Longevity Scenario Calculator
See how sensitive your retirement funding is to how long you actually live, by comparing a shorter, expected, and longer planning horizon.
Shorter than planned (25 years)
Funds last the full horizon
$1,185,233
As planned (30 years)
Funds last the full horizon
$1,056,555
Longer than planned (35 years)
Funds last the full horizon
$800,010
How it works: the same portfolio, withdrawal rate, return, and inflation assumptions are run through the retirement-income engine at three durations — five years short of your planning horizon, at it, and five years beyond — so you can see funding sensitivity to longevity risk directly.
Limitations: uses a constant assumed return every year, same as the Retirement Income calculator — see the Sequence-of-Returns Risk calculator for what that doesn't capture.
