Mortgage Points Calculator

Buying a lower rate with points

Mortgage points — also called discount points — let you pay a fee upfront in exchange for a lower interest rate on your home loan. The convention is simple: each point costs 1% of the loan amount and reduces your rate by about 0.25%. On a ₹64 lakh loan, one point costs ₹64,000 and might drop your rate from 8.5% to 8.25%. The question this calculator answers is whether that trade — cash now for a lower EMI later — actually pays off.

The logic mirrors any upfront-cost decision. The lower rate gives you a monthly saving on every EMI for the life of the loan. Divide the point cost by that monthly saving and you get the breakeven — the month at which the savings have fully recovered the upfront fee. Stay in the loan past that point and the points are pure gain; exit before it and they cost you money.

The breakeven decides everything

Whether points make sense comes down entirely to how long you keep the loan. If your breakeven is, say, 40 months and you hold the loan for 15 years, you enjoy years of savings after recovering the cost. But if you plan to sell the property or prepay aggressively within a couple of years, you may exit before breakeven — in which case you paid for a rate reduction you never fully used.

This is why points suit long-horizon borrowers on large, long-tenure loans, where there are many months to accumulate savings and each 0.25% rate cut removes a meaningful amount of interest. On short tenures, the breakeven often lands near the end of the loan, leaving little benefit.

Points in the Indian context

The formal points system is more common abroad, but the same mechanism exists in India in a different guise. Lenders frequently offer a lower rate for a higher processing fee, or a choice between fee structures — which is economically identical to buying points. Whenever you’re offered "pay more upfront for a lower rate," this calculator’s breakeven logic tells you whether to take it.

Points versus a bigger down payment

If you have spare cash, points aren’t the only option. A larger down payment reduces the loan and its interest directly and lowers your risk, while points reduce the rate. For a long-held loan, points can save more; for simplicity and safety, a bigger down payment is often the better default. And remember that in India the loan interest is deductible under Section 24(b) in the old regime, but the upfront point fee generally is not, so treat points as a straight cost-versus-saving calculation.

The bottom line: buy points only when you’re confident you’ll keep the loan comfortably past the breakeven. Test a few scenarios here, weigh them against a larger down payment, and let the breakeven month make the decision for you.
