Formula
Add: total = price × (1 + rate/100). Remove: subtotal = total ÷ (1 + rate/100).
Example
$100 + 8.875% tax = $108.88. From $108.88 tax-included → $100.00 subtotal.
Frequently asked
Does it support VAT or GST?
Yes — enter any rate. The math is identical for VAT, GST, sales tax and similar consumption taxes.
Why isn't a default rate filled in?
Sales tax varies by city, state and country. We never assume — you set the rate.
Can I add multiple taxes?
Add the rates together (e.g. 6% state + 2% city = 8%). For tiered taxes, calculate each layer separately.
