1. What is Sales Tax Calculation?

Sales tax calculation determines the additional amount charged on goods and services based on a percentage rate set by local authorities. The total amount paid is the sum of the subtotal and the calculated tax.

2. How Does the Calculator Work?

The calculator uses the sales tax formula:

Where:

• \( Subtotal \) — Original price before tax
• \( Tax\ Rate \) — Percentage tax rate (e.g., 8.25 for 8.25%)
• \( Total \) — Final price including tax

Explanation: The tax rate is converted from percentage to decimal form (divided by 100) before being applied to the subtotal.

3. Importance of Tax Calculation

Details: Accurate tax calculation is essential for proper pricing, accounting, and financial planning for both businesses and consumers.

4. Using the Calculator

Tips: Enter the subtotal amount (without tax) and the tax rate percentage. Both values must be positive numbers.
