Jazz Age Prosperity, German Hyperinflation, and the Consumer Economy
The 1920s were a decade of extremes. In the United States, the "Roaring Twenties" saw unprecedented consumer prosperity — the first mass market for cars, radios and household appliances. Real wages rose significantly and credit became widely available for the first time. Yet in Germany, 1923 brought the most dramatic hyperinflation in modern history: a loaf of bread cost 200 billion marks at its peak. A wheelbarrow of cash couldn't buy a newspaper. This destroyed the life savings of an entire generation and permanently shaped German attitudes toward inflation and monetary stability.
At the height of German hyperinflation in November 1923, the exchange rate was 4.2 trillion marks to 1 US dollar. Workers were paid twice daily so they could spend wages before they lost their value.
¥10 as a modest sum
¥10 in 1920 was a real amount of money, but not a fortune. A working family could plan around it. This kind of sum might cover a month's essentials for a single person, or a week of household supplies for a larger family. It sat in the range where ordinary people made ordinary decisions — save it, or spend it on something useful.
What was happening in 1920
1920 was the first full year after WWI, and the world was reeling. The 1918 flu pandemic had finally subsided after killing perhaps 50 million people. Prohibition began in the United States. Germany's mark was already unstable, foreshadowing the hyperinflation of 1923.

How accurate is this inflation calculation for 1920?+
This calculation uses official Consumer Price Index (CPI) data for Japan. For years before 1913 (USA) or equivalent periods for other countries, the calculation uses reconstructed price indices from academic sources including MeasuringWorth.com and the Bank of England's Millennium Dataset. Pre-industrial calculations carry a wider margin of uncertainty.
Why does purchasing power matter more than just inflation percentage?+
A simple inflation percentage tells you how prices changed, but purchasing power shows you what money could actually buy in human terms. ¥10 in 1920 bought a specific number of loaves of bread, weeks of rent, or months of wages — context that makes the number real and tangible, not just an abstract percentage.
