Mangoes are one of the sweetest fruits in the produce aisle, and their carbohydrate content is something many keto, low-carb and diabetic meal planners track closely. A 100g serving of raw mango contains about 15g of carbohydrates, including roughly 13.7g of natural sugar and 1.6g of fiber. This free mango carbs per 100g calculator converts any portion — grams, ounces, cups, or whole fruit — into total carbs, net carbs, sugar and fiber, so you can log your mango accurately without manually working through nutrition labels.
Whether you're measuring a single slice for a snack, a full cup in a smoothie, or comparing dried mango slices to fresh, the tool uses standard USDA reference values and gives you a clear breakdown. Use it alongside your favorite calorie tracking app or use it to plan portions around your daily carbohydrate target.
🥭 Mango Carb Calculator
Calculate total carbs, net carbs, sugar, and fiber for any mango portion.
How to Use This Tool
Start by entering the amount of mango you plan to eat in the number field, then choose the matching unit from the dropdown. If you're using a recipe or food scale, grams or ounces are easiest; if you're estimating, use the quick portions for a standard half-cup, one cup, or a whole fruit. Select the form of mango from the menu — raw ripe, frozen, dried, or green — because drying concentrates carbohydrates dramatically, while green mango has a lower sugar profile. Press 'Calculate carbs' and you'll immediately see total carbs, net carbs, sugar, and fiber for your portion.
The tool also shows the conversion to grams and the calculation step, so you can verify the math and transfer the number to whatever tracking app you use. Use it before meals, when building a fruit salad, or when comparing a fresh mango slice to a handful of dried mango. If you track net carbs for keto or low-carb plans, the net-carbs result is the value most commonly subtracted from your daily allowance.
How It Works
The calculator uses USDA FoodData Central reference values for raw mango, plus commonly cited figures for frozen, dried, and green mango. For raw ripe mango, the reference values are approximately 14.98 g total carbohydrates, 13.66 g sugar, 1.6 g fiber, and 60 kcal per 100 g.
To calculate your portion, the tool first converts your chosen unit into grams using these standard weights: 1 cup of mango pieces weighs about 165 g, and one average whole mango with skin and pit removed yields about 336 g of edible flesh. It then applies the formula: total carbs = portion weight in grams × carbs per 100 g ÷ 100.
Net carbs are calculated by subtracting fiber from total carbs, since fiber is not fully digested and is often excluded on low-carb plans. Sugar and fiber are scaled the same way. These are averages, not exact constants — a mango's sugar content rises as it ripens, and specific cultivars like Ataulfo or Alphonso can differ by a gram or two per 100 g.
Worked Examples
Example 1: One cup of fresh mango
Enter 1 in the amount field and choose 'cups (pieces)'. The tool converts to 165 g. Using raw mango values: total carbs = 165 × 14.98 ÷ 100 = 24.7 g, net carbs = 24.7 − 2.6 = 22.1 g, sugar = 165 × 13.66 ÷ 100 = 22.5 g, fiber = 2.6 g.
Example 2: 50 g of dried mango
Dried mango contains roughly 78.6 g carbs per 100 g, so 50 g gives total carbs = 50 × 78.6 ÷ 100 = 39.3 g, net carbs = 39.3 − 1.2 = 38.1 g. Dried mango is much more carb-dense than fresh, so portion control matters.
Example 3: Half a whole fruit
A half fruit edible portion is about 168 g. Total carbs = 168 × 14.98 ÷ 100 = 25.2 g, net carbs = 25.2 − 2.7 = 22.5 g.
Tips & Best Practices
- Weigh mango flesh without skin or pit. The tool's 'whole fruit' preset already assumes skin and pit are removed, so don't double-subtract.
- If your mango is very ripe, expect sugar to be closer to the higher end; firmer mangoes are slightly lower in sugar and sometimes a bit higher in starch.
- For smoothies, remember that the mango carbs in a cup of smoothie will also depend on the other ingredients — check the total volume, not just the fruit pieces.
- Dried mango is often sweetened or coated with sugar, which can push the carb number even higher than the 78.6 g reference. Check the package label when available.
- Use net carbs only if your dietary plan specifically subtracts fiber. Traditional calorie counting and most diabetic exchanges still count total carbohydrates.
- Track portions consistently: it's better to slightly overestimate than underestimate when logging mango, especially if you're on a strict carb budget.

| Mango form | Total carbs (g) | Sugar (g) | Fiber (g) | Net carbs (g) |
|---|---|---|---|---|
| Raw ripe mango | 14.98 | 13.66 | 1.6 | 13.4 |
| Frozen mango | 14.7 | 13.4 | 1.6 | 13.1 |
| Dried mango (sweetened) | 78.6 | 66.9 | 2.4 | 76.2 |
| Green/unripe mango | 17.0 | 9.0 | 1.8 | 15.2 |
These figures are useful for meal planning, but individual fruit scales and cultivars vary. The USDA FoodData Central entry for raw mango (FDC ID 169910) is the primary source for the raw values; you can look up exact numbers at fdc.nal.usda.gov.
Frequently Asked Questions
How many carbs are in 100 g of raw mango? Raw ripe mango contains about 14.98 g of total carbohydrates per 100 g, of which about 13.66 g are sugars and 1.6 g is fiber. Net carbs are about 13.4 g.
Is mango high in carbs compared to other fruits? Yes, mango is on the higher end for tropical fruits, though not as concentrated as bananas (about 23 g/100 g) or dried dates (about 75 g/100 g). If you compare carb counts across fruit, you may find the kiwi carbs per 100g calculator or the vegetable carbs per 100g calculator useful for side-by-side tracking.
Can I eat mango on a low-carb diet? You can, but portions matter. A 100 g serving (roughly two-thirds of a cup) provides about 13 g net carbs, which can fit into a moderate low-carb allowance. On keto, where daily net carbs are usually 20–50 g, a small portion may be all you can spare.
Why does dried mango have so many more carbs? Drying removes water, concentrating the natural sugars into a smaller volume. A 100 g portion of dried mango contains almost five times the carbohydrates of fresh raw mango. Many commercial dried mango products are also coated with cane sugar.
Are the values the same for every mango variety? No. Varieties such as Ataulfo, Kent, and Tommy Atkins differ slightly in sweetness and fiber content. The calculator uses averaged USDA reference values, so treat the output as a solid estimate rather than an exact lab value.
