1. What Is The Tax Rate Formula?

The tax rate formula calculates the percentage of income that is paid in taxes. It provides a standardized way to compare tax burdens across different income levels and jurisdictions.

2. How Does The Calculator Work?

The calculator uses the tax rate formula:

Where:

• \( TR \) — Tax Rate (percent)
• \( T \) — Tax amount ($)
• \( I \) — Income amount ($)

Explanation: The formula divides the tax paid by the total income and multiplies by 100 to convert to a percentage.

Details: Calculating tax rates helps individuals and businesses understand their tax burden, plan finances, compare tax systems, and make informed financial decisions.
