Frequently Asked Questions
How do you calculate sales tax?
To add sales tax, multiply the net price by the tax rate percentage. For example, a $100 item with 10% tax costs $110 total.
How do I extract sales tax from a total?
Divide the gross total by (1 + tax rate). If the total is $110 and tax is 10%, divide 110 by 1.10 to get the $100 net price.
Are sales tax rates the same everywhere?
No, sales tax varies wildly by country, state, and even local municipality.
