About this calculator
Debt-to-income ratio (DTI) is the most important number you've never been told about. Banks compute it before approving any loan, fintechs use it to size your credit limit, and financial planners use it to flag households heading for a cash-flow squeeze. It compares everything you owe each month -- home EMI or rent, car loans, education loans, personal loans and credit card minimums -- against your gross monthly income.
There are two flavours of DTI lenders care about. Front-end DTI is housing-only -- ideally below 28% of gross income. This protects you from being house-poor: too much money locked into one shelter cost. Back-end DTI is total debt over income, which most banks cap at 40-50% for home loans. Cross those thresholds and you'll be denied, or offered a worse rate to compensate for higher default risk.
DTI is also a self-discipline tool. Every new EMI permanently lowers the cash you can save or invest. A 50% DTI household is one job loss or medical emergency away from defaulting. A 25% DTI household has space to invest, save and absorb shocks. Track DTI quarterly and treat 35% as a hard ceiling you don't cross unless adding the debt also adds long-term wealth (a home, education, productive business). Pair this calculator with the [[debt-snowball]] calculator to map a payoff plan when you're over the limit, the [[home-loan]] calculator to see how much home you can really afford, and the [[net-worth]] calculator for the bigger balance-sheet picture.

Frequently asked questions
What DTI do banks consider safe for a home loan?
Most Indian banks cap total DTI at 50% of gross income for salaried borrowers, with the EMI alone (front-end) staying below 40%. NBFCs and HFCs sometimes stretch to 55-65% but at higher interest rates and with stricter documentation.
Should I include rent in my DTI?
Yes if you currently rent and the loan you
Does gross or net income matter for DTI?
Banks use gross monthly income (before tax). Internally, you should also track DTI against net income (post-tax take-home) -- a 40% gross DTI can easily be 50%+ of net income, which is the cash you actually live on.
How can I lower my DTI quickly?
Three levers: clear high-EMI loans early using bonus or savings, refinance to longer tenure (lower EMI but more total interest), or grow income via a raise, side income or rental income. Avoid taking new loans even for purchases that
Do credit card balances count even if I pay in full each month?
If you always pay in full and on time, the bank typically uses your minimum due as the DTI charge -- usually 5% of the outstanding balance. If you carry a revolving balance, the EMI-equivalent is higher and you should add 5-10% of the average balance as the DTI line.
