Why is almost nothing coming off the principal in the first year?

Because interest is charged on the outstanding balance, and in year one that balance is at its maximum. The instalment is constant but its composition shifts, and the principal share only becomes substantial in the later half of the term.

Should I take the longest tenure available?

Only if the shorter instalment is genuinely necessary. A longer tenure lowers the monthly figure and raises the total cost sharply — compare the two totals here before deciding, because the instalment alone hides the difference.

What costs are not in this calculation?

Stamp duty, registration, legal and valuation fees, the processing charge, and any insurance the lender bundles. They are paid from your own funds on top of the down payment, and together they are rarely trivial.

Does the interest give me a tax deduction?

Under the old regime, interest on a self-occupied property is deductible within a statutory limit and the principal repayment counts towards 80C. The new regime does not allow either for a self-occupied property, which changes the real cost of the loan considerably.

About the Home Loan EMI Calculator

A home loan is agreed against a property price rather than a loan amount, so this starts where the decision does. Set the down payment as a share of the price and the loan falls out of it, along with the instalment, the total interest and the year-by-year split.

The figure worth stopping on is the first-year breakdown, and the tool prints the exact share rather than leaving you to guess at it. On a twenty-year loan at typical rates roughly four-fifths of the first year's instalments is interest, and the share climbs with the tenure — stretch the same loan to thirty years and it passes ninety per cent. People discover this at the end of year one, look at how little the outstanding balance has moved, and conclude something has gone wrong. Nothing has: a reducing-balance loan charges interest on a balance that starts at its largest, and the principal only begins to fall meaningfully in the second half of the term. Seeing it stated before you sign is better than discovering it afterwards.

That front-loading is also the whole case for prepaying early. A rupee paid into the principal in year two removes eighteen years of compounding interest on that rupee; the same rupee in year sixteen removes four. The prepayment tool works out the difference for a specific loan, and the answer is usually large enough to change behaviour.

Tenure deserves the same scrutiny. Stretching a loan from fifteen years to twenty cuts the instalment by a comfortable-looking amount and raises the total interest by far more than the saving. The instalment is what you feel monthly; the total is what the house actually costs.

Registration, stamp duty, legal fees and the processing charge sit outside all of this and are paid from your own funds alongside the down payment.
