How to Calculate Sales Tax?

Sales tax is a government-imposed charge applied to the sale of goods and services. The rate varies depending on your state or country of residence. To calculate sales tax, you need:

• The price before tax (net price) or the total price (including tax)
• The applicable sales tax rate
• Whether you want to add sales tax (find the total price) or subtract sales tax (find the original price before tax)

Formulas:

• To add sales tax: Net Price × (1 + Tax Rate) = Gross Price
• To subtract sales tax: Gross Price ÷ (1 + Tax Rate) = Net Price

Our tax calculator sales does the math instantly, eliminating manual errors.

Examples of Calculating Sales Tax

Example 1 – Adding Sales Tax (U.S. 8%):

Mia is shopping for a new backpack at a store in a U.S. state where the sales tax rate is 8%. The price tag on the backpack says $100, which is the price before tax.

Mia wants to know how much she will actually have to pay, including tax.

Calculation:

• Net Price (before tax): $100
• Sales Tax: $100 × 8% = $8
• Total Price (after tax): $100 + $8 = $108

Mia will pay $108 total for the backpack at the register.

Example 2 – Subtracting Sales Tax (U.S. 8%):

Jacob bought a pair of shoes, and the receipt shows he paid $108 total (including sales tax). He wants to figure out how much the shoes cost before tax, and how much sales tax he paid.

Calculation:

• Total Price (including tax): $108
• Net Price (before tax): $108 ÷ 1.08 = $100
• Sales Tax: $108 – $100 = $8

Jacob paid $100 for the shoes and $8 in sales tax.

FAQs

How do I calculate sales tax from a total?

To calculate sales tax from the total price, use the reverse sales tax formula:

Net Price = Total Price ÷ (1 + Tax Rate)

Sales Tax = Total − Net

Example:

Total price (with tax): $108.00, Tax rate: 8% = 0.08

Net Price = Total ÷ (1 + Tax Rate)

$108.00 ÷ 1.08 = $100.00

Sales Tax = Total − Net

$108.00 − $100.00 = $8.00

What is the formula to calculate sales tax?

• To add sales tax: Net Price × (1 + Tax Rate) = Gross Price
• To subtract sales tax: Gross Price ÷ (1 + Tax Rate) = Net Price
