What Is Sales Tax

Sales tax is a consumption tax applied to goods and services at the time of purchase. It is usually calculated as a percentage of the selling price.

The final consumer pays the tax, while businesses collect it and remit it to the government.

For example:

If a product costs 1,000 and the sales tax rate is 10 percent, the tax is 100, making the final price 1,100.

Sales Tax Formula Explained

There are two main calculations involved.

1. Adding Sales Tax

Sales Tax = Price × (Tax Rate / 100)
Final Price = Price + Sales Tax

2. Removing Sales Tax

Sales Tax = Total Price × (Tax Rate / (100 + Tax Rate))
Original Price = Total Price – Sales Tax

These formulas help calculate tax in both directions.

How to Use the Sales Tax Calculator

Using the calculator is simple.

Step 1: Enter the original price or total price
Step 2: Enter the tax rate
Step 3: Choose whether to add or remove tax
Step 4: Click calculate

The calculator will instantly display:

Tax amount

Price excluding tax

Example of Sales Tax Calculation

Let’s understand with a practical example.

Original Price = 2,000
Tax Rate = 8 percent

Sales Tax = 2,000 × 8 / 100 = 160

Final Price = 2,160

Now removing tax:

Total Price = 2,160
Tax Rate = 8 percent

Tax Amount = 2,160 × 8 / 108 = 160

Original Price = 2,000
