The short answer
A simple single burger with a regular bun, a modest beef patty, salad and a little ketchup is often somewhere around 300 to 500 calories. A restaurant burger with a larger patty, cheese, bacon and a creamy sauce commonly lands between 700 and 1,000 calories, and a double with all the extras can go higher. Fries and a sugary drink on the side can add as much again.
That range is not a reason to avoid burgers. It simply shows that the size of the patty and the extras matter far more than the word "burger". Once you know what each part typically adds, you can estimate almost any version with reasonable confidence.
Where the calories come from
The patty
The patty is usually the biggest single source of calories. Its size and fat content both matter. A small, thin patty of the kind served at many fast-food counters might be around 60 to 80 grams cooked. A thick restaurant patty is often closer to 150 grams or more. Beef mince with a higher fat percentage carries more calories per gram than lean mince, and some of that fat stays in the patty after cooking.
The bun
A standard sesame bun is often around 120 to 170 calories. Brioche buns are usually richer because of added butter, egg and sugar, and can reach 200 calories or more. A lettuce wrap swaps the bun for almost nothing, while a pretzel or ciabatta-style bun tends to be heavier.
Cheese and bacon
A single slice of processed cheese is often around 60 calories, while a thicker slice of cheddar can be closer to 80 to 120. Two rashers of bacon typically add around 80 to 120 calories, depending on how crisp and how fatty they are.
Sauces
Sauces are easy to underestimate because they do not take up much space. A tablespoon of mayonnaise or a creamy burger sauce is often around 90 to 100 calories. Ketchup and mustard are much lighter, at roughly 15 to 20 calories and under 10 calories per tablespoon respectively. A burger with a generous layer of sauce on both halves of the bun can easily carry 150 to 200 calories from sauce alone.
| Component | Typical portion | Approx. calories |
|---|---|---|
| Thin beef patty | about 70 g cooked | 170–220 |
| Thick beef patty | about 150 g cooked | 350–450 |
| Plant-based patty | about 110 g | 200–280 |
| Grilled chicken fillet | about 120 g | 160–200 |
| Regular bun | 1 bun | 120–170 |
| Brioche bun | 1 bun | 180–250 |
| Processed cheese | 1 slice | about 60 |
| Bacon | 2 rashers | 80–120 |
| Mayonnaise or burger sauce | 1 tablespoon | 90–100 |
| Ketchup | 1 tablespoon | 15–20 |
| Lettuce, tomato, onion, pickles | a typical serving | 10–25 |
Three example burgers
- Simple: regular bun, thin patty, ketchup, pickles and onion. Roughly 300 to 400 calories.
- Classic cheeseburger: regular bun, thick patty, one slice of cheese, salad and a tablespoon of sauce. Roughly 650 to 800 calories.
- Stacked double: brioche bun, two thick patties, two slices of cheese, bacon and plenty of sauce. Roughly 1,100 calories or more.
Do not forget the sides
The burger is often only part of the meal. A medium portion of fries is commonly around 300 to 450 calories, onion rings are similar or higher, and a regular sugary soft drink adds roughly 150 to 250 calories with very little fullness. A side salad, a smaller portion of fries, or water or a sugar-free drink can make the overall meal noticeably lighter without giving up the burger itself.
Making a burger more filling for the calories
If you enjoy burgers regularly and are watching your intake, a few small swaps go a long way:
- Choose a single patty and add extra salad, tomato and onion for volume.
- Pick one rich extra rather than all of them: cheese or bacon or a creamy sauce.
- Ask for sauce on the side so you can decide how much to use.
- Try a grilled chicken or lean beef option, which keeps the protein while trimming some fat.
- Share a portion of fries, or pair the burger with a side salad.
Homemade burgers give you the most control. Using lean mince, a regular bun and plenty of salad is an easy way to make a satisfying meal that still feels like a treat.
Estimating a burger you did not make
When you eat out, look at the height of the patty compared with the bun, whether there is more than one patty, and how much sauce is visible at the edges. A patty about as thick as your thumb and as wide as the bun is usually on the larger side.

Frequently asked questions
How many calories are in a plain hamburger?
A simple hamburger with a regular bun, a thin beef patty and ketchup is typically around 250 to 350 calories. Larger patties, cheese, bacon and creamy sauces push the total higher.
Is a burger without the bun much lighter?
Removing a regular bun usually saves around 120 to 170 calories, and more for a brioche bun. The patty, cheese and sauces stay the same, so they still make up most of the total.
Are plant-based burgers lower in calories?
Not always. Many plant-based patties have similar calories to a beef patty of the same size. Check the label or menu information if you want to compare a specific product.
