Inflation Calculator

Inflation describes the general increase in the price level over a specific period. When inflation rises, you can buy less with the same amount of money – your purchasing power decreases. In Germany, inflation is measured using the Consumer Price Index (CPI), which the Federal Statistical Office publishes monthly. The CPI is based on a basket of around 700 goods and services that represent the typical consumption of a German household.

The CPI is based on a basket that represents the average consumption of private households. Around 700 goods and services are tracked, from groceries to rents to leisure spending. Each item is weighted according to its share of total expenditure. The weighting is regularly updated (most recently 2020 = base year 100). Prices are collected monthly from around 35,000 reporting points.

Purchasing power loss means your money becomes worth less over time. If inflation is 3% per year, for example, you can only buy goods worth about EUR 970 (measured at today's price level) with EUR 1,000 after one year. Over longer periods, this effect accumulates significantly: at 3% inflation, money loses about half its purchasing power in 25 years.

There are several reasons: First, we notice price increases more for products we buy frequently (groceries, fuel) than for products we rarely buy (electronics, which often get cheaper). Second, the CPI basket changes regularly – new products are added, others removed. Third, the CPI captures quality improvements: if a laptop costs EUR 800 today but is twice as powerful as 5 years ago, the quality-adjusted price has fallen even though the nominal price stayed the same.

The statutory pension in Germany is regularly adjusted, but not directly to inflation – instead to wage development. During periods of high inflation, pension adjustments can lag behind price developments. Our pension check shows you how the purchasing power of your pension develops under different inflation scenarios. At 3% inflation and 1.5% pension increases, your pension loses about 25% of its purchasing power in 20 years.

Inflation is a general price increase, deflation a general price decrease. While inflation reduces the purchasing power of money, deflation theoretically increases it. Deflation sounds positive at first, but is economically dangerous: if consumers expect prices to keep falling, they postpone purchases – the economy shrinks, companies lay off workers, a downward spiral can develop. The ECB therefore aims for inflation of just under 2%, which is considered a sign of a healthy economy.

Our calculator uses official Consumer Price Index data from the Federal Statistical Office (Destatis). For years from 1991 onward, we use the all-German index; for earlier years, the West German index. The category multipliers are simplified approximations based on historical averages. For precise analyses of individual product groups, we recommend the GENESIS database from Destatis.

The hyperinflation of 1923 was the most extreme episode: in November 1923, a loaf of bread cost 233 billion marks. In the post-war period (from 1949), the highest annual inflation was just under 8% in 1951. More recently, inflation reached 8.8% in October and November 2022 – the highest since reunification – driven by the energy crisis and pandemic aftereffects. Our calculator covers the period from 1950 onward.

There are several proven strategies: Real assets like real estate and stocks historically offer the best inflation protection. Broadly diversified equity ETFs have significantly outpaced inflation long-term. Inflation-linked bonds adjust their payouts to inflation. Gold is considered traditional inflation protection but provides no ongoing returns. Fixed-rate savings products (savings accounts, fixed deposits) lose real value during high inflation – the return must exceed the inflation rate.

The euro introduction in 2002 led to a widespread perception of price increases, earning the nickname 'Teuro' (expensive euro). Official data shows overall inflation in 2002 was a moderate 1.4%. However, prices in certain sectors (restaurants, services) rose noticeably, as many businesses used the conversion to round up. The official exchange rate was 1 EUR = 1.95583 DM. Use our D-Mark converter to calculate the actual purchasing power development since the changeover.

Not all prices rise at the same rate. Food and housing/energy have historically risen faster than average (multipliers 1.15 and 1.25 respectively). Healthcare and leisure have risen less (0.90 and 0.85). With the category selector, you can see how purchasing power has developed differently across life areas. Example: EUR 1,000 from 2000 for food has a different purchasing power today than EUR 1,000 for leisure spending.

The European Central Bank (ECB) aims for a medium-term inflation rate of 2%. This target is a compromise: too-low inflation (or deflation) inhibits economic growth because consumers and businesses postpone investments. Too-high inflation devalues savings and creates uncertainty. The 2% provides a buffer against deflation and allows room for relative price adjustments between different economic sectors. Since 2021, the ECB has pursued a symmetric 2% target, meaning deviations above and below are evaluated equally.
