What is DTI and why it matters
Debt-to-income ratio (DTI) is the percentage of your gross monthly income that goes to debt payments. It's the single most important metric lenders use (along with credit score) to decide whether to approve a loan and what interest rate to offer.
A lower DTI means you have more room in your budget to take on new debt — or to save, invest, or handle emergencies.
Front-end vs back-end DTI
- Front-end DTI (housing ratio): only your mortgage/rent divided by income. Lenders want this under 28-32%.
- Back-end DTI: all debts (housing + loans + cards) divided by income. Most lenders require this under 43%, with 36% preferred.
How to lower your DTI
- Pay off credit cards — high-interest debt with high minimums disproportionately raises DTI.
- Refinance existing loans to longer terms (lower monthly payment, even if total interest rises).
- Avoid new debt until you apply for the one that matters (e.g., home loan).
- Increase income — side gigs, salary negotiation, or a spouse's income if applying jointly.
FAQ
What DTI do I need to get a home loan in India?
Most Indian banks allow total EMIs (including the new home loan) up to 50-55% of your net take-home pay. For a clean approval, aim for under 40% back-end DTI.
Should I use gross or net income?
Lenders typically use gross (pre-tax) income for DTI. This calculator also uses gross for consistency. For your own budgeting, back-end DTI calculated on net income is more realistic.
Does rent count as debt?
Yes, in the back-end DTI calculation. Lenders want to see your full housing obligation, whether rent or mortgage.
