Sequence risk is missing
Real portfolios do not earn the same return every year. Bad early returns can shorten portfolio longevity even if the average return looks acceptable.
Example
With a 500,000 starting balance, 30,000 annual withdrawals and a constant 4% return, the calculator projects year-by-year until the balance is depleted or can sustain the withdrawal.
How to use the result
Test several return and withdrawal assumptions. A plan that works only under optimistic returns may need lower spending, more savings or a longer work period.
Limitations
This is not retirement, tax or investment advice. It does not model inflation adjustments, market volatility, taxes, fees, pension income or changing spending needs.
