A 3-ounce serving of steak (about the size of a deck of cards) contains between 145 and 290 calories, depending on the cut. Leaner cuts like sirloin and eye of round sit at the low end, while fattier cuts like ribeye and strip steak land closer to the top. The cut you choose, the grade of beef, and whether you trim visible fat all shift the number.
Calories by Cut
Not all steaks are created equal. A 3-ounce cooked serving of some of the most popular cuts breaks down like this:
- Eye of round: 170 calories
- Top sirloin: 145 to 200 calories
- Flank steak: 151 to 165 calories
- Top round: 180 calories
- Filet mignon (tenderloin): 165 to 220 calories
- Ribeye: 160 to 240 calories
- Top loin (strip steak): 290 calories
Those ranges exist because the same cut can vary based on USDA grade and how much fat is left on. The USDA numbers above reflect lean-only portions with external fat trimmed, which is why they tend to sit lower than what you’ll see on a restaurant menu where steaks are served with more fat intact.
Of course, most steaks you actually eat are larger than 3 ounces. A typical restaurant steak runs 8 to 12 ounces. An 8-ounce sirloin would contain roughly 390 to 530 calories, while an 8-ounce ribeye could reach 480 to 640 calories. To estimate your own portion, multiply the 3-ounce figure by how many 3-ounce increments your steak weighs.
How USDA Grades Affect Calories
The grade stamped on your beef tells you how much marbling (intramuscular fat) it contains, and that directly affects calorie count. USDA Select is the leanest grade commonly sold, Choice has moderate marbling, and Prime has the most. Most grocery store steak is Choice or Select. Prime is typically reserved for high-end restaurants and specialty butchers.
The calorie gap between grades is consistent across cuts. For a 3-ounce serving of ribeye, Select comes in at 160 calories while Choice hits 172. Sirloin shows a similar spread: 145 calories for Select versus 159 for Choice. Filet mignon goes from 165 (Select) to 175 (Choice). Prime would push each of those numbers higher still, though USDA data for Prime grades is less commonly published. As a rough rule, moving up one grade adds about 10 to 15 calories per 3-ounce serving for lean-only portions.
Does Trimming Fat Make a Difference?
You might assume that cutting the fat cap off your steak before cooking saves meaningful calories. The reality is more nuanced. Research from Agriculture and Agri-Food Canada tested ribeye steaks cooked with and without external fat and found no significant difference in calorie content between the two. The fat cap doesn’t appear to migrate into the lean meat during cooking the way many people expect.
That said, if you eat the fat cap itself, you’re adding calories. A thick rim of visible fat is calorie-dense, roughly 70 to 80 calories per tablespoon of rendered beef fat. So the savings come not from trimming before cooking, but from not eating the external fat on your plate.
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 translates to modestly fewer calories per serving, though the two are nutritionally similar overall. The more notable difference is in fat composition: grass-fed beef contains roughly twice the omega-3 fatty acids of grain-fed, though the total amount is still small (about 30 milligrams more per serving). If you’re choosing grass-fed for calorie reasons alone, the difference is marginal. Most of the calorie variation between any two steaks comes from the cut and grade, not the feeding method.
What Adds Calories Beyond the Steak
The steak itself is only part of the equation. Cooking in butter or oil adds 100 or more calories per tablespoon. A pat of compound butter melted on top adds another 70 to 100. Restaurant steaks are often basted in butter during cooking, which is one reason a steakhouse filet can clock in noticeably higher than the USDA baseline for that cut.
Marinades and sauces vary widely. A simple salt-and-pepper rub adds zero calories, while a sweet teriyaki or barbecue glaze can add 30 to 60 calories per serving. Cream-based sauces like béarnaise push that even higher. If you’re tracking closely, the cooking fat and finishing touches matter as much as the cut you pick.
Picking a Steak for Your Calorie Goals
If you want the lowest-calorie option, eye of round, top round, and top sirloin are your best bets, all coming in under 200 calories per 3-ounce serving even at Choice grade. Flank steak is another strong pick that also happens to be one of the more flavorful lean cuts. These work well for meal prep and stir-fries where you’re slicing the meat thin.
If you want a classic steakhouse experience without going overboard, filet mignon offers tenderness with moderate calories (165 to 220 per 3 ounces depending on grade and preparation). Ribeye and strip steak deliver the most flavor and marbling but sit at the top of the calorie range.
For a practical middle ground, choose a Select-grade sirloin or flank steak, season it simply, and cook it in a hot pan with a light coating of oil. A generous 6-ounce portion prepared this way lands around 300 to 350 calories, leaving plenty of room for sides.
