Zero return, fixed withdrawals
A 12,000 balance with 1,000 withdrawn monthly and no growth or yearly withdrawal increase is exhausted in month 12. Total withdrawn is 12,000.
Explore how a starting balance changes under repeated withdrawals and a constant assumed return. See a possible depletion month and a capped final withdrawal.
Simulate monthly withdrawals from a balance at a constant effective annual return. Optionally increase the withdrawal once each year, beginning in month 13.
The last withdrawal is capped at the available balance.

Monthly return = (1 + annual return)^(1/12) − 1. This assumes smooth growth and ignores taxes, fees, market volatility, sequence of returns, and required distributions. It is not a retirement adequacy or safe withdrawal assessment.

A 12,000 balance with 1,000 withdrawn monthly and no growth or yearly withdrawal increase is exhausted in month 12. Total withdrawn is 12,000.
A 2,500 balance with 1,000 monthly withdrawals at 0% provides two full withdrawals and a final 500 withdrawal in month three.
The monthly growth factor is the twelfth root of one plus the effective annual return. For month-end withdrawals, growth applies to the opening balance before withdrawing. For month-start withdrawals, the withdrawal comes first and only the remaining funds receive that month’s growth or loss.
The initial withdrawal applies to months 1 through 12. It is multiplied by one plus the increase rate for months 13 through 24, and again each year after that. The increase can represent a chosen inflation assumption, but it is not tied to actual CPI data.
The same average return can produce very different outcomes when losses happen early rather than late. This simulation smooths all returns and does not test volatility or a range of market paths. A balance remaining at your selected horizon says only that it remains in this particular arithmetic scenario.
The withdrawal is capped at available funds. The balance becomes zero, the simulation stops, and the last scheduled withdrawal may be smaller than requested.
No. That result only describes the selected horizon, up to 100 years. Longer withdrawals, changing returns, taxes, and fees may change the outcome.
Yes. An effective return as low as −99% is accepted, converted to an equivalent monthly rate. This is a smooth loss assumption rather than market behavior.
