How Inflation Affects Your Financial Future

US News

People retiring today can expect to live another 20 years, according to Social Security figures. But in making our financial plans, we have to account for 30 more years, since roughly one in five of us will live past age 90.

Once you're retired, you live on a fixed income. There are no more raises, bonuses or employer contributions to your retirement plan. Even if you can afford your lifestyle today, you have to worry about what's going to happen over the next 30 years as prices inevitably climb, some years more than others. Will Social Security keep up? Will your investments produce enough income?

Think of what happened over the last 30 years. In 1983 the average college tuition was less than $4,000 a year. Today it's over $23,000 a year. The cost of college is up 600 percent. At that rate, in 30 years average tuition will be well over $100,000 a year, while top private colleges will charge two or three times that much.

If your kids are grown up, you no longer have to worry about college tuition. But you do have to worry about medical costs. According to Bloomberg, medical expenses have also increased 600 percent in the last 30 years. And hospitals have given us an even bigger dose of inflation. Back then a typical five-day stay in a hospital cost around $600. Now it averages $20,000. At that rate, by the time we're 90 the cost of a hospital stay will top half a million dollars.

My wife and I are thinking about relocating in retirement, so we've been looking at real estate prices. The house we now live in is worth, according to zillow.com, roughly $550,000, which is about average for a suburban home in the Northeast. But when the place was built, some 30 years ago, it sold for less than $70,000. That's an eight-fold increase, even accounting for the recent slump in real estate. If you want to buy this house in 30 years it might cost over $4 million.

I don't want to scare you too much. According to CNN, for the last 30 years college tuition, medical fees and housing costs have all gone up faster than the general rate of inflation. The Consumer Price Index - the price for an average basket of goods and services - sits at a more modest 235 percent level compared to 1983. Whatever cost $100 back then now costs $235.

Some items have gone up less than inflation. I recall buying a Toyota Camry in 1984. It set me back about $12,000. Today that car costs around $22,000, or less than twice what it did 30 years ago - and it's a better car. The price of most foods, from milk and eggs to coffee and alcohol, have also gone up less than inflation.

In 30 years, if I'm alive at all, the only people interested in the value of my house will be my heirs. But I might still want to drive my old Toyota, and I'll want to eat or mail some Christmas cards or help my grandchildren pay for college. If prices continue for the next 30 years the way they have in the past, then a gallon of milk or a box of cornflakes will still be under $10, but a gallon of gas will gear up to $12 and a book of stamps will stick you for $21. If your genius grandchild wants to go to Stanford, the price will be well over $1 million.

Meanwhile, next year's increase in Social Security is all of 1.5 percent. That follows a 1.7 percent increase for 2013, a 3.6 percent increase in 2012 and no increase in either 2010 or 2011. It's not much, but it's something.

Your investments will probably go up more. In November 1983 the Dow Jones Industrial Average sat around 1,250. Now it's bumped up to 16,000 - a more than 12-fold increase. According to Fidelity Investments, for workers "age 55 or older who have been active for at least ten years, the average 401(k) balance is now $269,500." All other things being equal, that balance will top $3 million in 30 years.

Of course, there's no guarantee that the next 30 years will bring inflation or stock market gains like the last 30 years. But forewarned is forearmed: You must take inflation into account as you plan for your future. Meanwhile, look at the bright side - at least we'll be able to afford to eat a decent breakfast.
