Persimmons are one of the more underrated autumn fruits: a single medium Fuyu packs a generous dose of fiber, vitamin A, and potassium with only about 118 calories. This nutrition calculator converts any serving size — grams, ounces, cups, or whole fruits — into a full nutrient breakdown, including calories, macronutrients, net carbs, and key micronutrients.
Whether you are tracking calories, planning a snack, or simply curious about how persimmons fit into your daily values, this tool gives you fast, consistent estimates based on USDA reference data for raw Japanese persimmon.
Just enter a quantity, choose a unit, and press Calculate. The results show macros, calories, net carbs, and optional percent Daily Values to help you compare a serving against a 2,000-calorie reference diet. You can also use the preset serving buttons to quickly test 100 g, a cup, or one whole fruit.

Step-by-Step Guide
This calculator is designed to be fast and flexible. Start by entering a quantity — a whole number for fruits or cups, or a decimal if you want a partial serving. Then pick the unit that matches what you are measuring. The preset buttons are handy for common servings like one medium fruit or 100 g.
- Enter a quantity in the first field.
- Choose a unit: grams, ounces, cups, or whole fruits.
- Optionally toggle Show % Daily Value to include DV percentages.
- Click Calculate Nutrition to see calories, macros, net carbs, and micronutrients.
- Use Copy Summary to copy a one-line nutrition summary to your clipboard.
If you only have a rough idea of size, choose medium fruit — most grocery-store persimmons weigh close to 168 g.
How the Nutrient Estimates Are Calculated
The tool uses USDA FoodData Central reference values for raw Japanese persimmon. For any serving, the nutrient amount is calculated as: nutrient per 100 g × (serving weight in grams ÷ 100). Calories are then estimated from protein, carbohydrate, and fat using the standard Atwater factors of 4, 4, and 9 kcal per gram.
Reference values per 100 g of raw Japanese persimmon: 70 kcal, 18.59 g carbohydrate, 3.6 g fiber, 12.53 g sugar, 0.58 g protein, 0.19 g fat, 161 mg potassium, 7.5 mg vitamin C, and 81 mcg RAE vitamin A.
Because persimmons can vary by variety, ripeness, and growing conditions, treat the results as a close estimate rather than a lab-tested value.
Portion Size Reference
Whole-fruit servings are based on typical weights used in nutrition databases. Your actual fruit may be a little larger or smaller, especially if it is an astringent Hachiya rather than a squat Fuyu.
| Portion | Approx. Weight |
|---|---|
| 1 small fruit | 100 g |
| 1 medium fruit | 168 g |
| 1 large fruit | 200 g |
| 1 cup sliced | 168 g |
| 1 ounce | 28.35 g |
Daily Values and Percent DV
The optional Percent Daily Value column uses FDA reference values for adults: 28 g fiber, 4,700 mg potassium, 90 mg vitamin C, and 900 mcg RAE vitamin A. Percent DV is a quick way to see how much a serving contributes to a daily reference diet, not a personal target. Your needs change with age, activity, medical conditions, and overall dietary pattern.
Worked example: one medium persimmon weighs 168 g, which is 1.68 × 100 g. Calories are about 1.68 × 70 = 118 kcal. Total carbs are about 1.68 × 18.59 = 31.2 g, fiber is 1.68 × 3.6 = 6.0 g, and net carbs are therefore about 25.2 g.
Frequently Asked Questions
Are Fuyu and Hachiya persimmons nutritionally the same?
Both are Japanese persimmons and have similar macro profiles, but Hachiya fruits tend to be larger and more astringent until fully ripe. The astringency is caused by tannins, not by significantly different calories or fiber. Use the medium or large fruit presets depending on which type you are eating.
Why do calorie counts from labels differ from this calculator?
Packaged persimmon products may be dried, peeled, or sweetened. Dried persimmons are far more calorie-dense than raw fruit because water is removed. This calculator is intended for fresh, raw persimmons only.
Do persimmons fit into a low-carb diet?
A medium persimmon contains about 25 g net carbs, so it is higher in carbs than berries but comparable to an apple. It can fit into a moderate low-carb plan if portion sizes are watched, but it is hard to fit into a strict keto macro target.
Is the fiber in persimmons mostly soluble?
Persimmons contain a mix of soluble and insoluble fiber. Soluble fiber helps slow digestion and supports blood sugar control, while insoluble fiber adds bulk. The 3.6 g of fiber per 100 g is a solid contribution toward the daily recommendation.
