How Retirement Savings Are Projected

Future value = savings × (1 + r)ⁿ + monthly × ((1 + r)ⁿ − 1) ÷ r
Today’s dollars = future value ÷ (1 + inflation)^years

r is the monthly equivalent of the yearly return. Showing results in today’s dollars makes the goal easier to judge.

Worked Example

Tips

Returns vary year to year, and a bad stretch just before retirement matters most. Social Security and pensions reduce how much you need to save. Revisit the plan every year or two.
