Frequently asked questions

How is sales tax calculated?
Multiply the price by the sales tax rate to get the tax amount, then add it to the price for the total.
Does this use a fixed tax rate?
No. You enter the rate that applies to your location, so it is not tied to any specific state or country.
How is this different from VAT?
The maths is similar. Sales tax is added at the final sale, while VAT is collected at each stage. Use the VAT Calculator if you also need to remove VAT.
