Formula & Mathematical Methodology: Sales Tax inclusive and exclusive formulas

Exclusive: tax = net × rate
total = net + tax. Inclusive: net = total ÷ (1 + rate)
tax = total − net.
Exclusive: tax = net × rate; total = net + tax. Inclusive: net = total ÷ (1 + rate); tax = total − net.
  • net: Price before tax
  • total: Price including tax
  • rate: The applicable rate selected by the user

Rounding: Rounded to 2 decimal places.

Worked Example: $1,000 before tax at 0%

A standard-rated United States supply is priced before Sales Tax.

  1. Tax is calculated by multiplying the net amount by 0%.
  2. The tax is added to the net amount to get the total.
Result: The total is the net price plus Sales Tax at the entered rate.
