Quick answer: how to calculate DTI

DTI = total monthly debt payments ÷ gross monthly income. ₹40,000 of debt payments on ₹1,00,000 income is a 40% DTI — near the limit many lenders accept.

Overview of the Debt-to-Income (DTI) Ratio Calculator

Your debt-to-income (DTI) ratio shows how much of your income goes to debt. Lenders use it to judge whether you can afford a new loan — in India a similar measure is called FOIR (fixed obligations to income ratio). Enter your gross monthly income and your monthly debt payments to see both the front-end (housing) and back-end (all debts) ratios.

A lower DTI means more borrowing room. Most lenders prefer a back-end ratio of 36% or less and rarely go above 43–50%. Use the House Affordability Calculator to turn your DTI into a loan size, or the Debt Payoff Calculator to bring it down.

How We Calculate

The calculator applies the standard financial formulas step by step.

  1. Add up your monthly debt payments: housing, vehicle, personal and education loans, and card minimums.
  2. Divide the total by your gross monthly income and multiply by 100 for the back-end DTI.
  3. Divide only the housing payment by income for the front-end ratio.
  4. Compare with typical limits: about 28% front-end and 36% back-end are common guides, with 43–50% as an upper limit.
back-end DTI = total monthly debt payments ÷ gross monthly income × 100
front-end = housing payment ÷ gross monthly income × 100
