Inflation Calculator
See how inflation reduces the value of money over time.
💸 $1000 today at 3% inflation is worth less each year. In 10 years you'd need $1,344 to buy what $1,000 buys now.
What Is This Tool?
Inflation slowly erodes what your money can buy. This calculator shows how much money you'd need in the future to match today's purchasing power, based on a steady inflation rate.
Why Inflation Matters
At 3% annual inflation (roughly the US historical average), prices double every 24 years. That means a $50,000 salary in 2000 has the same buying power as about $85,000 today. Wages that don't keep up with inflation make you gradually poorer, even if the number stays the same.
The Rule of 70
A quick mental shortcut: divide 70 by the inflation rate to find the doubling time. At 3.5% inflation, prices double in 70 ÷ 3.5 = 20 years. At 7%, they double in 10 years.
Investing to Beat Inflation
Keeping money in cash means losing ~3% per year to inflation. To preserve purchasing power, you need investments that return more than inflation. The stock market has historically returned ~10% (~7% after inflation), making it a primary inflation hedge for long-term savings.
Frequently Asked Questions
What is a normal inflation rate?
Central banks target ~2% as "healthy" inflation. The US averaged 3% over the last century. High inflation (10%+) or deflation (negative) both cause economic problems.
