Enter the total change in BAC and the total time (hrs) into the Alcohol Burn Off Rate Calculator. The calculator will evaluate the Alcohol Burn Off Rate.

## Alcohol Burn Off Rate Formula

The following two example problems outline the steps and information needed to calculate the Alcohol Burn Off Rate.

ABOR = BAC / T

• Where ABOR is the Alcohol Burn Off Rate (bac/hour)
• CBAC is the total change in BAC
• T is the total time (hrs)

## How to Calculate Alcohol Burn Off Rate?

The following example problems outline how to calculate Alcohol Burn Off Rate.

Example Problem #1:

1. First, determine the total change in BAC.
• The total change in BAC is given as: .020.
2. Next, determine the total time (hrs).
• The total time (hrs) is provided as: 2.
3. Finally, calculate the Alcohol Burn Off Rate using the equation above:

ABOR = BAC / T

The values provided above are inserted into the equation below and computed.

ABOR = .020 / 2 = .010 (bac/hour)

Example Problem #2:

For this problem, the variables required are provided below:

total change in BAC = .030

total time (hrs) = 3
