1. What Is Effective Tax Rate?

The Effective Tax Rate (ETR) represents the average rate at which an individual or corporation is taxed on their taxable income. It provides a more accurate picture of tax burden than marginal tax rates by considering the overall tax paid as a percentage of total income.

2. How Does The Calculator Work?

The calculator uses the Effective Tax Rate formula:

Where:

• \( \text{Total Tax} \) — Sum of all taxes paid (dollars)
• \( \text{Taxable Income} \) — Total income subject to taxation (dollars)
• \( ETR \) — Effective Tax Rate (percentage)

Explanation: EY calculator uses combined federal and provincial tax rates (e.g., Canada 2025) to determine the total tax liability and calculate the effective rate.

3. Importance Of ETR Calculation

Details: Understanding your effective tax rate is crucial for financial planning, investment decisions, and comparing tax efficiency across different jurisdictions or income scenarios. It helps individuals and businesses better understand their true tax burden.

4. Using The Calculator

Tips: Enter total tax paid in dollars, taxable income in dollars. Both values must be positive numbers, with taxable income greater than zero for accurate calculation.
