Points vs a Larger Down Payment: Which Wins
Extra cash at closing can buy discount points (lower rate, same balance) or fund a larger down payment (same rate, smaller balance). Points usually win on monthly payment alone when you stay past break-even, but a larger down payment also builds equity, improves loan-to-value, and can reduce or eliminate private mortgage insurance. For buyers near the 20% down threshold, the down payment almost always wins.
Closing day presents a quiet fork in the road for buyers with extra cash. You can hand the lender $4,000 for a discount point and buy your rate down, or you can add $4,000 to the down payment and borrow less. Both lower the monthly payment. Only one builds equity. Here is how to compare them honestly.
The payment math, side by side
Take a $400,000 loan at 6.75% over 30 years, with $4,000 of extra cash. Option A buys one discount point, cutting the rate to 6.50%. The payment falls from about $2,594 to about $2,528, saving $66 per month, and the break-even is roughly 60 months. Option B adds $4,000 to the down payment, borrowing $396,000 at 6.75%. The payment becomes about $2,568, saving roughly $26 per month, with no break-even to wait for. On payment alone, points win by a clear margin, as long as you stay past month 60.
What the down payment buys that points cannot
The $4,000 added to the down payment becomes $4,000 of equity on day one. It also improves the loan-to-value ratio, which matters in three ways. First, a better loan-to-value can earn slightly better pricing adjustments from the lender. Second, it shortens the path to 80% loan-to-value, the threshold where you can request cancellation of private mortgage insurance. Third, if your down payment crosses the 20% line, PMI disappears entirely, which can save $150 or more per month, far more than any point buydown. Points do none of this. They leave the balance, the equity, and the PMI exactly where they were.
The PMI trump card
For buyers putting down less than 20%, the down payment option has a trump card that usually ends the debate. Suppose you are at 15% down on a $500,000 purchase and have an extra $25,000. Buying points with it saves perhaps $60 to $90 per month after a multi-year break-even. Adding it to the down payment reaches 20%, eliminates PMI of maybe $180 per month starting immediately, and needs no break-even. Near the 20% threshold, the down payment wins almost every time. Our PMI removal guide explains the 80% and 78% thresholds under the Homeowners Protection Act if you are already paying PMI.
Risk and flexibility
Points are a bet on the future: they pay off only if you keep the exact loan past break-even. A refinance or a move before then converts the points into a sunk cost. A larger down payment is not a bet. The equity is yours whether you sell in two years or thirty, and a smaller balance means less interest in every scenario, including a refinance. The down payment is also the more liquid-friendly choice in a downturn, since equity is what protects you if home values fall.
When points still win
Points win the narrow case: you are already at 20% down or otherwise free of PMI concerns, you are confident you will keep the loan well past break-even, and you value the lowest possible required monthly payment. Investors and buyers in high-rate environments who cannot reach the next loan-to-value tier sometimes fall in this camp. Even then, get the per-point rate reduction in writing, because a stingy buydown can erase the advantage.
A practical decision rule
Work through the choices in order. First, can the cash get you to 20% down and kill PMI? If yes, do that. Second, would the cash move you across a loan-to-value pricing tier? If yes, weigh it. Third, run the points break-even against your honest holding period. Only if points survive all three screens should they get the money. Most buyers with extra cash will find the down payment does more work per dollar.
Worked example with PMI in the picture
Add PMI and the down payment's advantage compounds. Take a $500,000 purchase at 6.75% with 10% down: a $450,000 loan with PMI around $200 per month. You have an extra $25,000. Option A buys roughly two discount points, cutting the rate toward 6.25% and saving perhaps $140 per month after a long break-even, while PMI continues. Option B lifts the down payment to 15%, shrinking the loan to $425,000, cutting the payment by about $160 per month immediately, and, critically, shortening the road to 20% and PMI cancellation. Option C, if you can stretch slightly more or negotiate, reaches 20% and deletes PMI entirely, saving $200 per month from day one plus the smaller-loan savings. Near the PMI boundary, down payment dollars do triple duty: smaller balance, better loan-to-value, and an earlier PMI exit.
The liquidity argument
There is one honest case for points over down payment even when the math is close: required monthly payment. Points permanently lower the required payment, which helps with debt-to-income qualification and monthly budgeting. A larger down payment lowers the payment too, but by less per dollar, as the worked examples show. If you are near a debt-to-income limit for approval, the bigger payment reduction from points can be the difference between qualifying and not. Just be sure the qualification is real affordability, not a stretch: a loan you qualify for only via buydown is a loan worth rethinking.
The blended strategy most buyers overlook
The choice is not always either-or. Many buyers split the cash: enough extra down payment to reach the next loan-to-value tier or the 20% PMI threshold, with the remainder buying points. On a $500,000 purchase at 15% down with $30,000 of extra cash, putting $25,000 down to reach 20% and using $5,000 for points captures the PMI elimination plus a modest rate buydown. The blended approach works because the first dollars of down payment do the most structural work, PMI removal and tier pricing, while the last dollars face diminishing returns and can be redirected to points. Ask your lender to quote the blended scenario alongside the pure ones; the best answer is often a mix.
