This simple calculator will tell you the percentage of alcohol by volume (ABV) of your home brew according to the original and final gravity readings.

This ABV calculator derives the alcohol content of your beer/wine using a simple formula. If you want to find out more about the maths or using a hydrometer to get your original and final gravity figures of your home brew then read through the hydrometer article here.

This ABV calculator uses a simple formula to also calculate an estimate of the calories in your home brew. This is worked out by calculating the number of calories that are in the alcohol in the beer/wine as well as adding the number of carbohydrates that we can roughly work out from the finishing gravity.
