A 3-ounce serving of cooked steak contains roughly 160 to 250 calories, depending on the cut. That’s a piece about the size of a deck of cards. Most steaks served at restaurants weigh 8 to 12 ounces, which means a typical dinner steak lands somewhere between 400 and 1,000 calories before any sides or sauces.
Calories by Cut
The biggest factor in steak calories is the cut itself, specifically how much fat runs through the meat (the marbling). A 3-ounce serving of broiled ribeye comes in at about 199 calories, according to USDA data. Ribeye is one of the fattier cuts, prized for flavor but higher in calories per ounce.
Leaner cuts drop the calorie count significantly. Bottom round steak, for example, has only about 4 grams of fat per 100 grams of raw meat compared to 17 grams in short ribs. That difference alone accounts for over 100 calories per serving. Here’s a general breakdown for a 3-ounce cooked portion:
- Ribeye: ~200 calories
- New York strip: ~180 calories
- Sirloin: ~160–180 calories
- Tenderloin (filet mignon): ~170–190 calories
- Flank steak: ~160 calories
- Eye of round: ~140–150 calories
The pattern is straightforward: the more marbling, the more calories. Cuts from the loin and round (the back and rear leg of the cow) tend to be leaner. Cuts from the rib section carry more intramuscular fat.
Why Serving Size Matters More Than the Cut
The USDA considers a single serving of meat to be 2 to 3 ounces cooked. A 12-ounce steak, the kind commonly served at steakhouses, is essentially four servings in one plate. That means a 12-ounce ribeye approaches 800 calories from the steak alone, while a 12-ounce sirloin sits closer to 640.
If you’re tracking calories, the most important thing you can do is weigh or estimate the actual size of the steak you’re eating. The difference between a 6-ounce and a 10-ounce portion is often 150 to 250 calories, which dwarfs the difference between choosing a ribeye over a sirloin.
Protein and Fat in Steak
Steak is almost entirely protein and fat with zero carbohydrates. A lean cut like bottom round delivers about 22 grams of protein and only 4 grams of fat per 100 grams raw. A fattier cut like boneless short ribs provides around 18 grams of protein and 17 grams of fat for the same weight. The protein stays fairly consistent across cuts; it’s the fat content that drives the calorie swing.
Each gram of fat contains 9 calories, more than double the 4 calories per gram of protein. So when a cut has an extra 13 grams of fat, that alone adds about 117 calories. This is why heavily marbled steaks taste richer but cost more from a calorie perspective.
How Steak Compares to Other Proteins
Steak sits in the middle of the pack among common animal proteins. A 3-ounce portion of lean beef has about 196 calories, nearly identical to a 4-ounce chicken breast at 198 calories and pork at 202 calories for 3 ounces. Tuna is noticeably leaner at 111 calories for 3 ounces, while salmon runs slightly higher at about 210 calories per 100 grams.
The practical takeaway: lean steak is not dramatically more caloric than chicken breast. The reputation steak has as a high-calorie food comes from portion sizes and cut selection, not from beef being inherently calorie-dense.
Raw Weight vs. Cooked Weight
Steak loses water during cooking, which means a raw steak and the same steak after cooking will weigh different amounts but contain the same calories. A 225-gram raw tenderloin with 320 calories might lose 50 grams of water on the grill, but the cooked steak still has 320 calories in it, just packed into a smaller, denser piece of meat.
This trips people up when tracking calories. If you weigh your steak after cooking and look up the raw nutrition data, you’ll undercount. A cooked steak weighing 175 grams doesn’t have the same calories as 175 grams of raw steak. It has the calories of the original 225-gram raw piece. Most nutrition databases specify whether values are for raw or cooked meat, so check that label carefully. The safest approach is to weigh your steak raw, before it hits the pan.
Cooking Method and Added Calories
Grilling or broiling a steak adds virtually no calories since the meat cooks in its own rendered fat, much of which drips away. Pan-searing in butter or oil does add some, but less than you might think. A tablespoon of butter is about 100 calories, but most of it stays in the pan rather than absorbing into the meat. With fattier cuts, the steak actually loses more fat through rendering than it absorbs from the cooking oil, sometimes resulting in a net calorie decrease compared to the raw numbers.
For leaner cuts cooked in oil, a reasonable estimate is to add 30 to 50 calories for the small amount of fat absorbed during searing. If you’re basting a steak in butter, adding 50 to 80 calories to your count is a practical estimate. These numbers are small relative to the 400 to 800 calories in the steak itself.
Grass-Fed vs. Grain-Fed
Grass-fed beef is slightly leaner than grain-fed because grass-fed cattle take longer to reach market weight and develop less marbling. This means grass-fed steaks tend to be modestly lower in calories, though the difference per serving is small. Grass-fed beef also contains about twice the omega-3 fatty acids of grain-fed, though the absolute amount is still low (roughly 30 milligrams more). For calorie-counting purposes, the difference between grass-fed and grain-fed is far less significant than the difference between cuts or portion sizes.
