Brussels sprouts are a nutrient-dense cruciferous vegetable, but their calorie content can vary depending on how they're prepared. This calculator helps you quickly determine the calories in Brussels sprouts based on the weight you plan to eat, with options for raw, boiled, and roasted preparations.
Simply enter the weight of your Brussels sprouts in ounces (or grams), select the preparation method, and the calculator will provide the total calories, calories per ounce, and a breakdown of macronutrients. Whether you're tracking calories for weight management, meal planning, or just curious about your vegetable intake, this tool gives you accurate estimates based on standard USDA nutrition data.
Use the quick-fill buttons to instantly calculate for common serving sizes, or enter your own weight for a custom result. The calculator also includes a handy reference table for typical serving sizes.

How to Use This Tool
Enter the weight of your Brussels sprouts in the input field, select the unit (ounces or grams), and choose the preparation method that matches how you'll eat them. The calculator uses standard USDA nutrition data to estimate calories and macronutrients. You can also use the quick-fill buttons for common serving sizes like 3 oz or 4 oz, which are typical for a side dish.
For the most accurate results, weigh your sprouts before cooking if you select raw, or after cooking if you select boiled or roasted. The calculator accounts for the fact that cooking methods change water content and, in the case of roasting, add oil.
How It Works
The calorie values are based on the USDA FoodData Central database. Raw Brussels sprouts contain approximately 43 calories per 100 grams, which translates to about 9.9 calories per ounce. Boiled sprouts have slightly more calories per ounce (about 11.3) because they absorb some water and lose volume, concentrating the calories. Roasted sprouts, which are typically tossed in oil, have significantly more calories—around 22.7 per ounce—due to the added fat.
The calculator multiplies the weight you enter by the appropriate calorie-per-ounce factor for your selected preparation. It also calculates protein, carbohydrate, and fat content using the same proportional method. This gives you a quick snapshot of the nutritional profile of your serving.
Worked Examples
Example 1: You plan to eat 4 ounces of raw Brussels sprouts. Enter 4 in the weight field, select ounces, and choose Raw. The calculator will show approximately 39.6 kcal, with 3.6 g protein, 8.0 g carbs, and 0.4 g fat.
Example 2: You have 150 grams of roasted Brussels sprouts. Enter 150, select grams, and choose Roasted. The calculator converts to about 5.29 ounces and estimates 120 kcal, with 4.8 g protein, 13.8 g carbs, and 6.9 g fat.
Tips & Best Practices
- Weigh your sprouts after trimming the stems and removing any yellow leaves, as these parts are not typically eaten.
- If you're tracking calories for weight management, remember that cooking methods like roasting with oil can add 10-15 calories per tablespoon of oil used.
- For meal prep, you can calculate the total calories for a batch and divide by the number of servings to get per-serving values.
- Use a kitchen scale for the most accurate measurements, especially if you're following a strict diet plan.
Factors Affecting Accuracy
The calorie values are averages from USDA data and can vary slightly based on the specific variety of Brussels sprouts, growing conditions, and cooking time. Boiling time affects water absorption, and the amount of oil used in roasting can vary significantly. For the most precise tracking, consider weighing your sprouts and noting the exact amount of oil added.

Frequently Asked Questions
Are Brussels sprouts good for weight loss?
Yes, Brussels sprouts are low in calories and high in fiber, which can help you feel full. A 4-ounce serving of raw sprouts has only about 40 calories, making them an excellent addition to a weight-loss diet.
Do cooked Brussels sprouts have more calories than raw?
Boiled sprouts have slightly more calories per ounce because they lose water and become denser. Roasted sprouts have significantly more calories due to added oil. The difference is mainly from the cooking fat, not the sprouts themselves.
Can I use this calculator for frozen Brussels sprouts?
Frozen sprouts are typically similar in calorie content to raw sprouts, but check the package for any added sauces or seasonings. If they're plain, you can use the raw or boiled option depending on how you prepare them.
