Deflated by inflation?

Q: How can I find out what inflation’s effect has been over time? — T.W., Strasburg, Va.

A: Try the handy inflation calculator at westegg. com/inflation. It can show you, for example, that something that cost $100 in 2000 would cost $139 in 2015.

To learn the average inflation rate over a period, visit measuringworth. com/inflation. (Between 1980 and 2015, for example, it averaged 3.07 percent annually in the U.S.) That site also shows the inflation rate for specific years. Inflation was less than 1 percent in 2015 — but topped 13 percent in 1980.
