Why is my retirement success probability low even though I have sufficient assets?

A low success probability with significant assets usually traces back to one of these inputs in the Retirement planner:

  • Spending too high. Check your spending in the Money in & out tab. A high spending figure will eventually deplete any portfolio.
  • Life expectancy set very long. A longer life expectancy means the simulation has to fund more years of retirement, which lowers success probability even with large portfolios.
  • Income sources missing. Make sure Social Security benefits, pensions, annuities, or rental income are entered in the People and Money in & out tabs.
  • In-retirement risk too conservative. If your in-retirement risk preference is very low, expected returns drop and the portfolio may not keep pace with spending.

To compare which lever moves the needle most for your situation side-by-side, save each variation (different retirement age, contribution rate, spending, or rebalancing frequency) as a what-if scenario and switch between them on the projection chart. Rebalancing frequency itself is adjustable in the Retirement planner calculations.

You can also ask the AI Assistant: "Why is my retirement success probability low and what's the biggest factor I can change?" It analyzes your specific inputs and points to the highest-leverage adjustment.
