How the retirement calculator works
We grow your current savings and your monthly contributions month by month at your expected annual return (compounded monthly) until you reach retirement age. The result is an estimate of your nest egg, split into the money you put in and the growth that compounding added on top.
FV = P(1+i)ⁿ + PMT · [ (1+i)ⁿ − 1 ] / i
P = current savings · PMT = monthly contribution · i = monthly return (annual ÷ 12) · n = months to retirement
Why starting early wins
The dollars you invest earliest have the most time to compound, so they do the heaviest lifting. The same monthly contribution started ten years sooner can end up worth far more, often more than double.
Frequently asked questions
How much should I save for retirement?
A common guideline is about 15% of gross income, including any employer match. Use the calculator to check whether your current contribution reaches the nest egg you want.
What return rate is realistic?
A diversified, stock-heavy portfolio has historically averaged roughly 6–7% per year after inflation over long periods. Returns vary year to year and are never guaranteed, so it's wise to be conservative.
Should I count my employer match?
Yes. An employer 401(k) match is free money. Include it in your monthly contribution figure, it's one of the fastest ways to grow your balance.
Does this account for inflation?
The projection is in today's dollars if you enter a return after inflation (a "real" return). If you enter a nominal return, the future figure will buy less than it appears due to inflation.
