Formula
Variables
- Future value of your savings at retirement
- Current savings balance
- Monthly contribution
- Expected annual return rate (decimal)
- Number of months until retirement — years × 12
Enter your current age, target retirement age, current savings balance, monthly contribution, and expected annual return. The calculator compounds your existing savings and adds the future value of your monthly contributions to project your total retirement balance.
Frequently Asked Questions
01How does compound growth help my retirement savings?
Compound growth means your returns earn their own returns. Over decades, this snowball effect dominates: even modest monthly contributions can grow into a substantial nest egg because each year's gains are reinvested and compound on top of previous gains.
02What annual return should I assume?
This calculator uses the annual return you enter. If you want a more conservative projection, lower that assumption or compare several scenarios.
03Does this calculator account for inflation?
No — the result is nominal and does not adjust for inflation.
04Is starting early really that important?
Yes. A 25-year-old investing $300/month at 7% will have more at 65 than a 35-year-old investing $600/month at the same rate. The extra decade of compounding is extraordinarily powerful — it effectively doubles the impact of each dollar saved.
05Does this include employer contributions or tax benefits?
No — enter the total monthly amount you want this projection to treat as contributions. Taxes, employer matches, and account-specific rules are not modeled.
