Rental deposit calculator (huurwaarborg)
Work out the deposit amount for a residential lease, and see the forms it can legally take in Belgium.
Belgium
The three legal forms a deposit can take
- An individual blocked bank account in the tenant's name — interest accrues to the tenant.
- A bank guarantee, which the tenant can pay off in instalments over up to 3 years.
- A guarantee arranged through the local OCMW/CPAS for tenants who can't provide the amount upfront.
This calculator is informational only, not legal advice, and covers only the standard residential-lease maximum. It doesn't cover shared/student housing or other special regimes — always check your specific lease and region.
Settle deposits with evidence, not memory
Record the deposit on the lease, then document the property room by room with photos at move-in and move-out — so what you hand back is backed by a report both sides have seen.
