Home Loan EMI Calculator

It depends on the trade-off you prefer between monthly cash flow and lifetime interest. A longer tenure lowers the EMI (which can let you afford a larger home or keep more cash free for other goals), but the total interest paid over the life of the loan rises sharply. A shorter tenure raises the EMI but cuts lifetime interest substantially.

The tenure comparison panel on this calculator shows your specific numbers side-by-side for 15, 20, 25 and 30-year tenures using the same loan amount and rate. A common middle path is to take the long tenure for safety and then prepay aggressively whenever cash allows — this gives you both a low contractual EMI and a short effective tenure.

Every rupee of extra principal you pay reduces the outstanding balance, which reduces every future interest charge on that balance — the saving compounds across all remaining months. You have two options when you prepay:

• Reduce tenure — keep the EMI the same, finish the loan earlier. This saves the most interest because you cut off the most expensive late-stage interest months.
• Reduce EMI — keep the original tenure, shrink the monthly outflow. This saves less total interest but frees up cash flow today.

This calculator models the reduce-tenure pattern by default, which is the more aggressive interest-saving choice. For floating-rate retail home loans the RBI prohibits prepayment penalties, so you can prepay without a charge.

A fixed-rate home loan locks the interest rate for the full tenure (or a long fixed period), so the EMI never changes — predictable but offers no relief if rates fall. A floating-rate loan is benchmarked to an external rate (typically the repo rate or an external benchmark like EBLR); when the benchmark moves, the EMI or tenure resets accordingly.

In India, the vast majority of retail home loans are floating-rate. Floating tends to be cheaper on average over a long tenure, but requires tolerance for monthly cash-flow variability. The other key advantage of floating-rate loans is that RBI prohibits prepayment penalties on them — fixed-rate loans can attract a foreclosure charge.

For a self-occupied property, you can claim deductions in two places under the old tax regime:

• Section 24(b) — interest paid on a home loan is deductible up to ₹2 Lakh per financial year.
• Section 80C — principal repayment is deductible up to ₹1.5 Lakh per financial year (shared with other 80C investments like PPF, ELSS, EPF, life insurance premiums).

The new tax regime (FY 2026-27) does not allow these deductions on a self-occupied property. For a let-out property the interest deduction under Section 24(b) is uncapped against the rental income, with the loss against other heads capped at ₹2 Lakh per year.
