Peppers are one of the most versatile vegetables in the kitchen, adding color, crunch, and a mild heat to countless dishes. But if you're tracking calories, you might wonder exactly how many calories are in the peppers you eat. This calculator gives you the precise calorie count per 100 grams for a wide range of pepper varieties — from sweet bell peppers to fiery habaneros — so you can log your meals with confidence.
Simply select your pepper type, enter the weight you plan to eat, and the tool instantly calculates total calories, plus a breakdown of carbohydrates, protein, and fat. You can also adjust for cooked vs. raw peppers, since cooking can change the calorie density. Whether you're meal prepping, following a calorie budget, or just curious about your favorite pepper, this tool makes nutrition tracking quick and easy.

How to Use This Tool
Using the pepper calorie calculator is straightforward. Start by selecting the pepper variety from the dropdown — options include common types like red, green, and yellow bell peppers, jalapeños, serranos, habaneros, Thai chilies, and dried ground cayenne or paprika. Next, enter the weight of the peppers you plan to eat. You can enter the weight in grams or ounces; the calculator will convert ounces to grams automatically (1 oz = 28.35 g).
Then choose whether your peppers are raw or cooked. Cooking peppers, especially boiling or steaming, can slightly reduce their calorie density because they absorb water and lose some solids. The calculator applies a 10% reduction for cooked peppers to reflect this. After clicking Calculate, you'll see the total calories and a breakdown of carbohydrates, protein, and fat. The result also shows the step-by-step calculation so you can verify the math.
If you're in a hurry, use the quick-fill buttons to set common weights (50 g, 100 g, 150 g, 200 g). The reset button clears all inputs and results.
How It Works
The calorie values used in this calculator are based on standard USDA FoodData Central entries for each pepper type. For raw peppers, the values represent the edible portion per 100 grams. The macronutrient breakdown (carbs, protein, fat) is also derived from the same database. For dried spices like cayenne and paprika, the values are much higher because water has been removed, concentrating the nutrients.
The calculation is simple: calories = (calories per 100g × weight in grams) / 100. For cooked peppers, we multiply by 0.9 to account for the typical water absorption during cooking. This is an approximation; the exact change depends on cooking method and duration.
For reference, here are the base values used (per 100 g raw):
| Pepper Type | Calories (kcal) | Carbs (g) | Protein (g) | Fat (g) |
|---|---|---|---|---|
| Red bell pepper | 31 | 6.0 | 1.0 | 0.3 |
| Green bell pepper | 20 | 4.6 | 0.9 | 0.2 |
| Yellow bell pepper | 27 | 6.3 | 1.0 | 0.2 |
| Jalapeño | 29 | 6.5 | 0.9 | 0.4 |
| Serrano | 32 | 6.7 | 1.7 | 0.4 |
| Habanero | 40 | 9.5 | 1.9 | 0.6 |
| Thai chili | 40 | 8.8 | 1.9 | 0.5 |
| Cayenne (dried) | 318 | 56.6 | 12.0 | 17.3 |
| Paprika (dried) | 282 | 53.9 | 14.1 | 12.9 |
Worked Examples
Example 1: You eat 150 g of raw red bell pepper. Calories = 31 × 150 / 100 = 46.5 kcal. Carbs = 6.0 × 150 / 100 = 9.0 g. Protein = 1.0 × 150 / 100 = 1.5 g. Fat = 0.3 × 150 / 100 = 0.45 g.
Example 2: You use 2 oz (about 57 g) of raw jalapeño in a salsa. First convert: 2 oz × 28.35 = 56.7 g. Calories = 29 × 56.7 / 100 = 16.4 kcal. Carbs = 6.5 × 56.7 / 100 = 3.7 g.
Example 3: You add 10 g of dried cayenne to a chili. Calories = 318 × 10 / 100 = 31.8 kcal. Note that dried spices are calorie-dense, so even small amounts add up.
Tips & Best Practices
- Weigh peppers after removing stems and seeds, as those parts are not typically eaten.
- For recipes that use multiple pepper types, calculate each separately and sum the results.
- If you're tracking macros, remember that the carbohydrate value includes fiber. For net carbs, subtract fiber (bell peppers have about 2 g fiber per 100 g).
- Roasting or grilling peppers without added oil doesn't significantly change their calorie content, but the 10% cooked adjustment is a reasonable estimate for boiled or steamed peppers.
- Dried peppers and ground spices are much more calorie-dense than fresh — always weigh them carefully.
Common Mistakes to Avoid
- Forgetting to convert ounces to grams. Always use the unit selector or do the conversion manually.
- Using the raw value for cooked peppers without adjustment. While the difference is small, it can matter for precise tracking.
- Confusing dried cayenne with fresh cayenne peppers. Fresh cayenne has about 40 kcal per 100 g, while dried has 318 kcal per 100 g.
- Not accounting for added oils or butter when cooking peppers — those add significant calories.
Frequently Asked Questions
Are bell peppers low in calories? Yes, all bell peppers are very low in calories. A whole medium red bell pepper (about 119 g) has only about 37 kcal, making them an excellent choice for weight management.
Do spicy peppers have more calories? Not necessarily. The heat comes from capsaicin, which has no calories. The calorie difference between varieties is mainly due to water and sugar content. Dried peppers, however, are much higher in calories because they're concentrated.
Can I use this calculator for other vegetables? This tool is specific to peppers, but you can find similar calculators for other vegetables on this site, such as the vegetable calories per 100g calculator.
How accurate are the values? The values are based on USDA FoodData Central, which is the standard reference for nutrition data. Individual peppers may vary slightly due to growing conditions and ripeness.
