A standard quarter-pound beef burger patty (80% lean, 20% fat) contains about 204 calories after cooking. That number shifts significantly depending on the fat content of the meat, the size of the patty, and whether you’re using beef, bison, or a plant-based alternative.
Calories by Fat Content
The lean-to-fat ratio of your ground beef is the single biggest factor in how many calories your patty contains. For a cooked quarter-pound patty, here’s what to expect:
- 70/30 (70% lean): roughly 230 to 250 calories
- 80/20 (80% lean): about 204 calories
- 90/10 (90% lean): roughly 170 to 180 calories
- 93/7 (93% lean): roughly 150 to 160 calories
Each 10-point jump in fat percentage adds around 25 to 40 calories per patty. The fattier grinds taste juicier because fat carries flavor, so there’s a real trade-off between calories and taste. If you’re watching your intake closely, swapping from 80/20 to 90/10 saves you about 30 calories per patty without a dramatic change in texture.
Calories by Patty Size
Quarter-pound patties are the default at most restaurants and in most grocery store packs, but plenty of burgers are bigger. Using 80/20 ground beef as the baseline:
- Quarter pound (4 oz raw): ~204 calories cooked
- Third pound (5.3 oz raw): ~270 calories cooked
- Half pound (8 oz raw): ~408 calories cooked
These are for the patty alone, with no bun, cheese, or toppings. A half-pound burger from a restaurant can easily exceed 400 calories before anything else hits the plate. Fast-food chains often use smaller patties in the 2 to 3 oz range, which land closer to 100 to 150 calories each, though doubles and triples obviously multiply that.
How Cooking Changes the Numbers
Raw and cooked calorie counts aren’t the same, and it’s worth understanding why. When you grill or pan-fry a burger, fat renders out and drips away. A quarter-pound raw patty weighs 4 ounces before cooking but typically shrinks to around 3 ounces afterward. Some of the original fat calories leave with that rendered grease.
This is why a 4-ounce raw 80/20 patty starts at roughly 280 calories but yields a cooked patty closer to 204 calories. The fattier the meat, the more it shrinks and the more calories it loses during cooking. A 70/30 patty will lose more weight (and more fat) than a 93/7 patty, which narrows the calorie gap between them slightly once they’re on your plate. Grilling tends to drain more fat than pan-frying because the grease falls through the grates rather than pooling around the patty.
Plant-Based Burger Patties
If you assumed plant-based patties were lower in calories, the reality might surprise you. A 4-ounce Impossible Burger patty has 240 calories and 14 grams of fat. A 4-ounce Beyond Burger patty comes in at 230 calories and 18 grams of fat. Both contain around 19 to 20 grams of protein.
That puts them roughly on par with, or slightly above, a standard 80/20 beef patty in terms of calories. The nutritional advantage of plant-based patties isn’t really about calorie reduction. It’s more about environmental impact and avoiding animal products. If your goal is fewer calories, a lean beef patty (90/10 or 93/7) will actually come in lower than either plant-based option.
Bison and Other Lean Alternatives
Game meats offer a genuinely lower-calorie option. A 3.5-ounce serving of cooked bison contains about 142 calories, compared to roughly 282 calories for the same amount of cooked beef. That’s nearly half the calories, largely because bison is naturally much leaner than most commercial beef.
Venison, elk, and turkey patties fall in a similar range to bison, typically 140 to 180 calories for a cooked quarter-pound patty. Turkey burgers specifically tend to run around 170 calories for a 4-ounce cooked patty made from 93% lean ground turkey. These alternatives do cook differently than beef. Less fat means they dry out faster, so shorter cooking times or added moisture (like a splash of Worcestershire sauce mixed into the meat) helps.
What the Toppings Add
The patty is often the least calorie-dense part of a fully assembled burger. A standard white hamburger bun adds 120 to 150 calories. A slice of American cheese adds about 70 calories. A tablespoon of mayonnaise adds 90 to 100 calories. Ketchup and mustard are relatively light at 15 to 20 calories per tablespoon, but special sauces can add 50 to 80 calories per serving.
A basic cheeseburger with a bun, one slice of cheese, and condiments typically lands between 400 and 500 total calories. A loaded half-pound burger with bacon, extra cheese, and sauce can push past 900. If you’re tracking calories, the patty itself is a useful starting point, but the full picture depends heavily on how you dress it.
