How Many Calories Are in a Banana? A Quick Guide

Ever peeled a banana and wondered, “How many calories did I just eat?” Whether you’re tracking macros, aiming for weight loss, or just curious, here’s what you need to know no fancy calculator required!

Banana Calories by Size

Extra Small ~81 g ~72 kcal
Small ~101 g ~90 kcal
Medium ~118 g ~105 kcal
Large ~136 g ~121 kcal
Extra Large ~152 g ~135 kcal

Pro Tip: As bananas ripen, starch turns to sugar, adding a few extra calories.

Why Bananas Rock Beyond Calories

A medium banana (~105 kcal) also provides:

  • Carbs: 27 g (14 g natural sugar)
  • Fiber: 3 g
  • Potassium: 422 mg (12% DV)
  • Vitamin B6: 20% DV
  • Vitamin C: 17% DV

They’re a smart snack for quick energy, workout fuel, and gut-friendly fiber.
