Discount Points vs. Bigger Down Payment: Where Should $4,000 Go?
· 7 min read
At closing, many buyers face the same fork: the lender offers to sell you discount points that lower your rate, while your own instinct says a bigger down payment is always safer. Both moves are financially sound — but they behave very differently depending on how long you keep the loan. Here is the complete comparison using real numbers.
The Setup: $500,000 Home, $4,000 to Spend
- Purchase price: $500,000
- Standard down payment: $100,000 (20%), so base loan = $400,000
- Base rate: 6.50%, 30-year fixed
- Extra cash available at closing: $4,000
- Lender's offer: one point costs $4,000 (1% of the loan) and cuts the rate by 0.25% to 6.25%
Option A: Buy One Discount Point
With the rate at 6.25%, the payment on the same $400,000 loan drops:
- Payment at 6.50%: $2,528.27/month
- Payment at 6.25%: $2,462.87/month
- Monthly savings: $65.40
Break-even: $4,000 ÷ $65.40 ≈ 61 months — just over five years.
If you hold the loan for the full 30 years, total interest falls from $510,177 to $486,633: $23,544 saved. That is nearly a six-fold return on the $4,000 — but only if you actually stay.
Option B: Add $4,000 to the Down Payment
Instead, put the cash into the down payment ($104,000 down), shrinking the loan to $396,000 at the original 6.50%:
- Payment: $2,502.99/month (vs. $2,528.27)
- Monthly savings: $25.28
- Total interest saved over 30 years: about $5,101
The immediate return looks modest — but note what else happened: your loan-to-value dropped from 80.0% to 79.2%, you start with more equity cushion against price declines, and none of these benefits depend on how long you stay.
Head-to-Head
| Metric | Option A: Point (rate 6.25%) | Option B: Down payment (loan $396k) |
|---|---|---|
| Monthly payment savings | $65.40 | $25.28 |
| Break-even time | ~61 months | Immediate |
| Interest saved over 30 years | $23,544 | $5,101 |
| Loses value if you sell early? | Yes — before month ~61 | No |
| Loses value if you refinance? | Yes — usually forfeits remaining benefit | No |
| Lowers LTV / builds equity? | No | Yes |
| Tax treatment | Points often deductible in year paid (US) | Not deductible; reduces future mortgage interest deductions slightly |
How to Decide in Three Questions
- Will you realistically keep this loan at least 6–7 years? Yes → the point's long-run math wins decisively. No → take the down payment.
- Could you refinance if rates fall? If a future refinance is likely, points are fragile — refinancing throws away the prepaid rate. Down payment equity survives any refinance.
- Do you need LTV benefits? If dropping below 80% LTV removes PMI or unlocks a better pricing tier, the down payment does double duty that points cannot.
A common middle path: split the difference. Half a point plus a small down payment bump captures some of each benefit without betting everything on staying put.
Frequently Asked Questions
Is it better to buy points or put more down?
It depends on how long you keep the loan. In our example, $4,000 spent on one point saves $65 per month and breaks even in about 61 months, saving roughly $23,500 in interest over 30 years. The same $4,000 as a bigger down payment saves only $25 per month but works immediately, saves about $5,100 over the loan, lowers your LTV from day one, and never depends on staying in the home.
How long does it take for mortgage points to break even?
Divide the cost of the points by the monthly savings they create. One point costing $4,000 that lowers the payment by $65 per month takes about 61 months — just over five years. Sell or refinance before that and you lose money on the deal.
Do discount points affect your loan-to-value ratio?
No. Points reduce your interest rate but do not change the loan amount or LTV. A bigger down payment reduces the loan amount directly, lowering LTV, which can improve your rate tier and helps you avoid PMI thresholds.
Are mortgage points worth it if rates might fall?
This is the hidden risk of points. If market rates drop and you refinance within a few years, you forfeit the long-term benefit you prepaid for and typically lose part of the point cost. If a refinance is plausible soon, a bigger down payment is usually the safer use of the money.
