Inflation Calculator — Understand Purchasing Power Over Time

The Inflation Calculator helps you understand how money changes value over time. Enter an amount and two years to see what that money is equivalent to after accounting for inflation.

How It Works

The calculator uses the compound inflation formula: Future Value = Present Value × (1 + inflation rate)^years. This shows how much more (or less) money you need to maintain the same purchasing power.

Key Metrics

  • Equivalent Value — What the amount is worth in the target year.
  • Cumulative Inflation — Total price increase over the period.
  • Average Annual Rate — The yearly inflation rate used.

Why It Matters

Understanding inflation is crucial for retirement planning, salary negotiations, investment returns analysis, and comparing historical prices. A salary that seemed high 20 years ago may be below average today.

Frequently Asked Questions

How does inflation affect purchasing power?

Inflation reduces the value of money over time. $100 in 2000 buys less in 2024 because prices have risen. This calculator shows exactly how much equivalent purchasing power you need.

What inflation rate should I use?

The historical average for the US is about 3% per year. You can customize this based on your country or time period.

Can I calculate backwards?

Yes. Set 'From Year' higher than 'To Year' to calculate what a current amount was worth in the past.

Is my data safe?

Yes. All calculations run 100% in your browser. No data is transmitted.
