How it works
Cost of points = loan × points × 1%. New rate = current rate − (points × reduction per point). We then amortize the same loan at the new rate to find the new monthly P&I, and divide the upfront cost by the monthly savings to get the break-even month.
Frequently asked questions
What is a mortgage discount point?
A fee paid at closing to permanently lower your interest rate. One point equals 1% of the loan amount and typically buys a 0.25% rate reduction.
Are points worth it?
Only if you'll keep the mortgage past the break-even month. Sell or refinance earlier and you lose money on the points.
Are points tax-deductible?
On a primary residence purchase, points are generally deductible the year you pay them. On a refinance, you must amortize them over the loan term.
Can I negotiate the cost per point?
Yes — the 0.25% reduction is typical but varies by lender and market. Always shop quotes with the same points scenario.
Should I buy points or put more down?
Extra down payment reduces the loan and PMI; points only reduce the rate. Compare both break-evens before deciding.
