How long will your money last in retirement?

Calculating How Long Retirement Money Will Last

When figuring out how far your money will take you in retirement, you need to consider a number of different factors. For one thing, you need to think about how much you're withdrawing from your retirement nest egg each year. If you're planning to be retired for 25 to 30 years, the figure most experts say you can safely take out of your investments annually is in the 4 percent range [source: MSN Money]. When you think about how much you'll need to withdraw each year, consider not only budgetary staples like your mortgage and the cost of food. Make sure you also take the time to think about nonessentials like travel, not to mention how much you spend on health care -- which is becoming more and more expensive. By one estimate, someone who retires at age 65 today and lives to age 90 will spend about $180,000 for medical costs alone [source: Bloomberg Businessweek].

Asset allocation is another major factor that will determine the size of your nest egg. Where you put your money can determine how long it lasts. Investing in the stock market can be a riskier endeavor than bonds, CDs or leaving your money in cash, but it can also pay off with a much higher rate of return. Experts say you need to leave at least 50 percent of your portfolio in stocks to garner returns high enough to offset the cost of inflation and keep your annual withdrawal at 4 percent [source: MSN Money].

Retirees also need to consider the rate of inflation. A dollar today doesn't stretch nearly as far as it did when you were younger. Remember when you could buy candy for a penny, or a slice of pizza for a quarter? Today, a candy bar will set you back more than a buck, and a slice of pizza can top $3. Inflation is rising by an average of 3 percent annually -- and that means your retirement funds are buying 3 percent less each year [source: Bureau of Labor Statistics]. In other words, you'll have to give yourself an annual raise to make up for rising inflation.

Luckily, other sources of income can offset any shortcomings in your retirement plan. Social Security won't get you very far alone -- in fact, the average Social Security check in 2011 was just over $1,100 a month [source: US News and World Report]. What's more, pensions are quickly becoming extinct. That said, you can make your retirement dollars stretch farther by lowering your cost of living, getting an annuity, or picking up a part-time job.

If you're not sure whether you're saving enough, several Web sites have set up useful calculators to help you evaluate your retirement dollars. T. Rowe Price's Retirement Income Calculator can help you figure out how much you can safely spend each month, and how long your retirement dollars will last. Smart Money's calculator can also help you determine how long your investments will last, based on your portfolio value and the inflation rate.
