Worked example result

Years to retirement	10
Projected savings at retirement	$27,070
Total you contribute	$10,000
Growth from investments	$17,070

$10,000 growing at 10% for 10 years becomes about $27,070 with no further contributions — growth of $17,070.

Estimate how much you could have at retirement: your current savings plus monthly contributions, grown at an assumed annual return, compounded monthly.

The projection is an estimate, not a guarantee — real returns vary year to year. Use it to test how changing your monthly contribution or retirement age changes the outcome.

The formula

Balance = S(1+r)^n + C · ((1+r)^n − 1)/r, over n = months until retirement

Worked example

$10,000 growing at 10% for 10 years becomes about $27,070 with no further contributions — growth of $17,070.

Frequently asked questions

What return should I assume?

Long-run US stock market returns have averaged around 7–10% per year before inflation, but past performance does not guarantee future results. Many planners use 6–7% for a mixed portfolio.

Does this account for inflation?

No — results are in nominal dollars. To think in today's purchasing power, subtract roughly 2–3% inflation from the return you enter.
