Frequently asked questions
What is the difference between sales tax and VAT?
Sales tax is typically added at the point of sale and is not included in the displayed price, while VAT (value-added tax) is often included in the displayed price. This calculator handles sales tax, but the VAT calculator on UTIQO follows a similar logic.
Can I use this calculator for any currency?
Yes, the calculator uses a dollar sign prefix by default, but the mathematical logic works for any currency. Simply enter the amount in your desired currency.
Why does the extracted tax amount differ from simply multiplying the total by the rate?
Because the tax is calculated on the pre-tax price, not on the total. To extract correctly, you must divide the total by (1 + rate/100) to find the pre-tax price first.
