Reverse HST Calculator
Uncover the pre-tax price! Our Reverse HST Calculator quickly finds the original cost from any HST-inclusive amount in Canada. Simplify tax calculations easily.
functions Mathematical Formula
P_{before} = \frac{P_{total}}{1 + \frac{HST_{rate}}{100}}
Where:
- P_{before} = Price before HST
- P_{total} = Total price including HST
- HST_{rate} = Harmonized Sales Tax rate (as a percentage)
Understanding HST (Harmonized Sales Tax)
HST is a consumption tax in Canada, combining the federal Goods and Services Tax (GST) and a provincial sales tax (PST) into a single, harmonized tax. It's applied to most goods and services at the point of sale in participating provinces. Rates vary by province, commonly 13% or 15%.
How the Reverse HST Calculator Works
Our Reverse HST Calculator simplifies finding the original price of an item or service before HST was applied. You simply input the total price you paid (including HST) and the applicable HST rate. The tool then uses the formula: P_{before} = P_{total} / (1 + HST_{rate}/100) to quickly determine the pre-tax amount and the exact HST portion.

Frequently Asked Questions
What is the Reverse HST Calculator used for? +
This calculator helps you determine the original price of a product or service *before* the Harmonized Sales Tax (HST) was added. It's useful when you only know the final price that includes HST and want to find the pre-tax amount or the exact HST portion.
How is HST calculated in reverse? +
The reverse calculation involves dividing the total price (including HST) by (1 + HST rate as a decimal). For example, if the HST rate is 13% (0.13 as a decimal), you divide the total price by 1.13.
What are the current HST rates in Canada? +
HST rates vary by province:
- Ontario: 13%
- New Brunswick, Newfoundland and Labrador, Nova Scotia, Prince Edward Island: 15%
- Other provinces (e.g., British Columbia, Alberta, Saskatchewan, Manitoba, Quebec) have GST and/or PST, not HST.
Always verify the current rate for your specific location and type of good/service.
Can this calculator be used for GST and PST? +
This calculator is specifically designed for HST. If you're dealing with GST only, you can enter the GST rate as the 'HST Rate'. For provinces with separate GST and PST, you would typically calculate them sequentially (e.g., PST on the price including GST), which requires a different calculation method than what this tool provides for harmonized tax.
