Discount points and break-even: what a point buys, and when it loses
Discount points are the clearest trade in a refinance: you hand the lender cash at closing and in return the note rate on the loan is lower for as long as you keep it. The payment saving is real, but it arrives slowly, a month at a time, while the cost arrives in one lump on day one. Whether points help depends on a single comparison: how many months of the lower payment it takes to return the cash, against how many months you will actually stay in this loan. That is break-even math, and it is the same math this site applies to every refinance decision, just with a bigger cost in the numerator.
What a point is, and is not
The Consumer Financial Protection Bureau puts it plainly: one point equals 1 percent of your loan amount. One point on a $100,000 loan is $1,000. One point on a $400,000 loan is $4,000. Points do not have to be round numbers. CFPB notes a quote might carry 1.375 points, 0.5 points, or 0.125 points, and each fraction scales the same way off your balance. Points appear on page 2, Section A of the Loan Estimate and Closing Disclosure, alongside other origination charges.
Two things a point is not. It is not a rate, and it does not buy a fixed, published rate reduction. CFPB is explicit that how much a point lowers your rate depends on the lender, the kind of loan, and market conditions that day. Any rule of thumb you have heard about a set reduction per point is not a promise. The only rate reduction that matters is the one on your own same-day quote, with and without points, from the same lender on the same loan.
The points break-even, in isolation
Isolate the points decision from the refinance decision. First, does the refinance itself pay back its ordinary closing costs before you expect to move or refinance again? Second, and separately, do the points pay back? The points math is: points cost divided by the extra monthly payment saving the points create, compared with the zero-point version of the same loan. The answer is a month count, the same as every break-even on this site.
Work it as a reading exercise. Suppose a quote sheet shows that paying one point costs $4,000 and lowers your monthly payment by $65 compared with the zero-point quote. Divide $4,000 by $65 and the points break even in month 62, rounded up. Stay in the loan past month 62 and the points are ahead. Move, sell, or refinance again before month 62 and the points finish underwater, because the lower rate stops the day the loan ends. The numbers in your quote will differ. The division does not.
Points stack on top of total break-even
A purchased point is a closing cost like any other, so it also belongs in the total picture. If a refinance carries $6,000 of true closing costs and you add one $4,000 point, the loan now has to repay $10,000 before it is ahead. Even when the points eventually pay back on their own clock, they push the whole refinance's break-even later and increase the cash you must bring, or the balance you must borrow if costs are rolled in.
That is why the cleanest test uses the calculator twice. Run your balance, rate, term, and closing costs once at the zero-point rate, and once at the points rate with the point added to closing costs. The break-even guide walks through the base math, and the third-party fees and lender fees guides show which costs count as true closing costs instead of prepaids. Points are always true cost. They never come back at payoff.
When points lose
Points lose most often on time. A household that expects to move in three years, or that has refinanced twice in five years, is buying a lower rate for a loan it is unlikely to keep long enough to collect on. They also lose when the balance is small: one point on a small loan is cheaper in dollars, but the monthly saving shrinks with it, and the month count to repay can stretch just as long. They lose when the rate reduction on offer is thin, when cash at closing is tight, or when the same cash would do more work reducing the balance itself.
There is a quieter losing case. Points are paid once and are easy to forget, so borrowers compare the points rate against rental ads and headlines instead of against their own zero-point quote from the same hour. A points rate can look impressive next to a competitor's zero-point rate while being the worse deal of the two. The comparison that matters never crosses lenders or days.
How to price points before you buy them
Ask for the zero-point quote first, then the same loan with one point, then half a point if it is offered. You are buying a rate reduction, so make the seller state its size and price side by side. By law, CFPB notes, points shown on the disclosure must be connected to a discounted rate. If a Loan Estimate shows points without a rate improvement over the zero-point quote, that is a question to put to the lender in writing before you proceed.
Then divide. Points cost by the monthly saving the points alone create, and compare the month count with an honest stay horizon, not an optimistic one. If the count is comfortably inside the months you are confident you will keep this loan, points can be a reasonable purchase of a lower payment. If the count sits near your horizon, the points are a bet, and you should know you are placing it.
Worked example
Stated example: a $400,000 balance, 27 years left on the current loan, a new 30-year term, and $6,000 of closing costs before points, with a planned stay of seven years in the new loan. One point on this balance costs $4,000 at closing. Suppose the same-day, zero-point quote and the one-point quote differ by $65 a month in payment: the point alone breaks even in month 62, which is inside the 84-month stay, so this household would collect on it. Fold the point into the refinance and total closing costs rise to $10,000, so the whole deal must also be re-tested in the calculator at the lower rate before the point earns its place.
The trap most people miss
The trap is shopping the points rate against everyone else's zero-point rate. The point only has to beat one quote: the zero-point version of your own loan, offered the same day, by the same lender.
Checklist
- Get the zero-point quote and the points quote from the same lender on the same day.
- Confirm the point's dollar cost equals the stated percent of your loan amount.
- Divide the points cost by the monthly saving the points alone create. Note the payback month.
- Add the point to total closing costs and re-run the whole refinance break-even in the calculator.
- Compare the payback month with the stay you are confident about, not the stay you hope for.
Common questions
How much does one point reduce my rate?
There is no fixed amount. CFPB says the reduction depends on the lender, the loan type, and market conditions. The only reliable figure is the difference between your own zero-point and points quotes from the same lender on the same day.
Are points the same as origination fees?
Both sit in Section A of the Loan Estimate, but they are not the same thing. Points must, by law, be connected to a discounted interest rate. A general origination charge pays for processing the loan and does not have to buy your rate down.
Do points count toward my refinance break-even?
Yes. Points are a true closing cost paid once and never refunded, so they add to the costs your monthly saving has to repay. Test the refinance with the point included and compare against how long you will keep the loan.
Can I buy a fraction of a point?
Yes. CFPB gives examples of 0.5 and 0.125 points. The cost is simply that fraction of 1 percent of your loan amount, so a half point on a $400,000 loan is $2,000.
When do points usually lose?
When the loan ends before the payback month: a move, a sale, or another refinance inside the first few years. They also lose when the rate reduction offered for the point is small, because a small monthly saving stretches the payback month out.
