What is the Consumer Price Index (CPI)?
In many real estate lease agreements, a clause related to the Consumer Price Index (CPI) is included. The Consumer Price Index (CPI) is an indicator that shows how the prices of goods and services purchased by households change over time. In other words, CPI reflects the level of inflation in a country. It is regularly published by the State Data Agency. Inflation leads to a decrease in purchasing power—over time, the same amount of money can buy fewer goods or services. To ensure that rental income maintains its real value, lease agreements often include rent indexation based on CPI.
How is CPI applied in lease agreements?
Lease agreements typically state that the rent may be adjusted by the landlord once per calendar year, based on the officially published average annual CPI of the Republic of Lithuania for the previous year, as announced by the State Data Agency (usually comparing December to December). For example, if the rent specified in the agreement is EUR 1,000 and the CPI increases by 5% over the year, the new rent will be EUR 1,050 (1000 × (1 + 0.05) = 1050). In such cases, the rent adjustment is usually implemented through a unilateral notice from the landlord to the tenant and comes into effect from January 1 of the current year. This adjustment does not require any amendments to the lease agreement. The new rent amount becomes binding on both parties from the moment the tenant receives the landlord’s notice.
CPI as a practical tool for adapting to economic changes
Applying CPI in lease agreements is a rational and fair way to adapt to economic changes. Such indexation helps maintain a balance between the landlord’s interests and the tenant’s capabilities, ensures long-term financial stability, and promotes transparency in lease relationships. In this way, the landlord protects their income from the effects of inflation, while the tenant can be assured that rent increases only in line with the general price level in the country. This provides a clear and transparent pricing adjustment mechanism and protects against arbitrary or unjustified rent increases.
