Persimmons are a sweet, fiber-rich autumn fruit, but their vitamin C content varies widely depending on variety and ripeness. This calculator helps you estimate the vitamin C you get from a serving of persimmons, whether you're tracking micronutrients for general health, managing a specific diet, or just curious about your fruit intake.
Simply enter the weight of your persimmon (or use a quick preset), choose the variety and ripeness, and the tool will compute the vitamin C in milligrams, along with the percentage of your daily value (DV) based on the FDA's 90 mg reference. You'll also see a breakdown per 100 grams and per fruit, making it easy to compare with other foods.
Whether you're a dietitian, a fitness enthusiast, or someone planning meals, this tool turns raw nutrition data into a clear, actionable number. Use it alongside your favorite nutrition tracking app to fine-tune your vitamin C goals.

How to Use This Tool
Enter the weight of your persimmon in grams, ounces, or pounds, or click a quick preset like "1 medium (168 g)" to get started. Then select the variety — Japanese (Fuyu), American, or Black — and choose whether it's ripe or unripe. The calculator uses standard USDA nutrition data to estimate vitamin C content. Press Calculate to see your results, including the total milligrams, the percentage of the daily value (based on 90 mg), and a per-100-gram breakdown. Use the Reset button to clear all fields and start over.
How It Works
The calculator applies a simple proportion: vitamin C (mg) = (weight in grams ÷ 100) × vitamin C per 100 grams. The per-100-gram values come from the USDA FoodData Central database:
- Japanese persimmon (Fuyu): 7.5 mg per 100 g
- American persimmon: 66 mg per 100 g
- Black persimmon: 23 mg per 100 g
For unripe fruit, we apply a 20% reduction to account for lower vitamin C content, as vitamin C tends to increase as fruit ripens. The daily value (DV) is based on the FDA's reference of 90 mg per day for adults.
Worked Examples
Example 1: You eat one medium Japanese persimmon weighing 168 g. Vitamin C = (168 ÷ 100) × 7.5 = 12.6 mg. That's about 14% of your daily value.
Example 2: You have 100 g of American persimmon. Vitamin C = (100 ÷ 100) × 66 = 66 mg, which is 73% of the DV — a much richer source.
Example 3: A large black persimmon at 255 g, ripe: (255 ÷ 100) × 23 = 58.7 mg, or 65% of the DV.
Tips & Best Practices
- Weigh your persimmon with a kitchen scale for the most accurate result. If you don't have one, use the presets as a rough guide.
- Remember that vitamin C is water-soluble and sensitive to heat. Eating persimmons raw preserves the most vitamin C.
- Pair persimmons with other vitamin C-rich foods like citrus or bell peppers to easily meet your daily needs.
- If you're tracking for a specific diet, note that the DV is a general guideline; individual needs may vary.
Factors Affecting Accuracy
The vitamin C content of persimmons can vary due to growing conditions, storage time, and exact variety. The values used here are averages from USDA data. Unripe fruit may have lower vitamin C, and prolonged storage can also reduce levels. For the most precise tracking, consider using a nutrition database or app that reflects the specific product you're eating.
Frequently Asked Questions
Are persimmons a good source of vitamin C? It depends on the variety. American persimmons are excellent, providing over 70% of the DV per 100 g, while Japanese persimmons are moderate. Black persimmons fall in between.
Can I eat persimmons every day? Yes, in moderation. They're also high in fiber and antioxidants, but they contain natural sugars, so balance them with other fruits.
Does cooking affect vitamin C? Yes, heat can degrade vitamin C. Enjoy persimmons raw for maximum benefit.
How does this compare to other fruits? For reference, oranges have about 53 mg per 100 g. Use our persimmon calorie calculator to track calories too.
