1. What is Sales Tax?

Sales tax is a consumption tax imposed by the government on the sale of goods and services. It is 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 sales tax formula:

Where:

• \( \text{Price} \) — Original price before tax (dollars)
• \( \text{Tax Rate} \) — Sales tax rate as a decimal fraction
• \( \text{Sales Tax} \) — Amount of tax to be paid (dollars)

Explanation: The formula multiplies the original price by the tax rate to determine the tax amount. The total price is then calculated by adding the sales tax to the original price.

3. Importance of Sales Tax Calculation

Details: Accurate sales tax calculation is essential for businesses to comply with tax regulations, for consumers to understand the true cost of purchases, and for proper financial planning and budgeting.

4. Using the Calculator

Tips: Enter the price in dollars and the tax rate as a decimal fraction (e.g., 0.08 for 8%). Both values must be valid (price > 0, tax rate between 0-1).

5. Frequently Asked Questions (FAQ)
