Papaya is a tropical favorite with a bright, sweet flavor — but it isn't naturally high in iron. A 100-gram serving of raw papaya provides only about 0.25 mg of iron, less than 2% of the standard 18 mg Daily Value. This calculator converts any papaya serving into its estimated iron content, percentage of your daily iron target, vitamin C, and calories.
The vitamin C figure matters: papaya delivers roughly 61 mg of vitamin C per 100 g. Vitamin C helps your body absorb non-heme iron from plant foods, so papaya can be a useful companion to beans, lentils, tofu, and leafy greens.

How to Use This Tool
This calculator gives a quick, practical estimate of the iron in a papaya serving. Start by choosing a serving size from the quick-fill buttons, or type a custom number into the amount field and select the matching unit. The unit options include grams, ounces, cups of chopped papaya, and whole-fruit sizes (small, medium, and large).
- Enter the amount of papaya you plan to eat.
- Select the unit that matches your serving.
- Choose a daily iron reference that fits your life stage or goal.
- Press Calculate iron to see iron, %DV, vitamin C, weight, and calories.
Iron Content of Papaya: Reference Table
The values below represent raw, fresh papaya and come from standard USDA nutrient data. Iron in papaya is modest compared with animal foods or fortified grains, but the fruit still earns a place in a balanced diet because of its vitamin C, fiber, and hydration.
| Serving | Weight | Iron | Vitamin C | Calories |
|---|---|---|---|---|
| 100 grams | 100 g | 0.25 mg | 60.9 mg | 43 kcal |
| 1 cup, chopped | 145 g | 0.36 mg | 88.3 mg | 62 kcal |
| 1 small fruit | 152 g | 0.38 mg | 92.6 mg | 65 kcal |
| 1 medium fruit | 304 g | 0.76 mg | 185.1 mg | 131 kcal |
These are rough averages. Actual values shift with variety, ripeness, soil, and growing conditions.
📊 The Math Behind the Calculation
The calculator uses three simple conversions. First, it converts your chosen unit to grams with these reference weights: 1 ounce equals 28.35 g, 1 US cup of chopped papaya equals 145 g, one small papaya equals 152 g, one medium papaya equals 304 g, and one large papaya equals 609 g.
Next, it applies the nutrient density per 100 grams of raw papaya:
- Iron: 0.25 mg per 100 g
- Vitamin C: 60.9 mg per 100 g
- Calories: 43 kcal per 100 g
For each nutrient, the equation is the same: (grams ÷ 100) × nutrient value per 100 g. The percentage is then calculated by dividing the iron result by your selected reference intake and multiplying by 100.
What This Means for Your Diet
Papaya is not going to single-handedly cover your iron needs. A full medium fruit supplies only about 0.76 mg, which is a small fraction of the 8–27 mg recommended for different groups. Instead, papaya shines as a nutrient booster. Its vitamin C content can enhance the absorption of non-heme iron from plant-based meals. Non-heme iron is the type found in beans, lentils, spinach, tofu, and fortified cereals, and your body absorbs it less efficiently than the heme iron from meat.
Try pairing papaya with iron-rich foods: add chopped papaya to a lentil curry, blend it into a smoothie with spinach and oats, or eat it as dessert after a bean-based chili. Because vitamin C works best when consumed in the same meal, papaya can be a delicious way to get more value from the plant iron you already eat.

Accuracy & Limitations
This tool gives a useful estimate, not a laboratory measurement. Several factors can make the real iron content differ from the number shown.
- Variety and ripeness: A more ripe papaya may have slightly different water and nutrient content than a firmer one.
- Edible portion: The calculator assumes peeled, seeded, raw papaya. If you include skin or seeds, weights and nutrients change.
- Reference intakes: Daily values are population averages. Your personal iron needs depend on age, sex, pregnancy, medical conditions, and dietary patterns.
- Absorption: The percent DV is a comparison to a daily reference, not the amount your body actually absorbs. Iron absorption from plant foods depends on many factors, including other foods eaten at the same time.
Frequently Asked Questions
- Is papaya a good source of iron? No, papaya is low in iron. A 100 g serving provides about 0.25 mg, or roughly 1–3% of typical daily needs depending on your reference.
- Does the vitamin C in papaya really help with iron? Yes. Vitamin C can increase absorption of non-heme iron from plant foods when consumed in the same meal. Papaya contains far more vitamin C than most fruits, so even a small serving can support iron uptake.
- How much papaya is one serving? A typical serving is about 1 cup of chopped papaya, or roughly 145 g. A small fruit is close to one serving, while a medium fruit is closer to two.
- Which foods pair best with papaya for iron? Legumes, tofu, dark leafy greens, nuts, seeds, and fortified grains. Add lime or lemon too, since additional vitamin C can further enhance absorption.
- Can I use this calculator for dried papaya? No. Dried papaya has a very different water content and nutrient density. Stick to raw, fresh papaya for this calculation.
