How many calories are in whole milk?
USDA numbers for whole (3.25% fat) milk per 100 g, per cup, per fluid ounce and per tablespoon, with macros.
Whole milk (3.25% fat) is 61 calories per 100 g, which sounds trivial until you pour a cup: 244 g and about 149 calories. The calories people miss are the small ones, a splash in coffee several times a day, or the milk in cereal that never gets logged. Compared with skim milk the difference is entirely fat; protein and sugar are nearly identical.

Calories per serving
Per-100 g numbers are only useful once you know your portion. Typical servings of whole milk:
| Serving | Calories | kJ | Protein | Carbs | Fat |
|---|---|---|---|---|---|
| 1 cup (244 g) | 149 | 623 | 7.7 g | 12 g | 7.9 g |
| 1 fl oz (30 g) | 19 | 78 | 1 g | 1.5 g | 1 g |
| 1 tbsp (15 g) | 9 | 38 | 0.5 g | 0.7 g | 0.5 g |
Macro breakdown
By calories whole milk is 48% fat, 31% carbohydrate and 21% protein. A cup carries 7.7 g of protein, about 12 g of naturally occurring sugar (lactose) and 4.6 g of saturated fat, which is the main nutritional difference between whole and lower-fat milk.

Is whole milk good for weight loss?
Whole milk is not a problem food, but it is an easy place to find 50 to 70 calories a day. A cup is about 149 calories; the same cup of 2% milk is about 122 and skim is about 83, so switching saves 27 or 66 calories per cup with no change in protein. If you drink one glass a day, that is a small lever; if milk goes into three coffees, cereal and a smoothie, it adds up. The protein in a cup (7.7 g) does help with fullness, which a sweetened drink will not give you. Decide based on how much you actually use: measure a week's worth and see.
How to log whole milk in Cal.AI
For a glass, search for whole milk and log 1 cup (244 g, about 149 calories); for a carton, scan the barcode once and save it for one-tap reuse. In coffee, log the splash honestly: 1 fl oz (30.5 g) is about 19 calories and a tablespoon (15 g) about 9, and a latte uses far more than a splash. The common mistake is leaving milk off cereal and smoothies altogether, which can hide a cup or more, about 149 calories, every day.
Frequently asked questions
How many calories are in a cup of whole milk?
A cup of whole milk (244 g) has about 149 calories, with 7.7 g of protein, 11.7 g of carbohydrate and 7.9 g of fat, of which 4.6 g is saturated. It also supplies about 276 mg of calcium and 105 mg of sodium. A fluid ounce is about 19 calories, and a tablespoon about 9, so small pours add up quietly.
Is whole milk much higher in calories than skim milk?
Per cup, whole milk is about 149 calories and skim milk about 83, a difference of 66 calories. Per 100 g it is 61 against 34. All of the gap is fat: whole milk has 3.25 g per 100 g and skim has 0.08 g. Protein (3.15 g versus 3.37 g) and sugar (about 5 g per 100 g in both) barely move.
How many calories does milk add to coffee?
It depends on the pour. A tablespoon of whole milk (15 g) adds about 9 calories, a fluid ounce (30.5 g) about 19, and a quarter cup (61 g) about 37. A coffee with a real splash, two or three times a day, can reach 60 to 110 calories that rarely get logged. Measure your usual pour once so you know.
