Assuming a couple saves the same amount each year for 32 years before retirement, how would I find how much they need to save in dollars each year in order to produce sufficient cash flows after retirement? Additional information: -They will be retired for 18 years (Their assumed year of death) -Inflation is 3% -Return on investment is 8% Is there a formula I can use? This is for a finance class and I am having extreme difficulty figuring this one out. Thanks very much in advance!! I was really just seeing if anyone knew of a formula i can use to plus in the data, not necessarily have you solve it for me. thanks for the responses though ill check out those sites
