Why does alcohol have so many calories?

Ethanol (pure alcohol) contains 7 kcal per gram — nearly as much as fat (9 kcal/g) and almost double carbs or protein (4 kcal/g). A standard drink with 14g of alcohol provides about 98 kcal from ethanol alone, before any carbs or mixers.

Does higher ABV always mean more calories?

Yes. All else equal, higher ABV means more pure ethanol and therefore more calories. A 9% ABV craft beer has roughly 50% more alcohol calories than a 5% ABV lager of the same volume.

Why are spirits lower in carb calories than beer?

Distillation removes virtually all sugars and carbohydrates. Spirits like vodka, whiskey, and gin have near-zero carb calories. Beer retains fermented sugars and starches, adding 20–60 kcal from carbs per serving.

How accurate is the walking burn estimate?

The estimate uses 280 kcal/hr for a 70 kg person walking at moderate pace (~4–5 km/h). Actual burn varies with body weight, pace, and fitness. Use it as a rough guide, not a precise measurement.

Summary

Enter your drink type, volume, and ABV to see exact calories from alcohol and carbs, plus how long to walk it off.

How it works

Select a preset drink type (beer, wine, spirits, cocktail) or choose Custom.
Enter the volume in mL or fl oz and the ABV percentage.
The calculator computes alcohol calories using the ethanol density formula (0.789 g/mL × 7 kcal/g).
Carbohydrate calories are estimated from typical values for each drink type.
Results show total calories and equivalent walking time based on a 70 kg person burning 280 kcal/hr.

Use cases

Track calorie intake when drinking socially while managing diet goals.
Compare calorie impact of beer vs. wine vs. spirits before choosing a drink.
Understand how ABV affects the caloric content of craft beers and cocktails.
Estimate how much exercise is needed to offset alcohol calories.
