<p>One common rule of thumb is that you can take 4% of your assets out in the first year of retirement, then increase this amount by the rate of inflation every year. Assuming that you will be retired for 30 years or so, this approach supposedly has you run out of money before you die in only something like 10% of the scenarios they’ve run, based on historical experience.</p>
<p>Another way to go is to get quotes on immediate annuities. How much do you need to invest today to get an annuity that is large enough (and inflation indexed) for you to live in retirement? This way, you don’t have to worry about outliving your money, but you will leave little or nothing for your heirs (except, perhaps, having paid for their college education!)</p>
<p>I think one of the most difficult things to calculate is how much you will (want) to spend in retirement. Many guidelines say you will need only 70 - 80% of your pre-retirement income. This is based on many surveys, which show that retires do, on average, spend 20-30% less in retirement. But it is not clear that they spend less by choice, or because they don’t have as much money as they would like.</p>
<p>In one retirement seminar my wife and I took, they talked about 3 phases of retirement: the go-go years, the slow-go years, and the no-go years. In the go-go years you may want to do a lot of travel, or take the vacations you were never able to schedule or take when working. In this initial period of retirement, your spending may well be higher than it was when working. As your energy level and health status diminish over time, your non-medical spending will go down, but your medical spending may go up.</p>
<p>One other thing for the OP’s friend to consider is what SS benefit she is entitled to. She may not be entitled to any SS benefit under her own work record if, for example, she never worked outside the home. You need, I think, 10 years of covered employment before you are eligible for any SS benefit, and with only 10 years the benefit is rather low. She may, on the other hand, qualify for a SS benefit based on her spouse’s work record. She should probably talk to a good financial planner who is knowledgeable about SS rules and regs - they are very complicated.</p>
