Calculation of the Price-Income Index & the Multiplier Index - Without Dynamics





With a purchase price of 500,000 € and an annual net income of 20,000 €, the price-income index is 25.00.
The multiplier index is 41.67.
So you would need 25.00 years of net income to cover the purchase price, or 41.67 years of cold rent to cover the purchase price.

ℹ️
What do these indices tell me?
The empirica AG publishes a quarterly Immobilien Blasenindex (Q1 2025) for Germany's major cities.
Here you can compare the indices and protect yourself from overpaying.
