Quick answer: how much house can I afford?

On a ₹18,00,000 income with ₹10,000 of monthly debts and ₹10,00,000 down at 8.5% for 20 years, you can afford a home of about ₹58,39,695.27 (monthly housing cost ₹42,000.00).

Overview of the House Affordability Calculator

Lenders limit how much of your income can go to housing and to all debts together. This calculator applies two common limits — housing at 28% of gross income and total debts at 36% — takes the smaller housing payment that fits both, and converts it into a loan size and home price using your rate, term, property tax and insurance.

You can edit both ratios to match a lender's rules. Reduce other debts to raise your budget. Then check the details with the Mortgage Calculator, see your ratio with the DTI Calculator and plan your savings with the Down Payment Calculator.

How We Calculate

The calculator applies the standard financial formulas step by step.

  1. Monthly income = annual income ÷ 12.
  2. Housing limit = income × housing ratio (28%). Total-debt limit = income × total ratio (36%) − your existing debts. Use the smaller figure.
  3. Convert the payment into a price: price = (housing payment − insurance + down payment × k) ÷ (k + property tax rate), where k is the EMI per rupee borrowed.
  4. Loan = price − down payment; show EMI, tax and insurance to check the total.
price = (H − insurance + down × k) ÷ (k + tax rate)
k = r ÷ (1 − (1 + r)^−n), H = min(income × 28%, income × 36% − debts)

House Affordability Calculator — Frequently Asked Questions

How much house can I afford?

Many lenders cap housing costs at about 28% of gross income and total debt at about 36%. This calculator uses those limits, which you can edit.

What is the 28/36 rule?

A guideline that housing costs should be at most 28% of gross income and all debt payments at most 36%.

Does my down payment raise what I can afford?

Yes — it reduces the loan, so more of the price fits into the same monthly payment.

Do existing debts matter?

Yes. They use up part of the 36% limit, leaving less for housing.

What else should I budget for?

Registration and stamp duty, maintenance, moving and an emergency fund — beyond the monthly payment.

Is this the amount a bank will lend?

Not necessarily. Banks also check credit score, age, job stability and the property's valuation.

How is the house affordability calculator calculated?

It uses the standard formula: price = (H − insurance + down × k) ÷ (k + tax rate) The full method and a worked example are shown on this page.

Is this financial advice?

No. The calculator gives estimates for planning and learning. Real offers vary by lender, product and date, so confirm the details with your bank, lender or a qualified adviser before deciding.

Can I use another currency?

Yes. The maths is identical in any currency; only the currency symbol shown in the results differs.

Is my data stored?

No. Everything is calculated in your browser and nothing you enter is uploaded or saved.
