This free inflation calculator shows what money from any year is worth in another, in 187 countries, by each country's own consumer price index. Switch it around and it shows what today's prices become years from now.
I built it because a dollar, a peso or a lira loses value at very different speeds, and that matters the moment you earn in one currency and spend in another.
The calculator reads the World Bank's price index for each country and the US Bureau of Labor Statistics' index back to 1913.
Here's how inflation is measured, what it did to money in the US and around the world, and how to keep your savings ahead of it.
TL;DRKey takeaways
What is an inflation calculator?
An inflation calculator compares money across years by how much prices changed in between. It uses a consumer price index, which tracks what a fixed basket of everyday goods and services costs each year.
If the index is 100 in one year and 150 in another, prices rose 50%, and $100 then buys what $150 buys later. The calculator does that for any two years in its data.
How to use the inflation calculator
It has two modes: looking back, and looking ahead.
The price data loads once from my site, and your numbers never leave this browser.
Where the numbers come from
Every country uses its own price index, from the official source that publishes it.
| Data | Source |
|---|---|
| US prices back to 1913 | Bureau of Labor Statistics, CPI-U, yearly averages |
| 186 other countries | World Bank, consumer price index |
| This year in the US | The latest month published so far |
The World Bank publishes each year's index after the year ends, so most countries run to 2025. October 2025 is missing from the US series, so 2025 averages the 11 months the Bureau published.
What $100 is worth today in the US
Here's what $100 from each year buys in 2025, by the US index.
| $100 in | Buys what this buys in 2025 |
|---|---|
| 1913 | $3,257.44 |
| 1950 | $1,337.71 |
| 1970 | $829.22 |
| 1980 | $390.67 |
| 1990 | $246.40 |
| 2000 | $186.96 |
| 2010 | $147.64 |
| 2020 | $124.39 |
The steepest single years were 1917 at 17.8% and 1918 at 17.3%, during the First World War, and 1947 at 14.4%, right after the Second. The calculator marks the steepest year in whatever span you pick.

The same 10 years look very different depending on where you hold your money. Here's what 100 in each country's own currency in 2015 equals in 2025.

Panama, where I've been a permanent resident since 2020, uses the US dollar and still saw prices rise far less than in the US. That's the kind of difference the calculator makes easy to see before you move.
The currency converter shows what those currencies are worth against each other today, and tax rates by country shows what you'd keep.
A worked example
Here's the example the calculator loads when you press Try an example.
You have $100 from 1990 in the US. In 2025, it buys what $246.40 buys, because prices rose 146.4% in those 35 years.
That's about 2.6% a year on average. It sounds small, but it more than halved what a dollar from 1990 buys.
Now switch to the future mode. At 3% a year, what costs $100 today costs $134.39 in 10 years.
What inflation means for your money
The Federal Reserve aims for 2% inflation over the longer run. So even when it does its job, a dollar loses about a third of its buying power every 20 years.
Cash loses value every year
Money in an account paying less than inflation buys less each year, even as the balance grows. Keep what you'll need soon in cash, and put long-term money where it can grow faster than prices.
Your returns are only real after inflation
A 7% return with 3% inflation is about 3.9% in real terms. The compound interest calculator and the retirement calculator both take inflation out for you.
Your raise should beat it
A 3% raise in a year of 3% inflation is no raise at all. Use the past mode to check what your old salary is worth today.
Mistakes to avoid
These are the common ways inflation gets misread.
- Comparing old and new prices without adjusting either
- Reading one year's spike as the long-run rate
- Using your home country's inflation for money you'll spend somewhere else
- Treating a growing balance as growing wealth without checking the real return
Pick the country where you'll spend the money, and the calculator does the rest.
Who is the inflation calculator for?
It's for anyone with savings, a salary or a plan that runs over years, and these tools pair with it.
- Compound interest calculator – for growing your money faster than prices
- Retirement calculator – for planning a retirement in today's money
- Currency converter – for comparing what currencies are worth today
- Tax rates by country – for weighing where to live and earn
- Hourly to salary calculator – for checking what your pay is really worth
Check your own country first, then the country you're thinking of moving to.
