How Long Will My Superannuation Last?
This calculator estimates how many years a retirement balance might support a chosen annual income, assuming the remaining balance keeps earning an investment return while your income increases with inflation each year.

How the drawdown is modelled
Starting from your retirement balance, the calculator subtracts your chosen annual income and adds your assumed investment return each year, then increases the income amount by your assumed inflation rate for the following year — repeating until the balance reaches zero or comfortably outlasts a long retirement. The year-by-year table below the results shows exactly how the balance moves so you can see whether it grows for a while before declining, or declines from day one.
Why a higher income draws the balance down faster than it looks
Because income increases with inflation every year while your balance only earns your assumed investment return, a return that's lower than your income needs will draw the balance down noticeably faster in later years than in early ones. Small changes to the annual income figure or the investment return assumption can change the "lasts to age" result by several years, so it's worth testing a few scenarios rather than relying on a single result.
