Paying points means handing over cash upfront to reduce the rate. One point is typically 1% of the loan. The question is always: how long to recoup that cash in lower payments. A 3,000 point cost that saves 40/month breaks even at 75 months — 6.25 years. If you plan to stay 10 years and not refinance, points win. If you might move at year 5, they lose.

Quick example

With upfront points cost of 3,000 and monthly payment saving of 40 (plus remaining mortgage months of 300), the result is 75 months. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.

Which inputs matter most

You enter Upfront Points Cost, Monthly Payment Saving, and Remaining Mortgage Months. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

What's happening under the hood

Break-even month = upfront cost divided by monthly saving. Ignores time value of money — strict payback period. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.

What the headline rate hides

Lenders quote a rate; what you pay is a blend of that rate, fees, insurance, and any early-repayment penalty built into the product. The figure here isolates the core interest cost so you can compare like-for-like across deals — then add the other costs separately before signing anything.

What this doesn't capture

The figure excludes arrangement fees, valuation costs, legal fees, insurance, and any early-repayment charges — those can add several thousand to the headline cost. Rate changes at renewal for fixed-term deals will shift the picture further. Use this for the core interest/principal math and add the other costs on top.

Example Scenario

Frequently Asked Questions

Are points always worth it?
Only if you stay past break-even. Shorter horizons lose the upfront cash. The longer you hold the loan, the more points pay off.
Is there a tax angle?
In some jurisdictions mortgage points are deductible. Tax rules change over time — verify current treatment with an accountant before relying on a tax benefit.
Does refinancing reset the clock?
Yes. If you refinance before hitting break-even, you lose the unrecouped cash. Any plans to refinance should push you toward no-point loans.
Are points negotiable?
Sometimes. Lenders may bundle points as part of a quote. Always ask for a no-points version alongside any points offer.
