United States Inflation & Purchasing Power Calculator
The 2010s saw official inflation remain historically low — averaging just 1.8% annually in the US — but purchasing power erosion was far from absent. Asset prices (homes, stocks) soared while wages for most workers stagnated. A dollar's official CPI purchasing power barely changed, but the cost of a home relative to income hit record highs. Healthcare costs rose 30% faster than general inflation. College tuition tripled in real terms over two decades. The 2010s demonstrated that CPI can understate the cost-of-living pressures felt by ordinary households.
Between 2010 and 2020, US median home prices rose 62% while median wages rose just 23% — meaning a home was 30% more expensive relative to income than at the start of the decade.
$20 in 2015 sat firmly in everyday-spending territory — the scale of groceries, a tank of fuel, or a meal out rather than anything a household would budget around. Sums like this are where inflation is felt first, because they recur weekly and small price changes compound fast.
The average annual wage in United States in 2015 was approximately $41,674. A loaf of bread cost approximately $2.79 and monthly rent averaged around $820.
$20 in 2015 is equivalent to approximately $27 in 2026. This represents a 37% increase due to cumulative inflation in United States between 2015 and 2026.
Since 2015, the United States currency has lost approximately 27% of its purchasing power. In other words, what cost $20 in 2015 would cost $27 today — you need 1.4× more money to buy the same goods.
This helps illustrate not just the nominal price change, but what money actually meant in human terms — how long people had to work to earn it.
This calculation uses official Consumer Price Index (CPI) data for United States. 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.
A simple inflation percentage tells you how prices changed, but purchasing power shows you what money could actually buy in human terms. $20 in 2015 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.
Want to flip the question? Instead of asking what $20 was worth in 2015, ask what your modern salary would have made you in that era. Our Rich-O-Meter takes any annual salary and shows where it would have ranked — working class, middle class, or wealthy elite — at any point in United States's recorded history.

Beyond history, there's geography. Our WealthMap compares your current salary to median income in around 90 countries today. A middle-class income in one country is wealthy-elite in another — and the gap between these places is often wider than the gap between eras.
