What is Inflation?
Inflation is the general and sustained increase in prices of goods and services in an economy over time. In Spain, it is measured mainly through the CPI (Consumer Price Index). When there is inflation, every euro you have buys fewer products than before; that is, you lose purchasing power.
Understanding the Impact of Inflation on your Savings
Imagine you keep €10,000 in a safe today. With an average inflation of 3% per year:
- Today: You can buy a small car for €10,000.
- In 10 years: That same car will cost approximately €13,439.
- The problem: You still only have €10,000 in the safe. Your money 'exists', but it is worth much less.
How to update your rent with CPI?
If your rental contract specifies that the rent will be updated according to the CPI, the landlord can increase the price annually. To calculate it, the interannual rate published by the NSI the month prior to the contract anniversary is taken. It is essential to check if there is a legal maximum cap (such as the 3% limit in Spain during 2024-2025).
Accumulated Inflation: The Reverse 'Compound Interest' Effect
Inflation is cumulative. A 2% annual inflation for 10 years does not mean that prices have risen by 20%, but that they have risen by more than 21.8% due to the compound effect. This is why leaving money idle for decades is financially dangerous.
Comparison: Savings vs Investment vs Inflation

| Savings Account | 1% - 2% | -1% a -2% (Slight Loss) |
| Index Investment (S&P500) | 7% - 10% | +4% a +7% (Real Gain) |
