What is retirement calculator?
Enter your current age, target retirement age, current savings, monthly contribution, expected return, and (optionally) an annual raise on contributions and an inflation rate. The calculator projects your balance year by year, and shows the final balance in both nominal and real (today's-dollar) terms.
Useful for sanity-checking your 401(k) or IRA plan, comparing scenarios, and answering the "am I on track?" question. Run a few scenarios with different contribution amounts to see how each extra $100/month changes the outcome.
For the pure-math version (no age framing, no inflation, no raises), see the compound interest calculator.
