Whether you are shopping online or managing a business, this tool makes calculations simple and accurate. In fact, it saves time and reduces manual errors.
📊 What Is Sales Tax?
Sales tax is a consumption tax applied to goods and services at the time of purchase. In other words, it is an extra percentage added to the listed price. Generally, businesses collect this tax on behalf of the government. However, the tax rate is not the same everywhere. Instead, it varies by state, region, or country. Therefore, it is important to know your local rate before making a purchase.
For example, if your purchase amount is $100 and the sales tax rate is 8%, then your total sales tax would be $8, making the final cost $108.
Calculating sales tax is simple if you follow the correct formula. First, determine the original price of the product. Next, identify the applicable tax rate in your area. Then, multiply the price by the tax rate to find the tax amount. Finally, add the tax amount to the original price to get the total cost.
For example, if a product costs $100 and the tax rate is 8%, the tax amount will be $8. As a result, the final price becomes $108. Similarly, if the product costs $250 with a 6% tax rate, the total price will increase accordingly.
Sales tax varies depending on where you live and what you’re purchasing. It is essential to know the correct rate to accurately estimate your total cost.

Sales Tax Formula:
Tax Amount = Price × Tax Rate
Total Price = Price + Tax Amount

Example 1:
Product price = $100
Tax rate = 8%
Tax = $8
Total = $108
Example 2:
Product price = $250
Tax rate = 6.5%
Tax = $16.25
Total = $266.25
