Why these calculators exist
Most disagreements between Dubai landlords and tenants are not really disagreements about fairness. They are disagreements about arithmetic, and about which rule applies. Dubai rental law is unusually specific: there is a fixed ceiling on the security deposit, a five-tier formula governing how much rent may rise at renewal, a published Ejari fee, and a conventional way of splitting rent into post-dated cheques. When both parties can see the number the law produces, the argument tends to end.
What each tool answers
The rent increase calculator applies Decree No. 43 of 2013. You enter what you currently pay and what comparable units in the area let for, and it returns the maximum increase your landlord may lawfully request, from zero up to twenty per cent depending on how far below market your rent sits.
The security deposit calculator applies the statutory caps: five per cent of annual rent for an unfurnished property, ten per cent where it is furnished. It is most useful before signing, when a landlord has named a figure and you want to know whether it is within the law.
The Ejari fee calculator sets out the AED 220 registration cost alongside the other charges that arrive at the start of a tenancy — agency commission, DEWA and cooling deposits, move-in permits — so the true cost of taking a property is visible before you commit.
The cheque schedule calculator turns an annual rent and a chosen number of cheques into the actual dates and amounts you will write, which is the detail that belongs in Section 5 of the contract and the one most often recorded inconsistently.
All four are free, require no account, and store nothing. They are guides based on published Dubai regulations; for the official figure in a formal dispute, the Dubai Land Department's own index in the Dubai REST app is authoritative.
