What DTI do most lenders want to see?

Under 43% for most mortgages, and under 36% is considered comfortably healthy. Some loan programs stretch to 50% with strong credit and reserves.

Do I include rent or mortgage in existing debts?

For a new mortgage application, lenders count the future housing payment inside the DTI instead of your current rent. For other loans, include any housing payment you will keep while repaying the new loan.

Does my credit score change the amount?

It does not change the DTI math, but it strongly affects whether you are approved at that amount and what rate you get — and the rate changes how much loan a given payment supports.

How lenders decide how much you can borrow

Before a lender looks at the house, the car or the loan purpose, it looks at one ratio: your debt-to-income ratio (DTI) — all your monthly debt payments divided by your gross monthly income. DTI answers the lender's real question: after your existing obligations, is there actually room in your budget for another payment? This calculator applies the standard back-end DTI method used in mortgage and personal-loan pre-qualification.

The eligibility formula

Max payment = (Income × DTI limit) − Existing debt payments

The maximum loan is then the present value of that monthly payment at the loan's rate and term — the same annuity math behind the Loan Calculator, run in reverse. Two households with identical incomes can qualify for very different amounts: the one with a car loan and card payments already has part of its DTI budget spent.

What DTI limit should you use?

36% — the traditional comfort zone; many lenders and financial advisers treat this as healthy.
43% — the ceiling for most qualified mortgages in the US; the default here.
50% — reached only with strong compensating factors (high credit score, large reserves, big down payment).

Remember that qualifying is not the same as affording. A lender does not see your grocery bill, childcare or savings goals — borrow against your real budget, not the maximum a formula allows.

Three ways to raise your eligibility

Pay down existing debts — every $100 of monthly payment you eliminate frees roughly $100 of new payment room, dollar for dollar. Increase documented income — a raise, a co-borrower, or two years of side income on tax returns. Choose a longer term or lower rate — the same monthly payment supports a larger loan, though at a higher total interest cost.

Worked example

You earn $6,000 a month and already pay $400 toward debts. At a 43% DTI limit, a lender allows $2,580 of total monthly debt payments; subtracting your $400 leaves $2,180 for a new loan. At 7.5% over 20 years, that payment supports a loan of about $270,600. Eliminate the $400 of existing debts first, and the same income qualifies for roughly $320,300 — a $49,700 difference without earning a cent more.

How to use this calculator

Enter your gross monthly income — before tax, as lenders see it.
Add up your existing monthly debt payments: cards (use minimum payments), car loans, student loans, other installments.
Set the DTI limit — 43% is the common lending ceiling; use 36% for a conservative estimate.
Enter the rate and term you expect for the new loan.
Read your estimated maximum loan — then sanity-check it against your real household budget.

DTI is not the whole decision

Lenders also weigh your credit score, employment stability, savings/reserves and — for mortgages — the property's value (loan-to-value). A strong DTI with a weak credit score can still mean a smaller loan or a higher rate. Use this page to plan, the Mortgage Calculator to cost a specific home, and treat any lender's pre-approval letter as the authoritative number.
