About this tool

The Sales Tax Calculator adds provincial, state, or combined tax rates to any purchase amount, giving you the final out-of-pocket cost before you commit to a buy. It is useful for shoppers, small business owners, and freelancers who need to quote tax-inclusive prices or reconcile receipts without doing mental math.

Reach for this tool when you are comparing prices across jurisdictions, building a budget that needs to account for tax, or confirming that a vendor charged you the correct amount. It handles both flat-rate and tiered tax structures, so it works whether you are buying in Ontario, Alberta, or a US state.

How to use it

1. Enter the pre-tax purchase amount in the price field.
2. Select your jurisdiction from the dropdown or enter a custom rate manually.
3. Choose whether the listed price is tax-exclusive or tax-inclusive.
4. Click Calculate to see the tax amount and total cost broken down.
5. Copy or note the result for your invoice, budget, or price comparison.

Pro tips

• If comparing cross-border prices, run both jurisdictions separately and compare totals rather than relying on base price alone.
• Use the tax-inclusive mode when working backward from a receipt to verify the pre-tax amount a vendor charged.
