Peas are a versatile and nutrient-dense vegetable, but their calorie content can vary depending on how they are prepared and measured. Whether you are tracking your daily intake, planning a balanced meal, or simply curious about the energy in your favorite side dish, this calculator gives you an accurate estimate of the calories in a cup of peas based on the type and preparation method.
Simply choose the type of peas (green, snow, snap, or split), select the preparation (raw, cooked, or canned), and enter the number of cups. The calculator uses established USDA nutrition data to compute total calories, along with a breakdown of protein, carbohydrates, and fat. It is ideal for meal planners, fitness enthusiasts, and anyone following a calorie-conscious diet.
Use the quick-fill buttons to instantly load common serving sizes, or adjust the inputs to match your exact portion. The result area also shows a step-by-step calculation so you can see exactly how the numbers are derived.

How to Use This Tool
Using the pea calorie calculator is straightforward. Start by selecting the type of peas you have — green peas, snow peas, snap peas, or dried split peas. Next, choose the preparation method: raw, cooked (boiled), or canned (drained). These choices matter because cooking and canning change the water content and therefore the calorie density per cup.
Enter the number of cups you plan to eat. You can type a decimal like 0.75 or use the quick-fill buttons for common portions (½ cup, 1 cup, 2 cups). If you prefer to measure in half-cups, select that unit from the dropdown next to the number input. The calculator will automatically convert to full cups for the calculation.
Click the Calculate button to see your results. The output shows total calories, a macronutrient breakdown (protein, carbohydrates, fat), and a step-by-step explanation of how each value was derived. Use the Reset button to clear the form and start over.
How It Works
The calorie values used in this calculator are based on standard USDA FoodData Central entries for each pea type and preparation. For green peas, a cup of raw peas provides about 117 kcal, while cooked green peas are slightly higher at 134 kcal per cup because boiling removes some water and concentrates the nutrients. Canned green peas, which are packed in water and drained, come in at around 117 kcal per cup.
Snow peas and snap peas are much lower in calories — roughly 41–67 kcal per cup depending on preparation — because they are harvested young and contain more water. Dried split peas are the most calorie-dense, with about 672 kcal per cup raw, but after cooking they absorb water and drop to about 231 kcal per cup.
The calculator multiplies the per-cup calorie and macronutrient values by the number of cups you enter. For example, if you eat 1.5 cups of cooked green peas, the total is 134 × 1.5 = 201 kcal. The same multiplication applies to protein, carbs, and fat.
Worked Examples
Example 1: You are making a salad and add 1 cup of raw snow peas. The calculator shows 41 kcal, 2.8 g protein, 7.0 g carbs, and 0.2 g fat. That is a very light addition to your meal.
Example 2: You cook 2 cups of dried split peas for a hearty soup. Since the calculator uses cooked values, you get 231 × 2 = 462 kcal, with 32 g protein and 82 g carbs. This makes a filling, high-fiber main dish.
Example 3: You snack on ½ cup of canned green peas straight from the can. The result is 117 × 0.5 = 58.5 kcal, rounded to 59 kcal. A quick, low-calorie snack.
Tips & Best Practices
- Always measure peas after cooking, not before, because water absorption changes the volume and weight significantly.
- If you are tracking calories for weight management, remember that added butter, oil, or sauces will increase the total calorie count beyond what this calculator shows.
- For split peas, the raw value is useful for meal prep planning, but the cooked value is what you actually eat.
- Use a kitchen scale for the most accurate tracking — 1 cup of cooked green peas weighs about 160 grams.
Factors Affecting Accuracy
The values in this calculator are averages from USDA data. Actual calorie content can vary slightly based on the specific variety of peas, growing conditions, and how long they are cooked. Canned peas may also have added salt, which does not affect calories but is relevant for sodium intake. If you need precise numbers for a medical or athletic diet, consult the USDA FoodData Central database or a registered dietitian.
Frequently Asked Questions
Are peas high in calories?
No, most peas are low to moderate in calories. Green peas are about 117 kcal per cup raw, while snow and snap peas are even lower. Only dried split peas are calorie-dense, and that is because they are dehydrated.
Do peas lose calories when cooked?
Cooking does not destroy calories, but it changes the water content. Boiled peas absorb water, so a cup of cooked peas weighs more but contains fewer calories per gram than raw peas. The total calories in a given weight of dry peas remain the same.
Can I use this calculator for frozen peas?
Frozen peas are typically similar to raw or cooked peas in calorie content. If you thaw them and measure a cup, the values will be close to the raw or cooked figures. For best accuracy, use the cooked option if you boil them before eating.
Why do split peas have so many more calories?
Split peas are dried and have had most of their water removed. This concentrates the calories, protein, and carbohydrates. Once rehydrated by cooking, they become much less calorie-dense per cup.
