Beer Calories Formula
The Beer calories calculator uses the same formula as the ABV calculator to calculate a beers calories.
- Calories From Alcohol
1881.22 * Final_Gravity * (Original_Gravity – Final_Gravity)/(1.775 – Original_Gravity) - Calories From Carbohydrates
3550 * Final_Gravity * ((0.1808 * Original_Gravity) + (0.8192 * Final_Gravity) – 1.0004) - Total Calories
Calories From Alcohol + Calories From Carbohydrates
Approximating Beer Calories w/ ABV
If you don’t know the beers original & final gravity, we can approximate the beers calories simply by multiplying the beers ABV % by a factor of ~2.5 and then multiplying that number by how many ounces the bottle holds.
Approx. Calories = (ABV% * 2.5 ) * oz
While the above calculation won’t ever be as exact as our OG/FG formula, it’s simplicity makes it much easier to remember and apply when you’re out enjoying a few cold ones.
Let’s go through an example beer really quick just to demonstrate what kind of difference you can expect in the results between these 2 equations.
Example Beer:
-Original Gravity = 1.070
-Final Gravity = 1.018
-ABV % = 7.22
Entering the above values into our 2 formula’s above, we get a value of 228 & 216 calories respectively. In this particular example, the margin for error is about 5%.
While calculating a beers calories from the ABV% alone won’t always be quite as accurate as our example beer, the formula does tend to be much more practical out in the real world.
Below is a quick reference chart that gives you a beers estimated calories based on it’s ABV%.
Here’s the full Beer Alcohol Content List with over +250 beers to find the correct ABV you need for the above calculations.
Some Frequently Asked Questions about Beer Calories
What is a beer made up of?
Beers have four primary ingredients, namely grain, hops, yeast, and water. During the fermentation process, the sugars turn into alcohol.
Brewers use hops to eliminate the bacteria while increasing the bitterness and flavor of the wort. Around 95 percent of a beer is actually water.
