How to Calculate DBR (With Worked Examples)

The exact calculation UAE banks run — formula, the 5% card rule, and three worked examples in dirhams.

The formula
DBR = (monthly loan payments + 5% of total credit card limits) ÷ gross monthly income × 100

Three inputs, one division. The skill is in getting the inputs right — here is each one as a bank sees it, followed by worked examples.

Step 1 — Gross monthly income

Use your full documented income before deductions: basic salary plus regular allowances (housing, transport) as shown on your salary certificate. Irregular bonuses and undocumented income don’t count.

Step 2 — Monthly debt payments

Add every EMI: personal loans, car loans, mortgage. If you guarantee someone else’s loan, many banks include it too.

Step 3 — The credit card 5% rule

Total all your credit card limits — every card, used or not — and take 5%. This is the step most people miss, and it’s explained in depth in DBR and credit cards.

Worked examples

Scenario Income EMIs Card limits (5%) DBR
Young professional AED 10,000 AED 1,200 15,000 (750) 19.5% ✓
Family, car + personal loan AED 18,000 AED 6,500 40,000 (2,000) 47.2% — borderline
Over-committed AED 12,000 AED 5,500 30,000 (1,500) 58.3% ✗ over cap

The second scenario is the instructive one: only AED 500/month of headroom remains, so a new AED 800/month car loan would push them past 50% and be declined — but cancelling an unused card with a AED 20,000 limit frees AED 1,000/month instantly.

Frequently asked questions

What is the DBR calculation formula?

DBR = (total monthly debt payments + 5% of total credit card limits) ÷ gross monthly income × 100. A result at or below 50% is within the Central Bank cap.

Is DBR calculated on gross or net salary?

Gross salary — your full documented income before deductions, including regular allowances. Banks verify it from your salary certificate and bank statements.

How do banks calculate DBR for credit cards?

Each card contributes 5% of its limit per month, regardless of the balance. Two cards with AED 15,000 limits each add AED 1,500/month to your obligations.
