Enter the number of tasks, standard time per task, number of additional maintenance tasks, and standard time per maintenance task into the calculator to determine the Book Time.

## Book Time Formula

The following formula is used to calculate the Book Time.

BT = (N * T) + (M * S)

Variables:

- BT is the Book Time (hours)
- N is the number of tasks
- T is the standard time per task set by the manufacturer (hours)
- M is the number of additional maintenance tasks
- S is the standard time per maintenance task set by the manufacturer (hours)

To calculate the Book Time, multiply the number of tasks by the standard time per task set by the manufacturer. Then, multiply the number of additional maintenance tasks by the standard time per maintenance task set by the manufacturer. Add the two results together to get the total Book Time.

## What is a Book Time?

Book Time refers to the estimated amount of time that a particular repair or maintenance task should take in an automotive repair setting. This standard is set by the vehicle manufacturers and is used by auto repair shops to determine labor costs and scheduling. It helps to ensure consistency and fairness in pricing and allows customers to have an idea of how long a repair might take.

## How to Calculate Book Time?

The following steps outline how to calculate the Book Time using the given formula:

- First, determine the number of tasks (N).
- Next, determine the standard time per task set by the manufacturer (T) in hours.
- Next, determine the number of additional maintenance tasks (M).
- Finally, determine the standard time per maintenance task set by the manufacturer (S) in hours.
- After gathering all the variables, use the formula BT = (N * T) + (M * S) to calculate the Book Time.

**Example Problem:**

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

Number of tasks (N) = 5

Standard time per task (T) = 2 hours

Number of additional maintenance tasks (M) = 3

Standard time per maintenance task (S) = 1.5 hours
