yields vary a lot by variety and plant health. The site has tips for growing your own cherry tomatoes for readers chasing a bigger harvest.
A bigger harvest tends to matter more than a calorie count once the plants get going. A heavy home harvest also raises the freezing question fast.
Freezing a cherry tomato harvest keeps the fruit usable through winter. It does not change this same basic math once the fruit is thawed.
Cherry tomatoes measured by weight instead of volume
Cups and pints are convenient, but they are not exact. Two people filling the same measuring cup with different sized fruit end up with different actual weights.
Weighing solves that problem. A kitchen scale gives a more precise number than eyeballing a cup ever will, at roughly 18 calories per 100 grams.
That per 100 gram figure is the same calorie density used to calculate the per cup and per pint numbers above. It works well for anyone logging food in grams.
A small kitchen scale removes the guesswork entirely. It also makes it easy to track a home harvest the same way a store bought pint gets tracked.
What happens to the calorie count when they are cooked down
Cooking cherry tomatoes into a sauce or a roasted side dish does not add calories to the tomato itself. It does concentrate them.
Simmering drives off water, which shrinks the volume. The total calories stay roughly the same throughout.
A cup of raw cherry tomatoes cooked down to half a cup effectively doubles the calories per cup. Nothing was added to make that happen, only water was removed.
That is simple water loss, not a nutrition change. It matters mainly for anyone comparing a raw serving to a cooked one and expecting the numbers to match exactly.
Oil, butter, or sugar added during cooking is a separate factor entirely. Those additions affect the total far more than the water loss from the tomatoes ever does.
Frequently asked questions
How many calories in cherry tomatoes are in one cup?
A cup of cherry tomatoes runs about 27 calories. That is based on USDA’s reference weight of roughly 149 grams for a cup of the fruit, and it holds steady across red, orange, and yellow varieties.
How many calories are in a pint of cherry tomatoes?
A standard pint holds about two cups of cherry tomatoes, which puts the total near 50 to 55 calories. Most grocery store pint containers fall close to that range.
Are cherry tomatoes lower in calories than regular tomatoes?
Gram for gram, cherry tomatoes and standard slicing tomatoes carry very similar calorie counts. The difference in total calories per fruit mostly comes down to size, not variety.
Do cherry tomatoes have more calories than grape tomatoes?
The two are close enough that the difference rarely matters in practice. Fruit size within either type affects total calories per serving more than the cherry versus grape distinction does.
Can eating a lot of cherry tomatoes still affect calorie intake?
Yes, though it usually takes a large amount to matter. Several pints in one sitting add up fast, and a heavy dressing adds up even faster.
