它是如何运作的
- Future cost = amount × (1 + inflation)^years.
- Future buying power = amount ÷ (1 + inflation)^years.
- Many central banks, including the ECB and the Federal Reserve, target 2% inflation.
- Savings must earn more than inflation to grow in real terms.
Worked example: 1,000 at 3% for 10 years
- 11.03^10 ≈ 1.344.
- 2Future cost: 1,000 × 1.344 = 1,344.
- 3Buying power: 1,000 ÷ 1.344 = 744.
Prices rise 34% — 1,000 buys what 744 does today
Buying power of 1,000 after 10 years
