A whole medium mango contains roughly 150 calories, with most of that energy coming from natural sugars. One cup of diced fresh mango (165 grams) has 99 calories, 24.8 grams of carbohydrates, and 22.6 grams of sugar, making it comparable to other tropical fruits like pineapple and papaya.
Calories by Portion Size
How many calories you get depends entirely on how much mango you eat, and mangoes vary quite a bit in size. A cup of diced mango (165 grams) is the standard reference serving at 99 calories. Since a medium mango yields roughly 1.5 cups of edible flesh once you remove the large flat pit and skin, you’re looking at about 150 calories for the whole fruit. A smaller mango closer to one cup of flesh lands right around 100 calories.
Per 100 grams, fresh mango runs about 60 calories. That’s a useful number if you’re weighing portions or comparing it to other fruits. For context, bananas have about 89 calories per 100 grams, apples around 52, and grapes about 67. Mango falls in the middle of the fruit calorie range.
Sugar and Carb Breakdown
Nearly all of mango’s calories come from carbohydrates, specifically sugars. A one-cup serving delivers about 22.6 grams of sugar and 2.6 grams of fiber. The sugar is a mix of sucrose, glucose, and fructose, all naturally occurring in the fruit.
Fresh mango has a moderate glycemic index of about 56, meaning it raises blood sugar more gradually than high-GI foods like white bread but faster than berries or cherries. The fiber content, while modest, helps slow digestion somewhat. If you’re managing blood sugar, pairing mango with a protein or fat source (yogurt, nuts) can blunt the glucose spike.
Calories Differ by Variety
Not all mangoes are created equal. Ataulfo mangoes (the small, golden ones sometimes labeled “honey mango”) contain about 78 calories per 100 grams, slightly higher than the average for larger varieties like Tommy Atkins or Kent. Ataulfo mangoes are also denser and creamier, so a whole one packs more calories per piece despite being physically smaller. The sugar profile differs too: Ataulfo mangoes have about 6.2 grams of sucrose, 1.8 grams of glucose, and 3.1 grams of fructose per 100 grams.
In practice, the calorie difference between varieties is small enough that it won’t matter for most people. Choose whichever variety tastes best to you.
Dried Mango Is a Different Story
Dried mango concentrates the sugars and calories dramatically. A quarter-cup serving (about 9 pieces, or 40 grams) contains 128 calories, 31 grams of carbohydrates, and 27 grams of sugar. That’s more calories in a small handful than in a full cup of fresh mango. The fiber also drops to just 1 gram per serving, so dried mango hits your bloodstream faster.
Many commercial dried mango products add sugar on top of what’s already there naturally, pushing the calorie count even higher. If you’re buying dried mango, check the ingredients list for added sweeteners. Unsweetened versions still pack a calorie punch compared to fresh, but at least you’re only getting the fruit’s own sugars.
How Mango Fits Into Your Diet
At roughly 100 calories per cup, fresh mango is a reasonable snack or addition to a meal. It provides vitamin C (one cup covers about 67% of your daily need), some vitamin A, and smaller amounts of folate and potassium. The calorie density is low enough that a serving won’t derail most eating plans, but the sugar content means it adds up quickly if you eat two or three cups at a time.
Frozen mango chunks have essentially the same calorie profile as fresh, since they’re just flash-frozen fruit. Mango juice, on the other hand, strips out the fiber and makes it easy to consume far more calories than you would eating the whole fruit. A cup of mango juice can run 130 to 140 calories, and you lose the satiety benefit that chewing and fiber provide.
