How Retirement Income Requirement Calculator Works?

The Retirement Income Requirement Calculator sets an income target as a share of today's income. It grows that target with inflation before and during retirement.

  1. Enter current income

    Type today's yearly income.

  2. Set the replacement ratio

    Type the share of income to keep, such as 75%.

  3. Enter years to retirement

    Type the years until retirement starts.

  4. Enter inflation

    Type expected inflation to project future-dollar needs.

Retirement Income Requirement Calculator Formula

The Retirement Income Requirement formula multiplies today's income by the replacement ratio and by inflation compounded to the target year.
