United States Inflation & Purchasing Power Calculator
World War II brought government control of prices and widespread rationing across the Allies. While official inflation was suppressed, the real purchasing power of money was constrained by what was available to buy. The 1944 Bretton Woods Agreement established the US dollar as the world's reserve currency, pegged to gold at $35/oz. By 1945, US war production had created full employment and rising wages. The post-war baby boom and GI Bill created the modern middle class — home ownership rose from 44% to 55% within a decade.
During WWII rationing in the UK, the average family's food budget was fixed at approximately 1 shilling per person per day — leaving almost nothing for other expenditure.
The CPI comparison estimates the purchasing power of $20 in 1945 United States. 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.
1945 ended WWII. Victory in Europe in May, atomic bombs on Japan in August. The postwar order was being drafted at Bretton Woods, the UN at San Francisco. The US held around half of world manufacturing capacity. Everywhere else, cities were ruins.
$20 in 1945 is equivalent to approximately $364 in 2026. This represents a 1718% increase due to cumulative inflation in United States between 1945 and 2026.
Since 1945, the United States currency has lost approximately 94% of its purchasing power. In other words, what cost $20 in 1945 would cost $364 today — you need 18.2× 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.
1945: CPI 18, published BLS annual average (not interpolated). 2026: CPI 327.2, 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 1945 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.
