Beer Calories Calculator

It works two ways. If you know the original and final gravity from a brew, it uses the standard home-brewing formula (6.9 times alcohol by weight plus 4.0 times the residual extract, scaled per 12 fluid ounces), which accounts for both alcohol and leftover sugar. If you only have the label, it adds the alcohol calories (about 19.4 calories per percent of ABV in 12 fluid ounces) to the carb calories (3.8 calories per gram), using your style preset or your own ABV and carb figures.

It depends on the strength and the carbs. A light lager near 4.2% ABV lands around 100 to 110 calories, a standard 5% lager around 140 to 155, a 6.5% IPA around 190 to 210, and a 9% to 10% imperial stout or barley wine can pass 300 calories. Enter your beer's details to get a figure tuned to that specific brew.

Calories scale directly with volume. The calculator quotes a per 12 fluid ounce figure, then multiplies by your serving in ounces divided by 12. A 16 ounce US pint holds about one third more beer than a 12 ounce can, so it carries about one third more calories, and a 20 ounce imperial pint carries about two thirds more.

In most beers, alcohol is the larger share. Ethanol provides about 7 calories per gram, while residual carbohydrate provides about 3.8 calories per gram. The calculator splits the two so you can see each part. Light beers shift the balance toward alcohol because brewers ferment out most of the sugar, while sweet stouts and barley wines carry more carb calories.

Yes. Set the number of drinks and the calculator totals the calories across all of them, then converts the alcohol to US standard drinks. One US standard drink is 14 grams of pure ethanol, which is roughly one 12 ounce beer at 5% ABV. A 16 ounce pint at the same strength counts as about 1.3 standard drinks.

Treat them as close estimates, not exact label values. Real calories shift with the recipe, adjuncts, priming sugars, and finishing gravity, and published label figures are themselves rounded. Use the gravity mode when you have real readings for the best accuracy, and the style or ABV mode for a quick estimate from the can.
