How to Use the Reverse Tip Calculator

  1. Enter the total amount you paid (including tip) in the "Total Amount" field.
  2. Enter the tip percentage you were charged in the "Tip Percentage" field.
  3. Click the "Calculate" button to determine the original bill amount before the tip.
  4. The calculator will display the original bill amount, the tip amount, and the tip percentage of the original bill.

Example

If you paid a total of $55 with a 15% tip:

  • Total Amount: $55.00
  • Tip Percentage: 15%
  • Original Bill: $47.83
  • Tip Amount: $7.17
  • Tip Percentage of Original Bill: 15.0%

Working Principle

The calculator uses the formula: Original Bill = Total Amount / (1 + Tip Percentage / 100). This formula works because if you add a tip percentage to the original bill, you're essentially multiplying the original bill by (1 + tip percentage / 100). To reverse this calculation, you divide the total amount by this same factor.
