A standard 3-ounce serving of cooked steak contains roughly 150 to 250 calories, depending on the cut and how much fat it carries. That 3-ounce portion, about the size of a deck of cards, is what the USDA considers one serving of cooked beef. You’ll need about 4 ounces of raw steak to end up with 3 ounces after cooking, since meat loses moisture and shrinks during the process.
Calories by Cut
The cut you choose is the single biggest factor in how many calories end up on your plate. Leaner cuts pull from parts of the animal that do less marbling, while fattier cuts come from well-marbled sections near the ribs and belly. Here’s how popular cuts compare for a 3-ounce cooked serving:
- Eye of round: Around 140 to 150 calories. One of the leanest cuts available.
- Top sirloin: Around 160 to 180 calories. A solid middle ground between flavor and leanness.
- Filet mignon (tenderloin): Around 170 to 200 calories. Tender but relatively lean for a premium cut.
- Ribeye (lean only, trimmed): Around 150 calories when all visible fat is removed. Left untrimmed with its natural fat cap, a ribeye easily reaches 230 to 250 calories per serving.
- T-bone or porterhouse: Around 200 to 250 calories, depending on how much strip and tenderloin each piece contains.
The gap between a lean cut and a fatty one can be over 100 calories per serving. If you’re tracking intake closely, trimming visible fat before or after cooking makes a measurable difference.
How USDA Grade Affects Calories
Beef sold in the U.S. is graded by the USDA based on marbling, which is the white streaks of fat running through the muscle. Prime beef has the most marbling, followed by Choice, then Select. More marbling means more intramuscular fat, which directly adds calories even if the cut looks the same size.
A Prime ribeye will have noticeably more calories than a Select ribeye of the same weight. The difference can range from 20 to 50 extra calories per 3-ounce serving, purely from the additional fat woven into the meat. Most grocery stores carry Choice grade, while Prime is more common at steakhouses and specialty butchers. Select is the leanest option and often the most affordable.
Protein, Fat, and Other Nutrition
Steak is primarily protein and fat with zero carbohydrates. A 3-ounce serving of broiled ribeye delivers about 24 grams of protein and roughly 11 grams of total fat. Of that fat, about 4.2 grams is saturated, 4.4 grams is monounsaturated, and a small amount is polyunsaturated. Leaner cuts like sirloin shift that ratio, dropping total fat to around 5 to 7 grams while keeping protein in the same 24 to 26 gram range.
Beyond the macronutrients, steak is unusually rich in a few key micronutrients. A single serving qualifies as an “excellent source” of vitamin B12, delivering over 60% of the daily value. It’s also an excellent source of zinc, covering roughly 20 to 25% of daily needs. Iron content is more modest at around 7 to 9% of the daily value per serving, but the form of iron in red meat (called heme iron) is absorbed significantly more efficiently by your body than the iron found in plant foods.
What Cooking Adds to the Count
The steak itself is only part of the calorie picture. How you cook it matters too. Grilling or broiling without added fat keeps the calorie count closest to the raw numbers. Pan-searing in oil or butter, which is how many people cook steak at home, adds calories from the cooking fat.
One tablespoon of olive oil adds about 120 calories. Butter is slightly less, around 100 calories per tablespoon, because about 20% of butter is water and milk solids rather than pure fat. Not all of that fat ends up absorbed into the meat, some stays in the pan, but a reasonable estimate is that pan-searing adds 50 to 80 calories per steak depending on how much fat you use and how much the meat soaks up. Finishing with a pat of butter on top (a common restaurant move) adds another 35 to 50 calories.
Restaurant Portions vs. Actual Servings
The 3-ounce USDA serving size rarely matches what you’ll find on a plate when dining out. A typical restaurant steak ranges from 8 to 16 ounces before cooking. An 8-ounce raw steak yields roughly 6 ounces cooked, which is two USDA servings. A 16-ounce ribeye is more than five servings. That means a restaurant steak can easily contain 400 to 1,000 calories from the meat alone, before any sides, sauces, or butter.
If you’re cooking at home and want to stay close to a single serving, weigh your steak after cooking and aim for about 85 grams, or just under 3 ounces. A kitchen scale takes the guesswork out of it. Without a scale, picture a piece roughly the size and thickness of your palm (not including fingers).
