Inflation Rate

Definition

What inflation is, how it is measured (CPI), and why it silently destroys your savings. How to protect your money from inflation in Poland.

Quick Answer

The inflation rate is the percentage change in the general price level of goods and services over a period, usually measured year-over-year, and it quantifies how quickly money loses purchasing power. The most common measure is the Consumer Price Index (CPI), published by national statistical agencies such as GUS in Poland or Eurostat for the EU. Many central banks target around 2% inflation; the National Bank of Poland targets 2.5% with a plus or minus 1 percentage point band. When the inflation rate exceeds the interest on your savings, your real return turns negative.

FAQ

What is the inflation rate?

The inflation rate is the percentage change in the general price level of goods and services over a given period, usually measured year-over-year. It quantifies how quickly money loses purchasing power. The most common measure is the Consumer Price Index (CPI), published by national statistical offices.

How is CPI calculated?

CPI is calculated by tracking the prices of a representative basket of goods and services consumed by households, weighted by category (food, housing, transport, etc.). National statistical agencies, such as GUS in Poland or Eurostat for the EU, collect price data regularly and update the basket weights periodically. The result is a single index that reflects average consumer price changes.

What is a typical central bank inflation target?

Many central banks target a CPI inflation rate around 2%, considered consistent with price stability. The National Bank of Poland targets 2.5% with a plus or minus 1 percentage point tolerance band. Targets vary by jurisdiction and are reviewed periodically.

How does inflation rate affect savings?

A positive inflation rate reduces the purchasing power of money held in low-yield accounts. If the inflation rate exceeds the nominal interest rate on your savings, your real return is negative. This is why long-term financial plans typically include an inflation assumption.

What is the difference between headline and core inflation?

Headline inflation includes all items in the CPI basket, including food and energy, which can be volatile. Core inflation excludes food and energy to reveal underlying price trends that are less subject to short-term shocks. Central banks often watch both measures when making policy decisions.
