How to work out sales taxes - Step by Step

Here are the solutions to the questions stated above:

1) You purchase a item for 81 dollars and pay 6.85 % (percent) in tax. How much is tax and the final retail price including tax?

  • Firstly, if the tax is expressed in percent, divide the tax rate by 100. You can do this by simply moving the decimal point two spaces to the left. In this example, we do 6.85/100 = 0.0685
  • Now, find the tax value by multiplying tax rate by the item value:

    tax = 81 × 0.0685

    tax = 5.5485
  • Finally, add tax to the before tax price to get the final price including tax:

    The final price including tax = 81 + 5.5485 = 86.5485

Sales tax Formula (Final Price)

Final price including tax = before tax price × (1 + tax rate (%) / 100)

or, if the tax is alread expressed in decimal,

Final price including tax = before tax price × (1 + tax rate)


2) You buy a item for 86.5485 dollars after tax was added. You know that the applicable tax rate is 6.85%. How much is the before tax price?

  • Divide the percentage added to the original by 100. Here, a sales tax of 6.85 percent was added to the bill to make it 86.5485. So, divide 6.85 by 100 to get 0.0685.
  • Add one to the percentage, expressed as a decimal. In this example, add one to 0.0685 to get 1.0685.
  • Divide the final amount by the result of the previous step to find the original amount before the percentage was added. In this example, divide 86.5485 by 1.0685 to find the amount before the sales tax was added, which equals 81.

Sales tax Formula (Before Tax Price)

Before Tax Price ($) = Final price / (1 + tax rate(%) / 100)

or, if the tax is alread expressed in decimal,

Before Tax Price ($) = Final price / (1 + tax rate)

More about sale taxes

Tax rates vary widely by jurisdiction and range from less than 1% to over 10%. Tax is collected by the seller at the time of sale. A sales tax is imposed at the retail level. In cases where items are sold at retail more than once, such as used cars, the sales tax can be charged on the same item indefinitely. To determine the (total) tax rate you should identify the total amount of tax you must charge. If, for example, a state has a two percent tax rate, a given county two percent and a city one percent, the total tax rate applicable is five percent: 2 + 2 + 1 = 5.
