This page is designed to help you find out whether RealWorth.io is good and if it is the right choice for you.
RealWorth.io is a free historical inflation and purchasing power calculator that goes beyond a single adjusted number. Enter any amount, pick a year and a country, and it shows what that money actually meant in everyday terms: how many weeks of work it cost, how many loaves of bread it bought, how many months of rent it covered. It covers six countries (USA, UK, Germany, France, Canada, and Japan) with official CPI data going back to 1750, sourced from the Bureau of Labor Statistics, the Bank of England Millennium Dataset, Destatis, INSEE, Statistics Canada, and the Statistics Bureau of Japan. Every calculation documents its sources and methodology. Where most inflation calculators stop at "X in 1920 equals Y today," RealWorth.io adds the human context that makes the number mean something. A $3,000 salary in 1960 is just a figure until you see it as a share of the median wage of the time. Beyond the core calculator, RealWorth includes: The Story of Money, an interactive page tracing a single coin through 5,000 years of currency, from cowrie shells to paper dollars. How Big Is a Billion Dollars, a visual tool that turns an abstract number into a physical road you can drive along, where every tile is a $100 bill. The Rich-O-Meter, which ranks any salary against historical income levels. The WealthMap, which compares your income against today's global medians so you can see where you'd count as "rich" around the world.

Most inflation calculators stop at a multiplier - "$100 in 1920 = $1,636 today" and leave it there. RealWorth translates that number into things you can actually picture: how many weeks of an average salary it was, how many loaves of bread, how many months of rent. It covers 6 countries (USA, UK, Germany, France, Canada, Japan) back to 1750, all from official CPI data, and pairs the calculator with visual tools like The Story of Money and How Big Is a Billion Dollars.
Next.js (App Router), TypeScript, and Tailwind CSS, deployed on Vercel. Data pipelines run on GitHub Actions and pull from official sources like the World Bank, FRED, and national statistics agencies. Visualizations use D3 and React.
Because it answers "what did that money actually mean?" instead of just "what's the multiplier?" Competitors give you a number; RealWorth gives you context - wages, bread, and rent for the era, plus historical background on each year. It's completely free, has no signup and no paywall, covers 6 countries in one place, and the data comes straight from official statistical sources (BLS, Bank of England, Destatis, INSEE, StatCan, Japan's Statistics Bureau).
Anyone curious about the real value of money over time: students and teachers of history and economics, journalists and writers who need historical price context, genealogy and history enthusiasts, and everyday people wondering what an old salary, price, or inheritance would be worth today.
RealWorth started from a small frustration: every inflation calculator answers "what is old money worth today?" with a single number and stops there, as if a multiplier were the whole story. The interesting part is always underneath — whether a sum was a week of wages or a year of them, whether it paid the rent or barely bought dinner. RealWorth was built by one person to put that human context back into the numbers, and it has grown from a calculator into a broader visual hub for understanding money.
RealWorth is a free public tool rather than a B2B product, so it has users rather than customers — students, teachers, journalists, and history enthusiasts worldwide.
