What is Inflation Calculator?

An inflation calculator shows how the purchasing power of money changes over time due to inflation. It helps you understand the real value of past and future money.

How It Works

Enter an amount and time period. The calculator uses the specified inflation rate to show the equivalent value in different years, accounting for the cumulative effect of inflation.

The Formula

Future Value = Present Value × (1 + r)^n Purchasing Power = 1 / (1 + r)^n

r = Annual inflation rate (decimal), n = Number of years. Future value shows how much money you'll need to maintain the same purchasing power. Purchasing power shows how much today's money will be worth in the future.

Examples

Example: $1,000 from 2020 to 2026

$1,000 at 3.3% inflation over 6 years

$1,000 in 2020 has the same purchasing power as $1,215 in 2026 due to 3.3% annual inflation. Your money lost about 17.7% of its purchasing power over those 6 years.

Frequently Asked Questions

What is inflation and why does it matter?
Inflation is the gradual increase in prices over time. It matters because it erodes your money's purchasing power—$100 today won't buy the same things in 10 years. Understanding inflation is crucial for long-term financial planning.
What is the average inflation rate?
The U.S. historical average inflation rate is about 3.3% per year (since 1913). In recent years, rates have fluctuated from near 0% to over 9%. The Federal Reserve targets 2% as a healthy rate.
How does inflation affect my investments?
Inflation reduces the real return on your investments. If your portfolio returns 8% but inflation is 3%, your real return is only 5%. This is why it's important to invest in assets that outpace inflation, like stocks.
What is the difference between nominal and real returns?
Nominal returns are the raw percentage gain on an investment. Real returns are adjusted for inflation and show your actual increase in purchasing power. Real return ≈ Nominal return − Inflation rate.
