A whole medium mango contains roughly 150 calories, with most of that energy coming from natural sugars. One cup of sliced mango (about 165 grams) has around 107 calories, making it a moderate-calorie fruit, comparable to a banana but higher than berries or melon.
Calories by Serving Size
How many calories you get depends entirely on how much mango you eat, and portion sizes vary more than people realize. A small mango weighing around 200 grams (with the pit and skin removed, closer to 150 grams of flesh) lands near 100 calories. A large mango can weigh over 400 grams before peeling, delivering upward of 200 calories from the edible portion alone.
One cup of sliced raw mango provides about 107 calories and 3 grams of fiber. That’s the most practical number to remember, since most people eat mango cut into pieces rather than biting into a whole fruit. If you’re adding mango to a smoothie or fruit salad, a half-cup serving comes in around 50 to 55 calories.
What’s Actually in Those Calories
Mango is almost entirely carbohydrates. A one-cup serving has roughly 25 to 28 grams of carbs, the vast majority from natural sugars (fructose, glucose, and sucrose). Protein and fat are negligible, each under 1 gram per cup. The 3 grams of dietary fiber help slow digestion somewhat, but this is fundamentally a sugar-rich fruit.
Where mango stands out nutritionally is its vitamin content. A single cup delivers about 67% of your daily vitamin C, 10% of your daily vitamin A, and 18% of your daily folate. The vitamin A comes from beta-carotene, the same pigment that gives the flesh its deep orange color. You’d need to eat nearly two cups of pineapple to match the vitamin C in one cup of mango.
Ripe vs. Unripe Mango
The total calorie count doesn’t change dramatically between a green mango and a ripe one, but the type of carbohydrate inside shifts significantly. As a mango ripens, its starch converts into simple sugars like glucose, fructose, and sucrose. This is why a ripe mango tastes so much sweeter.
The practical difference shows up in how your body processes the fruit. Raw (unripe) mango has a glycemic index between 41 and 55, thanks to its higher starch and fiber content. Ripe mango sits at the upper end of that range, around 51 to 56, because the sugars digest more quickly and raise blood glucose faster. If you’re tracking blood sugar, eating mango slightly underripe or pairing it with a source of protein or fat can blunt that spike.
How Mango Compares to Other Fruits
Mango sits in the middle-to-upper range for fruit calories. Here’s how one cup of common fruits stacks up:
- Watermelon: about 46 calories
- Strawberries: about 49 calories
- Blueberries: about 84 calories
- Mango: about 107 calories
- Banana (one medium): about 105 calories
- Grapes: about 104 calories
- Cherries: about 97 calories
Mango is calorie-dense for a fruit mostly because of its sugar concentration. But unlike dried mango or mango juice (where calories climb fast and fiber disappears), fresh mango still provides water, fiber, and micronutrients that make those calories worthwhile.
Dried and Processed Mango
Dried mango is a calorie trap if you’re not paying attention. Removing the water concentrates the sugars into a much smaller volume, so a one-cup serving of dried mango can contain 300 to 500 calories depending on whether sugar has been added. Many commercial dried mango products also include added sugar or a sugar coating, pushing the count even higher. A quarter-cup of dried mango is a more realistic serving, coming in around 80 to 120 calories.
Mango juice and mango smoothie mixes follow the same pattern. Without the fiber from whole fruit, the sugars absorb faster, and it’s easy to drink two or three servings without realizing it. If you’re counting calories, fresh or frozen mango chunks are the best options, since they preserve the fiber and keep portion sizes honest.
