Enter the individual’s income and the national average income into the calculator to determine the Income Index. This calculator can also evaluate any of the variables given the others are known.

Income Index Formula

The following formula is used to calculate the Income Index.

II = (I / N) * 100

Variables:

• II is the Income Index (%)
• I is the individual’s income ($) • N is the national average income ($)

To calculate the Income Index, divide the individual’s income by the national average income. Multiply the result by 100 to get the Income Index in percentage.
