What is $100 from 2000 worth today?

Using measured US CPI, $100 in 2000 has roughly the same buying power as about $182 today. Prices have risen about 1.8x since 2000, so it takes 1.8 times as many dollars to buy the same goods. The exact figure updates with the latest CPI release; switch the calculator to any country to use that country's own index.

How is the inflation value calculated?

Between two years that both have published CPI data, the calculator uses the ratio of the two years' Consumer Price Index values, which captures the inflation that actually happened. For future years (or years before the data begins) it falls back to your assumed annual rate, compounded as (1 + rate) raised to the number of years. It never uses simple, non-compounding inflation.

How much should my salary increase to keep up with inflation?

At minimum, your salary needs to grow by the annual inflation rate every year just to stand still. At 6% inflation, a salary that doesn't rise loses about 44% of its buying power over 10 years. A raise below the inflation rate is a real-terms pay cut even though the number on your payslip went up.

What will 1 lakh (or $1,000) be worth in 20 years?

If inflation averages 6%, the buying power of ₹1,00,000 today shrinks to about ₹31,000 in today's money after 20 years, so you'd need roughly ₹3,20,000 then to buy what ₹1,00,000 buys now. At 3%, $1,000 would need to become about $1,806 over 20 years to hold its value. Use the Today→Future mode to run your own figure.

Value Over Time (2005-2026)

Equivalent amount rises with prices; buying power shows what a fixed $500,000 would feel like in 2005 money as years pass.

What this means

Prices rose 1.86x over 21 years, money lost about 46% of its buying power.
The same goods cost $930,147 versus $500,000, an average of 3.0% inflation a year.

How We Work It Out

Money is converted between two years using compound inflation, never simple inflation:

When both years have CPI data (measured):

Value(to) = Value(from) × CPI(to) / CPI(from)

Otherwise, with an assumed annual rate i:

FV = PV × (1 + i)ⁿ and PV = FV / (1 + i)ⁿ

Where n = number of years between the two points and i = the annual inflation rate. The CPI ratio is preferred because it reflects the inflation that actually occurred rather than a flat assumption.

Real-World Examples

The same math on a salary

A salary of $500,000 in 2005 matches about $803,095 today. If your pay grew more slowly than that over the last 19 years, your buying power fell even though the number rose.

Rule of 72: how fast prices double

At 3% inflation, prices double roughly every 24 years. Over the 19 years this page covers, that compounding, not any single year's inflation, is what drives the gap between $500,000 and $803,095.
