You have some extra cash at closing and two ways to spend it: pay discount points to lower the rate, or put more down to lower the balance. When rates are high, points look tempting because each one buys a bigger payment drop; a larger down payment is less exciting but can eliminate mortgage insurance and never needs to be "recovered." This guide works both options through on the same house, shows the break-even for points, and gives the rule of thumb that falls out of the math.
What a Discount Point Buys
A discount point costs 1 percent of the loan amount and lowers the rate by an amount the lender sets, commonly around 0.25 percentage points per point in normal markets, sometimes less when rates are high and volatile. Points are prepaid interest: you pay now for a lower rate for the life of the loan. They make sense only if you keep the loan long enough for the monthly savings to exceed the upfront cost, which is the break-even period. Points on a purchase are generally deductible in the year paid for itemizers under IRS rules on home mortgage interest; points on a refinance are usually spread over the loan term. Check the current IRS guidance or a tax professional for your case.
What a Bigger Down Payment Buys
A larger down payment lowers the loan balance, which lowers the payment at any rate, and it changes two thresholds. Crossing 20 percent down on a conventional loan removes private mortgage insurance, which on an illustrative 0.5 to 1 percent annual premium is a saving that dwarfs most point purchases. Moving to a lower loan-to-value band can also earn a slightly better rate from the lender's pricing grid even below 20 percent. Unlike points, the down payment is not spent; it is equity you keep, and it does not need to be recovered if you sell or refinance early.
The Break-Even Formula for Points
Break-even months = cost of points ÷ monthly payment reduction. Illustration on a $400,000 loan: one point costs $4,000. If it lowers the rate from 7.000% to 6.750%, the 30-year payment falls from about $2,661 to $2,594, a saving of roughly $67 a month. Break-even is about 60 months, five years. If you expect to sell or refinance sooner than that, the point loses money. In a rising-rate market the second half of that sentence matters: refinancing soon is less likely, so the break-even is more likely to be reached, which is the one argument for points today.
Worked Example: $20,000 Extra on a $500,000 Home
Buyer has $80,000 (16 percent) down and an extra $20,000. Illustrative rate 7.000% on a 30-year fixed.
Option A, points: loan stays $420,000 at 84 percent LTV; $20,000 buys roughly 4.76 points, which at 0.25 per point lowers the rate to about 5.81% (lenders cap points, and the per-point reduction usually shrinks past two or three points, so treat this as an upper bound). Payment falls from about $2,794 to about $2,466, saving around $328 a month. PMI remains, say $175 a month, because LTV is still over 80 percent. Break-even on the points alone: about 61 months.
Option B, down payment: down payment becomes $100,000 (20 percent), loan $400,000 at 7.000%. Payment is about $2,661, saving about $133 a month on principal and interest versus option A's starting point, and PMI of about $175 a month disappears immediately. Total monthly saving about $308, with no break-even period and $20,000 more equity.
The two options land within about $20 a month of each other, but option B keeps the money as equity, removes PMI for good, and does not depend on holding the loan five years. Option A only pulls ahead if the buyer is certain to keep the loan for well over five years and PMI was not in play. Put your own numbers through the Mortgage Calculator twice and compare; the Compare Two Loan Offers tool shows both side by side.
When Points Win
- You are already at or past 20 percent down, so PMI is not a factor.
- You are confident you will keep the loan well beyond the break-even, typically seven years or more in today's pricing.
- The seller is paying the points as a concession; a seller-paid buydown costs you nothing to recover.
- You itemize and the deduction for points in the purchase year has value to you.
- The lender's grid offers an unusually large rate drop per point, which happens occasionally when lenders want volume.
When a Bigger Down Payment Wins
- The extra cash gets you to 20 percent and removes PMI, or to a better LTV band.
- You might sell or refinance within five to seven years.
- You want the flexibility of equity: a recast later can lower the payment again without a new loan.
- Rates are more likely to fall than rise over the next few years, which would make today's purchased rate reduction worth less.
- You do not itemize, so the points deduction is worth nothing to you.
A Third Option: Keep the Cash
Neither points nor a larger down payment is right if the $20,000 is your entire reserve. Lenders like to see reserves, and a buyer with no cushion after closing is one furnace repair from a missed payment. The DTI Calculator helps you see whether the payment leaves room; if it does not, the cash belongs in savings, not in the rate.
Frequently Asked Questions
Q: Is it better to pay points or put more money down?
A: In most cases where the extra cash reaches 20 percent down and removes mortgage insurance, the larger down payment wins: the saving starts immediately, there is no break-even period, and the money stays as equity. Points win when PMI is not a factor and you will keep the loan well past the break-even, typically seven years or more.
Q: How much does one discount point lower the rate?
A: Commonly about 0.25 percentage points per point in normal markets, less when rates are volatile, and the reduction per point usually shrinks after the first two or three points. Ask the lender for the exact grid; it varies.
Q: How do I calculate the break-even on points?
A: Divide the cost of the points by the monthly payment reduction they produce. The result is the number of months you must keep the loan for the points to pay off.
Q: Are discount points tax deductible?
A: Points paid on a home purchase are generally deductible in the year paid if you itemize, under IRS rules for home mortgage interest; points on a refinance are usually deducted over the loan term. Confirm current rules with the IRS or a tax professional.
