A point is prepaid interest. One point equals 1% of the loan amount. On a $500,000 refinance, one point is $5,000. You might pay a full point, a half point, a quarter point, or no points at all.
When points can make sense
Points can work when you expect to keep the mortgage long enough for the lower monthly payment to recover the upfront cost. They can also make sense when the lower payment helps qualify or creates meaningful monthly breathing room.
When points are a red flag
Points get dangerous when they make an advertised rate look better than it really is. A rate quote with heavy points should not be compared to a zero-point quote as if they are the same thing.
Ask for a zero-point quote too
A clean comparison usually starts with a no-point option. Then you can decide whether buying the rate down is worth the extra cost. Without that baseline, the “best” rate may simply be the most expensive upfront.
Use the points calculator
The mortgage points calculator should answer one question: how many months until the lower payment pays back the point cost?
Do not compare the rate by itself
A refinance quote is a package. The rate matters, but so do points, lender credits, closing costs, appraisal assumptions, lock timing, and how long the homeowner expects to keep the loan.
A quote with a lower rate can be more expensive if the cost to get that rate takes too long to recover.
Quote questions worth asking every time
- What is the rate with zero points?
- Are lender credits included?
- What are the total closing costs?
- Which costs could still change?
- How long is the break-even period?
- What happens if I sell, move, or refinance again?
The practical test
A good quote should get clearer when you ask questions. If the quote becomes harder to understand, or if the conversation shifts back to the headline rate every time you ask about cost, slow down and compare the structure more carefully.
