Ask anyone what their home costs and you will get the EMI. It is a clean, memorable monthly figure, and it is incomplete in three separate ways.

First, it excludes everything paid before you moved in — the down payment, the stamp duty and registration, and the interiors. On a ₹1 crore home with a 20% down payment in urban Karnataka, that is roughly ₹20 lakh plus ₹6.6 lakh plus whatever the fit out costs, all of it gone before the first EMI is debited.

Second, it excludes what you pay every month alongside it. Association maintenance is a real, permanent, rising bill, and on an amenity-heavy project it can run to a meaningful fraction of the EMI. Property tax is annual and small by comparison but it never stops. Neither appears on any brochure.

Third, it tells you nothing about what the money is buying. A large share of every early EMI is interest, and interest is the one line in a home purchase that leaves you with nothing. Seeing that number stated separately is uncomfortable and useful in equal measure.

One nuance worth understanding before you read the monthly average: it depends on how long you own the home. Spread the down payment and registration over five years and the average sits far above the EMI; spread the same money over twenty-five and the gap narrows sharply, and once the loan is fully repaid the average drops below the EMI entirely. Move the ownership slider and watch it — the shape of that curve is itself an argument for buying to hold.

This calculator earns its keep when two shortlisted homes carry the same headline price. Run each one and the differences show up immediately.

A project with a heavy amenity programme carries a higher per-square-foot maintenance charge, and over ten years that gap compounds into several lakh. A larger super built-up area at the same price means the same maintenance rate applies to more square feet. A ready-to-move home has no GST but usually a higher headline price; an under-construction one has GST and a possession date you are betting on. A home that needs full interiors starts several lakh behind one that comes with them.

None of these differences are visible in a price. All of them are visible in a ten-year total. That is the comparison worth making before you shortlist, not after.

Every assumption is a slider on this page, including maintenance inflation and the interest rate, and none of them is a forecast. Registration cost is computed from Karnataka stamp duty rates as last reviewed on 2026-08-01; those rates are set by the state, change with state budgets, and must be verified before you transact.

Left out deliberately: repairs and replacements, which are genuinely unpredictable and vary with build quality; home insurance; any tax deduction you may be able to claim on home-loan principal or interest, which depends on your tax regime and personal circumstances and is not something a generic calculator should assume for you; and GST, which you should add into the price if you are buying under construction. Rental income, if you plan to let the property, is also not modelled.

What this page does not do is tell you the home is a bad idea because the total is large. Every home has a large total. The point is to see it before you commit, not in year three. If the deeper question is whether to buy at all, run rent vs buy, which tracks what you get back as well as what you put in. If the question is what you can carry, the affordability calculator is the place to start.
