A whole mango contains roughly 150 calories, though the exact number depends on size. One cup of mango pieces (165g) has about 100 calories, making it a moderate-calorie fruit on par with bananas and grapes. Most of those calories come from natural sugars.
Calories by Serving Size
The standard reference for mango nutrition is one cup of fresh pieces, weighing about 165 grams. That serving delivers approximately 100 calories. Since a medium-sized whole mango yields roughly 1.5 cups of fruit once you remove the large flat seed and skin, you’re looking at around 150 calories for the entire fruit. A smaller mango closer to 200g total weight (fruit plus seed and skin) lands around 130 calories, while a large one can push past 170.
The six major commercial varieties sold in the U.S., including Ataulfo (sometimes called honey mango), Tommy Atkins, Kent, Keitt, Haden, and Francis, share essentially the same calorie profile. The National Mango Board lists a single nutritional breakdown across all varieties rather than distinguishing between them, so you don’t need to worry about picking a “lower calorie” type.
Carbs, Sugar, and Fiber
Nearly all of a mango’s calories come from carbohydrates. One cup of pieces contains 25 grams of total carbs, with 23 grams of that being natural sugars (mostly sucrose and fructose) and 3 grams from dietary fiber. Protein and fat are negligible, each under 1 gram per cup.
That 23 grams of sugar is higher than many fruits per serving. A cup of strawberries, for comparison, has about 7 grams. But the fiber content and the water-rich structure of fresh mango slow down how quickly that sugar hits your bloodstream. Mangoes score 51 to 56 on the glycemic index, which falls in the low-to-medium range, similar to orange juice. For most people, a cup of fresh mango won’t cause a dramatic blood sugar spike.
Dried Mango Is a Different Story
Drying removes water and concentrates everything. A quarter-cup of dried mango (about 40 grams, or 9 small pieces) packs 128 calories. That’s more calories in a much smaller volume than fresh mango, which makes it easy to eat far more than you planned. A full cup of dried mango can top 500 calories. If you’re tracking intake, weigh or measure dried mango rather than eating it straight from the bag.
Many commercial dried mango products also add sugar during processing, pushing the calorie count even higher. Check the ingredients list: the only ingredient should be mango if you want the closest match to the fresh fruit’s nutrition.
Vitamins and Antioxidants
Mangoes earn their reputation as a nutrient-dense fruit. A single whole mango provides about 122 mg of vitamin C, roughly 135% of the recommended daily amount. That’s more vitamin C than an orange. Mangoes are also one of the richest fruit sources of vitamin A (as beta-carotene), delivering around 25% of your daily needs per cup, which supports eye health and immune function.
Beyond the standard vitamins, mangoes contain a unique polyphenol compound with strong antioxidant and anti-inflammatory properties. This compound, found primarily in mangoes, has shown potential in animal studies for protecting brain cells and reducing markers of inflammation. The research is still in early stages, but it adds to the case that mangoes offer more than just vitamins.
How Mango Compares to Other Fruits
- Apple (1 medium): 95 calories, 19g sugar
- Banana (1 medium): 105 calories, 14g sugar
- Mango (1 cup pieces): 100 calories, 23g sugar
- Blueberries (1 cup): 85 calories, 15g sugar
- Grapes (1 cup): 104 calories, 23g sugar
Mango sits in the middle of the pack for calories but toward the higher end for sugar content per serving. If you’re watching sugar specifically, pairing mango with a protein or fat source (yogurt, nuts, cottage cheese) helps moderate the glycemic response and keeps you full longer.
Practical Portion Tips
A whole mango at 150 calories is a perfectly reasonable snack or addition to a meal. Where people run into trouble is with mango in smoothies, where it’s easy to blend two or three cups without noticing, or with dried mango, where the small volume disguises high calorie density. Frozen mango chunks, sold in most grocery stores, are nutritionally identical to fresh and make portion control easier since you can measure out exactly one cup.
For context, if you eat one cup of fresh mango as a daily snack, you’re adding about 700 calories per week, along with a full week’s worth of extra vitamin C and a meaningful amount of fiber. That’s a solid nutritional return for the calorie investment.
