How the loan eligibility calculator works

Lenders cap your total debt payments at a share of your income — your debt-to-income (DTI) ratio. The calculator takes your income times the DTI limit to find the maximum total debt payment you can carry, subtracts your existing debt payments, and what remains is the biggest new monthly payment you can afford. It then works backwards through the loan formula to find the largest loan that payment supports.

Max total payments = Income × DTI limit
Available for new loan = Max total − Existing debts
Max loan = Payment × (1 − (1 + r)^−n) / r,  r = rate/12

This is an estimate of borrowing capacity, not a guarantee — lenders also weigh credit score, employment, and down payment. Once you know a target amount, use our Loan / EMI Calculator to plan the repayment, or the Mortgage Calculator for a home.

Understanding debt-to-income limits

The classic guideline is the 28/36 rule: no more than 28% of gross income on housing, and no more than 36% on all debt combined. Many mortgage programs allow a back-end DTI up to 43%, and some go higher with strong credit. A lower DTI not only qualifies you for more — it also leaves you more breathing room if your income dips or rates rise.

  • Lower your DTI: paying down existing debts frees up room for a larger new loan.
  • Longer terms raise eligibility: they lower the monthly payment, but cost more interest overall.
  • Gross vs net: lenders use gross (pre-tax) income, so your real take-home budget is tighter than the limit suggests.

Frequently asked questions

What is a debt-to-income ratio? +
DTI is the share of your gross monthly income that goes to debt payments. Lenders use it to judge whether you can afford a new loan. A lower DTI signals more capacity to borrow and a lower risk of default.
What DTI do lenders usually require? +
Many conventional loans prefer a total DTI at or below 36%, though some mortgage programs allow up to 43% or more with compensating factors like strong credit or a large down payment. Auto and personal lenders vary.
Does this guarantee I’ll be approved? +
No — it estimates capacity based on income and DTI only. Actual approval also depends on your credit score, employment history, down payment, and the lender’s specific rules. Treat the result as a planning ceiling, not a promise.
Should I borrow the maximum I’m eligible for? +
Usually not. The maximum stretches your budget to the lender’s limit. Borrowing below your ceiling leaves a cushion for emergencies, rate changes, or income dips, and keeps your finances more resilient.
What counts as existing debt? +
Minimum monthly payments on car loans, student loans, credit cards, and other installment debts. Rent, utilities, groceries, and taxes are generally not counted in DTI, though lenders consider your overall budget.
This calculator is an educational estimate, not a lending decision. Actual eligibility depends on your full credit and financial profile and each lender’s criteria. Confirm with a lender before relying on these figures.
