Method used

Ordinary annuity, solved for the number of payments

Worked out from IRS Notice 2022-6, Substantially equal periodic payments under section 72(t)(2)(A)(iv) and 4 other sources.

Whether a distribution is permitted, whether any exception to the 10% additional tax applies, and what a series of substantially equal periodic payments must look like to avoid the recapture tax of IRC 72(t)(4) are tax determinations this tool does not make. The withdrawal projections assume a constant rate of return, which no real portfolio delivers. Confirm your position with a qualified tax adviser before acting.

Real rate per period = 0.0040741237836483535
Growth alone supports 25000 a year at this balance
n = -ln(1 - r x balance / withdrawal) / ln(1 + r) = 279.4936513297899 periods
That is 23.291137610815824 years at 12 withdrawals a year
