Compare the remaining three-year statutory limit with the comparable local rent you enter. This estimate is for residential leases in the Czech Republic where the parties have not agreed otherwise on rent increases.
The calculation compares the remaining part of the three-year 20% limit with the difference between current rent and the comparable local rent you enter. The remaining statutory allowance is based on rent at the beginning of the three-year period and the increases already made, as entered. The calculator shows the lower of those two amounts as the estimated maximum proposal.
It does not check your entries or the evidence for comparable rent. This is an arithmetic estimate based on section 2249 of the Czech Civil Code, not legal advice on a specific tenancy or proposal.
Section 2249 of the Czech Civil Code governs a landlord’s proposal to increase rent for an apartment or house. It applies when the parties have not agreed on rent increases or expressly excluded them. This calculator reflects Czech law; it is not a tool for German tenancy law, commercial premises or short-term accommodation.
Start by checking the lease and any amendments. An inflation indexation clause or another agreed mechanism may set its own method and timing. Selecting the relevant option stops the calculation because the figures alone could otherwise lead to the wrong conclusion. If the contract is unclear, have it reviewed by a qualified professional.
Under the current wording of section 2249, a proposal cannot be made before twelve months have passed during which rent has not been increased. Enter the number of months since the last rent increase—not the date of the last letter or amendment if the rent changed on another date.
The calculator uses the number only as a basic interval check. It does not verify when the proposal reached the tenant, a contractually agreed date or whether another rent change affects the period. If the change history or contract is unclear, do not treat the result as confirmation that a proposal can be served now.
The law limits the proposed increase together with increases made during the preceding three years. It is therefore not enough to enter current rent and simply calculate another twenty per cent. The calculator also asks for the rent at the beginning of the period and the total amount of increases already made. These inputs should reflect the actual history of agreed rent and changes.
Enter the monthly CZK amounts by which rent was increased in the relevant period, not percentages or changes to service advances. If rent was also reduced, the contract regime changed, or several unusual adjustments were made, a simple sum may not describe the legal position accurately enough. In that case, review the full history rather than relying on this estimate.
The second limit is comparable rent customary in the locality. The calculator does not look up this amount and has no rent database. Enter it only if you have evidence that matches the apartment’s condition, furnishings, size and location. One advertised asking price may not, by itself, reliably establish customary rent.
Section 2249(2) refers the details and procedure for establishing comparable customary rent to implementing legislation. Entering an amount here does not prove that the requirement has been met. Under the current statutory wording, the proposal must also document compliance with the relevant conditions. For a disputed or material increase, have the comparison and evidence reviewed independently.
Current section 2249(1) requires a written proposal. It must state the new rent and document compliance with the conditions in that provision; otherwise it is not taken into account. This page calculates an amount only. It does not draft a proposal, verify service or supply the required attachments and evidence.
If the tenant agrees, the increased rent is payable from the third calendar month after the proposal is delivered. If the tenant does not give written consent within two months, the landlord may apply to the court within the following three months for a rent determination. These are procedural deadlines that depend on exact dates and delivery; this calculator does not track them.
The calculator returns the lower of the remaining entered 20% allowance and the gap to the comparable rent entered. If either amount is zero, the model shows no increase. If the comparable rent you enter is not above current rent, a zero result does not say that current rent must be reduced; it only shows no room under the entered upper limit.
The result assumes accurate figures, a complete history of increases and that the statutory procedure applies. It does not assess the contract, supporting evidence, service of a proposal or whether a court could determine a different rent. Before sending a proposal, check the contract, every increase in the previous three years and the evidence for customary rent. Seek legal advice if anything is uncertain.
Based on section 2249 of Act No. 89/2012, current text effective from 1 January 2026. This is not legal advice.
