Ever wonder how many calories are really in that bowl of lentils? This Lentil Calories Per Cup Calculator gives you a fast, evidence-based answer in seconds. Just choose your lentil variety (brown, red, black beluga, or French puy), select whether they're cooked or dried, and enter your portion in cups. You'll instantly see the calorie count plus the full macro breakdown — protein, carbohydrates, fiber, and fat.
Calories are only half the story. Lentils are one of the most nutrient-dense legumes: a single cooked cup delivers roughly 18 grams of plant protein and 15 grams of gut-friendly fiber for around 230 calories. Whether you are meal-prepping, tracking macros, or just trying to make sense of a serving size, this tool takes the guesswork out of portion math.
All values are based on standard USDA nutrition data for cooked (boiled) and dried lentils, rounded to realistic whole numbers. Bookmark it for every soup, curry, and salad.

How to Use This Calculator
Using it is straightforward:
- Pick your lentil type. Brown and green lentils are the most common and hold their shape well; red lentils break down quickly; black beluga and French puy have a firmer texture. Each option uses slightly different calorie and macro values.
- Choose cooked or dried. Dried lentils are much more calorie-dense per cup because most of the water has been removed. A cup of dried lentils swells to roughly 2.5 to 3 cups cooked, so always select the state that matches what is actually on your plate.
- Enter the number of cups. Use decimals for partial servings — for example, 0.5 for half a cup or 1.25 for a cup and a quarter. The result updates instantly when you click Calculate.
- Read your macros. The panel shows calories plus protein, carbs, fiber, and fat for the exact portion you entered.
How It Works: The Data Behind the Numbers
The calculator uses standard nutrition values from the USDA FoodData Central database, the go-to reference for food composition data in the United States. For cooked lentils, the base reference is 116 calories per 100 grams; for raw (dried) lentils, it is about 353 calories per 100 grams. These figures are converted to a 1-cup basis using standard cup weights.
A standard US measuring cup of cooked lentils weighs approximately 198 grams, which gives about 230 calories, 17.9 grams of protein, 39.9 grams of carbs, 15.6 grams of fiber, and 0.8 grams of fat. Dried lentils weigh about 192 grams per cup and deliver roughly 676 calories with 47.3 grams of protein and 20.5 grams of fiber.
Red lentils, black beluga lentils, and French puy lentils have slightly different values because their moisture content and seed structure differ. The calculator reflects those differences, but all numbers are rounded for practical portion tracking. If you prefer weighing your lentils, think of cooked lentils as roughly 1.16 kcal per gram and dried lentils as about 3.52 kcal per gram.
Worked Examples
Example 1: Standard cooked serving. You eat 1 cup of cooked brown lentils with a salad. Input: Brown/Green, Cooked, 1 cup → 230 kcal, 17.9 g protein, 15.6 g fiber. That is an excellent calorie-to-protein ratio for a plant food.
Example 2: Dry-lentil recipe math. You are cooking a big batch from 2 cups of dried red lentils. Input: Red, Dried, 2 cups → about 1,374 kcal for the entire dry batch. After cooking, that yields roughly 5 to 6 cups of cooked lentils, so each cooked cup comes in around 220–275 kcal depending on how much water is absorbed.
Example 3: Half-cup side dish. You add 1/2 cup of cooked French puy lentils to a grain bowl. Input: French Puy, Cooked, 0.5 cup → about 113 kcal and 5.3 g protein. It’s a modest calorie addition that boosts fiber and texture.
Lentil Nutrition at a Glance
Here is a quick reference for 1 US cup of lentils in different forms. Values are approximate and rounded from USDA data.
| Form | Calories | Protein (g) | Carbs (g) | Fiber (g) | Fat (g) |
|---|---|---|---|---|---|
| Cooked brown/green (1 cup) | 230 | 17.9 | 39.9 | 15.6 | 0.8 |
| Cooked red (1 cup) | 210 | 16.0 | 37.0 | 13.0 | 0.7 |
| Cooked black beluga (1 cup) | 240 | 18.0 | 41.0 | 16.0 | 0.9 |
| Cooked French puy (1 cup) | 225 | 17.5 | 39.0 | 15.0 | 0.8 |
| Dried lentils, any variety (1 cup) | 676 | 47.3 | 121.6 | 20.5 | 2.0 |
Dried lentils look dramatically higher in calories because they are a concentrated, nearly water-free ingredient. Once cooked, they absorb water and increase in volume, so the calories per cup drop.
Tips & Common Mistakes
- Always match the state to your plate. The most common error is entering dried lentils as if they were cooked. A cup of dry lentils is not a single serving — it turns into multiple servings once hydrated.
- Account for added fats and seasonings. Lentils themselves are nearly fat-free, but sautéing them in oil, adding butter, or using rich curry sauces adds calories quickly. Count those extras separately.
- Use a measuring cup, not a bowl. An average soup bowl can hold 1.5 to 2 cups of cooked lentils. Weighing or using a standard measuring cup is far more accurate than eyeballing.
- Compare with other legumes. If you are tracking calories for a mixed-bean soup, the dried bean calorie calculator can help you compare bean varieties side by side.
Frequently Asked Questions
Are lentil calories the same raw and cooked? No. Dried lentils have about three times more calories per cup because they contain almost no water. When you cook them, they absorb water and about triple in volume, so a cup of cooked lentils has far fewer calories than a cup of dried.
Which lentil variety has the fewest calories? In this calculator, cooked red lentils come in lowest at about 210 kcal per cup, followed closely by French puy at 225. The differences are small, though — variety matters far less than portion size and cooking method.
Why is my measured calorie count different from the package label? Packages often use slightly different moisture content or serving sizes. Many brands list a serving as 1/4 cup dry (about 45–50 g), which is roughly 1/2 cup cooked. Calories per gram should still be within a few percent of the USDA data used here.
Do I need to count lentils if I’m trying to lose weight? Lentils are low in calorie density and very high in fiber and protein, so they help you feel full. Still, portions matter — 2 cups of cooked lentils is about 460 calories, which is a substantial part of a meal. For a similar look at chickpeas, see the chickpea protein calculator.
