How to Calculate Sales Tax
To calculate sales tax manually, multiply the item’s price by the sales tax rate. If your tax rate is listed as a percentage, divide it by 100 to convert it into a decimal before using it in calculations.
Steps to calculate sales tax:
- Find the price before tax and sales tax percentage.
- Divide the tax percentage by 100 to convert it into a decimal.
- Multiply the price before tax by the decimal rate to get the sales tax amount.
- Add the sales tax to the original price to get the total price after tax.
Example:
If you buy a coffee maker priced at $70 and your state’s sales tax rate is 6.5%, the calculation is:
- Convert tax rate: 6.5 ÷ 100 = 0.065
- Find sales tax: 70 × 0.065 = 4.55
- Find total price: 70 + 4.55 = $74.55
So, the sales tax is $4.55, and the total cost is $74.55.

Sales Tax Calculation Formulas
Here are plain text formulas for different ways to find sales tax values:
- Sales tax amount = Original price × Sales tax rate (decimal)
- Sales tax rate (decimal) = Sales tax percent ÷ 100
- Total price after tax = Price before tax + Sales tax amount
- Or, Total price after tax = Price before tax × (1 + Sales tax rate)
- Original price before tax = Total price after tax ÷ (1 + Sales tax rate)
- Sales tax amount = Total price after tax – Price before tax
- Sales tax percent = (Sales tax amount ÷ Price before tax) × 100
These formulas make it simple to calculate any of the missing values, whether you need to find the tax amount, total cost, or original price.

What is Sales Tax?
Sales tax is a government-imposed tax applied to the sale of goods and services. It funds essential public programs such as education, healthcare, and infrastructure.
In the United States, all states except Alaska, Delaware, Montana, New Hampshire, and Oregon charge a state-level sales tax. However, even in Alaska, some local areas apply their own local sales taxes.
Certain items may be exempt from sales tax depending on state laws. For example:
- In Massachusetts, most grocery items are tax-free, but ready-to-eat foods like sandwiches are taxable.
- Some states apply higher “tourist taxes” to hotels, restaurants, or car rentals in popular destinations.
Always check your state and local tax rates, as some areas add surcharges on top of the base state rate.
Sales Tax on Cars and Large Purchases
When buying vehicles or expensive equipment, expect to pay sales tax on the purchase price. Even if you finance your car through a loan, the tax is included in the total loan amount.
Certain non-profit organizations may be exempt from paying sales tax, but individuals generally are not. If you’re unsure about your obligations, consult a certified tax professional or check your local tax department’s website.
