Dubai mortgage calculator: how much can you borrow?
Sarah ChohaibAuthorPublished 3 August 2026 · Last updated 23 August 2026
Your Dubai mortgage calculator result is really two numbers: the loan your income supports under the 50% debt burden ratio cap, and the loan your deposit supports under the 80% loan-to-value cap for an expat resident's first property under AED 5M. At an indicative 3.89% over 25 years, every AED 1,000 of monthly instalment supports roughly AED 191,600 of borrowing.
The formula behind every mortgage calculator UAE result
Every UAE bank's monthly mortgage payment calculator, and ours, runs on the same amortisation formula: instalment = P × r × (1+r)^n ÷ ((1+r)^n − 1), where P is the loan amount, r is the interest rate divided by 12, and n is the number of monthly instalments over the term. Put plainly: the bank works out what fixed monthly payment, held steady for the full term, exactly clears the loan plus interest by the last instalment.
Nothing about that formula is bank-specific. What differs between lenders is the rate charged, the term offered and, critically, the rate used to test whether you can afford the loan in the first place. Many banks stress-test at two to three percentage points above the offered rate, so the amount a bank actually approves is often lower than a simple online calculator suggests.
| Rate | 15 years | 20 years | 25 years |
|---|---|---|---|
| 3.89% | AED 7,342 | AED 6,002 | AED 5,218 |
| 4.09% | AED 7,442 | AED 6,107 | AED 5,328 |
| 4.29% | AED 7,543 | AED 6,214 | AED 5,440 |
Read the table as a scaling factor. Borrowing AED 2M at 4.09% over 20 years is simply the AED 1M figure doubled: AED 12,214 a month. The shorter the term, the higher the monthly payment but the lower the total interest paid, because the balance is repaid faster and interest accrues on a shrinking principal every month.
| Rate | 15 years | 20 years | 25 years |
|---|---|---|---|
| 3.89% | AED 321,538 | AED 440,479 | AED 565,346 |
| 4.09% | AED 339,571 | AED 465,760 | AED 598,457 |
| 4.29% | AED 357,748 | AED 491,288 | AED 631,941 |
The 50% debt burden ratio, applied to real income
The UAE Central Bank caps total monthly debt service, including the new mortgage instalment, life and property insurance, at 50% of monthly gross income. Every existing obligation counts against that ceiling: car finance, personal loans, school fee instalment plans, and roughly 5% of every credit card limit whether or not you carry a balance on it.
| Monthly income | Existing debt | Payment capacity | Max loan |
|---|---|---|---|
| AED 15,000 | AED 0 | AED 7,500 | AED 1,437,000 |
| AED 25,000 | AED 2,000 | AED 10,500 | AED 2,012,000 |
| AED 40,000 | AED 4,000 | AED 16,000 | AED 3,066,000 |
| AED 60,000 | AED 5,000 | AED 25,000 | AED 4,791,000 |
Each max loan is the payment capacity divided by the AED 5,218-per-AED-1M factor from the 25-year table above, then multiplied by AED 1M. That is the entire calculation a mortgage calculator UAE tool runs behind the scenes for the income side of the sum — the deposit side is a separate, second ceiling.
Then the loan-to-value ceiling caps the other side
Even a high earner cannot borrow past their loan-to-value limit. The Central Bank sets LTV by buyer type and price band, and your maximum loan is whichever of the DBR result and the LTV result is lower.
- First property under AED 5M, UAE resident: 80% LTV, so a minimum 20% deposit.
- First property over AED 5M: 70% LTV, minimum 30% deposit.
- Second or investment property: 60% LTV.
- Non-resident buyers: typically 50–60% LTV, bank-dependent.
- UAE nationals: generally 5 points higher LTV than the expat tiers above.
Worked example: putting both ceilings together
Take a buyer earning AED 25,000 a month with an AED 2,000 car loan, eyeing a AED 2.2M apartment with a 20% deposit ready. DBR capacity is 50% × 25,000 = AED 12,500, minus the AED 2,000 car loan, leaving AED 10,500 a month. At 3.89% over 25 years that supports roughly AED 2,012,000 of borrowing. The 80% LTV ceiling on a AED 2.2M property caps the loan at AED 1,760,000. Here the LTV limit binds first: the buyer is approved for AED 1,760,000, comfortably inside their DBR capacity, and needs the AED 440,000 balance plus transaction fees in cash.
| Property price | 20% deposit | 4% DLD fee | 2% agency fee | Admin (approx.) | Total cash needed |
|---|---|---|---|---|---|
| AED 1,000,000 | AED 200,000 | AED 40,000 | AED 20,000 | AED 4,200 | AED 264,200 |
| AED 1,500,000 | AED 300,000 | AED 60,000 | AED 30,000 | AED 4,200 | AED 394,200 |
| AED 2,000,000 | AED 400,000 | AED 80,000 | AED 40,000 | AED 4,200 | AED 524,200 |
| AED 3,000,000 | AED 600,000 | AED 120,000 | AED 60,000 | AED 4,200 | AED 784,200 |
| AED 5,000,000 | AED 1,000,000 | AED 200,000 | AED 100,000 | AED 4,200 | AED 1,304,200 |
Where simple online calculators mislead buyers
- 1They ignore the stress-test rate, so they overstate what a bank will actually approve.
- 2They omit mandatory life and property insurance, commonly AED 150–500 a month, which counts inside the 50% DBR ceiling.
- 3They assume an introductory fixed rate runs the full term, when it typically reverts to a margin over EIBOR after year one, two or three.
- 4They rarely show both the DBR ceiling and the LTV ceiling side by side, so buyers see only the more flattering of the two numbers.
- 5They skip the transaction costs entirely, leaving buyers short of cash at the final Dubai Land Department appointment.
How term length changes your borrowing power
Extending the term lowers the monthly instalment for the same loan, which raises how much a fixed income can support. Moving from 20 years to 25 years at 3.89% lowers the per-AED-1M payment from AED 6,002 to AED 5,218, a roughly 13% reduction, which lifts DBR-based borrowing capacity by a similar margin. The trade-off is total interest: the same AED 2M loan costs about AED 881,000 in interest over 20 years versus AED 1,130,700 over 25 years, a difference of roughly AED 250,000 for the extra five years.
What a calculator cannot tell you
A calculator gives you a ceiling, not an offer. Banks weigh employer category, credit history through Al Etihad Credit Bureau, probation status, and whether income is salaried or self-employed differently, and two banks can approve materially different amounts for an identical income and price. Lenddoo runs the same file across 18+ UAE banks at no cost to the borrower, so the number you act on is a real approval rather than a formula's estimate.
Salary-to-loan table across common income bands
Combining the DBR and LTV logic above into one reference table makes it easier to sanity-check a target property against your own income before running the full mortgage calculator. All figures assume no existing debt and the 3.89% / 25-year factor used throughout this article.
| Monthly salary | Max loan (50% DBR) | Max property price (80% LTV) |
|---|---|---|
| AED 12,000 | AED 1,150,000 | AED 1,437,000 |
| AED 18,000 | AED 1,724,000 | AED 2,155,000 |
| AED 22,000 | AED 2,108,000 | AED 2,635,000 |
| AED 35,000 | AED 3,353,000 | AED 4,191,000 |
Worked example at a lower price point
Not every buyer is looking at a multi-million dirham property. Take a AED 950,000 apartment with a 20% deposit (AED 190,000) and a buyer earning AED 14,000 a month with no existing debt. DBR capacity is AED 7,000 a month, supporting roughly AED 1,341,000 at 3.89% over 25 years — comfortably above the AED 760,000 loan needed here, meaning the LTV ceiling, not income, is the binding constraint on this purchase. Total cash needed, including the roughly 6.5% in closing costs, comes to about AED 251,750.
Common mistakes when using an online mortgage calculator
- Trusting a single online estimate as a guaranteed approval. It is a starting reference point, not an offer — always confirm with a formal pre-approval.
- Leaving out insurance premiums, which count toward the 50% DBR cap and can shave a meaningful amount off your true borrowing capacity.
- Ignoring the difference between the offered rate and the bank's stress-test rate, which is usually the real reason an approval comes in lower than expected.
- Not checking affordability from both sides — cross-check your result against the affordability calculator as well as the LTV table above.
