  • This percentage, called the Sales Tax Rate, varies from state to state, in Texas for example there is a general sales tax rate of around 6.25%.

Example of reverse calculating the Sales Tax and the List Selling Price out of the Final Price with the tax

  • Let's say that a person who lives in an area where the sales tax rate is 5% bought some cider and had to pay a total of a $525 dollar bill that included the sales tax.
  • "Price without sales tax"
    • = "Sales tax charged price" ÷ (1 + "Sales tax rate%")
    • = $525 ÷ (1 + 5%)
    • = $525 ÷ (1 + 5/100)
    • = $525 ÷ (1 + 0.05)
    • = $525 ÷ 1.05
    • = $500 dollars.
  • That person had to pay a "Sales tax amount"
    • = "Sales tax charged price" - "Price without sales tax"
