How to use this home affordability calculator
- 1Annual gross income and existing monthly debt payments: the inputs lenders use for your debt-to-income ratio.
- 2Down payment available and mortgage rate/term: the loan terms you expect to use.
- 3Maximum debt-to-income ratio: Indian lenders typically allow EMIs (including the new home loan) up to 50-60% of net monthly income; a lower number leaves more monthly breathing room.
Understanding your results
Maximum home price is your down payment plus the largest loan you could service without exceeding your target DTI. Maximum monthly mortgage payment is what's left of your DTI budget after your existing debts — the number your future EMI needs to stay under.
The formula
Max payment = (Income ÷ 12 × Max DTI%) − Existing debt · Max loan = solved from that paymentThe calculator first works out your total allowed monthly debt budget (income times your DTI limit), subtracts what you're already paying toward other debts, and treats what's left as the ceiling for your future EMI. It then solves backward — using the standard loan payment formula in reverse — to find the largest loan amount that fits inside that monthly payment at your given rate and term.
A worked example
A ₹12,00,000 annual income (₹1,00,000/month) with ₹5,000 in existing debt payments and a 50% DTI limit allows up to ₹50,000/month toward all debt (₹1,00,000 × 50%). Subtracting the ₹5,000 already committed leaves ₹45,000/month for a new EMI. At 8.5% over 20 years, that supports a loan of roughly ₹51,85,388 — plus a ₹10,00,000 down payment, a maximum home price around ₹61,85,388.
Things to know
This estimate covers principal and interest only — real affordability also factors in property tax and home insurance, which eat into the same DTI budget and lower your real maximum loan slightly. Treat this as a starting ceiling, then verify with a lender who can quote your exact allowed DTI.
Frequently asked questions
Does this include property tax and insurance?+
No — this estimates the maximum principal-and-interest EMI only. Lenders may factor in property tax and insurance when assessing your real DTI, which will lower your actual maximum loan somewhat versus this estimate.
Why do lenders care about DTI instead of just income?+
Two buyers with the same income can have very different ability to take on a home loan if one already has heavy car or personal loan payments — DTI captures your total debt burden, not just your income, which is a better predictor of repayment risk.
Should I borrow the maximum this calculator shows?+
Not necessarily — this is a lender-affordability ceiling, not a personal comfort recommendation. Many buyers are more comfortable at a meaningfully lower EMI that leaves room for savings, emergencies, and other goals.
