How to use this debt-to-income (dti) calculator
- 1Gross monthly income: your income before tax — the same figure lenders use.
- 2Total monthly debt payments: add up every minimum payment — home loan or rent, car loans, education loans, credit cards, personal loans. Don't include everyday expenses like groceries or utilities; DTI is about debt specifically.
Understanding your results
Your DTI ratio is the single number most lenders check first. Under 36% is generally considered healthy, 36-43% is workable but tighter, and above 43% starts to shut doors with many traditional lenders — though limits vary by loan type and lender. Income after debt payments shows what's left for everything else: housing costs (if not already included), savings, and daily spending.
The formula
DTI = (Total monthly debt payments ÷ Gross monthly income) × 100The calculation is a straight percentage — no compounding, no time dependency. Lenders typically split this into a 'front-end' ratio (housing costs only) and a 'back-end' ratio (all debt, including housing) — this calculator computes the back-end ratio, the one most often used as the headline qualifying number.
A worked example
A ₹80,000 gross monthly income with ₹23,000 in total monthly debt payments (rent, car loan, one credit card) gives a DTI of about 29% — comfortably inside the 'healthy' range most lenders look for, leaving ₹57,000 a month for everything else.
Things to know
DTI thresholds vary by loan type and lender — home loan providers, personal-loan lenders and NBFCs each set their own limits and compensating factors, so treat the 36%/43% guideline above as a general planning benchmark rather than a fixed rule any single lender follows. A low DTI also matters beyond loan approval — it's a genuine signal of how much breathing room you actually have each month.
Frequently asked questions
Does DTI include my rent or home loan EMI?+
Yes — housing costs (rent, or home loan EMI covering principal and interest) count as a debt payment in the standard 'back-end' DTI calculation this calculator uses.
What's a 'good' DTI ratio?+
Below 36% is generally seen as healthy by most lenders. 36-43% is still workable for many loan types but leaves less room to qualify for the best rates. Above 43% starts to limit options with many traditional lenders, though this varies by loan program.
Does a high DTI hurt my credit score?+
No — DTI isn't a factor in your credit score (such as your CIBIL score) itself, but it directly affects whether lenders will approve you for new credit and at what rate, independent of your score.
