## Reverse Tip Formula

The following formula is used to calculate the Reverse Tip.

IB = FB / (1+T/100)

- Where IB is the original bill amount before tip ($)
- FB is the final bill amount ($)
- T is the tip percentage (%)

To calculate a reverse tip, take the final bill amount and divide it by the result of 1 plus the tip percentage over 100.

## How to Calculate Reverse Tip?

The following example problems outline how to calculate Reverse Tip.

Example Problem #1:

- First, determine the final bill amount ($).
- The final bill amount ($) is given as: 100.

- Next, determine the tip percentage (%).
- The tip percentage (%) is provided as: 15.

- Finally, calculate the Reverse Tip using the equation above:

IB = FB / (1+T/100)

The values given above are inserted into the equation below and the solution is calculated:

IB = 100 / (1+15/100) = 86.956 ($)

Example Problem #2:** **

For this problem, the variables required are provided below:

final bill amount ($) = 200

tip percentage (%) = 20

Test your knowledge using the equation and check your answer with the calculator above.

IB = FB / (1+T/100)** = ?**
