Purchasing Power of Today's Dollar vs Number of Years
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.
Example Calculation
$1,000 today with 3% annual inflation over 10 years.
- 01Inflation multiplier = (1 + 0.03)^10 = 1.3439
- 02To buy what $1,000 buys today, you will need $1,000 x 1.3439 = $1,343.92
- 03Purchasing power = $1,000 / 1.3439 = $744.09
- 04Value lost = $1,000 - $744.09 = $255.91
