Passion fruit packs a surprising amount of carbohydrate into a small, seed-filled package. Per 100 grams of raw purple passion fruit, total carbohydrates come to roughly 23.4 grams — but about 10.4 grams of that is dietary fiber, leaving around 13 grams of net carbs and about 11.2 grams of natural sugars. Because the fruit is usually eaten by the piece rather than weighed, most people have no idea how many carbs are actually on their plate. This calculator converts any serving — whole fruits, grams, ounces, or cups of pulp — into total carbs, net carbs, fiber, sugars, and estimated calories in a single click.
It's designed for keto and low-carb dieters who track net carbohydrates, people with diabetes who want predictable sugar intake, and nutrition enthusiasts logging meals. The tool also shows a step-by-step breakdown of every calculation, so you always know exactly how the numbers were derived, using reference values from the USDA FoodData Central database.
🍈 Passion Fruit Carbs Calculator
Find total carbs, net carbs, fiber, natural sugars, and calories for any serving of passion fruit.
How to Use This Tool
Enter the amount of passion fruit you plan to eat and choose the unit that matches how you’re measuring it — grams, whole fruits, ounces, or cups of pulp. Press Calculate Carbs to see total carbohydrates, net carbs, dietary fiber, natural sugars, and estimated calories for that exact serving. The result panel also shows the serving weight in grams and a step-by-step breakdown so you can verify every number.
If you usually eat one fruit at a time, use the quick-fill buttons: 1 fruit assumes an average whole passion fruit contains about 18 g of edible pulp and seeds. For larger recipes, weigh the pulp and switch to grams, or fill a measuring cup if you prefer volume.
How It Works
All values in this calculator are based on the USDA reference for raw purple passion fruit (Passiflora edulis), which reports per 100 g of edible portion:
- Total carbohydrate: 23.38 g
- Dietary fiber: 10.4 g
- Total sugars: 11.2 g
- Energy: 97 kcal
The math is a simple proportional scaling: nutrient per 100 g × (serving weight in g ÷ 100). Net carbs are then calculated as total carbs minus dietary fiber, the standard convention used in keto and low-carb meal planning. Because passion fruit is unusually high in fiber relative to its sugar content, its net-carb value is much lower than its total-carb value.

Worked Examples
Example 1 — One whole fruit. A single fruit contains about 18 g of edible pulp. At 18 g, total carbs = 18 × 23.38 ÷ 100 ≈ 4.2 g, fiber ≈ 1.9 g, so net carbs ≈ 2.3 g, and energy ≈ 17 kcal.
Example 2 — Half a cup of pulp. A half cup weighs about 120 g. Total carbs ≈ 28.1 g, fiber ≈ 12.5 g, net carbs ≈ 15.6 g, and calories ≈ 116 kcal. This shows how quickly a large bowl of passion fruit adds up for a low-carb budget.
Reference: Standard Values Per 100 g
| Nutrient | Raw Purple Passion Fruit |
|---|---|
| Total carbohydrates | 23.38 g |
| Dietary fiber | 10.4 g |
| Total sugars | 11.2 g |
| Net carbs (calculated) | approx. 12.98 g |
| Energy | 97 kcal |
| Water | 72.93 g |
| Protein | 2.2 g |
| Fat | 0.7 g |
Values apply to raw purple passion fruit. Yellow varieties and passion fruit juice or nectar can have different sugar and carb profiles; check the label or a specific USDA entry when using processed products.
Tips & Best Practices
- Use a digital kitchen scale for accuracy. Weighing the scooped pulp is more reliable than estimating by fruit size, which varies widely.
- For keto, track net carbs (total carbs minus fiber) rather than total carbs. One whole passion fruit contributes about 2.3 net carbs — easy to fit into a 20–50 g daily limit.
- For diabetes management, remember that natural sugars still raise blood glucose. Fiber slows digestion, but portion control remains important — test your own response if you are insulin-dependent.
- Frozen passion fruit pulp and bottled passion fruit juice often contain added sugar or are diluted; always re-check the nutrition label.
Frequently Asked Questions
Why is fiber subtracted from carbs? Dietary fiber is a carbohydrate that is not fully digested and absorbed by the body, so many low-carb plans subtract it from total carbs to estimate net carbs. Net carbs is not a legally defined term, but it is a useful practical measure.
How many carbs are in one passion fruit? Assuming 18 g of edible pulp, one fruit has about 4.2 g total carbs and about 2.3 g net carbs.
Is passion fruit keto-friendly? In moderation, yes — a single fruit contributes roughly 2.3 g net carbs and 17 kcal, and the seeds provide texture and fiber. Larger portions add up quickly, so weigh or count pieces carefully.
