A fast-food hamburger has 257 to 506 calories and a cheeseburger 344 to 628, depending on the size of the patty, according to USDA data. A double cheeseburger runs 810 to 987. A quarter-pound cheeseburger made at home with ketchup comes to about 420 calories, and bacon and mayo push it near 600.

Key takeaways
Patty size and the number of patties set most of the calories.
A slice of cheese adds about 70 calories, two strips of bacon about 75 and a tablespoon of mayo about 95.
At the big chains, a single burger has about 360 to 580 calories and a double more than 600.
A veggie or turkey burger is not automatically lighter than a small beef burger.
Swapping the bun for lettuce saves about 140 to 150 calories.
How many calories are in a burger?
A single-patty burger on a bun has about 257 to 628 calories. Patty size matters most, then cheese. These are USDA averages for fast-food burgers with standard toppings.
Burger | Weight | Calories | Protein |
|---|---|---|---|
Slider | 2.5 oz (70 g) | 202 | 12 g |
Hamburger, small patty | 3.2 oz (90 g) | 257 | 14 g |
Hamburger, medium patty | 5.1 oz (145 g) | 418 | 25 g |
Hamburger, large patty | 6.2 oz (175 g) | 506 | 32 g |
Cheeseburger, small patty | 4.1 oz (115 g) | 344 | 19 g |
Cheeseburger, medium patty | 5.8 oz (165 g) | 488 | 29 g |
Cheeseburger, large patty | 7.4 oz (210 g) | 628 | 39 g |
Double cheeseburger, 2 medium patties | 9.5 oz (270 g) | 810 | 53 g |
Double cheeseburger, 2 large patties | 11.6 oz (330 g) | 987 | 67 g |
Turkey or chicken burger | 5.1 oz (145 g) | 339 | 29 g |
Veggie burger | 5.6 oz (160 g) | 358 | 21 g |
A veggie burger on a bun has more calories than a small beef burger, though less saturated fat. A turkey or chicken burger saves about 80 calories against a beef hamburger of the same weight.

Fast food burger calories
Chain burgers land in the same range as the USDA averages. Here are a few of the most ordered ones, from the chains' own nutrition pages:
Burger | Calories |
|---|---|
In-N-Out Hamburger, Protein Style (lettuce instead of bun) | 210 |
In-N-Out Hamburger | 360 |
In-N-Out Cheeseburger | 430 |
McDonald's Quarter Pounder with Cheese | 520 |
McDonald's Big Mac | 580 |
In-N-Out Double-Double | 610 |
The sauce makes a real difference. At In-N-Out, mustard and ketchup instead of the spread take 60 calories off any burger, and a lettuce wrap takes off 150.
Homemade burger calories, part by part
A homemade burger is easier to count because you know every part. Here is what each one adds, from USDA data:
Part | Calories |
|---|---|
Hamburger bun, 1.8 oz (52 g) | 139 |
Quarter-pound patty, 85% lean, cooked (2.7 oz, 77 g) | 193 |
American cheese, 1 slice (0.7 oz, 21 g) | 71 |
Bacon, 2 medium slices | 75 |
Mayonnaise, 1 tbsp | 94 |
Ketchup, 1 tbsp | 19 |
Bun, quarter-pound patty, cheese and ketchup add up to about 420 calories. Add bacon and mayo and you are near 600.
The beef you buy matters too. A 3 oz cooked patty has about 230 calories from 80% lean beef and 164 from 93% lean, a 66-calorie difference with almost the same protein.

Are burgers OK for weight loss?
Yes. A single cheeseburger has 344 to 628 calories, which fits in a calorie deficit like any other meal. The problems start with doubles, extra sauce and the fries and soda that come with them.
Saturated fat climbs fast. A medium fast-food cheeseburger has about 11 g, 57% of the 20 g Daily Value. A double with two large patties has about 27 g, more than a full day's worth, plus 1,350 mg of sodium.
To keep a burger lighter:
Order a single patty. Going from a double to a single saves 300 to 360 calories.
Skip the mayo or special sauce, or swap it for mustard and ketchup.
Try a lettuce wrap instead of the bun, or eat the burger open-faced.
Use 90% to 93% lean beef at home.
Pile on lettuce, tomato and onion for volume.
