When you track your daily intake, knowing the exact number of calories in 100g of cooked rice is essential. A standard 100g serving of cooked white rice contains roughly 130 calories, but that number shifts based on the grain variety, your cooking method, and whether the rice is measured dry or cooked.
Understanding these differences keeps your meal planning accurate. Whether you're bulking, cutting, or just trying to balance your plate, here's everything you need to know about the energy content of different rice varieties and how preparation changes the numbers.
Raw vs. Cooked Rice: The Most Common Mistake
The biggest trap when counting calories in rice is mixing up raw and cooked weights. Rice absorbs a massive amount of water during the boiling process, which expands its total weight and drastically drops its calorie density per gram.
- Raw (Dry) Rice: 100g of dry white rice contains about 360 to 370 calories. Because raw grains are dehydrated, they pack a dense punch of carbohydrates.
- Cooked Rice: 100g of cooked white rice contains about 130 calories. The water absorbed during cooking makes up the difference in weight without adding any extra energy.
If you weigh your rice after it's cooked, use the cooked metric. If you weigh it raw before tossing it into the rice cooker, use the dry metric. Getting this backward will throw off your macro tracking by a factor of nearly three.
Calorie Breakdown by Rice Variety
Not all grains are created equal. While the differences aren't massive, switching from white jasmine to whole grain brown rice changes your fiber intake and micronutrients. Here is what 100g of cooked rice yields across popular varieties:
White Rice (Long-Grain and Medium-Grain)
Standard long-grain white rice sits right around 130 calories per 100g cooked. Because the milling process strips away the outer bran and germ, white rice digests quickly, making it a favorite for post-workout glycogen replenishment.
Brown Rice
Brown rice contains about 111 calories per 100g cooked. Even though it retains the fiber-rich bran layer, it holds onto more water during cooking than white rice does, which explains why its calorie count per 100g of cooked weight is slightly lower than white rice. It provides a slower, more sustained release of energy.
Basmati Rice
Cooked basmati rice delivers roughly 121 calories per 100g. Known for its aromatic nutty scent and slender grains, basmati has a lower glycemic index than most other white rices, meaning it causes a slower rise in blood sugar.
Jasmine Rice
Jasmine rice runs about 129 calories per 100g cooked. This fragrant Thai variety has a slightly stickier texture than basmati and shares a similar nutritional profile to standard long-grain white rice.
Wild Rice
Technically not a true rice but the seed of an aquatic marsh grass, wild rice is lower in calories at roughly 101 calories per 100g cooked. It also packs significantly more protein than standard white or brown varieties.
How Cooking Methods Change the Math
The way you prepare your grain alters its final calorie count. Simple boiling or steaming keeps things straightforward, but adding fats changes the equation entirely.
Steaming and Boiling
Standard water-absorption cooking methods don't add calories. However, if you use bone broth, vegetable stock, or coconut milk instead of plain water, you must account for the fats and calories in the liquid. Cooking rice in full-fat coconut milk can easily push a 100g serving past 200 calories.
Frying
Making fried rice requires oil or butter. Even a modest tablespoon of cooking oil adds over 100 calories to the pan. If you're tracking strictly, measure your fats before tossing leftover rice into the skillet.
Resistant Starch: A Trick to Lower Usable Calories
Recent food science highlights an interesting quirk about how our bodies process starches: cooling cooked rice changes its molecular structure.
When you cook rice and then let it cool in the refrigerator for at least 12 to 24 hours, some of the digestible starches turn into resistant starch. Your body treats resistant starch more like dietary fiber, meaning it resists being broken down in the small intestine. This lowers the net digestible calories you absorb from the meal and feeds beneficial gut bacteria. Reheating the rice doesn't reverse this change entirely, making cold or reheated leftover rice a smart trick for blood sugar management.

Frequently Asked Questions
Does washing rice change its calorie count?
Rinsing raw rice removes excess surface starch and powdery residue, but it doesn't change the internal calories of the grain. The difference is negligible for daily tracking.
Is brown rice always better than white rice?
Not necessarily. While brown rice offers more fiber, magnesium, and B vitamins, white rice is easier on sensitive stomachs and digests faster. Choose the one that fits your digestion and lifestyle.
Why does my cooked rice weight vary so much?
Rice absorbs water differently depending on the cooking time, grain age, and water ratio. If you add too much water, the rice becomes mushy and heavier per gram, lowering the calorie density of that specific batch. For precise tracking, stick to a consistent water-to-grain ratio every time you cook.
How long does cooked rice stay safe to eat?
Cooked rice can harbor Bacillus cereus, a bacterium that produces spores resistant to heat. Store cooked rice in the refrigerator within an hour of cooking and consume it within three to four days. For food safety guidelines, check the U.S. Food and Drug Administration.
