thank you all. FYI our company does not have inflation adjustment
I just found out there is a 6% rule. Here is: a monthly pension of $1,000 (beginning at age 65) or a lump sum offer of $160,000. If you annualize the monthly payment ($12,000) and divide it by $160,000, you get 7.5%—which is the return you’d need to earn every year (on your lump sum payment) to match the value of the monthly payment offer. As S&P returns averaged under 7% from 2000-2021, earning an annual average of 7.5% is perhaps a daunting task.
