Enter the volume and alcohol content into the calculator to determine the calories in a beer. This calculator can also evaluate any of the variables given the others are known.

Beer Calories Formula

The following formula is used to calculate the calories in a beer.

C = V * D * 7.5

Variables:

  • C is the total calories in the beer (calories)
  • V is the volume of the beer (ounces)
  • D is the alcohol content by volume (decimal) 7.5 is the constant that represents the average number of calories in one gram of alcohol

To calculate the calories in a beer, multiply the volume of the beer by the alcohol content by volume, then multiply the result by 7.5.

What are Beer Calories?

Beer calories refer to the amount of energy contained in a serving of beer. The calorie content in beer can vary greatly, depending on factors such as the type of beer, the brewing process, and the alcohol content. Generally, the higher the alcohol content, the higher the calories. Consuming beer contributes to your daily calorie intake, and excessive consumption can lead to weight gain and other health issues. It’s important to note that beer also contains carbohydrates and, in some cases, small amounts of protein and fat.

How to Calculate Beer Calories?

The following steps outline how to calculate the Beer Calories using the given formula:


  1. First, determine the volume of the beer (V) in ounces.
  2. Next, determine the alcohol content by volume (D) as a decimal.
  3. Multiply the volume (V) by the alcohol content (D).
  4. Multiply the result by the constant 7.5.
  5. Finally, calculate the total calories in the beer (C).

Example Problem:

Use the following variables as an example problem to test your knowledge:

Volume of the beer (V) = 12 ounces

Alcohol content by volume (D) = 0.05

Constant (7.5) representing the average number of calories in one gram of alcohol.
