Mortgage Points Break-Even Calculator:
Cost of Points, Monthly Savings, Break-Even Timeline, and Reverse Lender Credit Strategy
Buying 2 discount points on a $320,000 mortgage costs $6,400 at closing and reduces the rate from 6.80% to 6.30% — saving $106/month and reaching break-even in exactly 60 months (5 years). If you hold the loan longer than 5 years, points save money: $6,440 net savings at 10 years, $31,760 over the full 30-year term. If you sell or refinance in under 5 years, the $6,400 upfront cost is not recovered. The reverse strategy — lender credits — pays you $3,200 at closing in exchange for a 7.125% rate ($69/month more), and reaches its own break-even at 46 months: ideal for buyers confident they will move or refinance within 4 years.
Mortgage discount points are prepaid interest — a fee paid at closing in exchange for a permanently lower interest rate on the loan. The mechanics are simple: one point costs 1% of the loan amount and typically reduces the rate by 0.125% to 0.25% (the exact reduction varies by lender and market). The financial question is equally simple: will you hold the loan long enough to recover the upfront cost through lower monthly payments? The break-even formula — cost of points divided by monthly savings — produces the minimum holding period required to justify the purchase. Below that threshold, points are a money-losing proposition. Above it, the savings compound indefinitely for as long as the loan remains outstanding.
The reverse strategy — lender credits — runs the identical math in the opposite direction. Instead of paying extra at closing to reduce the rate, the borrower accepts a higher rate in exchange for a cash credit from the lender applied toward closing costs. A 7.125% rate on a $320,000 loan costs $69 more per month than the 6.80% par rate, but produces a $3,200 credit at closing. The lender credit break-even is 46 months: if the loan is refinanced or the property sold within 46 months, the borrower captured the credit without fully paying for it through the higher monthly payments. The lender credit strategy is specifically designed for borrowers who expect their ownership or rate environment to change within 3-5 years — and represents a legitimate counterpart to the discount points strategy for long-term borrowers.
Three Mortgage Points Formulas: Cost, Monthly Savings, and Break-Even
1. COST OF DISCOUNT POINTS
2. MONTHLY PAYMENT SAVINGS FROM RATE REDUCTION
M = Loan x r x (1+r)^360 / ((1+r)^360 – 1) where r = monthly rate
3. BREAK-EVEN MONTHS (AND TOTAL SAVINGS AT HOLD PERIOD)
Net Savings = (Monthly Savings x Hold Months) – Cost of Points [positive = profitable]
The break-even formula’s simplicity conceals an important nuance: it assumes the loan stays outstanding at the discounted rate for the entire measurement period. In practice, refinancing resets the clock — if you buy 2 points in 2026 and refinance into a lower rate in 2028 (24 months later), you recouped only $106 x 24 = $2,544 in savings against the $6,400 cost, a $3,856 net loss. This is why the probability of refinancing before break-even is the most critical variable in the points decision: in a rate environment where rates may decline, the refinancing option erodes the value of buying points today to lock in a rate reduction on a loan you may replace in 18-36 months.
Four Points Scenarios: Cost, Payment Savings, Break-Even, and Lender Credits
The fourth card’s lender credit strategy reveals an important asymmetry: the break-even for lender credits (46 months) is shorter than the break-even for discount points (60 months) in this example. This reflects the difference in the magnitude of the rate change: lender credits only provide 0.325% rate increase for $3,200, while discount points provide a 0.50% rate decrease for $6,400. Both strategies have their own optimal hold period. When shopping lenders, it is valuable to compare quotes across the full rate-and-points spectrum: some lenders may offer better value at par rate, others at one point down, others with lender credits. The goal is to maximize net present value across the expected hold period, not simply to minimize the initial monthly payment.

The data block’s third-year loss ($2,584) and seventh-year gain ($2,504) frame the decision clearly: this is a bet on staying in the home or keeping the loan for more than 5 years. The median time US homeowners stay in their home is approximately 8-13 years in most markets (higher in slower-appreciation markets, lower in high-appreciation, high-mobility metros). If you are purchasing in a location where you expect to stay 8-10 years, the 5-year break-even is comfortable. If you are purchasing with a planned 3-5 year horizon (career move, growing family, relocating for retirement), the math does not support buying points.
1, 2, and 3 Points Compared: Cost, Savings, and Break-Even on $320,000
| Points | Cost | Rate | Monthly Payment | Monthly Savings vs No Points | Break-Even | Net Savings: 7yr | Net Savings: 10yr |
|---|---|---|---|---|---|---|---|
| 0 (par rate) | $0 | 6.80% | $2,087 | Baseline | N/A | $0 | $0 |
| 1 point | $3,200 | 6.55% | $2,033 | $54/month | 59 months (4.9yr) | +$1,216 | +$3,280 |
| 2 points | $6,400 | 6.30% | $1,981 | $106/month | 60 months (5.0yr) | +$2,504 | +$6,320 |
| 3 points | $9,600 | 6.05% | $1,930 | $157/month | 61 months (5.1yr) | +$3,588 | +$9,240 |
| $320,000 loan, 30-year fixed rate. Rate reduction: 0.25% per point (typical estimate — confirm with your lender). Monthly payments calculated using standard amortization formula. Break-even = Cost / Monthly Savings. Net Savings = (Monthly Savings x Months) – Cost. Note that all three point scenarios have nearly identical break-even periods (59-61 months): this is because each additional point adds the same proportional cost ($3,200) for the same proportional rate reduction (0.25%), producing the same ratio. If the rate reduction per additional point diminishes (e.g., the 3rd point buys only 0.20% instead of 0.25%), the break-even for 3 points lengthens relative to 1 or 2 points. Always confirm the marginal rate reduction for each additional point with your lender before assuming a constant 0.25% per point. | |||||||
The comparison table’s nearly identical break-even periods (59-61 months) for 1, 2, and 3 points is the most instructive pattern: when the rate reduction per point is constant, buying more points produces proportionally more savings at the same time cost. This means if the break-even is acceptable for 1 point, it is equally acceptable for 2 or 3 points — and the marginal savings from each additional point are identical in percentage terms. The real driver of point value is not how many points you buy but whether the break-even period aligns with your hold period. In practice, lenders sometimes offer diminishing rate reductions for additional points (the 3rd point buys only 0.20% instead of 0.25%), which lengthens the break-even for higher point quantities — always ask your lender for the incremental rate reduction for each additional point before calculating.
Net Savings by Hold Period: 0, 1, 2, and 3 Points on $320,000
| Hold Period | 0 Points Net | 1 Point Net | 2 Points Net | 3 Points Net | Best Choice |
|---|---|---|---|---|---|
| 1 year (12 mo) | $0 | -$2,552 | -$5,128 | -$7,716 | 0 Points (no points) |
| 3 years (36 mo) | $0 | -$1,256 | -$2,584 | -$3,948 | 0 Points |
| 5 years (60 mo) | $0 | +$40 | +$40 | +$20 | Near break-even all |
| 7 years (84 mo) | $0 | +$1,216 | +$2,504 | +$3,588 | 3 Points (most savings) |
| 10 years (120 mo) | $0 | +$3,280 | +$6,320 | +$9,240 | 3 Points |
| 15 years (180 mo) | $0 | +$6,520 | +$13,160 | +$19,550 | 3 Points |
| 30 years (360 mo) | $0 | +$16,240 | +$31,760 | +$46,620 | 3 Points (max savings) |
| Net savings = (Monthly Savings x Hold Months) – Cost of Points. 1 point: $54/month savings – $3,200 cost. 2 points: $106/month – $6,400. 3 points: $157/month – $9,600. All break-even near 60 months (5 years) due to constant rate reduction per point. Negative values = point purchase was a financial loss (should have chosen 0 points). For any hold period above 5 years, more points produce more net savings — assuming constant rate reduction per point and no refinancing. Key decision rule: estimate your expected hold period for this specific loan (not just this home), then choose points accordingly. If refinancing probability in next 3 years exceeds 40%, 0 points or lender credits are likely the better financial decision. | |||||
The hold period table reveals the most important rule for mortgage points decisions: there is no intrinsically “right” number of points — there is only the right number given your specific expected hold period. For a buyer planning to stay 15+ years in a stable career and community, 3 points at a constant break-even produces $19,550 more in net savings than 1 point over 15 years. For a buyer with a 3-year planned horizon (before a planned move or refinance), all points scenarios are financial losses relative to accepting the par rate. The break-even analysis removes the emotion from this decision and reduces it to a single comparison: “How long do I plan to keep this specific loan?”
Net Savings Over Time: 2 Points vs 0 Points on $320,000 Loan
The growth bars make the points decision visual and immediate: losses at 3 years, break-even at 5 years, and progressively larger gains thereafter. The linear accumulation pattern (each additional year adds $1,272 in net savings after break-even) is a useful mental model for long-term owners: holding the points loan 6 years instead of 5 adds $1,272; holding 10 years instead of 5 adds $5,300 in net savings. The compounding is linear rather than exponential because the savings are fixed at $106/month — but the opportunity cost comparison is more complex if the $6,400 in points could have earned investment returns elsewhere. At 7% annual investment return on $6,400, the alternative investment would be worth approximately $10,279 at 7 years — somewhat more than the $2,504 net savings from points, suggesting that points should not be evaluated purely against zero alternative return but against what else the $6,400 could earn.
Lender Credits: The No-Closing-Cost Mortgage Strategy
Lender Credits: When Taking a Higher Rate at Closing Is the Smarter Choice
Lender credits (negative points) work in reverse: by accepting a rate above par (the market rate for no points), the borrower receives a cash credit from the lender at closing. On $320,000 at par rate 6.80%, a lender might offer: accept 7.125% and receive $3,200 in lender credits ($160 per basis point, 32.5 basis points at $100/basis). Monthly cost: $2,156 vs $2,087 = $69/month more. Break-even: $3,200 / $69 = 46 months. If the loan stays outstanding less than 46 months (you sell or refinance), the lender credit was free money — you received $3,200 and paid back only $69 x (months held) in higher payments. If held past 46 months, the higher monthly payments exceed the initial credit, making par rate or discount points the superior choice. Lender credits are most appropriate for: (1) Buyers who expect to move within 3-5 years and cannot definitively commit to a longer hold. (2) Buyers who are cash-constrained at closing and need the credit to cover other closing costs or maintain reserves. (3) Buyers who believe rates will decline significantly within 2-3 years, making a refinance likely before break-even. The lender credit is NOT free money in perpetuity — it is an advance from the lender on future higher-rate payments. Treat it as a short-term bridge, not a long-term rate strategy.
Points vs Alternative Uses of the Same Cash
The True Cost of Points: Opportunity Cost Comparison
Before buying mortgage points, compare the $6,400 to its best alternative use: (1) High-interest debt payoff: $6,400 applied to credit card debt at 22% APR saves $1,408/year in interest — 10.8x more than the $106/month points save. Never buy points while carrying high-interest consumer debt. (2) Emergency fund: if buying points depletes your emergency fund below 3-6 months of expenses, the financial risk from an unplanned expense exceeds the long-term points savings. Maintain the reserve fund before purchasing points. (3) Investment return: $6,400 at 7% annually compounding for 10 years = $12,590. The 2-point scenario provides $6,320 in net savings at 10 years — slightly less than the investment alternative. Points are a reasonable alternative to investing only when the expected hold period is certain, the alternative investment is at typical market returns (not high-risk), and the borrower has no higher-priority debt uses. (4) Larger down payment: $6,400 added to a 20% down payment eliminates PMI sooner on a borderline LTV and reduces the loan principal permanently — potentially more valuable than the rate reduction for borderline PMI situations.
Mortgage Points Decision Checklist
Frequently Asked Questions: Mortgage Points Break-Even Calculator
How do mortgage points work?+
One discount point = 1% of the loan amount paid at closing in exchange for a permanently lower interest rate. 1 point typically reduces rate by 0.125%-0.25% (confirm with your lender). $320,000 loan: 2 points = $6,400 cost. Rate: 6.80% to 6.30% (0.25% per point). Monthly savings: $2,087 – $1,981 = $106/month. Break-even: $6,400 / $106 = 60 months (5 years). After 5 years, every month adds $106 in net savings. Full 30-year savings: $31,760 net. Points are paid at closing and cannot be refunded — if you refinance or sell before break-even, the unrecovered upfront cost is a permanent loss.
How do you calculate the mortgage points break-even?+
Break-Even Months = Cost of Points / Monthly Savings. Step 1: Cost = Loan x Points%. $320,000 x 2% = $6,400. Step 2: Monthly savings = M(base rate) – M(discounted rate). M = Loan x r x (1+r)^360 / ((1+r)^360 – 1). At 6.80%: $2,087. At 6.30%: $1,981. Savings: $106/month. Step 3: Break-even = $6,400 / $106 = 60 months. Step 4: Net savings at hold period H = ($106 x H) – $6,400. If H = 84 months (7yr): $106 x 84 – $6,400 = +$2,504. Key input: rate reduction per point (0.25% in this example — confirm with your lender). After-tax break-even for itemizers: ($6,400 x (1 – tax rate)) / $106 — for 25% rate: $4,800 / $106 = 45 months.
How much does 1 point reduce the mortgage rate?+
Typically 0.125% to 0.25% per point, varying by lender, loan type, and market. Not a fixed constant — confirm your lender’s specific pricing. At 0.25% per point on $320,000 at 6.80%: 1 point ($3,200) reduces to 6.55%, saves $54/month, break-even 59 months. 2 points ($6,400) reduce to 6.30%, save $106/month, break-even 60 months. 3 points ($9,600) reduce to 6.05%, save $157/month, break-even 61 months. The dollar savings per month of rate reduction are larger at higher loan amounts and higher rates (each 0.25% saves more dollars on a $500,000 loan than a $200,000 loan). Always request the specific rate-to-points table from your lender, as the marginal benefit can diminish after 2-3 points.
When should you not buy mortgage points?+
Do NOT buy points when: (1) Expected hold period below break-even (less than 5 years for typical 60-month break-even). (2) High-interest consumer debt exists ($6,400 paying 20% APR credit card saves more than points). (3) Cash constraints — buying points depletes emergency fund below 3-6 months of expenses. (4) Rate decline expected — if rates may fall 0.75%+ in 2-3 years, refinancing resets the break-even clock and points are likely unrecoverable. (5) Down payment is below 20% — use extra cash to reach 20% and eliminate PMI first (PMI elimination provides larger monthly savings than typical points purchase on borderline-down-payment scenarios). (6) Seller inflated price to fund concessions — evaluate base price independently.
What are lender credits for mortgages?+
Lender credits = negative points. Borrower accepts higher rate in exchange for cash credit at closing. $320,000 example: accept 7.125% (vs par 6.80%) and receive $3,200 credit. Monthly cost: +$69/month above par rate. Break-even: $3,200 / $69 = 46 months. Under 46 months: credits win (net gain). Over 46 months: par rate wins. Use lender credits when: expecting to sell or refinance within 3-4 years, cash-constrained at closing, or believing rates will decline significantly (triggering a refinance before break-even). Common in “no-closing-cost” mortgages where all closing costs are funded by lender credits at the cost of a permanently higher rate. Not appropriate for long-term homeowners who will pay the higher rate for decades.
Are mortgage points tax deductible?+
Purchase points on primary residence: fully deductible in year paid for itemizers (must exceed standard deduction of $29,200 for married filing jointly in 2025). Reduces effective cost: at 25% marginal rate, $6,400 in points costs $4,800 after-tax, shortening break-even from 60 to 45 months. Refinance points: must be amortized over loan life (divided by months and deducted monthly). If refinancing again or paying off, remaining un-deducted points deductible in that year. Rental property points: deductible as business expense, amortized over loan term. The deductibility benefit applies only to itemizers — the standard deduction is $29,200 (MFJ 2025) and many middle-income homeowners no longer itemize since the TCJA 2017 expansion of the standard deduction. Confirm deductibility with your CPA for your specific situation.
Is it better to buy points or put more down?+
If below 20% down: always prioritize reaching 20% to eliminate PMI before buying points. PMI on $320,000 at 19% down vs 20% down = approximately $150-200/month in PMI savings when crossing the threshold — 1.4-1.9x more monthly savings than buying 2 points ($106/month). At 20%+ down: compare monthly impact. $6,400 extra down on $320K loan reduces balance to $313,600: new payment = $2,046 (vs $2,087). Monthly reduction from extra down: $41. Monthly reduction from 2 points: $106. Points reduce monthly payment more per dollar at typical rates. But extra down builds equity immediately — useful for refinancing, HELOC access, or eventual sale equity. Hybrid: consider a portion to additional down payment (if near key LTV threshold) and remainder to points (if above 20% with comfortable cushion).
Can I roll mortgage points into the loan?+
Generally no for purchase loans — mortgage points paid to reduce the rate must be paid from closing funds, not added to the loan balance. Adding discount points to the loan would be circular (borrowing more to pay for a lower rate on the amount you borrowed). For refinances, some programs allow rolling closing costs including points into the new loan balance — but this increases the loan amount and partially offsets the rate reduction savings. Example: $320,000 refinance with 2 points. Roll $6,400 into loan: new balance $326,400 at 6.30% vs original $320,000 at 6.80%. Monthly payment comparison: $326,400 at 6.30% = $2,023 vs $320,000 at 6.80% = $2,087. Savings $64/month (less than the $106 from points paid cash). Break-even for rolled-in points: $0 upfront but smaller savings. Net result at 7yr: $64 x 84 = $5,376 savings minus additional principal ($6,400 at interest) = more complex but generally less favorable than paying points from cash.
How do seller-paid points work?+
Seller-paid points (concessions) allow the seller to pay discount points on behalf of the buyer. The seller credits 2% of loan ($6,400) toward the buyer’s points at closing, reducing the buyer’s out-of-pocket while lowering the rate to 6.30%. The buyer gets the lower rate without the cash cost. Limits: conventional loans allow 3% seller concessions at LTV 90-95%, 6% at LTV below 90%. FHA allows 6% seller concessions. VA allows unlimited. Why it can work: sellers may prefer to concede on price structure rather than purchase price — or buyers may negotiate a higher purchase price with seller covering points. Warning: be careful not to overbid on the purchase price to fund seller-paid concessions. If the home is worth $400,000 and you offer $406,400 with seller paying $6,400 in points, you overpaid $6,400 and took a larger loan — partially negating the rate reduction savings. Always evaluate seller concessions against the true fair market value of the property independently.
Key Takeaways
Mortgage discount points are a prepaid interest buy-down: 1 point costs 1% of the loan amount and typically reduces the rate by 0.125% to 0.25%. On a $320,000 loan at 6.80%, buying 2 points costs $6,400, reduces the rate to 6.30%, and saves $106/month — reaching break-even in exactly 60 months. Below 60 months of loan duration, points produce a financial loss; above 60 months, net savings accumulate at $106/month reaching $6,320 at 10 years and $31,760 over the full 30-year term.
The three most important points decision principles are: calculate the break-even using your lender’s specific rate reduction per point (not the generic 0.25% estimate), never buy points while carrying high-interest consumer debt (which offers far higher guaranteed returns on the same cash), and evaluate the after-tax break-even for itemizers (reducing 60 months to approximately 45 months at a 25% marginal rate). The reverse strategy — lender credits — is appropriate for buyers with shorter expected hold periods or cash constraints, providing closing-cost funding in exchange for a permanently higher rate whose break-even arrives at approximately 46 months in this example. Neither strategy is universally superior: the optimal choice depends entirely on expected loan duration, cash constraints, and the specific rate-to-points pricing offered by your lender.
