Debt-to-Income (DTI) Ratio Calculator

This free online debt-to-income (DTI) ratio calculator helps you determine what percentage of your gross monthly income goes toward paying off debts such as rent, EMIs, and credit card bills. Lenders use this figure to gauge how much additional debt you can safely take on, and this tool gives you an instant assessment alongside the ratio.

How to Use the Debt-to-Income Calculator

  1. Enter your total monthly debt payments (rent, EMIs, credit cards, etc.) in the "Total Monthly Debt Payments (₹)" field.
  2. Enter your gross monthly income before taxes in the "Gross Monthly Income (₹)" field.
  3. Click the "Calculate DTI" button.
  4. Review your "DTI Ratio" and its qualitative "Assessment" in the result box.

How the Assessment Bands Work

The ratio is your monthly debt payments as a percentage of gross monthly income, shown to two decimals. The calculator then places it in one of four bands:

DTI ratioLabel shownWhat it generally means
Below 20%ExcellentPlenty of room for savings and for a new loan
20% to 36%Good / ManageableComfortable for most households
Above 36% up to 43%BorderlineLenders may reduce the loan amount offered
Above 43%HighLittle buffer for emergencies; new credit is harder to get

The 36% and 43% cut-offs come from mortgage lending practice in the United States. They are a reasonable personal benchmark, but Indian lenders apply their own limits, described below.

DTI and FOIR: How Indian Lenders Look at It

Banks and NBFCs in India usually talk about FOIR, the fixed obligations to income ratio. It is the same idea, but it is commonly measured against net take-home income rather than gross, and it counts loan EMIs and card obligations; whether rent is included varies. The acceptable FOIR differs by lender and rises with income, with many lenders working within roughly 40% to 60%.

Because net income is lower than gross, the same EMIs produce a higher FOIR than DTI. To estimate your FOIR, run the calculator a second time with your in-hand salary in the income field.

Worked Example

Gross monthly income is ₹1,00,000 and take-home pay is ₹80,000. Existing obligations are a car loan EMI of ₹12,000, a personal loan EMI of ₹8,000 and ₹3,000 of card dues, a total of ₹23,000. DTI = 23,000 ÷ 1,00,000 = 23.00%, labelled "Good / Manageable". Measured on take-home pay it is 28.75%.

If a lender allowed a 50% FOIR on the ₹80,000 take-home, total EMIs could reach ₹40,000, leaving room for a new EMI of about ₹17,000. At 8.5% over 20 years that EMI supports a home loan of roughly ₹19.6 lakh. Taking a home loan with a ₹25,000 EMI instead would push the DTI to 48%, in the "High" band.

Lowering Your Ratio Before Applying

  • Close small loans that are near their end; removing a ₹5,000 EMI can matter more to eligibility than the outstanding amount suggests.
  • Clear revolving credit card balances, since lenders may count a share of the outstanding as a monthly obligation.
  • Add a co-applicant with their own income, which lenders combine when assessing a home loan.
  • Choose a longer tenure to lower the new EMI, keeping in mind that it raises the total interest paid.

Frequently Asked Questions

The calculator divides your total monthly debt payments by your gross monthly income and multiplies by 100, using the formula DTI = (Monthly Debt ÷ Monthly Income) × 100.

A DTI below 20% is labeled "Excellent", up to 36% is "Good / Manageable", up to 43% is "Borderline" and may affect loan eligibility, and anything above 43% is flagged as "High" since it is likely to affect loan eligibility with most lenders.

You should include all recurring debt obligations such as rent or mortgage payments, EMIs, credit card minimum payments, and other loan installments; do not include everyday expenses like groceries or utilities.

No, the result is a general guideline based on common lending practices; actual loan approval criteria vary by lender, so use this calculator only as an indicative, free planning tool.

The classic DTI ratio uses gross income, and the assessment bands on this page assume that. Many Indian lenders, however, judge affordability against net take-home pay. Running both gives you a fuller picture: the gross figure for the standard ratio, and the net figure for how a bank is likely to see it.
