Radishes are one of the lowest-calorie vegetables you can snack on, yet their crisp crunch can make a salad or snack feel surprisingly satisfying. This Radish Calories Per Handful Calculator converts your handfuls into calories and macronutrients, so you can log your portion accurately without weighing every slice.
The calculator uses USDA nutrition data for raw radishes (about 16 kcal, 3.4 g carbs, 1.6 g fiber, 0.7 g protein, and 0.1 g fat per 100 g). Because a “handful” varies by hand size and how the radishes are cut, you can adjust the grams per handful — choose a quick preset or enter your own measured value. Results include total calories, per-handful calories, and a full carb/protein/fat/fiber breakdown.
Whether you’re tracking calories for weight loss, following a low-carb plan, or just meal-prepping for a healthy snack, this tool gives you a realistic, fast estimate in seconds.

How to Use This Calculator
Start by entering the number of handfuls you plan to eat. You can use decimals like 0.5 for half a handful or 2.5 for a generous snack. Next, set how many grams your handful actually contains. The three preset buttons give reasonable estimates for small, standard, and heaping handfuls, but for the most accurate result, weigh one of your own handfuls once and use that number as your personal default.
- Type the number of handfuls in the first field.
- Choose a preset gram weight or type your own grams per handful.
- Click Calculate Calories to see total kcal, calories per handful, and the full macronutrient picture.
- Use Reset to clear everything, or Copy Result to paste the summary into your food diary.
A similar approach is used in the okra calories per handful tool if you want to compare another low-calorie crunchy vegetable.
The Math Behind It
Raw radishes are about 95% water, which is why their calorie density is so low. Per 100 grams, the USDA FoodData Central entry for raw radish lists approximately:
Reference values per 100 g raw radish
- Energy: 16 kcal
- Carbohydrate: 3.4 g
- Fiber: 1.6 g
- Protein: 0.7 g
- Fat: 0.1 g
The calculator multiplies your portion weight by these values. The basic formula is:
Total calories = portion weight (g) × (calories per 100 g ÷ 100)
For example, 150 g of radishes = 150 × 0.16 = 24 kcal. The same proportion applies to carbs (× 0.034), protein (× 0.007), fat (× 0.001), and fiber (× 0.016).
Because radishes are so low in calories, small weighing errors change the total very little. Even a 20 g error shifts the calorie count by about 3 kcal. You can look up the official nutrient profile on the USDA FoodData Central.
Worked Examples
Example 1: Standard snack — You eat 2 standard handfuls (100 g each), for 200 g total. The calculator reports 32 kcal, 6.8 g carbs, 3.2 g fiber, 1.4 g protein, and 0.2 g fat. That’s a satisfying crunchy snack for fewer calories than many other snack foods.
Example 2: Salad topping — You add 0.5 handful (50 g) of sliced radishes to lunch. Total = 8 kcal, 1.7 g carbs, 0.8 g fiber, 0.4 g protein. If you’re tracking net carbs, that’s only 0.9 g net carbs.
Example 3: Meal-prep container — A container holds 3 heaping handfuls at 150 g each, so 450 g. That’s 72 kcal, 15.3 g carbs, 7.2 g fiber, 3.2 g protein, and less than 0.5 g fat. Radishes are a great volume food for weight-management plans.
Portion Benchmarks & Reference Values
These gram estimates are typical for raw radish portions. Use them as a starting point, then adjust the grams field to match your actual serving.
| Portion description | Approx. weight | Calories | Carbs |
|---|---|---|---|
| Small handful (chopped) | 75 g | 12 kcal | 2.6 g |
| Standard handful (sliced) | 100 g | 16 kcal | 3.4 g |
| Heaping handful | 150 g | 24 kcal | 5.1 g |
| 1 cup sliced radish | 116 g | 19 kcal | 3.9 g |
| 1 medium radish | 9 g | 1.4 kcal | 0.3 g |

Common Tracking Mistakes
- Assuming every handful weighs the same. Hand size, slicing thickness, and how tightly radishes are packed change the weight from roughly 70 g to 150 g.
- Counting toppings. Radishes pick up oil, butter, salt, or dip; the calories from those extras can easily exceed the radishes themselves.
- Ignoring fiber if you track net carbs. Radishes contribute roughly 1.6 g fiber per 100 g, so net carbs are only about 1.8 g per 100 g.
Pro tip: Weigh a handful once with a cheap kitchen scale before you start tracking. Most people are surprised by the actual number, and then you can use the preset that matches your usual portion.
Frequently Asked Questions
Are radishes actually 0 calories? No. They are very low calorie — about 16 kcal per 100 g — but not zero. A typical handful is around 10–25 kcal depending on size.
Do cooked radishes have the same calories? Raw and cooked radishes are similar, but cooking with oil or butter adds fat calories. Boiled radishes without added fat remain very low calorie.
Can this calculator help with net carbs? Yes. Take the carbs result and subtract the fiber result. For 100 g, that’s 3.4 − 1.6 = 1.8 g net carbs. This makes radishes a popular choice for low-carb eating plans.
