The single line that can sink a mortgage approval
Before a UAE bank looks at your deposit or the property, it runs one test that quietly decides most applications: the debt burden ratio. The Central Bank of the UAE rule, as modelled by this calculator, caps your total monthly debt repayments at 50 percent of your monthly income. If everything you owe each month, taken together, exceeds half what you earn, the lender cannot approve the new borrowing, full stop. It is a hard ceiling, not a guideline the bank can flex for a good customer. The calculator divides your combined repayments by your income and tells you whether you sit inside the cap and how much monthly headroom you have left. The 50 percent figure is the rate this tool applies, and you should confirm the current cap with the Central Bank of the UAE, as the regulation is reviewed from time to time.
Everything counts, including debts you have forgotten
The ratio is unforgiving about what goes into the numerator. It is not just the new mortgage. It includes your car loan, any personal loans, the repayment on other property, and a notional slice of your credit card limits, commonly 5 percent of the total limit even if you clear the card in full every month. That last point trips people up constantly: a credit card with a high limit you never use still eats into your borrowing capacity, because the bank assumes you could draw it down. School-fee loans and buy-now-pay-later commitments can count too. The income side is usually your stable, documented salary, sometimes with a haircut on variable bonus or rental income. Before you apply, it is often worth closing an unused card or paying down a small loan, because shrinking the numerator can be what tips a borderline case into approval.
A AED 40,000 income comfortably inside the cap
Take someone earning AED 40,000 a month, taking on an AED 8,000 mortgage repayment, with AED 4,000 of other monthly debt. Their total repayments are AED 12,000, which is 30 percent of income, well below the 50 percent ceiling.
| Step | Amount |
|---|
The cap at half of AED 40,000 is AED 20,000, so with AED 12,000 committed there is AED 8,000 of monthly headroom, room to take on more borrowing or absorb a rate rise. The chart shows the ratio against the ceiling, with the unused headroom shaded.
When you breach the cap, and what to do
If your repayments climb to half your income or beyond, the calculator flags that you are over the ceiling and the headroom turns into a shortfall. There is no point applying in that state, because the bank simply will not lend. The levers are limited but real: extend the mortgage term to lower the monthly repayment, though the term cannot exceed the maximum and your age at maturity caps it too; clear or consolidate other debts to free up the ratio; or buy a less expensive property so the mortgage repayment is smaller. A larger deposit also helps indirectly, since a smaller loan means a smaller repayment. The debt burden ratio works alongside the loan-to-value cap, so a deposit that clears the LTV rule is wasted if the repayment fails this test. This tool is for anyone gauging borrowing capacity before applying, and for existing borrowers checking whether a new loan or car finance would push them over the line.
Does my credit card count even if I pay it off every month?
Yes, and this surprises a lot of applicants. Banks typically count around 5 percent of your total card limit as a monthly commitment regardless of whether you carry a balance, because the limit is credit you could draw at any time. A pile of high-limit cards you never use can therefore quietly cut your mortgage capacity, which is why closing spare cards before applying often helps.
Is the cap really fixed at 50 percent for everyone?
The 50 percent figure is the standard Central Bank ceiling this tool models, and banks apply it consistently. Some lenders are stricter internally, or treat variable income like bonuses and commission cautiously, so your effective limit can be tighter than the headline. Confirm the current rule and how your specific income is assessed with the Central Bank of the UAE and your chosen lender.
