Passion fruit is one of the most nutrient-dense tropical fruits — a single cup of fresh purple passion fruit pulp delivers about 229 calories, yet it also provides more than 24 grams of fiber and roughly 27 mg of vitamin C. Because people usually eat passion fruit by the spoonful, the half-cup, or the whole fruit rather than weighing it on a kitchen scale, calorie estimates tend to be all over the place. This Passion Calories Per Cup Calculator removes the guesswork by converting any common measurement — cups, tablespoons, teaspoons, grams, ounces, or whole fruits — into accurate calorie and macronutrient estimates in seconds.
Built from USDA standard reference values for raw purple passion fruit, the tool calculates calories, carbohydrates, fiber, sugar, protein, and fat, and it shows you the exact weight in grams behind the serving. That makes it easy to log meals in apps like MyFitnessPal or Cronometer, plan a high-fiber diet, or track calories for weight loss. Whether you're blending passion fruit into a morning smoothie, spooning it over yogurt, or just curious how one fruit compares to a full cup, this calculator gives you reliable numbers instantly — no food scale required.
🍇 Passion Fruit Calories per Cup Calculator
Turn any passion fruit serving — cups, spoons, fruits, or grams — into calories and macros.
How to Use This Calculator
To get started, type an amount into the number field and pick the matching unit from the dropdown — cups, tablespoons, teaspoons, grams, ounces, or whole fruits. The calculator accepts decimals, so values like 0.5, 1.25, or 2.75 work perfectly. If you prefer to tap instead of type, the quick-fill chips above the button insert common servings instantly: 1 cup, ½ cup, 1 tablespoon, 100 g, or a single fruit.
After you hit Calculate, you'll see a full nutrition snapshot: calories, total carbs, net carbs, fiber, sugar, protein, fat, and the total weight in grams. A short two-step breakdown underneath explains exactly how the number was derived, and the summary line gives you a ready-to-paste sentence for your food diary or tracking app.
Nutrition Values Used in This Calculator
All values come from the USDA FoodData Central database for raw purple passion fruit (passion-fruit, granadilla, purple, raw). The reference portion is 100 g of edible pulp with seeds, which is roughly a half-cup.
| Nutrient | Per 100 g | Per 1 cup (236 g) |
|---|---|---|
| Calories | 97 kcal | 229 kcal |
| Carbohydrates | 23.4 g | 55.2 g |
| Dietary fiber | 10.4 g | 24.5 g |
| Sugars | 11.2 g | 26.4 g |
| Protein | 2.2 g | 5.2 g |
| Total fat | 0.7 g | 1.7 g |
Net carbs are calculated by subtracting fiber from total carbs — a helpful number for low-carb and ketogenic meal planning.
How the Math Works
The calculation is a simple two-step conversion. First, the selected unit is converted to grams:
Grams = amount × grams per unit
0.5 cup × 236 g/cup = 118 g
Then calories and every macronutrient are scaled proportionally from the 100 g reference values:
Calories = grams ÷ 100 × 97
118 g ÷ 100 × 97 = 114.5 kcal
The same proportion applies to carbs, fiber, sugar, protein, and fat, so you always see a consistent macro profile for whatever portion you entered. The reference data and calculation approach follow the standard per-100-gram method used by nutrition databases worldwide.
Worked Examples
Example 1 — Smoothie prep. You add 1 full cup of passion fruit pulp to a morning smoothie. Grams = 1 × 236 = 236 g. Calories = 236 ÷ 100 × 97 = 229 kcal. Fiber = 236 ÷ 100 × 10.4 = 24.5 g — already more than two-thirds of the daily fiber target for most adults. If you're logging the whole drink, our smoothie calorie calculator can total up all the other ingredients too.
Example 2 — Yogurt topping. You spoon 2 tablespoons over Greek yogurt. Grams = 2 × 14.75 = 29.5 g. Calories = 29.5 ÷ 100 × 97 = 28.6 kcal, with only 3.3 g carbs and 0.7 g fiber.
Example 3 — Snack by the fruit. Three average purple passion fruits (edible portion 18 g each) give 54 g total. Calories = 54 ÷ 100 × 97 = 52.4 kcal — a very reasonable low-calorie snack with 5.6 g fiber.
Tips for Accurate Tracking
- Weigh once, estimate after. If you own a food scale, weigh the pulp of your usual fruit once — the edible portion of a medium purple passion fruit is around 18 g, but it can range from 12 g to 25 g depending on size and variety.
- Don't forget the seeds. Passion fruit seeds are edible and included in the USDA data; they contribute some fiber and a little fat. Don't scoop them out when logging.
- Check the variety. Yellow passion fruit (Passiflora edulis flavicarpa) is lower in calories — about 60 kcal per 100 g — and more tart. Use the gram setting if you're eating the yellow type.
- Beware added sugar. Passion fruit pulp sold frozen or in cans often has added sugar or syrup. Always check the label; if sweetened, our numbers will undercount.

Frequently Asked Questions
Is passion fruit high in calories? No. At about 97 kcal per 100 g, passion fruit is moderate for a tropical fruit — comparable to bananas (89 kcal) but with roughly twice the fiber. A whole fruit is only about 18 kcal.
Do the seeds add significant calories? The seeds are included in the USDA values used here and make up a large part of the fiber count. They contribute only a small amount of fat, so the calorie total stays low.
Is frozen passion fruit nutritionally the same? Unsweetened frozen pulp is very close to fresh fruit — freezing doesn't change calories or macros meaningfully. If the package lists added sugar or syrup, add those calories separately.
Can I use this for passion fruit juice? Not directly. Juice has removed almost all the fiber (around 0.2–0.5 g per 100 g) and has a slightly different sugar profile. For blended smoothies that include whole pulp, this calculator is a good match.
Why does a whole fruit weigh so little? Most of a passion fruit's weight is the thick rind, which isn't eaten. The edible seeds and pulp of a medium fruit typically weigh 15–20 g — the 18 g figure used here is the average edible portion.
