Worked Examples

Let's look at two practical examples to understand how the reverse HST calculator works.

Example 1: Calculating Original Price

Suppose you have a total amount of $226 and want to find the original price before 13% HST was added.

1. Enter $226 in the "Total Amount" field.
2. Select 13% from the HST rate dropdown.
3. Click "Calculate".

The calculator will show:

• Original Price: $200
• HST Amount: $26
• Total Amount: $226

This means the original price was $200, and $26 was added as HST to reach the total of $226.

Example 2: Verifying a Receipt

You receive a receipt showing a total of $77 and want to verify the original price.

1. Enter $77 in the "Total Amount" field.
2. Select 13% from the HST rate dropdown.
3. Click "Calculate".

The calculator will show:

• Original Price: $67.42
• HST Amount: $9.58
• Total Amount: $77.00

This confirms that the original price was approximately $67.42, and $9.58 was added as HST.
