HST Reverse Calculation Formula

Original Price = Final Price / (1 + HST Rate)

Where:

  • Final Price is the total amount including HST
  • HST Rate is the applicable tax rate (e.g., 13% for Ontario)

This formula reverses the HST calculation to find the original price before taxes were added.

Worked Example

Let's look at an example to understand how the HST Reverse Calculator works.

Example Calculation

Suppose you have a final price of $114.50 including HST at a rate of 13%.

Using the formula:

Original Price = $114.50 / (1 + 0.13) = $114.50 / 1.13 ≈ $101.33

So, the original price before HST was approximately $101.33.

This example shows how the calculator helps you determine the pre-tax amount from the final price including HST.
