Calculate rent reduction in the event of mould, noise or heating failure
The heating breaks down in winter. Mould is spreading in the kitchen. The house has been under construction for months and there is no peace and quiet.
Situations like this are stressful for tenants. Many then ask themselves the same question: Can I reduce the rent - and if so, how much?
Our rent reduction calculator will give you a realistic initial estimate. Quick, free and without registration.
When can the rent be reduced?
A rent reduction can be considered if there is a significant defect that noticeably restricts the use of the flat. This includes, among other things:
- Mould infestation
- Heating failure
- No hot water
- Moisture or water damage
- Strong and permanent construction noise
- Defective windows
- Lift failure on higher floors
It is important that the defect was not caused by the landlord and that the landlord was informed about it. The landlord can only react once he has been informed.
The rent reduction is generally automatic if there is a significant defect. Nevertheless, you should not act too hastily. An excessive reduction can lead to payment arrears and, in the worst case, result in cancellation.
How does the rent reduction calculator work?
Our calculator is based on published case law on rent reduction. In many cases, courts have decided which reduction rates are appropriate for certain defects.
You enter:
- What type of defect is present
- How long the defect exists
- How high your monthly rent is
- The extent to which use is restricted
You will then receive a percentage estimate and the possible reduction amount in euros.
The result serves as a guide. Each case has special features that may play a role in the event of a dispute.
Why a calculation makes sense
Many tenants underestimate how high a rent reduction can be. Others reduce too much or too little out of uncertainty.
A comprehensible calculation provides security.
You know the scope of your claim.
You can speak objectively with the landlord.
And you avoid unnecessary risks.
Especially if a defect persists for several months, a rent reduction can add up significantly.
What you should look out for before cutting back
Before you reduce the rent, you should document the defect. Photos, records and witnesses can be important later.
Inform the landlord in writing and set a reasonable deadline for rectification. Keep all documents.
Legal advice can be useful for larger amounts or complicated situations. This will help you avoid mistakes that can be costly.
