Debt-to-Income (DTI) Calculator Saudi Arabia
Whether you are applying for a mortgage, refinancing an auto loan, or trying to secure a personal line of credit, banks don’t just look at your credit score. They look closely at your Debt-to-Income (DTI) ratio.
Your DTI is a percentage that tells lenders how much of your monthly income is eaten up by debt payments. If the number is too high, it signals that you are a high-risk borrower who might default if financial trouble strikes. Use our free Debt-to-Income Calculator to see exactly how banks view your financial health before you apply for your next loan.

How to Calculate Your DTI Ratio
The math behind your Debt-to-Income ratio is simple. Lenders calculate it using this standard formula:
Find your Gross Monthly Income: This is your total income before taxes, health insurance, and 401(k) contributions are taken out. If you earn a $60,000 annual salary, your gross monthly income is $5,000.
Add up your Monthly Debt Payments: Include your rent or mortgage, minimum credit card payments, student loans, and auto loans. Do not include living expenses like groceries, utility bills, or cell phone bills.
Divide and Multiply: Divide the total debt by your gross income, then multiply by 100 to get your percentage.
What is a “Good” DTI Ratio? (The 36 / 43 Rule)
In the United States lending industry, there are two magic numbers you need to know: 36% and 43%.
Below 36% (Excellent/Good): This is the ideal target. A DTI of 36% or less means you have a healthy balance of income and debt. You will likely qualify for the best interest rates available.
36% to 43% (Fair/Acceptable): This is the standard range for most borrowers. Lenders consider 43% to be the absolute maximum DTI ratio you can have and still qualify for a “Qualified Mortgage” (like an FHA or Conventional loan).
44% to 50% (Warning): You are stretching your budget thin. Some lenders may approve you up to a 50% DTI, but they will require “compensating factors,” such as a massive down payment, substantial cash reserves, or an 800+ credit score.
Above 50% (Critical): Borrowing options will be extremely limited. Lenders will view you as too high-risk for new credit.
Front-End DTI vs. Back-End DTI
If you are buying a house, your mortgage broker might use two different DTI calculations:
Front-End Ratio (Housing Ratio): This only looks at your housing expenses (mortgage principal, interest, taxes, and insurance) divided by your gross income. Lenders typically want this number to be 28% or lower.
Back-End Ratio (Total Debt Ratio): This is what our calculator above measures. It includes your housing expenses plus all other recurring monthly debts. Lenders strictly cap this at 36% to 43%.
How to Lower Your DTI Quickly
If your DTI is too high to get approved for a mortgage, you only have two options: decrease your debt or increase your income.
Attack Credit Card Balances: Because credit cards have high minimum payments relative to their balances, paying off a $2,000 credit card can eliminate a $100/month payment, instantly lowering your DTI.
Avoid Taking on New Debt: Do not finance a new car or open new credit lines in the months leading up to a mortgage application.
Increase Gross Income: Consider picking up a side hustle or asking for a raise. Lenders will factor in additional income as long as you have a documented history (usually two years of tax returns) to prove it is consistent.
