How Sales Tax Works

Sales tax is a percentage of the purchase price that consumers pay to their local government. In many places, the sales tax rate is a fixed percentage, such as 15%, which is applied to the price of goods and services.

When you make a purchase, the sales tax is calculated as a percentage of the original price. For example, if an item costs $100 and the sales tax rate is 15%, the tax amount would be $15, and the total price would be $115.

Sales Tax Formula

Sales Tax = Original Price × (Sales Tax Rate ÷ 100)

Total Price = Original Price + Sales Tax

Understanding how sales tax works helps you budget for purchases and compare prices accurately. It's important to note that sales tax rates can vary by location, so always check the current rate for your area.

Worked Examples

Let's look at a couple of examples to see how the 15 sales tax calculator works in practice.

Example 1: Calculating 15% Sales Tax on a $50 Item

If you're buying an item that costs $50 and the sales tax rate is 15%, here's how the calculation works:

Original Price = $50
Sales Tax Rate = 15%
Sales Tax = $50 × (15 ÷ 100) = $7.50
Total Price = $50 + $7.50 = $57.50

So, for a $50 item with a 15% sales tax, you would pay $7.50 in tax and a total of $57.50.

Example 2: Calculating 15% Sales Tax on a $200 Item

If you're buying an item that costs $200 and the sales tax rate is 15%, here's how the calculation works:

Original Price = $200
Sales Tax Rate = 15%
Sales Tax = $200 × (15 ÷ 100) = $30
Total Price = $200 + $30 = $230

So, for a $200 item with a 15% sales tax, you would pay $30 in tax and a total of $230.

Note

These examples use a fixed 15% sales tax rate. In reality, sales tax rates can vary by location, so always check the current rate for your area.
