Rice is a staple for billions of people, but its protein content varies widely depending on the type and how it's prepared. This calculator helps you quickly determine the protein in any rice variety per 100 grams, whether you're tracking macros, planning a vegetarian diet, or just curious about your favorite grain.
Simply select the rice type (white, brown, basmati, jasmine, wild, or cooked), enter the amount you're eating, and get an instant protein estimate. You can also adjust for cooked versus dry weight, since rice absorbs water and changes its protein density. Perfect for meal prep, fitness tracking, and balanced nutrition planning.
Use the quick-fill buttons to load common serving sizes, or type in your own values. The result includes a breakdown per 100g and for your total portion, so you can log your intake with confidence.

How to Use This Tool
Select your rice type from the dropdown — we've included the most common varieties: white, brown, basmati, jasmine, and wild rice, each available in both cooked and dry (uncooked) forms. Then enter the amount you're eating. You can specify grams, ounces, or cups (for cooked rice). The calculator converts everything to grams and applies the appropriate protein density.
For the most accurate results, use the cooked option when measuring cooked rice, and the dry option when measuring uncooked rice. If you're logging a recipe, remember that 1 cup of dry rice yields about 3 cups cooked, so adjust accordingly.
How It Works
The protein content is based on standard USDA FoodData Central values. For cooked rice, we use the average protein per 100g after cooking (which includes water absorption). For dry rice, we use the raw grain values. The calculator multiplies your portion weight (in grams) by the protein density to get total protein.
For example, if you eat 150g of cooked brown rice, the calculation is: (150 / 100) × 2.6 = 3.9g protein. If you eat 100g of dry wild rice, you get (100 / 100) × 14.7 = 14.7g protein — a significant difference because dry rice is much denser.
Worked Examples
Example 1: You cook 1 cup of white rice (about 158g cooked). Select "White Rice (cooked)", enter 158g. Protein = 1.58 × 2.7 = 4.3g.
Example 2: You're meal-prepping with 200g of dry basmati rice. Select "Basmati Rice (dry)", enter 200g. Protein = 2.0 × 8.0 = 16.0g.
Example 3: You have a 6-ounce serving of cooked jasmine rice. Convert to grams: 6 × 28.35 = 170.1g. Protein = 1.701 × 2.7 = 4.6g.
Tips & Best Practices
- Always weigh rice in its current state (cooked or dry) — don't mix them up.
- For tracking macros, use a food scale for accuracy; volume measurements can vary.
- Brown rice and wild rice have slightly more protein than white, but the difference is modest.
- If you're adding rice to a mixed dish, calculate the protein for the rice portion separately.
Factors Affecting Accuracy
Protein values can vary by brand, growing conditions, and cooking method. The values used here are averages from USDA data. If you're using a specific brand, check the nutrition label for the most precise number. Also, the cup-to-gram conversion for cooked rice assumes a standard cooked texture; if your rice is very dry or very moist, the weight per cup will differ.
Frequently Asked Questions
Is rice a good source of protein? Rice provides some protein, but it's not a complete protein (it lacks lysine). Pair it with beans, lentils, or animal products to get all essential amino acids.
Why does dry rice have more protein per 100g? Because dry rice has no water weight. When cooked, rice absorbs water and the protein becomes diluted per gram.
Can I use this for rice flour? No, this calculator is for whole rice grains. Rice flour has a different protein content (around 6-7g per 100g).
How much protein do I need daily? The general recommendation is 0.8g per kg of body weight, but athletes and older adults may need more. Use this calculator to see how rice contributes to your daily intake.
