Japan Inflation & Purchasing Power Calculator
The Great Depression (1929–1939) created a paradox: the purchasing power of money technically increased (deflation made dollars worth more), but 25% of Americans had no income at all. Prices fell 25% between 1929 and 1933. Banks collapsed, wiping out savings. President Roosevelt took the US off the domestic gold standard in 1933 and devalued the dollar. A family surviving on $500/year in 1935 was considered lower-middle class — that sum had the purchasing power of roughly $11,000 today, representing extreme poverty.
During the Depression, some American cities issued their own local currency ("scrip") because federal dollars were so scarce. Hundreds of these local currencies circulated simultaneously.
The CPI comparison estimates the purchasing power of ¥20 in 1933 Japan. No wage comparison is shown for this amount and year: same-year wage data may be missing, or the comparison is smaller than half a week. We do not infer a salary, rent period or social class from the nominal amount alone.
1933 was rock bottom for the American economy — 25% unemployment, one in three banks closed, and a new president taking office in March. Franklin Roosevelt's first hundred days launched the New Deal. Germany saw Hitler appointed Chancellor the same month.
¥20 in 1933 is equivalent to approximately ¥311 in 2026. This represents a 1454% increase due to cumulative inflation in Japan between 1933 and 2026.
Since 1933, the Japan currency has lost approximately 94% of its purchasing power. In other words, what cost ¥20 in 1933 would cost ¥311 today — you need 15.5× more money to buy the same goods.
No wage comparison is shown for this amount and year. We only use data recorded for the requested year, and omit comparisons smaller than half a week. Wage data is separate from CPI and remains a legacy estimate.
1933: CPI ≈ 101, linearly interpolated between 1920 and 1950. No annual observation for 1933 is loaded in our dataset; official data may exist elsewhere. The endpoints may include unverified estimates. 2026: CPI 1570, an unverified estimate in the legacy dataset, not a verified official annual observation.
A simple inflation percentage tells you how prices changed, but purchasing power shows you what money could actually buy in human terms. ¥20 in 1933 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.
