Find Sales Tax Amount & Total Price With Sales Tax
Y% sales tax added to $X = $Z
Sales Tax Formula: Y% * $X / 100 = $Z
where
- X = purchase price
- Y = sales tax percent
- Z = sales tax amount
Total Price Formula: $X * (1 + (Y%/100) = $Z
where
- X = purchase price
- Y = sales tax percent
- Z = price after sales tax
Reverse Sales Tax Calculator: Find Price of Tax-exempt Purchases
$X - Y% VAT = $Z
Reverse Sales Tax Pricing Formula: $X * ((100 - Y%) / 100) = $Z
where
- X = final price
- Y = sales tax percent
- Z = price before sales tax
Reverse Sales Tax Formula: $X * (1 - (1 - Y%/100)) = $Z
where
- X = final price
- Y = sales tax as a decimal
