• BP is the total battery price ($) • W is the warranty length (months) To calculate a battery pro rata, divide the battery price by the total warranty length. ## How to Calculate Battery Pro Rata? The following steps outline how to calculate the Battery Pro Rata. 1. First, determine the total battery price ($).
2. Next, determine the warranty length (months).
3. Next, gather the formula from above = BPR = BP / W.
4. Finally, calculate the Battery Pro Rata.
5. 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 battery price (\$) = 300

warranty length (months) = 6

BPR = BP / W = ?
