Frequently Asked Questions
How does inflation erode money?
Inflation compounds like interest in reverse. At 3 percent inflation for 10 years, prices rise by a factor of 1.03^10, about 1.344, so cash kept idle buys roughly 26 percent less.
What inflation rate should I use?
Long-run averages are around 2 to 3 percent in the US and UK, though specific categories like housing, food and education often inflate faster than the headline rate.
How can savings beat inflation?
Money must earn a return above the inflation rate to grow in real terms. Cash under the mattress loses value every year, while invested assets have historically outpaced inflation over long periods.
