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 added to the final cost paid by the consumer.

2. How Does the Calculator Work?

The calculator uses the sales tax formula:

Where:

• \( Tax \) — Sales tax amount in currency
• \( Price \) — Pre-tax price of the item
• \( Tax Rate \) — Sales tax rate as a percentage divided by 100

Explanation: The formula calculates the tax amount by multiplying the pre-tax price by the tax rate (converted from percentage to decimal). This amount is then added to the subtotal to get the final 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 their total costs, and for proper financial planning and budgeting.

4. Using the Calculator

Tips: Enter the pre-tax price in dollars and the tax rate as a percentage. Both values must be positive numbers. The calculator will display both the tax amount and the total amount including tax.
