Use this free retirement savings calculator to project how much your nest egg could grow by the time you retire — and roughly how many years it might last once you start drawing it down. Enter your current savings, monthly contributions, and expected return to see your estimate update instantly.
The “years it could last” figure is simplified — it divides your projected balance by your annual withdrawal and ignores any growth, inflation, taxes, or pensions after retirement.

How to use this retirement savings calculator
Enter your current savings, what you add each month, your current and retirement ages, and a realistic annual return. The tool compounds your balance month by month until retirement using the future-value formula, then estimates how long the money could last by dividing it by your expected yearly withdrawal. Every field recalculates the moment you change it, so try a few scenarios.
Why compounding and your time horizon matter
The earlier and more consistently you contribute, the more compound growth works in your favor — returns earn returns over time. Even small changes to your monthly contribution or your retirement age can shift the projected balance significantly. Because markets fluctuate and the drawdown estimate ignores inflation and taxes, treat these numbers as a planning guide rather than a guarantee.
