How to Calculate Hst From Total Price Ontario

When purchasing goods or services in Ontario, the total price you pay includes the Harmonized Sales Tax (HST). Understanding how to calculate the HST from a total price can help you determine the pre-tax amount and compare prices accurately. This guide explains the HST calculation process in Ontario and provides a calculator to perform the calculation quickly.

What is HST in Ontario?

The Harmonized Sales Tax (HST) is a combined sales tax and goods and services tax that applies to most goods and services sold in Ontario. The current HST rate in Ontario is 13%. This means that when you purchase an item, 13% of the price is tax, and the remaining 87% is the actual cost of the product or service.

The HST is applied to the total price of an item, including any discounts or promotions. It is not applied to the price before discounts. This means that if you receive a discount, the HST is calculated on the discounted price.

Note: The HST rate in Ontario is subject to change. Always verify the current rate before making calculations.

How to Calculate HST from Total Price

To calculate the HST from a total price in Ontario, you can use the following formula:

HST Amount = Total Price × (HST Rate / (1 + HST Rate))

Where:

Total Price is the price you see on the receipt or invoice, including tax.
HST Rate is the current HST rate in Ontario, which is 13% or 0.13.

This formula accounts for the fact that the HST is applied to the pre-tax price, not the total price. By dividing the HST rate by (1 + HST rate), you can isolate the tax portion from the total price.

Step-by-Step Calculation

Identify the total price of the item, including HST.
Determine the current HST rate in Ontario (13% or 0.13).
Apply the formula: HST Amount = Total Price × (HST Rate / (1 + HST Rate))
Calculate the pre-tax price by subtracting the HST amount from the total price.

Using the calculator on this page, you can perform these calculations quickly and accurately.

Worked Example

Let's say you have a total price of $100, including HST. Here's how to calculate the HST amount and the pre-tax price:

HST Amount = $100 × (0.13 / (1 + 0.13)) = $100 × 0.1176 ≈ $11.76

Pre-Tax Price = $100 - $11.76 = $88.24

So, the HST amount is $11.76, and the pre-tax price is $88.24.

Description	Amount
Total Price (including HST)	$100.00
HST Amount (13%)	$11.76
Pre-Tax Price	$88.24
