Banana calories & nutrition facts
A banana portion can be a whole fruit, slices on oats, or mashed fruit in a bake. Use the edible weight or a matching reference size to estimate the amount you add.
How many calories are in a medium banana?
One medium raw banana, without the peel (118 g) contains about 105 calories and 1.3 g protein. This uses the reference weight, so weigh your portion if its size differs.
For comparison, 100 g of this food contains 89 calories and 1.1 g protein. Adjust the amount below for your serving.

Slices and mash can fill a cup differently. The listed household measures are references; use grams when measuring a partial fruit or a recipe amount.

Values are scaled from the USDA figures per 100 g. Calories are rounded to a whole number; gram values to one decimal. A dash means the source does not provide that value. Portions are reference measurements, not serving recommendations.
Peel first when using grams.
The nutrition estimate is for the edible banana, not the peel. Small, medium, and large fruit labels are reference sizes; the banana on your counter may fall between them. Weighing the peeled fruit gives you a straightforward amount for the calculator, particularly when you use only part of it.
For banana bread or muffins, record the peeled banana weight used in the whole recipe alongside the flour, eggs, butter, and other ingredients. For a breakfast bowl or smoothie, add the yogurt, oats, milk, and toppings separately. Dried banana, banana chips, and sweetened banana products are different foods, so these figures should not be applied to them by weight.
Chocolate banana brownies: The recipe uses a cup of mashed banana. Use the mashed-cup portion in the table or weigh the peeled fruit, and include the other brownie ingredients separately.
