Calculate the total cost of goods including Ontario's Harmonized Sales Tax (HST) and Provincial Sales Tax (PST). This calculator helps you determine the final price after sales tax is applied in Ontario.
How the Calculator Works
Ontario uses a Harmonized Sales Tax (HST) system, which combines the federal Goods and Services Tax (GST) and the provincial sales tax into a single rate. The current HST rate in Ontario is 13%.
To calculate the total cost including sales tax:
- Enter the original price of the item
- Select whether you want to calculate the total price including tax or just the tax amount
- Click "Calculate" to see the result
Note: Some items may be exempt from sales tax in Ontario. Check with the Ontario Ministry of Finance for specific exemptions.
Formula Used
The calculation is straightforward:
Total Price = Original Price × (1 + Tax Rate)
Tax Amount = Original Price × Tax Rate
Where the Tax Rate is 13% (0.13) for Ontario HST.
For example, if an item costs $100 before tax:
- Total price including tax: $100 × 1.13 = $113
- Tax amount only: $100 × 0.13 = $13
Worked Examples
Example 1: Calculating Total Price
If you have an item priced at $75 before tax:
- Original price: $75
- Tax rate: 13%
- Total price = $75 × 1.13 = $84.75
The total cost including tax is $84.75.
Example 2: Calculating Tax Amount
For an item priced at $120 before tax:
- Original price: $120
- Tax rate: 13%
- Tax amount = $120 × 0.13 = $15.60
The tax amount is $15.60.
