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.
