1. What is the Reverse Sales Tax Calculator?

The Reverse Sales Tax Calculator calculates the original price before California state sales tax (7.25%) was added. This is useful for expense tracking, accounting, and understanding the true cost of items before tax.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Total Amount — The final price including tax (USD)
• Tax Rate — California state sales tax rate (0.0725 for 7.25%)

Explanation: The formula works backward from the total amount to determine how much of that total was the original price and how much was tax.

3. Importance of Calculating Pre-tax Amount

Details: Knowing the pre-tax amount is important for budgeting, expense reports, accounting records, and understanding the true cost of goods and services before taxes.

4. Using the Calculator

Tips: Enter the total amount paid (including tax) in USD and the tax rate as a decimal (0.0725 for California's 7.25% rate). The calculator will show both the pre-tax amount and the tax amount.
