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:

• \( ST \) — Sales tax amount in dollars
• \( Subtotal \) — Purchase amount before tax in dollars
• \( Rate \) — Sales tax rate as a percentage

Explanation: The sales tax amount is calculated by multiplying the subtotal by the tax rate (converted from percentage to decimal).

3. Importance of Sales Tax Calculation

Details: Accurate sales tax calculation is essential for businesses to comply with tax regulations, maintain proper financial records, and provide customers with correct pricing information.

4. Using the Calculator

Tips: Enter the subtotal amount in dollars and the sales tax rate as a percentage. Both values must be positive numbers (subtotal > 0, rate ≥ 0).
