1. What is the Family Income Percentile Calculator?

The Family Income Percentile Calculator estimates where a household's income falls compared to other households of the same age group in the population. It helps understand economic standing relative to peers.

2. How Does the Calculator Work?

The calculator uses income distribution data:

Where:

• \( Income \) — Annual household income (USD)
• \( Age \) — Age of primary earner (years)
• \( Lookup\_table \) — Reference data for income distribution by age group

Explanation: The calculator compares your income to national income distribution data for your age group to determine your percentile ranking.

3. Importance of Income Percentile Calculation

Details: Knowing your income percentile helps with financial planning, understanding economic mobility, and assessing your position in the income distribution.

4. Using the Calculator

Tips: Enter your total annual household income in USD and the age of the primary earner. Use pre-tax income for most accurate comparisons.
