Pumpkin is a nutrient-dense, low-calorie food that fits perfectly into weight management, diabetic, and general healthy eating plans. Whether you're roasting cubes, blending soup, or baking a pie, knowing the exact calorie count per serving helps you stay on track with your daily goals.
This calculator lets you enter the weight of your pumpkin (in grams or ounces) and choose the preparation method — raw, boiled, roasted, or canned — to get an accurate calorie estimate. It also breaks down the macronutrients (carbs, protein, fat) and fiber content, so you can log your meal with confidence. Perfect for meal preppers, dietitians, and anyone curious about the nutritional profile of this versatile squash.

How to Use This Tool
Enter the weight of your pumpkin in grams or ounces, select the preparation method (raw, boiled, roasted, or canned), and click Calculate. The tool instantly returns the total calories, carbohydrates, protein, fat, and fiber for that serving. Use the Reset button to clear results and start a new calculation.
Tip: For the most accurate results, weigh your pumpkin after peeling and seeding (edible portion). If using canned pumpkin, note that it is typically unsweetened puree — sweetened pie filling has different values.
Formula Explained
The calculator uses standard USDA nutrition data per 100 grams of edible pumpkin for each preparation method. The formula is simple:
Calories per serving = (Calories per 100 g) × (Weight in grams / 100)
Macronutrients (carbs, protein, fat, fiber) are calculated the same way. The per-100g values are sourced from the USDA FoodData Central database, which provides reliable averages for raw, boiled, roasted, and canned pumpkin.
Worked Examples
Example 1: 200 g raw pumpkin
Calories = 26 × (200/100) = 52 kcal
Carbs = 6.5 × 2 = 13 g, Protein = 1.0 × 2 = 2 g, Fat = 0.1 × 2 = 0.2 g, Fiber = 0.5 × 2 = 1 g
Example 2: 150 g roasted pumpkin (about 1 cup cubed)
Calories = 34 × 1.5 = 51 kcal
Carbs = 7.6 × 1.5 = 11.4 g, Protein = 1.4 × 1.5 = 2.1 g, Fat = 0.3 × 1.5 = 0.45 g, Fiber = 1.1 × 1.5 = 1.65 g
Example 3: 245 g canned pumpkin (standard 1-cup serving)
Calories = 34 × 2.45 = 83.3 kcal
Carbs = 8.1 × 2.45 = 19.8 g, Protein = 1.1 × 2.45 = 2.7 g, Fat = 0.3 × 2.45 = 0.74 g, Fiber = 2.8 × 2.45 = 6.86 g
Factors Affecting Accuracy
The values in this calculator are averages. Actual nutrient content can vary based on pumpkin variety (e.g., sugar pie vs. carving pumpkins), growing conditions, and cooking time. Boiling may leach some water-soluble nutrients, while roasting concentrates sugars slightly. For precise tracking, always use the specific nutrition label on packaged products.
Real-World Applications
Pumpkin is a staple in fall meal prep, soups, curries, baked goods, and smoothies. Knowing its calorie density helps you portion it correctly — especially when combined with higher-calorie ingredients like cream, butter, or sugar. This tool is useful for:
- Meal planning and calorie budgeting
- Diabetic meal design (pumpkin is low glycemic)
- Fiber intake tracking
- Comparing raw vs. cooked yields
Frequently Asked Questions
Is pumpkin a low-calorie food? Yes — raw pumpkin has only 26 kcal per 100 g, making it one of the lowest-calorie vegetables. Even roasted, it stays under 35 kcal per 100 g.
Does cooking change the calorie count? The calorie density per gram increases slightly because water evaporates, concentrating the solids. However, the total calories in the original raw weight remain similar — the difference is mostly due to water loss.
Can I use this for pumpkin seeds? No — this calculator is for the flesh only. Pumpkin seeds are much higher in calories and fat. For seed nutrition, refer to a dedicated seed calculator.
What about pumpkin pie filling? Sweetened pie filling has added sugar and often evaporated milk, raising calories significantly. This tool is for plain pumpkin only.
