Retirement Savings Calculator
Note
This calculator assumes compound growth with monthly contributions. Actual results may vary.
Forecast retirement account growth using current savings, recurring contributions, and expected return assumptions.
Formula
Worked Example
Current age40
Retirement age65
Current savings$85,000
Monthly contribution$1,000
Expected annual return6.5%
Result: $1,159,191 at 65
The $85,000 already saved grows to about $410,000 over 25 years at 6.5%. The $300,000 of monthly contributions grows to about $749,000, so roughly two-thirds of the final balance is investment growth. The result is in future dollars; at 3% inflation it is worth about $554,000 today.
Frequently Asked Questions
Should contribution growth be included?
Yes. If your contributions rise with income, your end balance may be materially higher than a flat-contribution projection.
Is this a guaranteed outcome?
No. Returns vary year to year. Treat projections as planning ranges, not precise guarantees.
