Calories in Bananas
89 calories per 100g (100g)
A raw banana contains 89 calories per 100g, making it a moderate-calorie fruit that's naturally fat-free and packed with carbohydrates for quick energy. A typical medium banana (about 118g) delivers roughly 105 calories, while a large banana (136g) comes in around 121 calories. Most of those calories come from natural sugars and starch, with a small but useful boost of fiber and protein.

How does this compare?
Bananas are higher in calories than many fresh fruits in the Fruits and Fruit Juices category — strawberries provide about 32 calories per 100g and watermelon just 30 — largely because of their higher sugar and starch content. However, compared to dried fruits like dates (277 cal/100g) or raisins (299 cal/100g), bananas are a relatively low-calorie choice.

- 1.
Choose a smaller banana to trim calories — an extra small banana saves about 33 calories compared to a large one, with the same great nutrition profile.
- 2.
Pair a banana with a source of protein like Greek yogurt or nut butter to slow digestion, keep you fuller longer, and balance the natural sugar spike.
- 3.
Slice bananas into oatmeal or smoothies instead of eating a whole one separately — it makes the portion feel larger and helps stretch calorie budgets.
- 4.
Slightly underripe (greener) bananas contain more resistant starch, which acts more like fiber in the body and may have a gentler effect on blood sugar than fully ripe bananas.
- 5.
Freeze ripe banana slices and blend them solo for a one-ingredient 'nice cream' dessert — a 100g serving is still just 89 calories with no added sugars.
Common Questions About Calories in Bananas
How many calories are in a medium banana?
A medium banana measuring 7–8 inches and weighing approximately 118g contains about 105 calories, based on USDA data of 89 calories per 100g.
Are bananas high in calories compared to other fruits?
Bananas are moderate to high in calories relative to most fresh fruits. At 89 cal/100g, they have significantly more calories than berries or melon, but far fewer than dried fruits like raisins or dates.
How many calories are in a banana without the peel?
USDA calorie data for raw bananas already refers to the edible portion without the peel, so a 100g peeled banana is 89 calories. The peel typically accounts for about 35% of a whole banana's weight.
Do bananas have more calories when they are ripe?
The total calorie count doesn't change significantly as a banana ripens. What changes is the type of carbohydrate — starch converts to sugar — which affects taste and glycemic response, but not the overall calorie content.
