What Does a Rental Security Deposit Account Cost?
A rental security deposit account is meant to provide security, but depending on the bank, it can be surprisingly expensive. While some institutions manage the account free of charge, others charge fees for opening, administration, or release.
This article shows what costs arise in practice and why digital rental security deposit accounts are often the simpler solution.
Key Facts About Rental Security Deposit Account Costs – At a Glance
- The costs for a rental security deposit account are usually between 0 and 90 euros total, not per year, depending on the bank.
- Typical cost items at traditional banks are opening fees, ongoing account management, pledge declarations, and fees for release or account closure.
- Interest rates play hardly any role in cost considerations, as returns are very low in practice.
- The person who opens the rental security deposit account also bears the incurred costs.
- Digital rental security deposit accounts, like heykaution, completely waive these fees, as opening, management, and release are automated.
- Hidden costs often arise from services such as document issuance, postal processes, or manual corrections.
What Does a Rental Security Deposit Account Cost in Practice?
It's difficult to name a flat rate. At some banks, the account remains completely free, while others charge amounts between 10 and 90 euros (not per year, but in total). This wide range is mainly due to how internal processes are organized. Where forms still travel on paper and releases are manually checked, additional work arises. And additional work leads to fees, even though they were never legally required.
The same items keep appearing:
- one-time fees for account opening
- annual account management fees
- costs for issuing the pledge declaration
- fees for release or account closure after moving out




Digital providers like heykaution completely waive such fees. The entire process is online, legally secure, and free, making it easy to use for both tenants and landlords.
What Types of Costs Arise at Traditional Banks?
When talking with bank advisors, you quickly realize that rental security deposit accounts don't hold a glamorous place in daily business. They create work but generate little profit as a product. It's therefore not surprising that some banks pass on the costs of their internal processes to customers.
These include:
Opening Fees
At many branch banks, they're somewhere between 10 and 50 euros.
Account Management Fees
Some institutions charge annual fees, usually between 5 and 20 euros.
Costs for Pledge or Release
These additional fees are often between 5 and 25 euros.
Service or Administrative Costs
Sometimes fees are charged that you only learn about when they've already been billed: document issuance, postal processes, manual adjustments, etc.
None of these fees are legally required. They reflect the bank's internal processes rather than real added value for the customer.
Do Interest Rates Still Play a Role Today?
In short: hardly. Interest rates on deposit accounts are in ranges that are symbolic at best. The bottom line is that the financial effect is usually so small that it doesn't really interest tenants or landlords. What's more crucial is how uncomplicated the whole thing runs and whether you end up paying more fees than necessary.
Who Bears the Costs – Tenant or Landlord?
The basic rule is: Whoever opens the rental security deposit account also bears the incurred costs.
The party that opens the account also bears the costs.
This sounds trivial but causes misunderstandings in practice time and again. Some landlords expect the tenant to set up the account, others see it the other way around. With digital models, this question disappears because there are simply no costs.


Three Typical Scenarios from Practice
To make the price differences more tangible, here are three typical cases:
Example 1: Bank with Opening Fee
- Opening:
- 25 €
- Pledge declaration:
- 10 €
- Release:
- 0 €
- Total costs:
- 35 €
Example 2: Bank with Ongoing Fees
- Opening:
- 0 €
- Account management:
- 12 € per year
- Release:
- 10 €
- Total costs after three years:
- 46 €
Example 3: heykaution (digital)
- Opening:
- 0 €
- Account management:
- 0 €
- Release:
- 0 €
- Total costs:
- 0 €
These examples show how strongly costs differ between traditional and digital models.

What Costs Are Often Overlooked?
Many people still keep the opening fee in mind. What often gets lost, however, are the peripheral areas: the final release document, for example, which some banks charge separately. Or the time loss from branch visits when documents need to be checked again. Coordination between landlord and tenant can also eat up time. Especially when documents are missing or need to be corrected multiple times.
Digital providers bypass most of these stumbling blocks simply because work processes are automated. No appointments, no paper, no additional costs.
For Whom Is a Rental Security Deposit Account Worthwhile – and in What Form?
At its core, a rental security deposit account fulfills only one task: The deposit should be kept safe and separate from the landlord's assets. For tenants, this means protection; for landlords, clarity. Differences only arise in implementation – and that's where modern providers are far ahead. They waive fees, reduce time investments, and resolve many old frictions.
