The first step to beating inflation is controlling your expenses and maximizing your monthly savings. Kakebo is your tool to achieve it.
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. In this example, with a hypothetical 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 provides for updating the rent according to the CPI, the actual increase depends on the contract signed, the date of each annual review, and the regulation in force at that time — there is no single percentage that applies to every case. Article 18 of Spain's Urban Leases Act (LAU) caps the annual increase at the CPI variation unless the parties have agreed otherwise, and since 2025 Law 12/2023 on the right to housing replaces that cap, for the contracts it applies to, with the Housing Rental Reference Index that the INE calculates every month. To update your rent with the exact figure for your contract, use the INE's official rent update tool. This page does not provide legal advice: if you have doubts about your contract, check the regulation in force or consult a professional.
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
| Strategy | Typical Return | Real Result (example with 3% inflation) |
|---|---|---|
| Under the mattress | 0% | -3% annual (Loss) |
| Savings Account | 1% - 2% | -1% a -2% (Slight Loss) |
| Index Investment (S&P500) | 7% - 10% | +4% a +7% (Real Gain) |

Methodology and limitations of this calculator
This tool calculates a mathematical projection, not a guaranteed forecast or an official INE figure:
- You enter the inflation rate manually; the calculator does not query any real-time INE data.
- It applies the reverse compound interest formula: Real Value = Savings ÷ (1 + rate)^years.
- It does not yet use official historical CPI series or calculate the real variation between two specific dates.
- The result is indicative only. For the official current inflation or CPI figure, check the INE's CPI portal.
Limitations
- Real inflation varies over time and does not necessarily follow a constant rate like the one used in this calculation.
- The CPI is a national statistical average; your personal inflation may differ depending on your spending habits.
- The calculation does not include taxes, fees, or the real return of any financial product.
- This calculator does not constitute financial or legal advice.
Frequently Asked Questions about CPI in Spain
What is the difference between CPI and Inflation?
Although used interchangeably, inflation is the economic phenomenon (price increase), while the CPI is the statistical tool used by the INE to measure it. The CPI is based on a representative 'shopping basket' (food, energy, transport) of Spanish families.
How to calculate accumulated CPI between two years?
The official formula to calculate the CPI variation is:
Tasa Variación = ((IPC Final - IPC Inicial) / IPC Inicial) x 100This is the formula the INE uses to update rental income for full-year contracts and salary reviews in agreements. You can apply it directly with the INE's rent update tool or by checking the official CPI variation between dates.
How much is my money from 2000 worth today in Spain?
Accumulated inflation in Spain since the year 2000 is substantial, although the exact figure varies depending on the reference month. To find out how much you would need today to match the purchasing power of an amount from 2000, check the INE's official CPI variation simulator.
