Debt burden ratio
Most people meet DBR as a number quoted at them (50%) with no explanation. Here is what it actually measures, what it counts, and why reaching the limit is not the same as being offered it.
Short answer
DBR stands for debt burden ratio. It is the share of your monthly income that goes towards paying debts.
In the UAE the ceiling is 50%. That does not mean a bank will lend you up to 50%. Banks are told not to apply the maximum automatically.
It compares what you have to repay each month against what you reliably earn. If your debt payments come to half your income, your DBR is 50%.
The ceiling is 50% of gross salary and any regular income from a defined and specific source. That is the regulator’s wording, and each part of it does something. Gross means your pay before deductions, not what lands in your account. Regular means it keeps coming, not one-off. And a defined and specific source means the bank can point to where it comes from.
Say you earn AED 30,000 a month.
The 50% ceiling means all your monthly debt payments together should come to no more than AED 15,000.
If you already pay AED 4,000 towards a car loan, that leaves AED 11,000 of room for a mortgage payment, before the bank applies its own, usually tighter, view.
This is an illustration, not a promise of what a bank will lend you. Your own figures and your own bank will differ.
If what you really want to know is whether you can borrow and roughly how much, what UAE banks look at answers that directly.
More than most people expect. The 50% limit applies to everything you owe banks and finance companies together, not to each one separately.
Not just the bank you are applying to. A loan or card at another bank counts exactly the same.
Named in the regulation. These are usually the second largest item after a mortgage.
Housing loans are named too. If you already own, this is normally your biggest item.
The facility counts, not the balance you happen to be using today.
Named in the regulation. This is the one that surprises people: a card you never use is still a card you hold.
Your new payment is added to the rest. You are tested on where you would be after buying, not where you are now.
The regulation names car loans, housing loans, overdrafts and credit cards without limiting the list to those. A safe assumption: if a bank or finance company can take money from you each month, it is in the calculation.
Because the regulation says so, in as many words. When banks assess whether you can afford to repay, they are told not to automatically apply the maximum debt burden ratio, and to take account of your particular circumstances.
So a bank that stops well short of 50% for you is not being awkward. It is doing what it has been told to do. Two people with the same DBR can get different answers, and the same person can get different answers from two banks, without either being wrong.
Your DBR is not worked out on the payment you would actually start making. Banks have to test you at 2 to 4 percentage points above the current rate. If your rate is an introductory one, they test you at the rate that applies once it ends.
This matters more than it sounds. A low starting rate does not buy you room, because it is not the rate you are assessed at.
Your mortgage runs past retirement. The bank has to be satisfied you could still afford what is left at 50% of your income after you retire. Since that income is usually lower, this often shortens the term you can have rather than the amount.
You are buying to rent out. At least two months of rental income must be taken out of the calculation, to allow for months when the property sits empty. The rent counts, just not all of it.
DBR is one of three limits. You are held to whichever is lowest.
| What is being tested | What it limits |
|---|---|
| Your income (DBR) | How much of your income can go towards debt |
| The property | How much of the property’s value you can borrow |
| A multiple of your annual income | Your total borrowing |
How the property limit works covers the second one. And because the limits interact, clearing a credit card can move your position further than another good month of income would. The calculator shows which one is actually holding you back.
The 50% ceiling does not change. What gets harder is proving the income half of it. If you earn through a business, how banks read business income decides what goes into the calculation at all. If you live outside the UAE, what changes for a non-resident buyer is mostly about which banks will look at your file.
List every loan, card and overdraft you hold, at every bank, including the ones you never use. Work out your income as gross and regular, not as what arrives in your account. Then find out which of the three limits actually applies to you, because that is the one worth doing something about.
