Purchasing Power Loss -- What It Means for Your Money
Purchasing power loss is every saver's silent enemy. While your account balance stays the same, the real value of your money continuously declines. At 3% inflation per year, EUR 10,000 loses nearly 26% of its purchasing power in just 10 years -- EUR 10,000 becomes only EUR 7,441 in real terms. After 25 years, more than half is gone.
The Formula Behind Purchasing Power Loss
The calculation is simple but powerful: Real Value = Nominal Value / (1 + Inflation Rate)^Years. For EUR 1,000 at 3% inflation over 20 years: 1,000 / (1.03)^20 = EUR 553.68. This means your EUR 1,000 can only buy goods in 20 years that would cost EUR 553.68 today.
Purchasing Power Loss by Time Period (at 3% Inflation)
- 5 years: -14% (EUR 1,000 becomes EUR 863)
- 10 years: -26% (EUR 1,000 becomes EUR 744)
- 15 years: -36% (EUR 1,000 becomes EUR 642)
- 20 years: -45% (EUR 1,000 becomes EUR 554)
- 25 years: -52% (EUR 1,000 becomes EUR 478)
- 30 years: -59% (EUR 1,000 becomes EUR 412)
How to Avoid Purchasing Power Loss
The only way to avoid purchasing power loss is to earn a return above the inflation rate. Historically, broadly diversified equity ETFs (e.g., MSCI World) have achieved an average return of 7-8% per year -- well above the long-term inflation rate of 2-3%.
