Persimmons are often praised for their sweetness and vitamin A, but they also bring a small, useful amount of calcium to the table. This Persimmon Calcium Calculator converts any serving size — grams, ounces, or whole fruit — into milligrams of calcium and shows how much of your daily need it covers. Use it for meal planning, nutrition logging, or simply to see how this seasonal fruit fits your calcium goals.
Calcium content varies by variety and form. Japanese persimmons (including Fuyu and Hachiya) average about 8 mg of calcium per 100 g, while native American persimmons are richer, at around 27 mg per 100 g. The calculator lets you choose the variety and quantity, so you get an estimate that matches what is actually in your bowl. It also reports the percentage of the FDA Daily Value of 1,300 mg, which most adults can use as a practical benchmark.
No food label? No problem. Just select a unit and type in the amount, and the tool does the rest.
🥝 Calcium in Persimmons
Enter a serving size and choose the persimmon variety. The result updates with total calcium and its contribution to your daily value.
Why Calcium from Persimmons Matters
Calcium is usually associated with dairy, but many fruits contribute small amounts that add up over a varied diet. A single persimmon will not deliver a large calcium dose — a medium Japanese fruit contains only about 13 mg — but it can support your daily intake when paired with leafy greens, tofu, or fortified plant milks. For adults, the FDA Daily Value for calcium is 1,300 mg, so one persimmon covers around 1% of the day's target.
Persimmons also provide vitamin C, beta-carotene, and fiber, making them a useful part of an overall eating pattern. This calculator helps you see exactly where persimmons fit in your nutrient total.
How This Calculator Works
The tool uses the simple formula calcium = (weight in grams ÷ 100) × calcium per 100 g. If you enter ounces, it first converts using 1 oz = 28.3495 g. If you choose 'medium fruit' or 'large fruit,' it applies representative weights of 168 g and 216 g, based on typical raw Japanese persimmon sizes.
For example, 150 g of Japanese persimmon gives (150 ÷ 100) × 8 = 12 mg, about 0.9% of the DV. The same weight of native persimmon gives 40.5 mg, about 3.1% of the DV. If you track calcium in other foods, our popcorn calcium calculator offers a similar estimate for a snack you might eat by the handful.
Worked Examples
Using fresh Japanese persimmon (8 mg/100 g):
- 100 g — 8.0 mg calcium, 0.6% DV
- 1 medium fruit (168 g) — 13.4 mg, 1.0% DV
- 3.5 oz (99.2 g) — 7.9 mg, 0.6% DV
Using native American persimmon (27 mg/100 g), 100 g provides 27 mg (2.1% DV), and one medium fruit gives 45.4 mg (3.5% DV). Variety choice can change the result by more than threefold, so selecting the right preset matters.
Standard Calcium Values
| Form / variety | Calcium per 100 g | % DV per 100 g |
|---|---|---|
| Japanese persimmon (Fuyu, Hachiya), raw | 8 mg | 0.6% |
| Native American persimmon, raw | 27 mg | 2.1% |
| Dried persimmon (typical) | Variable | — |

Accuracy Notes & Best Practices
- Use a digital kitchen scale for the most reliable weight.
- Match the variety preset to the fruit you actually have: large orange Fuyu/Hachiya = Japanese; small wild fruit = native.
- For persimmon puree, weigh it if possible; 1 cup of puree tends to be about 200 g.
- Nutrient values are averages, not guarantees. Soil, ripeness, and storage can shift calcium by a few milligrams.
- If you are tracking calcium for medical reasons, review your whole diet with a doctor or registered dietitian.
Frequently Asked Questions
Are persimmons a good calcium source? Compared with milk (about 125 mg per 100 ml) or tofu, persimmons are low in calcium. But they still count, and every small contribution helps a varied diet.
Which variety should I choose? If you bought the common large, tomato-shaped fruit, use the Japanese value of 8 mg/100 g. If you have small wild American persimmons, use 27 mg/100 g. Japanese is the safe default for commercial fruit.
What about dried persimmons? Drying concentrates nutrients, but calcium values depend heavily on the brand and drying process. Use the nutrition label on the package rather than the fresh-fruit presets.
What Daily Value is used? The calculator uses the FDA's updated calcium Daily Value of 1,300 mg for adults and children aged 4 and older. You can find original nutrient data for persimmons in the USDA FoodData Central database. For another grain comparison, see our rice calcium calculator.
