UAE Central Bank DBR Rules: How Banks Calculate Your Limit

UAE banks calculate your mortgage limit using the Central Bank’s Debt Burden Ratio (DBR) rule: total monthly commitments (including the new mortgage) cannot exceed 50% of gross monthly income. This guide explains how banks treat income and commitments, how they apply the rule, and how you can improve your eligibility. We reference UAE Central Bank circulars and bank policy.

50% DBR Cap and Exceptions

The 50% DBR cap means your total monthly debt (existing loans, credit card minimums or a percentage of limits, and the new mortgage payment) divided by your gross monthly income must be 50% or below. Some banks use basic salary only; others use basic plus part of allowances. Check with each bank.

Income Components Banks Use

Income components: salary certificates and bank statements are used to verify income. Bonus and other variable income may be discounted or averaged. Self-employed applicants need audited accounts and proof of income. Ensure your paperwork clearly shows your income.

Commitments: Loans, Cards, Rent

Commitments: banks add existing personal loans, car loans, and credit card obligations (minimum payment or a percentage of the limit). They may also add a notional rent if you do not own a home. List all commitments and have statements ready.

How Banks Apply the Rule

How banks apply the rule: they sum your commitments, add the proposed mortgage payment, and divide by income. If the ratio is above 50%, they may reduce the loan amount or decline. Different banks can treat income and commitments slightly differently, so shop around.

Improving Your Eligibility

Improving eligibility: pay down other debt to lower your commitments; add a co-borrower with income; or choose a bank that uses total income (including allowances) if your basic is low. Do not take on new debt before applying. Use our Mortgage Affordability Calculator to see your likely limit.
