Radishes are a crisp, peppery root vegetable often enjoyed raw in salads, as a crunchy snack, or pickled. Low in calories but rich in water and fiber, they are a popular choice for weight management and healthy eating. This Radish Calorie Calculator helps you quickly estimate the calories, carbohydrates, protein, and fat in any amount of radishes — whether you’re tracking macros, planning a meal, or just curious about the nutritional profile of this humble vegetable.
Simply enter the weight of radishes (in grams or ounces) and select the type (raw, pickled, or cooked). The calculator provides an instant breakdown of calories and macronutrients, making it easy to fit radishes into your daily diet. Perfect for nutrition enthusiasts, dietitians, and anyone following a calorie-controlled eating plan.

How to Use This Tool
Using the Radish Calorie Calculator is straightforward. Enter the weight of radishes you plan to eat — either in grams or ounces — and select the type of radish (raw, pickled, or cooked). The calculator instantly displays the total calories, carbohydrates, protein, and fat. You can also click one of the preset buttons (e.g., 50 g, 85 g, 100 g) to quickly test common serving sizes. After clicking "Calculate," the result area shows a detailed breakdown along with a step-by-step explanation of the math, so you can see exactly how the numbers are derived.
Nutritional Profile of Radishes
Radishes are a low-calorie, nutrient-dense vegetable. According to the USDA FoodData Central database, 100 grams of raw radishes contain approximately 16 calories, 3.4 g of carbohydrates (including 1.6 g of fiber and 1.9 g of sugar), 0.68 g of protein, and 0.1 g of fat. They are also an excellent source of vitamin C (about 14.8 mg per 100 g, or 25% of the Daily Value) and provide small amounts of potassium, folate, and calcium. Pickled radishes have slightly more calories (around 18 kcal per 100 g) due to added sugar in the brine, while boiled radishes lose some water-soluble nutrients and have about 14 kcal per 100 g. The fiber content in radishes supports digestive health, and their high water content (over 95%) makes them a hydrating, low-energy-density food ideal for weight management.
Formula Explained
The calculation uses a simple proportional formula: Nutrient Value = (Weight in grams / 100) × Nutrient per 100g. For example, if you have 150 g of raw radishes, the calories would be (150 / 100) × 16 = 24 kcal. The same factor is applied to carbohydrates, protein, and fat. If you enter the weight in ounces, the calculator first converts ounces to grams using the conversion factor 1 oz = 28.3495 g. This method is standard in nutrition analysis and ensures accurate results based on established reference data from the USDA.
Worked Examples
Example 1: You eat 85 g (about 3 oz) of raw radishes in a salad. Calories = (85/100) × 16 = 13.6 kcal. Carbs = (85/100) × 3.4 = 2.89 g. Protein = (85/100) × 0.68 = 0.58 g. Fat = (85/100) × 0.1 = 0.09 g.
Example 2: You snack on 50 g of pickled radishes. Calories = (50/100) × 18 = 9 kcal. Carbs = (50/100) × 3.8 = 1.9 g. Protein = (50/100) × 0.5 = 0.25 g. Fat = (50/100) × 0.2 = 0.1 g.
Example 3: You have 200 g of boiled radishes as a side dish. Calories = (200/100) × 14 = 28 kcal. Carbs = (200/100) × 2.9 = 5.8 g. Protein = (200/100) × 0.6 = 1.2 g. Fat = (200/100) × 0.1 = 0.2 g.
Tips for Accurate Tracking
For the most accurate calorie and macronutrient tracking, weigh your radishes on a kitchen scale rather than relying on volume estimates. A medium-sized raw radish (about 15–20 g) is roughly equivalent to 2–3 calories. If you are using pickled radishes, be aware that the brine may contain added sugar and sodium, which can affect the total calorie count and your daily sodium intake. For cooked radishes, boiling can leach some water-soluble vitamins (like vitamin C) into the cooking water, but the calorie and macronutrient values remain relatively stable. Always check the label on packaged pickled radishes for exact nutritional information, as brands may vary.
Frequently Asked Questions
Are radishes good for weight loss? Yes, radishes are very low in calories and high in water and fiber, which can help you feel full with minimal caloric intake. They are a great addition to salads, slaws, and vegetable platters for anyone on a calorie-restricted diet.
Do radishes have any carbs? Yes, raw radishes contain about 3.4 g of carbohydrates per 100 g, of which about 1.6 g is fiber and 1.9 g is natural sugar. This makes them a low-carb vegetable suitable for most low-carb and keto diets in moderate amounts.
Can I use this calculator for other radish varieties? The calculator uses average values for common red radishes. Daikon radish, for example, has a slightly different nutritional profile (about 18 kcal per 100 g, 4.1 g carbs). For precise tracking of other varieties, refer to the USDA FoodData Central database or use a specialized tool like the Broccoli Calorie Calculator for comparison.
How many calories are in a single radish? A small raw radish (about 15 g) contains roughly 2.4 calories. A larger radish (20 g) has about 3.2 calories. Use the calculator with the weight of one radish to get an exact number.
Is there a difference between red and white radishes? Red radishes and white radishes (like daikon) have similar calorie counts, but daikon is slightly higher in carbs and vitamin C. The calculator is based on red radish data; for daikon, you may need to adjust the values manually.
