Why cash loses value over time, how to think in real returns and what you can do about it.
What inflation does
Inflation is the general rise in prices. When it runs at 3 percent a year, something costing $1,000 today costs about $1,344 in ten years.
Real vs nominal returns
A nominal return is the headline rate. A real return is what is left after inflation. If your account pays 4 percent and inflation is 3 percent, your real return is only about 1 percent.
The cost of idle cash
Cash held with no interest loses value every year. At 3% inflation, $1,000 kept under the mattress would buy only what about $744 buys now after ten years.
Protecting your money
Keep emergency money in interest-bearing accounts. For long-term goals, many people use diversified investments that have historically beaten inflation, accepting that values can fall in the short term. Some governments also offer inflation-linked savings products.
Plan with it in mind
Use realistic inflation rates when you set goals. The inflation calculator shows what future costs might look like.
A balanced view
Do not panic about inflation, and do not ignore it. Review your savings rates once or twice a year.
