Edamame—young soybeans still in the pod—is one of the most fiber-dense legumes you can snack on. A 100-gram serving of cooked, shelled edamame delivers about 5.2 grams of dietary fiber, along with plant protein, folate, vitamin K, and magnesium. This calculator converts your serving size from grams, ounces, or cups into the exact fiber content you'll get, plus the percentage of the Daily Value (28 grams for a 2,000-calorie diet).
Whether you're meal prepping a high-fiber lunch, adding edamame to salads and grain bowls, or tracking macros for gut health and weight management, this tool keeps the numbers consistent. It also shows how fiber-related details like net carbs and protein change with your portion, so you can plan meals with confidence.

How to Use This Tool
This calculator is designed for shelled edamame that has been cooked or steamed, which is how most people eat it. Enter the amount in grams, ounces, or cups, then press Calculate Fiber. One US measuring cup of shelled edamame weighs about 155 grams, and one ounce equals 28.35 grams. If you prefer to weigh your snack in your kitchen, grams gives the most precise result.
Fiber Reference: Edamame at a Glance
The table below shows typical values for cooked, shelled edamame based on USDA data. These are averages; brands and cooking methods may shift the numbers slightly.
| Serving | Weight | Fiber | Protein | Net Carbs | Calories |
|---|---|---|---|---|---|
| 1 oz | 28 g | 1.5 g | 3.4 g | 1.0 g | 34 |
| 3 oz | 85 g | 4.4 g | 10.1 g | 3.1 g | 104 |
| 1/2 cup | 78 g | 4.0 g | 9.2 g | 2.9 g | 94 |
| 1 cup | 155 g | 8.1 g | 18.4 g | 5.8 g | 188 |
| 100 g | 100 g | 5.2 g | 11.9 g | 3.7 g | 121 |
Net carbs are total carbohydrates minus fiber. Since fiber is not digested like other carbs, many low-carb and blood-sugar-conscious eaters track net carbs instead of total carbs.
The Math Behind It
Every calculation uses the same simple proportion:
Fiber (g) = serving weight (g) × 5.2 g / 100 g
The 5.2 g per 100 g value comes from USDA FoodData Central entries for cooked, frozen edamame. To get the Daily Value percentage, divide the fiber result by 28 g — the reference amount used on Nutrition Facts labels for a 2,000-calorie diet — and multiply by 100.
For example, a 155-gram cup gives 155 × 0.052 = 8.06 g of fiber. That is 8.06 ÷ 28 × 100 = 29% of the Daily Value. The same proportion is used for protein (11.9 g per 100 g), total carbohydrates (8.9 g per 100 g), and calories (121 kcal per 100 g).
For official nutrition data, see USDA FoodData Central. The 28 g Daily Value reference is from the FDA nutrition labeling guidance.
Worked Examples
Example 1: A 1-cup edamame snack. 155 g × 0.052 = 8.1 g fiber, which is 29% DV. The same serving gives about 18.4 g protein, 5.8 g net carbs, and 188 kcal.
Example 2: A 3-oz side dish. 85 g × 0.052 = 4.4 g fiber, which is 16% DV. Net carbs are about 3.1 g, making it a lower-carb legume side.
Example 3: 200 g in a stir-fry. 200 g × 0.052 = 10.4 g fiber, which is 37% DV. This is more than a third of your daily fiber target from one portion.
Tips & Best Practices
Weigh edamame shelled, after cooking, for the most accurate numbers. If you bought frozen edamame in bags, the nutrition panel already refers to shelled beans after preparation, so the calculator matches those values closely.
Add edamame to salads, rice bowls, soups, and hummus-style spreads. A half-cup portion alone provides about 4 g of fiber, which makes it easy to reach the 28 g daily target.
If you are weighing edamame still in the pod, remember that pods are not usually eaten and account for a large share of the total weight. Use the shelled weight for accurate fiber and calorie calculations. Also, if you are not used to high-fiber foods, increase your portion gradually and drink plenty of water.
Common Questions
Is edamame a good source of fiber?
Yes. At around 5.2 g per 100 g, edamame has more fiber per serving than most cooked vegetables and comparable fiber to many beans, with the bonus of complete soy protein.
Does cooking change the fiber content?
Fiber is stable during normal boiling or steaming, so the value stays roughly the same. Adding salt or seasoning does not significantly affect fiber either.
Can I use this calculator for frozen edamame?
Yes. Frozen prepared edamame has essentially the same fiber density as freshly cooked shelled edamame. If the package label lists a different fiber value, you can adjust by using the per-100g proportion above.
What if I only have a nutrition label?
This calculator is based on USDA averages. For packaged edamame, use the label's fiber per 100 g or per serving and multiply by your serving weight in grams.
