How Inflation Erodes Purchasing Power

Inflation increases the cost of goods over time, meaning each dollar buys less in the future.

Formula

Future Equivalent = Amount x (1 + Rate)^Years

Purchasing Power = Amount / (1 + Rate)^Years

The purchasing power formula tells you what your current dollars will be worth in real terms.

Exemple Résolu

$1,000 today with 3% annual inflation over 10 years.

  1. Inflation multiplier = (1 + 0.03)^10 = 1.3439
  2. To buy what $1,000 buys today, you will need $1,000 x 1.3439 = $1,343.92
  3. Purchasing power = $1,000 / 1.3439 = $744.09
  4. Value lost = $1,000 - $744.09 = $255.91
