About the numbers
Methodology & Data Sources
Real Millionaire asks a simple question: how much money would you need today to have the same purchasing power as $1 million in 1795, when the word ‘millionaire’ first became popular?
The short version
We start with $1,000,000 in 1795 and adjust it for more than two centuries of US consumer price inflation. The result is today’s Real Millionaire threshold: currently about $26,735,979.
Step 1 — 1795 to 1913: historical estimates
Official US consumer price statistics only begin in 1913. For earlier years we use reconstructed historical consumer-price estimates published by MeasuringWorth. Comparing the 1795 and 1913 price levels gives a single historical multiplier.
This value is stored in our settings and read from there, so any verified correction is applied automatically everywhere on the site.
Step 2 — 1913 onward: official BLS CPI
From 1913 we use the official Consumer Price Index published by the US Bureau of Labor Statistics:
- Series CUUR0000SA0
- CPI-U, All Items, U.S. City Average, Not Seasonally Adjusted
- 1913 reference: the average of the twelve monthly 1913 values (9.8833)
- Latest official CPI used: 334.98 (August 2026)
The formula
Why the number keeps ticking
The BLS publishes CPI once a month. Between releases, the large number on our homepage grows smoothly using the latest 12-month inflation rate (currently 3.4%). That continuously ticking figure is therefore an estimate; it is reset to the official calculation each time a new CPI value is published.
The Real Millionaire Factor
For each person in our rankings we show how many Real Millionaires their fortune represents:
The factor is calculated live from the current threshold and rounded to the nearest whole number.
