Comprehensive Calculator Guide
Last updated: August 2026
Your debt burden ratio is the share of your monthly salary already committed to instalments. Lenders in Saudi Arabia treat it as the first gate on any financing application: before they look at your income or your employer, they check how much of that income is already spoken for. This calculator shows your current ratio, how much financing capacity is left, and whether an expected instalment would push you past the allowed cap.
How the ratio is calculated
The formula is simple: total monthly instalments divided by net monthly salary, times 100. Net salary means what actually reaches your account after social insurance deductions, not the gross figure in your contract. Using gross is the most common mistake and it always produces a ratio lower than the real one.
Instalments include every fixed monthly commitment: personal finance, real estate finance, car instalments and credit card payments. Some lenders also count a percentage of your card limit even when the balance is zero, which is why an applicant's own calculation sometimes comes out lower than the bank's.
Why the caps differ
The Saudi Central Bank sets responsible-lending principles that cap the deduction ratio to protect borrowers from debt they cannot carry. The caps vary by financing type and borrower status: consumer finance has one ceiling, real estate finance is allowed a higher one because it is secured against an asset, and retirees face a lower ceiling because a pension is fixed and cannot grow.
These are regulatory maximums, not a promise of approval. Every lender applies its own policy on top, often more conservative, and may decline an application that sits inside the legal limit for reasons of credit history or length of service.
That is why the cap field here stays editable. Regulations are revised, and a hard-coded number in any calculator quietly goes stale. Adjust it to whatever your lender tells you.
Worked examples
An employee with a net salary of SAR 12,000 and a car instalment of SAR 1,800 has a current ratio of 15%. At a 33.33% consumer cap, the maximum allowed commitment is SAR 4,000, leaving SAR 2,200 a month available for a new instalment.
An employee earning SAR 9,000 with SAR 2,500 of personal finance and a SAR 400 card payment is committed to SAR 2,900, a ratio of 32.2% and effectively at the ceiling. Any new financing would breach it, so the only route is to settle or reschedule an existing obligation first.
A retiree on a SAR 8,000 pension with no obligations is capped at 25%, allowing SAR 2,000 a month. That is roughly what an employee earning SAR 6,000 could take on, despite the pension being a third higher.
Raising your capacity before you apply
The fastest route is reducing the numerator rather than growing the denominator. Clearing your smallest obligation lifts your capacity immediately, usually by more than waiting for an annual raise would. Closing an unused credit card can free room too, where the lender counts its limit.
Extending the financing term lowers the monthly instalment and therefore the ratio, but raises the total you pay. That is a genuine trade, not a trick: you are buying today's approval with more money over time. Run it through the loan calculator before deciding.
Finally, check your credit record before applying. A settled obligation that has not been updated still reads as active to the lender, and your ratio is calculated higher than it truly is.
How to Use
- 01Enter your net monthly salary as it reaches your account, after social insurance.
- 02Enter the total of your current monthly instalments, including credit cards.
- 03Enter the expected new instalment, or leave it at zero to see only your current ratio.
- 04Pick the financing type: consumer, real estate, or retiree. This sets the cap automatically.
- 05Adjust the cap manually if your lender quotes a different figure.
- 06Press calculate to see your projected ratio, the maximum allowed, and what is left.
Formula Used
Debt burden ratio = (total monthly instalments / net monthly salary) x 100Practical Examples
SAR 12,000 salary, SAR 1,800 existing instalment
Current ratio 15%. At a 33.33% cap the maximum commitment is SAR 4,000, leaving SAR 2,200 a month for a new instalment.
SAR 20,000 salary with real estate finance
At a 65% cap the maximum commitment is SAR 13,000. With SAR 3,000 already committed, SAR 10,000 a month remains, which is what sets the ceiling on the property you can buy.
Important Tips
- Use net salary, not gross, or your ratio will look better than it is.
- Clearing your smallest obligation raises capacity faster than waiting for a raise.
- Ask your lender which ratio it actually applies. It may be stricter than the regulatory cap.
- Check your credit record so settled obligations are not still counted against you.
Common Mistakes to Avoid
- Using gross salary instead of net.
- Leaving credit card instalments out of the obligations total.
- Assuming that sitting inside the cap guarantees approval.
- Extending the term to lower the ratio without checking the added total cost.
Frequently Asked Questions
- How is this different from debt-to-income ratio?
- The deduction ratio measures monthly instalments against monthly income. Debt-to-income measures total debt against annual income. Saudi lenders base the financing decision on the first.
- Does an unused credit card count?
- Some lenders count a percentage of the card limit as an obligation even at a zero balance. If you do not use the card, closing it can free financing room.
- Is housing allowance part of the salary figure?
- It depends on the lender. Some count basic salary only, others add fixed allowances. Ask before applying, because the difference is significant.
- Why is the retiree cap lower?
- A pension is fixed, cannot grow, and absorbs financial shocks less well than employment income. The lower ceiling protects the borrower.
- I am over the cap. What are my options?
- Three: reduce the amount requested, extend the term to lower the instalment while accepting a higher total cost, or settle an existing obligation before applying.
- Are the caps in this calculator official?
- They are common guideline figures, not a substitute for what your lender tells you. Regulations are revised and policies differ, which is why the field stays editable.
