How to estimate drink calories
Use the actual pour size and the ABV on the label.
1
Enter the volume
Measure the glass or can rather than guessing the pour.
2
Add the ABV
Use the percentage printed on the label or menu.
3
Add mixers separately
The result covers alcohol only, so account for juice, syrup or cream.
What does this tool do?
Pure alcohol supplies about 7 kcal per gram, and the grams in a drink follow from volume and ABV. This calculator reports the alcohol calories per drink and for the number of servings entered.
The Formula
Ethanol (g) = volume (ml) × ABV% × 0.789; calories = ethanol grams × 7Frequently Asked Questions
How many calories are in a gram of alcohol?
About seven kilocalories per gram, compared with four for protein or carbohydrate and nine for fat.
Do mixers matter?
Yes, often more than the spirit. Juice, syrup and cream can add more calories than the alcohol itself.
