How many calories in ground beef? By fat percentage, raw and cooked

Ground beef is where the raw-versus-cooked problem does the most damage in a food diary. The pack says one thing, the pan says another, and the fat that ends up down the sink is somewhere between 0 and 250 calories depending on what you bought.

Here is what it actually costs, by fat percentage, raw and cooked, drained and undrained.

The quick answer

80% lean ground beef is about 254 kcal per 100g raw. 95% lean is about 137 kcal. That is an 85% difference from the same shelf, driven entirely by the fat percentage on the label. USDA reference data is consistent across the range.

US packs are labelled by lean percentage (80/20, 90/10). UK packs are labelled by fat percentage (20% fat, 10% fat, 5% fat). They describe exactly the same thing from opposite ends.

Raw and cooked in one table

This is the part that trips everyone up. Cooking removes water and, in fattier mince, some rendered fat. So the per-100g figure goes up while the weight of what is in the pan goes down.

Read the last column. Browning 100g of raw 80/20 and pouring the fat off leaves you eating about 180 kcal rather than 254. That difference, roughly 74 kcal per 100g, is the fat in the pan.

For 5% mince the same operation saves about 10 kcal, because there is nothing to pour off.

Which weight should you log?

Raw, when you can. Cooked weight depends on the pan temperature, how long it sat, whether it was covered and how hard you pressed it. Raw weight depends on nothing.

The practical rules:

1. Weigh the pack, cook it all, then divide by portions. For mince this beats weighing your own plate, because mince cannot be portioned by eye once it is in a sauce.
2. If you only have a cooked figure, divide by 0.73 to estimate the raw weight. 150g cooked is roughly 205g raw.
3. Match the entry to the weight. Logging 150g of cooked mince against a raw database entry underestimates by around 20%. Logging raw weight against a cooked entry overestimates by the same margin.
4. Decide once whether you drain. If you always drain, use the drained figure every time. Inconsistency costs more accuracy than either choice.

(For the same problem on the carb side of the plate, the rice calorie breakdown and the pasta calorie breakdown cover dry-versus-cooked weights.)

Beef against every other mince

The turkey line is worth sitting with. "Swapping to turkey mince" only saves calories if the turkey is leaner than the beef it replaced. Standard 85/15 ground turkey is within 2 kcal of 85/15 ground beef. The lean percentage is doing all the work, and the animal on the label is doing almost none.

(For the same argument on chicken cuts, the chicken breast calorie breakdown covers breast versus thigh.)

The dishes people actually make

Per portion, assuming four portions from a 500g pack.

The pattern is flat and useful: about 145 kcal per portion, every time, from one decision made in the shop. Over a week of two mince dinners that is around 290 kcal, and it requires no change to how you cook.

The trade-off is real. Twenty percent mince browns better, tastes richer and holds together in a burger. Five percent mince can go dry and grainy in a fast fry. The middle option, 10 to 12% fat, keeps most of the flavour for about 60 kcal per 100g less than standard.

Burgers, where the fat matters most

A burger is the one format where lean mince genuinely behaves differently, because there is no sauce to carry it.

Grilling drops more fat than pan frying, because it drips away rather than sitting in the pan. That is why the cooked figures here are lower than the raw ones even before anything is drained.

Is mince a good protein source?

At the lean end, yes. At the fatty end it is a fat source with protein attached.

Extra lean mince at 17g per 100 kcal is in the same conversation as chicken breast. Standard 80/20 at 7g is closer to cheese. Same food, same aisle, very different roles in a day.

Beef also carries iron, zinc and B12 in forms the body absorbs easily, which lentils and most meat substitutes do not match. And the total protein you are aiming for matters more than the source: the 2018 meta-analysis by Morton and colleagues found total daily protein intake, not any single food, drove gains in lean mass alongside training.

Ground beef mistakes to avoid

Logging cooked weight against a raw entry

The most common mince error and worth about 20%. 100g raw becomes roughly 73g cooked, so 150g on your plate came from about 205g in the pack.

Not accounting for the fat you did not drain

Browning 20% mince in a pan and tipping the whole thing, fat included, into a sauce keeps 150 to 250 kcal per 500g pack that a colander would have removed. That fat is not evil, but it should be counted.

Assuming the label percentage refers to cooked meat

It refers to raw. A 20% fat pack is 20% fat before anything happens to it.

Trusting turkey or chicken mince to be lighter by default

Check the fat percentage on both packs. Standard ground turkey is frequently 15% fat, which is heavier than 10% beef.

Using "1 serving" as a unit

Mince is impossible to portion by eye once it is in a sauce. Weigh the pack, count the portions, divide. It takes ten seconds and removes the biggest guess in the meal.

(For where visual estimation does and does not work, portion sizes without a scale covers the practical cues.)

Three mince dinners worth costing out

The lean bolognese (410 kcal)

• 125g raw 5% mince (171 kcal)
• 200g chopped tomatoes, onion, garlic, herbs (60 kcal)
• 150g cooked spaghetti (170 kcal)
• 1 tsp olive oil (40 kcal, measured)

Adds up to: ~440 kcal, 34g protein. The same plate with 20% mince and a free-poured pan of oil is closer to 700.

The bulked chilli (475 kcal, feeds the pan further)

• 100g raw 5% mince (137 kcal)
• 120g cooked kidney beans (140 kcal)
• Peppers, onion, tomatoes (70 kcal)
• 100g cooked rice (130 kcal)

Adds up to: ~477 kcal, 31g protein. Replacing a quarter of the mince with beans keeps the protein, adds fibre, and stretches a pack from four portions to six.

The honest burger night (480 kcal)

• 113g 95% lean patty (155 kcal)
• Brioche bun (230 kcal)
• 1 slice cheddar (60 kcal)
• Mustard, pickles, lettuce, tomato (15 kcal)
• 1 tsp oil for the pan (20 kcal)

Adds up to: ~480 kcal, 38g protein. The bun and the cheese cost more than the beef, which is the same lesson as almost every other food on this site.

For finished versions with instructions, the Korean beef bulgogi bowl and the beef and broccoli stir fry both use lean mince and steak logic.

The verdict

Two decisions decide what a mince dinner costs, and neither of them is the recipe. The first is which pack you pick up, worth about 145 kcal a portion. The second is whether the rendered fat goes into the sauce or into the sink, worth another 40 to 60.

Buy the leaner pack for saucy dishes where nobody will notice, keep the fattier one for burgers where you will, and weigh the pack rather than the plate.

Pairs well with: the chicken breast calorie breakdown, high protein dinners in 30 minutes, and how much protein you need per day.
