Inflationsrechner — Formel

Inflation Formula

Future Cost = Current Amount × (1 + r)^n

Where r = annual inflation rate and n = number of years. Inflation erodes purchasing power over time.

Lösungsbeispiel

$100 with 3% annual inflation over 10 years.

  1. Future cost = $100 × (1.03)^10
  2. = $100 × 1.3439 = $134.39
  3. Today's $100 will only buy $74.41 worth of goods in 10 years
  4. Cumulative inflation = 34.4%
