Reader Question - I am 67 years old and would like to start drawing down my RRIF. I do not want to wait until 71. I also do not want to be stuck with any pre-set standard tax formulas of 4 or 5% per year or maximum or minimum withdrawals in retirement.
I simply want to withdraw $500 a month, every month. I have $110K. How long will my money last?
Thank you for that more often than not question of how long will my money last in retirement?
All I or we can to is estimate how long this money will last you based on some simple assumptions. Let's assume you earn 7% annual return on the remaining balance after the $500 a month withdrawal. Also assuming you make the withdrawal at the beginning of each month.
Calculation
Calculate the mo. interest rate then divide by 12.
7%/12 = 0.5833%
as a decimal = 0.005833
Calculate the remaining balance after the first withdrawal then subtract the $500 from the initial balance.
$110,000-$500= $109,500
Calculate the Interest earned on the remaining balance by the monthly interest rate. $109,500* 0.005833 = $638.20 (approx)
Calculate the new balance after adding the interest; Add interest earned to remaining balance.
$109,500 + $638.20
=$110,138.20
Repeat the above steps 2-4 for the subsequent months until the balance is depleted or reaches a negligible amount.
Timeline
Based on this calculation, if you continue to make $500 withdrawals at the beginning of each month and earn a consistent 7% annual return, it's estimated that the funds will last approximately 21 years and 5 months.Please note that this calculation does not account for taxes or inflation and assumes a constant rate of return of 7%. This is simply a rough estimate to show you where you stand now and what you can look forward to.
