About Inflation
Inflation is a quick, slightly startling lesson in how much money has changed. Each round shows a real, documented US price from decades ago · a loaf of bread for 12 cents in 1950, a gallon of gas for 36 cents in 1970 · and asks what that price is worth in today's money. Four choices; pick the closest.
The answer is real maths, not a guess. When you choose, the game shows the true figure, worked out from the actual US Consumer Price Index: the old price multiplied by today's CPI divided by the CPI of that year. So a 1950 dollar really is worth more than ten of today's dollars, and you can see exactly why.

FAQ
-
How is the answer worked out?
Each round takes a documented historical price and multiplies it by today's Consumer Price Index divided by the CPI of the price's year · the standard way economists convert old money into today's money. The game shows you the multiplier. -
Are the old prices real?
Yes · they are widely-cited average US prices for their year (a loaf of bread, a movie ticket, a gallon of gas, a new car, and so on), and the CPI figures come from the US Bureau of Labor Statistics. -
Why is a 1950 dollar worth so much more now?
Because prices have risen almost every year since, and the increases compound. The US CPI has multiplied roughly thirteen-fold since 1950, so a 1950 dollar buys about what thirteen dollars buy today. -
Is this in US dollars?
Yes · the prices and the CPI are American, so the figures are in US dollars. The underlying idea · that inflation makes old money worth more in today's terms · is the same everywhere. -
