Deposit in Germany: what expats need to know about the rental "Kaution"
Moving into a new home in Germany comes with upfront costs, and the rental deposit ("Kaution") is one of the most important. If you understand how it works, you avoid mistakes, reduce stress, and plan your move realistically.
Quick answer
- The Kaution is up to 3 months' cold rent (Kaltmiete)
- It secures the landlord against damages or unpaid costs
- You get it back after moving out if everything is in order
What is the Kaution?
The Kaution is a mandatory security deposit when renting in Germany.
- Paid at the start of your lease
- Covers unpaid rent, damages, and open utility costs
- This is not a fee. You get the money back if there are no issues.
How much is the deposit?
The legal maximum is 3 times the cold rent (Kaltmiete, rent without utilities).
For furnished apartments: usually 1–2 months' rent, often paid in one instalment.
How do you pay it?
You can legally split the deposit into 3 payments.
- First instalment at move-in, remaining payments over the next two months
- Bank transfer or special deposit account (Mietkautionskonto)
- The first payment must be made before you receive the keys
When do you get it back?
After moving out, the landlord checks the apartment and finances.
- If everything is fine, the deposit is refunded
- Typical timeline: several weeks to a few months
- Delays are common due to final utility calculations
Common mistakes to avoid
- Not documenting the apartment condition (photos and protocol)
- Expecting immediate repayment
- Confusing cold rent with total rent
- Not keeping proof of payment
Bottom line
The Kaution in Germany is standard and regulated. Once you know the rules, there are no surprises. Plan for up to three months' rent upfront, use instalments if needed, and document everything properly.
