Frequently asked questions
How do I calculate sales tax?
Multiply the price by the tax rate divided by 100 to get the tax, then add it to the price for the total.
How do I find the price before tax?
Divide the tax-inclusive total by (1 + rate). For 8.5% tax, divide by 1.085.
What is the difference between sales tax, VAT and GST?
Sales tax is added at checkout (US style); VAT and GST are often included in the displayed price and have their own calculators.
Which rate should I use?
The rate that applies where the sale happens — sales tax varies by state, county and city.
