Frequently Asked Questions About Sales Tax Calculator
How do I remove tax from a total price?
Switch to Remove mode and enter the tax-inclusive (gross) price. The calculator divides by (1 + rate/100) to find the net price, then shows the tax portion. For example, removing 10% from 110 gives a net of 100 and 10 in tax.
What is the difference between sales tax and VAT?
Both are consumption taxes added to a price. Sales tax is usually added at checkout in the US, while VAT is often already included in the displayed price in many countries. The math is the same — this tool handles either with Add or Remove mode.
Can I use any tax rate?
Yes. Enter any rate, such as 5%, 8.25%, or 20%, and the calculator applies it instantly in any currency.
