What is Inflation Calculator?

Measures the compounding decline in currency purchasing power caused by ongoing monetary inflation over a multi-year horizon.

How to Use This Calculator

  1. Enter initial purchasing amount.
  2. Set expected annual inflation rate.
  3. Choose time horizon in years.
  4. Review future required dollars and cumulative purchasing power loss.

The Mathematical Formula & Variables

Future Cost = P * (1 + inflation)^years

Step-by-Step Worked Example

Scenario: $1,000 baseline with 2.5% annual inflation over 20 years.

  1. (1 + 0.025)^20 = 1.638616.
  2. 1,000 * 1.638616 = $1,638.62 needed in 20 years.

Result: $1,638.62

Frequently Asked Questions

What is the Rule of 72 for inflation?

Divide 72 by the annual inflation rate to find roughly how many years until price levels double (e.g. 72 / 3% = 24 years).
