1. What is Sales Tax?

Sales tax is a consumption tax imposed by the government on the sale of goods and services. The tax is typically calculated as a percentage of the purchase price and collected by the seller at the point of sale.

2. How Does the Calculator Work?

The calculator uses the simple sales tax formula:

Where:

• \( Amount \) — The pre-tax price of goods or services (USD)
• \( Sales\ Rate \) — The sales tax rate (expressed as decimal)

Explanation: The formula multiplies the purchase amount by the tax rate to determine the tax amount. The total is simply the sum of the original amount and the calculated tax.

3. Importance of Sales Tax Calculation

Details: Accurate sales tax calculation is essential for businesses to properly collect taxes, for consumers to understand their total costs, and for accurate financial reporting.

Tips: Enter the pre-tax amount in USD and the sales tax rate as a decimal (e.g., 0.08 for 8%). Both values must be positive numbers.
