1. What is the Reverse Sales Tax Calculator?

The Reverse Sales Tax Calculator calculates the pre-tax amount when you know the total amount paid including tax. This is useful for expense tracking, accounting, and understanding the tax component of purchases.

2. How Does the Calculator Work?

The calculator uses the reverse sales tax formula:

Where:

• Total Amount — The amount paid including tax (CAD)
• Tax Rate — The applicable tax rate (e.g., 0.12 for 12%)

Explanation: The equation reverses the standard sales tax calculation to determine the original price before tax was added.

3. Importance of Pre-tax Calculation

Details: Knowing the pre-tax amount is essential for accurate financial reporting, budgeting, and understanding the true cost of goods and services before taxes.

4. Using the Calculator

Tips: Enter the total amount paid (including tax) in CAD and the tax rate as a decimal (e.g., 0.12 for 12%). The calculator will determine the original price before tax.
