Calories in regular beer.
43 kcal per 100 g.
Regular beer is 43 kcal per 100 g: about 150 kcal per 355 ml can and 215 per 500 ml pint. Roughly two-thirds of that is the alcohol itself, the rest residual carbohydrate — which is why "low-carb" beer is only modestly lower in calories.

Energy comes from USDA nutrient 1008. Salt is calculated as sodium × 2.5, with unit conversion to grams. It is not a separately measured salt value.
Preparation
Regular beer is 43 kcal per 100 ml and carries no fat and almost no protein — the energy is alcohol and residual carbohydrate. Nothing about serving temperature, pouring or head changes it. Alcohol itself is 7 kcal per gram, between carbohydrate at 4 and fat at 9, and it is the part of a drink that no label in most countries is required to declare.
Logging this food
A 12 fl oz can is 356 g and 153 kcal; a fluid ounce is 30 g and 13. A pint is around 500 ml and roughly 215 kcal. Beer is the drink most often left out of a food log entirely, and four cans over an evening is 612 kcal — a meal's worth, invisible, and repeated most weekends.
Swaps and alternatives
Light beer is 29 kcal per 100 ml against this row's 43: a can drops from 153 to 103. Across a session that is a real saving. A 5 fl oz glass of wine is 123 kcal and a jigger of spirits 97, so the comparison depends entirely on how many of each you would have.
