i used the online calculator.


i did end of time period first and then beginning of time period.
i also did 2% per year and 2% per month because it wasn't clear whether you meant at 2% per year compounded monthly or at 2% per month.


following are the results.


first is end of month withdrawals at 2% per year compounded monthly.
withdrawal = 2482.50 per month.
