Frequently Asked Questions

How do I calculate a discount in my head?
To find 20% off: find 10% (move the decimal one spot left), double it, and subtract that from original price.
What does 50% + 20% off actually mean?
It means 50% is taken off the original price first, and then 20% is taken off the remaining balance. A $100 item becomes $50, then 20% off $50 leaves $40 (a total 60% savings, not 70%).
Can I calculate sales tax on the discounted price?
Yes, you can pair this tool with our GST/Sales Tax calculator to determine final post-tax invoice totals.
