UAE debt burden ratio (DBR) calculator: how much can you borrow?
Your debt burden ratio is the share of your gross monthly income that goes to debt repayments. The CBUAE caps it at 50% for residents (source: CBUAE). So on AED 30,000 income with AED 3,000 of existing debt, you have AED 12,000/month left for a mortgage, which supports roughly AED 2.35M of borrowing at 3.70% over 25 years. Banks also count 5% of your credit card limits as debt. The calculator below shows your DBR and your maximum mortgage.
UAE DBR and borrowing calculator
Calculator applies the CBUAE DBR method: maximum monthly mortgage payment = (income x DBR cap) minus existing obligations, where credit card obligations count as 5% of the total limit. Maximum loan is the reverse-amortisation of that payment over 25 years at the rate shown. This is the DBR-constrained limit only; your actual maximum is the lowest of DBR, the property loan-to-value cap, and the bank's income multiple.

What is the debt burden ratio?
The debt burden ratio (DBR) is the single most important number a UAE bank checks when deciding how much to lend you. It is the percentage of your gross monthly income that goes to servicing all your debts, including the new mortgage payment. The CBUAE caps it at 50% for residents (source: CBUAE mortgage regulations), which means your total monthly debt payments, with the mortgage added, cannot exceed half your income.
The logic is straightforward: the regulator wants to make sure you can still cover living costs and absorb a rate rise after the mortgage payment goes out. If half your income is already committed to debt, there is no room for a mortgage, however much the property is worth. This is why two people on the same salary can qualify for very different loan amounts. The one with a car loan and high credit card limits has less DBR headroom.
How to calculate your DBR
The formula has two uses. To check your current position, add up all monthly debt payments and divide by gross monthly income:
DBR = (total monthly debt payments including mortgage) / gross monthly income x 100
To find your borrowing limit, work backwards. Multiply your income by the DBR cap, then subtract what you already pay on existing debts. The result is the maximum monthly mortgage payment you can take on:
Max monthly mortgage = (income x DBR cap) minus existing monthly obligations
On AED 30,000 income with a 50% cap and AED 3,000 of existing obligations, that is (30,000 x 0.50) minus 3,000 = AED 12,000 per month available for a mortgage. Run that AED 12,000 through the reverse-amortisation formula at 3.70% over 25 years and it supports about AED 2.35M of borrowing. The calculator above does this for you.
What counts as a debt obligation?
Banks include every recurring credit commitment in the DBR calculation. The ones that catch people out are the credit cards.
| Obligation | How it's counted | Example |
|---|---|---|
| Personal loan | Full monthly instalment | AED 2,000/month loan = AED 2,000 |
| Car loan | Full monthly instalment | AED 1,800/month lease = AED 1,800 |
| Credit cards | 5% of the total limit, even if paid in full | AED 50,000 limit = AED 2,500 |
| Existing mortgage | Full monthly payment | Counts in full for a second property |
| Personal guarantees | May be assessed case by case | Varies by bank |

The credit card rule is the big one. Banks count 5% of your total credit card limit as a monthly obligation, regardless of whether you carry a balance. Pay your cards off in full every month and owe nothing? It does not matter for DBR. A AED 100,000 combined limit across your cards still counts as AED 5,000 of monthly obligations, which can wipe out a large chunk of your borrowing capacity.
The fastest way to increase your borrowing: cut unused credit card limits. If you have AED 100,000 in card limits you don't use, asking the banks to reduce them to AED 20,000 removes AED 4,000 of monthly obligations. On a 50% DBR at 3.70% over 25 years, that frees up roughly AED 780,000 of additional borrowing capacity. Do this a couple of months before applying so it reflects in your credit profile.
Maximum mortgage by income
Here is the DBR-constrained maximum mortgage by income level for an expat resident on the 50% cap, with no existing debts, at 3.70% over 25 years. This is the ceiling before the property loan-to-value limit is applied.
| Gross monthly income | Max monthly payment (50%) | Max mortgage (3.70%, 25yr) |
|---|---|---|
| AED 15,000 | AED 7,500 | AED 1,466,523 |
| AED 20,000 | AED 10,000 | AED 1,955,364 |
| AED 25,000 | AED 12,500 | AED 2,444,205 |
| AED 30,000 | AED 15,000 | AED 2,933,046 |
| AED 40,000 | AED 20,000 | AED 3,910,728 |
| AED 50,000 | AED 25,000 | AED 4,888,410 |
| AED 75,000 | AED 37,500 | AED 7,332,615 |
| AED 100,000 | AED 50,000 | AED 9,776,819 |

These are generous-looking numbers because they assume zero existing debt. In reality, most applicants carry some. Each AED 1,000 of existing monthly obligation cuts roughly AED 195,000 off the maximum loan at these terms. The next section shows that effect.
How existing debt cuts your borrowing
This table holds income fixed at AED 30,000 (expat, 50% cap) and shows how existing monthly debt payments shrink the mortgage you qualify for.
| Existing monthly debt | DBR used by it | Left for mortgage | Max mortgage |
|---|---|---|---|
| AED 0 | 0% | AED 15,000 | AED 2,933,046 |
| AED 2,000 | 6.7% | AED 13,000 | AED 2,541,973 |
| AED 5,000 | 16.7% | AED 10,000 | AED 1,955,364 |
| AED 8,000 | 26.7% | AED 7,000 | AED 1,368,755 |

A car loan and a couple of credit cards can easily total AED 5,000 of monthly obligations, which on this income halves the mortgage from AED 2.93M to AED 1.96M. If you're planning to buy, the single most effective move is clearing or reducing existing debt before you apply. Settling a car loan early can be worth far more in borrowing power than the interest you save on it.
DBR is only one of three caps
The DBR sets your borrowing ceiling from the income side. But your actual maximum loan is the lowest of three separate caps:
- DBR cap: based on income and existing debts, as calculated above.
- Loan-to-value cap: the CBUAE limits how much of the property price you can borrow. An expat borrows up to 80% on a first home under AED 5M, so you need at least a 20% deposit (source: CBUAE). For lower deposits, the LTV cap binds first.
- Income multiple: some banks separately cap the loan at a multiple of annual income, regardless of DBR.
For a buyer with a healthy deposit and modest existing debts, the DBR is usually the binding constraint on higher-priced homes. For a buyer stretching to the minimum deposit, the LTV cap often bites first. Our eligibility wizard checks all three at once and tells you which one limits you. For the deposit side, see the down payment and LTV guide, and for the full borrowing picture read how much mortgage can I get in the UAE.
Frequently asked questions
What is the debt burden ratio (DBR) in the UAE?
It is the percentage of your gross monthly income that goes to all debt repayments, including the new mortgage. The CBUAE caps it at 50% for residents (source: CBUAE). On AED 30,000 income, your total monthly debt, mortgage included, cannot exceed AED 15,000. Banks count existing loans in full and 5% of your total credit card limits.
How do I calculate my debt burden ratio?
DBR = (total monthly debt payments including the new mortgage) / gross monthly income x 100. For your borrowing limit, multiply income by the DBR cap (50% for most residents) and subtract existing obligations. On AED 30,000 income with AED 3,000 of existing debt: (30,000 x 0.50) minus 3,000 = AED 12,000 available for a mortgage.
How do credit cards affect my mortgage DBR in the UAE?
Banks count 5% of your total credit card limit as a monthly obligation, even if you pay in full and owe nothing. A AED 50,000 limit adds AED 2,500 to your obligations. This is a common reason borrowing comes in lower than expected. Reducing unused card limits before applying can noticeably raise the mortgage you qualify for.
What is the maximum mortgage I can get on my salary in the UAE?
With no existing debts on the 50% cap at 3.70% over 25 years: AED 20,000 income supports about AED 1.95M, AED 30,000 about AED 2.93M, AED 50,000 about AED 4.89M. Your real limit is the lowest of three caps: DBR, loan-to-value, and the bank's income multiple. DBR usually binds for higher-priced purchases.
Is the DBR cap different for UAE nationals?
The CBUAE ceiling is 50%, applied to most expat residents. Some banks extend up to around 60% to UAE nationals and certain salary-transfer or government customers, raising borrowing capacity. Non-residents are usually assessed nearer 45%. The exact cap depends on the bank and profile. The calculator lets you set the cap to match your situation.
