1. What is the Reverse Sales Tax Calculation?

The reverse sales tax calculation determines the original price of an item before tax was added. For New Jersey seniors, this helps understand how much of a purchase went to the state (standard rate 6.625%) versus the actual item cost.

2. How Does the Calculator Work?

The calculator uses the New Jersey sales tax formula:

Where:

• \( \text{Total Amount} \) — The final price including tax (USD)
• \( \text{Tax Rate} \) — New Jersey standard sales tax rate (0.06625 for 6.625%)

Explanation: The equation works backward from the total paid to determine the original price before tax was added.

3. Importance of Pre-tax Calculation

Details: Understanding pre-tax amounts helps with budgeting, expense tracking, and verifying proper tax application on receipts. For seniors with potential exemptions, this provides a baseline comparison.

4. Using the Calculator

Tips: Enter the total amount paid (including tax) in USD. The default NJ tax rate is 6.625% (0.06625), but you may adjust if using a different rate. All values must be positive numbers.
