The calculation for Ontario HST is straightforward. The formula used is:

Where:

• Pre-tax Amount is the price before tax
• HST Rate is the current tax rate in Ontario (13% as of 2023)

This formula is applied to all taxable goods and services sold in Ontario. The HST rate is set by the Ontario government and may change periodically.

Worked Examples

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

Example 1: Calculating HST on a $100 Purchase

If you buy an item priced at $100 before tax with a 13% HST rate:

• HST Amount = $100 × (13 / 100) = $13
• Total Amount = $100 + $13 = $113

Using our calculator, you would enter $100 as the pre-tax amount and select 13% as the HST rate to get these results.

Example 2: Calculating HST on a $50 Purchase

For a $50 item with the same 13% HST rate:

• HST Amount = $50 × (13 / 100) = $6.50
• Total Amount = $50 + $6.50 = $56.50

This shows how the HST amount scales with the price of the item. The calculator makes it easy to see these relationships quickly.
