Enter the total volume in the fermenter (gallons) and the average losses (gallons) into the Pre-Boil Volume Calculator. The calculator will evaluate the Pre-Boil Volume.

## Pre-Boil Volume Formula

The following two example problems outline the steps and information needed to calculate the Pre-Boil Volume.

**PBV = VF + AL**

Variables:

- PBV is the Pre-Boil Volume (gallons)
- VF is the total volume in the fermenter (gallons)
- AL is the average losses (gallons)

## How to Calculate Pre-Boil Volume?

The following steps outline how to calculate the Pre-Boil Volume.

- First, determine the total volume in the fermenter (gallons).
- Next, determine the average losses (gallons).
- Next, gather the formula from above = PBV = VF + AL.
- Finally, calculate the Pre-Boil Volume.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

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

total volume in the fermenter (gallons) = 3

average losses (gallons) = 1.75

PBV = VF + AL** **= ?
