How this calculation works
Divide the sum of the scheduled monthly debt payments by gross income for the same month. The remaining gross amount is shown separately, before taxes, household spending and savings.
DTI = monthly debt payments ÷ gross monthly income × 100%A worked example
₹15,000 of monthly debt payments divided by ₹50,000 gross monthly income gives a 30% ratio.
Good to know
This is a descriptive ratio, not an Indian or foreign lender eligibility rule. Definitions and thresholds vary. Remaining gross income is not disposable income. Irregular income needs a reasonable comparable monthly figure.

Use payments in the numerator
An outstanding loan balance is a stock of debt, while a monthly repayment is a flow of money. For this ratio, enter the scheduled monthly payments. Dividing a ₹5,00,000 loan balance by monthly salary answers a different question.
Keep the two inputs on the same time basis. If an income figure is annual, convert it to a reasonable monthly amount before entering it. A bonus or seasonal income needs a treatment that matches the purpose of your comparison.
Gross income is before taxes and deductions. A ratio calculated with take-home pay can be useful for another budgeting exercise, but it is not the gross-income DTI defined on this page.
A ratio is a summary rather than a complete budget
With ₹50,000 gross monthly income and ₹15,000 listed debt payments, the ratio is 30%. The remaining ₹35,000 is still gross income: taxes, food, transport, housing costs not included in the debt figure and savings can all compete for it.
Two households with the same ratio can have different financial pressures. Fixed living costs, dependants, irregular earnings and emergency reserves do not appear in the division. Use the ratio alongside a fuller monthly budget.
No color band here labels a result as approved, safe or rejected. Lenders can define obligations differently and apply different rules by product and jurisdiction. A generic ratio should not silently turn a foreign rule of thumb into an Indian eligibility standard.
A few questions, answered
Can the ratio be more than 100%?
Yes. If scheduled payments exceed gross income, the arithmetic ratio exceeds 100%. The tool shows that outcome rather than hiding it behind an arbitrary maximum.
What if I have no debt payments?
With positive gross income, zero entered debt payments gives a zero ratio. It does not mean there are no household expenses.
Should rent be included?
Use a consistent definition for your purpose. Some assessments include housing obligations and others distinguish them. The calculator divides your chosen total and does not determine a lender’s required definition.
