1. What is Effective Tax Rate?

The Effective Tax Rate (ETR) represents the average rate at which an individual or corporation is taxed on earned income. It provides a more accurate picture of tax burden than marginal tax rates by considering the combined impact of federal and state taxes.

2. How Does the Calculator Work?

The calculator uses the Effective Tax Rate formula:

Where:

• \( Federal\ Tax \) — Total federal income tax paid ($)
• \( State\ Tax \) — Total state income tax paid ($)
• \( Total\ Income \) — Gross income before taxes ($)

Explanation: This formula calculates the percentage of total income that goes toward combined federal and state income taxes, providing a comprehensive view of overall tax burden.

3. Importance of ETR Calculation

Details: Understanding your effective tax rate helps in financial planning, tax strategy development, and comparing tax efficiency across different income levels and jurisdictions. It's essential for retirement planning and investment decisions.

4. Using the Calculator

Tips: Enter federal tax amount in dollars, state tax amount in dollars, and total income in dollars. All values must be positive numbers with total income greater than zero for accurate calculation.
