Estimate how much you could have saved by the time you retire. Enter your current age, your target retirement age, the amount you have saved so far, how much you add each month and the annual return you expect, and the calculator projects your balance at retirement using monthly compounding. It shows the total you contribute over those years and how much of the final figure is investment growth. Seeing the projected nest egg helps you sanity-check whether your current savings rate is on track or whether you need to save more or work longer. Returns are assumed steady and inflation, taxes and fees are not modelled, so use it as a planning guide. All calculations happen locally in your browser.
