The HST Calculator is:
Our HST calculator’s calculator does two sorts of calculations:
Tax calculations forwards and backwards
| Forward Calculation | Reverse Calculation |
| This is the standard manner. You enter the base price and select your province and the calculator doubles the amount by the current HST rate. For example, if you enter $100 and pick Ontario (13% HST), the output will show the final amount as $113. | When you know the entire price and want to take off HST to find the original cost. But a reverse computation works the other way, taking the tax out of the total. This is important if you are getting pricing that include tax and need to extract the tax for accounting purposes. |
Province Selection
You pay different tax rates depending where in Canada you are. The calculator includes all provinces including Ontario, Nova Scotia, New Brunswick, Newfoundland & Labrador, Prince Edward Island, Alberta, British Columbia, Saskatchewan, Manitoba and Quebec. Each is subject to distinct tax structures (HST, GST, PST or QST).
Actual Calculations
This is not an estimation calculator. Calculations are based on current, official Canadian tax rates, adjusted to suit CRA rules. Results are accurate to the cent.
How to Use a HST Calculator: A Step-by-Step Guide?
It is quite easy to use our HST Calculator Canada. Just follow these few steps:
Step 1 – Input Your Amount
First fill in the price or amount you want to calculate. Enter the amount, which is the basic price (before tax). You can type any value starting from 0.01 dollar and above. Whether you are buying anything for $5.99 or making a $10,000 business deal the calculator works just as effectively for all sizes.
Step 2 – Choose Your Province
Choose your province from the drop down menu. This is essential because tax rates are not uniform across Canada. Each province has its own sales tax system:
Ontario – GST 13%
Nova Scotia – 15% HST
New Brunswick – 15% Harmonised Sales Tax (HST)
Newfoundland & Labrador – HST 15%
Prince Edward Island – 15% GST
Alberta – 5% GST only
British Columbia – 5% GST + 7% PST
Saskatchewan – 5% PST + 6% PST
Manitoba – GST of 5%, HST of 8%.
Quebec – GST of 5% + PST of 9.975%
Otherwise results will be wrong if you choose the wrong province . Make sure you are in the right place before you calculate.
Step 3 – Choose Calculation Type (Pre or Post Tax)
Determine if your sum is pre or post tax:
Before Tax — Choose this option if you have a base price and wish to add tax on top. Most popular for invoice calculating and shopping.
After Tax – This is used when you have the entire cost and simply want to eliminate tax to find the original pricing. Required for HST back-calculation.
This will make a major impact in your results so choose wisely what you require
Step 4 – Click on Calculate
Input the dollar amount and select your province and the type of calculation you wish to do. Then press the Calculate button. The calculator will process your input instantaneously.
Step 5: Check Your Results

Using a HST Calculator Common Mistakes to Avoid
Inaccurate Tax Amounts
Selecting the wrong province will lead to inaccurate tax amounts. Alberta has 5 % GST , Atlantic provinces 15 % HST . Know where you are always.
Confusing Calculation Direction
“Before Tax” instead of “After Tax” will turn your results upside down. Please choose the option that pertains to you.
Forget reverse tax function
If you have a total and need the original price, do reverse calculation instead than trying to guess. This makes it correct.
Old Tax Rates
Mistakes will be made when old computations are bookmarked with old tax rates. Results are based on current rates; check for updates.
Rounding Errors
Rounding manually reduces accuracy. The calculator will automatically do exact cents.
HST vs. GST/PST
Some provinces have HST, and some have GST plus PST. Provincial types cannot be mixed in calculations.
Incorrect Invoice Amounts
Check your base pricing before you calculate. Small faults get magnified across several items.
Business versus Personal Confusion
Some businesses have different tax duties. If you are not sure of the applicability, please contact CRA.
How to Calculate HST Correctly?

Save Invoices & Records

Verify GST/PST Provinces
If provinces are using GST plus PST or QST, make sure the calculator takes both into account.
Check the Calculation Type
Make sure you are adding tax or removing tax before you hit calculate.
Look at the specific results, not just the bottom line. Look for surprises in the breakdown.
Calculation of HST Forward/Reverse
Forward computation:
When to use – You have a basic price and wish to add tax
Formula – Base Price x 1 + Tax Percentage
Example – $100 x 1.13 (Ontario) equals $113 total
Back-Calculation:
When to Use – When you know a final pricing and want to take tax off
Formula = Total Price / (1 + Tax Rate)
$113 / 1.13 = $100 basic pricing
You are using the calculator appropriately in any case when you use both techniques.
HST, GST, PST & QST Explained
