Scale to GramsHow Many Calories in a Burger? By Type, Size & Toppings
Basic Burger Calorie Math
A burger is a sum of its parts, and understanding each component makes calorie estimation straightforward. A standard hamburger bun has 120-150 calories. A quarter-pound (113g raw) beef patty has about 280 calories after cooking. A slice of American cheese adds 70 calories. Ketchup adds 15-20 calories per tablespoon. Mustard adds only 3-5 calories. Mayonnaise adds 90-100 calories per tablespoon — this is the sneaky calorie bomb. Lettuce, tomato, and onion combined add only about 10-15 calories. So a basic burger with a bun, patty, ketchup, and vegetables comes to roughly 350-380 calories. Add cheese and you hit 420-450. Add mayo and you are at 540-550. Each additional component has a predictable calorie cost.
Calories by Patty Size
The patty is the biggest calorie variable. Ground beef (80/20 lean-to-fat ratio) contains about 250 calories per 100 grams raw, which drops to about 230 calories per 100 grams cooked as some fat renders out. A thin fast-food patty (45g cooked, like McDonald's regular hamburger) has about 100 calories. A standard quarter-pounder patty (113g raw, about 85g cooked) has about 200 calories. A thick restaurant patty (170g raw, about 130g cooked) has about 300 calories. A half-pound monster patty (225g raw) has about 400 calories. Double patties simply double the meat calories. Leaner beef (90/10) cuts about 30% of the fat calories — a quarter-pound 90/10 patty has about 155 calories instead of 200.
Fast Food Burger Calories
Major chains publish their nutrition data, so these numbers are exact. A McDonald's Hamburger has 250 calories. A McDonald's Big Mac has 550 calories. A Burger King Whopper has 660 calories (without cheese) or 740 with cheese. A Wendy's Dave's Single has 590 calories. A Five Guys Little Hamburger has 480 calories. A Five Guys regular hamburger (two patties) has 700 calories — and that is before fries. An In-N-Out Double-Double has 670 calories. A Shake Shack ShackBurger has 530 calories. The calorie range across fast food burgers spans from 250 (basic small hamburger) to over 1,000 (large double-patty with bacon and special sauces). The single biggest calorie driver at fast food restaurants is portion size, followed by sauce quantity.
High-Calorie Toppings to Watch
Some toppings add more calories than the patty itself. Bacon adds 80-120 calories per 2-3 strips. A fried egg adds 90 calories. Avocado or guacamole adds 60-80 calories per serving. Fried onion rings as a topping add 100-150 calories. Special sauces (burger sauce, "secret sauce," aioli) are typically mayo-based and add 100-150 calories per generous serving. Extra cheese adds another 70-110 calories per slice. Barbecue sauce adds 30-50 calories per tablespoon. The difference between a "basic" burger and a "fully loaded" burger at the same restaurant can easily be 400-600 calories — equivalent to an entire additional meal.
Lower-Calorie Burger Strategies
You do not have to give up burgers to manage calories. Choosing a thinner patty or a single instead of double saves 100-200 calories instantly. Skipping the top bun (eating it open-faced) or using a lettuce wrap eliminates 60-75 calories. Asking for mustard instead of mayo saves 85-95 calories. Skipping cheese saves 70-110 calories per slice. Choosing grilled onions over fried saves 80-100 calories. Turkey or chicken burgers save about 50-80 calories versus beef at the same portion size. Veggie or plant-based patties (Impossible, Beyond) have similar calories to beef but different macros — they are not automatically lower-calorie. The most impactful single change is controlling sauce quantity, since that is where hidden calories accumulate fastest.
Estimating Burger Calories Without Nutrition Info
When eating at a local restaurant without published nutrition data, estimate by building up from components. Assess the patty size — compare it to your palm. A palm-sized patty is roughly a quarter pound (200 cal). Thicker than your palm is closer to a third or half pound (250-400 cal). Add the bun (130 cal), visible cheese (70 cal per slice), and estimate sauce volume — a light spread is 1 tablespoon (50-100 cal depending on type), a generous slathering is 2-3 tablespoons (100-300 cal). You can also photograph the burger and use Scale to Grams to get an AI calorie estimate — the tool identifies the components, estimates portions, and calculates total calories and macros in seconds.
