Understand mortgage discount points: what they cost, how much you save, and when they make sense. Break-even math with real numbers from a CA broker.
One of the most confusing parts of refinancing is whether to pay "points" to buy down your interest rate. Lenders love to throw around terms like "discount points" and "origination points" without explaining what you're actually paying for.
Let me cut through the confusion. After 15 years brokering mortgages, I can tell you exactly when points make sense—and when you're better off keeping that cash in your pocket.
One discount point = 1% of your loan amount, paid upfront at closing to reduce your interest rate.
On a $400,000 loan:
How much does your rate drop? Usually 0.25% per point, but it varies by lender and market conditions. Sometimes you get 0.125% per point, sometimes 0.375%. You have to ask.
Loan amount: $400,000 No points: 6.50% rate → $2,528/month 1 point ($4,000): 6.25% rate → $2,463/month 2 points ($8,000): 6.00% rate → $2,398/month
You're paying $4,000 upfront to save $65/month, or $8,000 to save $130/month. The question is: Is that a good investment?
Discount points buy down your rate. You pay them, you get a lower rate.
Origination fees (sometimes called "origination points") are just lender fees. You pay them, you get nothing except the privilege of borrowing from that lender.
Never confuse the two. If a lender quotes "1 point" but your rate doesn't drop, that's an origination fee, not a discount point. Shop elsewhere.
Here's how you know if points make sense:
Break-even months = Cost of points ÷ Monthly savings
If you keep the loan longer than 62 months, you come out ahead. If you sell or refinance before that, you lost money on the points.
Wait—same break-even? Sometimes that happens. The second point gave you the same 0.25% rate drop as the first point. Whether you pay 1 point or 2 points, you break even in the same timeframe. In this case, if you're staying longer than 5 years, you might as well pay both points and maximize your savings.
But this isn't always true. Sometimes the second point only gets you 0.125% instead of 0.25%. Always run the numbers.
If you're keeping this loan for 10-15 years or longer, paying points is usually smart. You'll blow past the break-even point and save thousands over the life of the loan.
Real client scenario: Refinanced $500,000 at 6.25% with 2 points ($10,000). Could have gone no-points at 6.75%. Break-even was 64 months. They're still in the house 8 years later, and they've saved $22,000 beyond their initial $10,000 cost.
Discount points are tax-deductible in the year you pay them if it's a purchase. On a refinance, you have to amortize the deduction over the life of the loan.
Example: You pay $8,000 in points on a 30-year refinance. You can deduct $267/year ($8,000 ÷ 30 years). At a 24% tax bracket, that's $64/year in tax savings, or about $5/month.
Not huge, but it adds to the benefit. (Check with your CPA—I'm a broker, not a tax advisor.)
If you have $10,000 sitting in a savings account earning 4.5%, but you can buy down your rate from 6.75% to 6.25%, you're better off paying the points.
Math:
Points are a better return than most savings accounts or CDs right now.
If you expect rates to keep climbing, locking in the lowest possible rate today—even if it costs you upfront—protects you from higher rates later.
In 2022, when rates were spiking, I had clients pay 3 points to lock in 5.5% instead of 6.5%. Seemed crazy at the time. By mid-2023, market rates hit 8%. They looked like geniuses.
If you're moving, downsizing, or expecting to refinance again soon, you won't hit your break-even point.
Example: You pay $6,000 in points with a 60-month break-even. You sell after 3 years. You saved $2,340 in interest ($65/month × 36 months) but spent $6,000. Net loss: $3,660.
If paying points means draining your emergency fund or going into debt elsewhere, don't do it. The monthly savings isn't worth the financial stress.
Keep 3-6 months of expenses in cash. Points can wait.
I generally don't recommend points if the break-even is longer than 7 years. Too much can change—you might move, refinance again, or rates might drop.
Rule of thumb: If break-even exceeds your realistic time horizon by more than 50%, skip the points.
These streamlined refinances are designed to be low-cost. Paying points defeats the purpose. Most of my streamline clients go no-points because the whole appeal is speed and simplicity.
Sometimes the best strategy is to take the market rate and keep your cash.
When I recommend no-points:
Client was refinancing $450,000. Options:
They were planning to sell in 4 years to move closer to family. I said skip the points. They did. Sold after 3.5 years. Saved themselves $4,500.
Here's the reverse: instead of paying points to lower your rate, you can accept a higher rate and get a lender credit that covers your closing costs.
Example:
You're paying 0.50% more in rate, but you're not bringing any cash to closing.
When this makes sense:
When it doesn't:
My take: Lender credits are great for short-term plays or when cash is king. But if you're staying long-term, you're better off paying closing costs upfront and taking the lower rate.
Lenders will quote you different combinations of rate and points. Here's how to compare apples to apples:
Use a mortgage calculator. Don't trust your mental math on this.
Divide the cost of points by the monthly savings. That's your break-even in months.
If you're planning to stay 10 years, calculate total payments for each scenario over 120 months.
Example:
If you're staying 10 years, Option B wins. If you're selling in 3 years, Option A wins.
Insider knowledge: Lenders have "rate sheets" showing all possible rate/point combinations. They don't always share this. You have to ask.
When I quote a client, I show them 3-4 options:
Then we talk about their plans and pick the one that fits.
Pro tip: Ask your lender for the full rate sheet. If they won't share it, they're not being transparent. Shop elsewhere.
Let's run a 30-year comparison on a $400,000 loan:
If you keep the loan all 30 years, those points pay off big. But most people don't keep a loan 30 years. The average mortgage lasts 7-10 years before refinancing or selling.
Yes. Points are negotiable. If one lender quotes 0.25% per point and another quotes 0.125%, shop around. Pricing varies by lender.
Absolutely. You can pay 0.5 points, 0.75 points, 1.375 points—whatever. It's not limited to whole numbers.
No. Points are part of closing costs, but closing costs also include appraisal, title, escrow, lender fees, and more. Don't confuse the two.
Technically yes, but you're defeating the purpose. You're borrowing money to buy down the rate on the money you're borrowing. It's circular. If you're financing points, just take the higher rate and skip the points.
Most do, but some online lenders or "low-cost" lenders don't. They lock in one rate and that's it. If you want points, shop with traditional lenders or brokers.
Here's what I tell clients:
Never pay points just because the lender pushes it. They make the same money either way. This decision is about your timeline and your finances.
And always—always—run the break-even math before deciding.
