Frequently asked questions

What DTI ratio do I need for a mortgage?

Conventional mortgages typically require a back-end DTI of 36% or below, though some lenders approve up to 43%. FHA loans allow up to 43% standard and up to 50% with strong compensating factors (high credit score, large reserves). VA loans technically have no DTI cap but most lenders want 41% or below.

What is the difference between front-end and back-end DTI?

Front-end (or housing) DTI is only your housing costs divided by gross income. Back-end (total) DTI includes all recurring debts: housing, car, student loans, credit cards, and other obligations. Lenders look at both, but the back-end ratio is usually the binding constraint. The standard limits are 28% front-end and 36% back-end.

Does DTI use gross or net income?

DTI always uses gross monthly income (before taxes and deductions). This is the standard across all lender calculations. Your take-home pay is lower, so a 36% DTI based on gross income may actually consume 45–50% of your net pay. Keep this in mind for personal budgeting.

Which debts count in the DTI calculation?

Any recurring monthly obligation that appears on your credit report: mortgage/rent, auto loans, student loans, credit card minimums, personal loans, alimony, child support, and co-signed debts. Utilities, insurance (unless escrowed), subscriptions, and food do not count. If you can see it on your credit report, it counts.

How can I lower my DTI quickly?

Pay off small debts entirely (removing a payment), increase your income (side job, raise), avoid taking on new debt, and pay down credit cards below their minimums. Paying off a $200/month car loan improves DTI more than paying an extra $200 toward a $1,800 mortgage. Target the smallest balances first for fastest ratio improvement.

Is a 20% DTI better than 35% for my finances?

Lower is better for borrowing capacity and financial resilience, but extremely low (under 15%) might mean you are under-leveraged and missing investment opportunities. A DTI of 20–28% gives you good borrowing capacity while maintaining cash flow for savings and emergencies. Above 36% becomes risky if income drops.
