Mortgage Points Explained: When Paying Upfront Actually Pays Off

Mortgage points come in two kinds that get conflated: discount points, which buy down your rate, and origination charges, which are the lender's fee and buy you nothing. This guide focuses on discount points — the one that can save real money if you stay long enough.

The Basic Math

• One discount point = 1% of the loan amount, paid at closing.
• It typically lowers the rate by roughly 0.25 percentage points (the exact amount is quoted at lock).
• The cost is upfront; the benefit is a lower payment every month for as long as you keep the loan.

Example on a $300,000 loan:

| Choice | Rate | Upfront cost | Monthly P&I (30-yr) | |--------|------|--------------|----------------------| | No points | 6.50% | $0 | ~$1,896 | | 1 point | 6.25% | $3,000 | ~$1,847 | | 2 points | 6.00% | $6,000 | ~$1,799 |

The Break-Even Test

Buying points only pays off if you keep the loan past the point where monthly savings repay the cost.

Break-even months = point cost ÷ monthly savings

For 1 point ($3,000) saving about $49/month: $3,000 ÷ $49 ≈ 61 months, or about five years.

• Keep the loan longer than five years → the points save you money.
• Sell or refinance sooner → you lost money on the points.

When Points Make Sense

1. You will stay a long time. The longer you keep the loan, the more the lower rate compounds in your favor.
2. You have cash to spare at closing. Points are paid upfront, so they compete with your down payment and reserves.
3. Rates are relatively high. When market rates are elevated, a permanent buydown locks in a better rate for the life of the loan — useful if you do not expect to refinance soon.

When Points Do Not Make Sense

1. You may move or refinance within a few years. You never reach break-even.
2. You would rather keep cash for down payment or reserves. A larger down payment can lower your rate on its own.
3. The buydown is small. A 0.125-point rate drop for $3,000 has a very long break-even and rarely wins.

Points vs Lender Credits

The mirror image of points is a lender credit: you accept a higher rate in exchange for the lender covering some costs. If you are certain you will refinance soon, a credit (higher rate, lower closing cost) can beat paying points. The two are opposite bets on how long you keep the loan.

Watch the APR

Each point widens the gap between your note rate and your APR. A loan with points shows a lower note rate but a higher APR than a no-points loan at the same headline. Compare both, and match the structure to your time horizon.

The Practical Move

Ask each lender for both a zero-point quote and a costed points quote. Compute the break-even on the difference, then compare it to how long you realistically expect to keep the loan. If the break-even lands inside your plan, points are a rational buy; if not, keep the cash.
