How to use the mortgage points calculator
Enter base rate (without points)
The standard "par" rate your lender quotes — the rate you'd get without paying any discount points. From your Loan Estimate (Page 1, "Interest Rate"). For mid-2026 conventional 30-yr fixed mortgages, this is typically 6.5-7.5% for prime borrowers.
Enter the buy-down rate (with points)
The lower rate your lender offers if you pay points at closing. From your Loan Estimate alternate quote. Typical: 1 point reduces rate by 0.125-0.25%, so 2 points might lower rate by 0.25-0.50%. The exact reduction varies by lender + rate environment + day.
Enter the points cost (% of loan)
1 point = 1% of loan amount. On a $320K loan, 1 point = $3,200 cash at closing. 2 points = $6,400. Most lenders cap at 2-3 discount points; beyond that, returns diminish quickly. Compare cost vs benefit using the breakeven below.
Enter your expected hold period
Critical input. US median home tenure is ~7-8 years (varies by region + life stage). For couples planning to stay: maybe 10-15 years. For job-mobile professionals: 3-5 years. For "starter homes": 5-7 years. The longer you'll hold, the more points work in your favour.
Read the breakeven verdict
Breakeven = upfront cost / monthly savings. If you hold the loan LONGER than breakeven, points were worth it. If you sell or refinance BEFORE breakeven, you lost money. The verdict box shows: GREEN if hold >> breakeven; YELLOW if marginal; RED if hold < breakeven. Also consider rate trajectory — if rates drop, you'll refinance and points become wasted.
Mortgage points — when paying upfront to lower your rate actually pays off
Discount points are an option offered by mortgage lenders: pay 1% of your loan amount upfront at closing, and they\'ll reduce your interest rate by approximately 0.125-0.25%. The trade-off is simple in concept but tricky in practice — you\'re trading certain upfront cash for uncertain future interest savings. Whether it makes sense depends almost entirely on how long you keep the loan. The breakeven math is straightforward: divide the upfront points cost by the monthly payment savings, and you get the number of months you must hold the loan to break even. Hold longer = profit; sell or refinance before breakeven = loss.
Why most borrowers shouldn\'t buy points
The dirty secret: most homeowners don\'t hold mortgages long enough for points to pay off. The US median home tenure is ~7-8 years, but the median mortgage tenure is shorter — most borrowers refinance within 3-5 years when rates drop, sell within 7-10. Typical points breakeven is 4-7 years — close enough to median tenure that the points-vs-no-points decision is approximately a coin flip. The CFPB\'s own consumer guidance: "Points may not save you money if you don\'t keep the loan long enough." If you\'re uncertain about hold period, or if rates seem high (and likely to fall), skip the points.
Mortgage points are a calculated bet that rates won\'t fall meaningfully during your hold period. In 2022-2024 when rates hit 7-8%, many borrowers paid 2-3 points expecting rates to stay high — then refinanced when rates dropped. They paid for nothing.
When points DO make sense
Three scenarios. (1) Long-term forever-home: planning to stay 15+ years. Points definitely pay off if the rate environment is normal. (2) High rate environment + low rate expectation: if rates seem unlikely to fall further (e.g. already near historic lows), buying down is cheaper than waiting for future refinancing. (3) Tax considerations: discount points on purchase loans are tax-deductible in the year paid (US, if you itemize). For high-bracket earners, this offsets some of the upfront cost. Don\'t buy points if: you might sell/refinance within 5 years, you have higher-return uses for the cash (paying off credit cards, retirement contributions), or rates have meaningfully more room to fall.
ASEAN context
Mortgage discount points are predominantly a US concept. ASEAN markets generally don\'t offer the same explicit point/rate trade-off. Singapore: HDB + bank mortgages have fixed package terms (fixed/floating periods + lock-in fees) but no traditional discount points. Malaysia, Indonesia: same — rate is rate, no buy-down option. The closest parallel: choosing between higher-rate / lower-cost vs lower-rate / higher-fee packages — the breakeven math is identical. Hong Kong, Australia: some lenders offer rate-buy-down products but less standardised than US.
10 Things to Know About Mortgage Points
1 point = 1% of loan, paid in cash at closing. Reduces interest rate ~0.125-0.25% typically.
Breakeven = upfront cost / monthly savings. Hold longer than breakeven = profit.
US median mortgage tenure: 5-7 years — close to typical breakeven, making points a coin flip for many borrowers.
Most lenders cap at 2-3 discount points. Beyond that, returns diminish; rate reduction per point shrinks.
Discount points on purchase loans are tax-deductible in the year paid (US, with itemization).
"Origination points" ≠ "discount points". Origination is lender fee; only discount points buy down the rate.
"Negative points" (credits): some lenders give you cash at closing in exchange for a higher rate. Reverse trade-off.
Points are not refundable if you refinance early. You lose the upfront cost.
2022-2024 rate cycle: many borrowers paid points expecting high rates, then refinanced when rates dropped — wasted money.
Best candidates: long-term holds (10+ years), low-rate-volatility environments, high-bracket borrowers who itemize.
Frequently asked questions
-
Origination points: the lender\'s upfront fee for processing your loan — typically 0.5-1% of loan amount. Doesn\'t reduce your rate; it\'s just compensation to the lender. Discount points: optional upfront payment specifically to reduce your interest rate. Only discount points provide a rate benefit. The Loan Estimate separates these clearly. This calculator focuses on discount points; origination points are typically a fixed lender fee you can shop around for.
-
For purchase mortgages (US): discount points are typically deductible in the year paid, if you itemize. For refinance mortgages: points must be amortized over the loan term (deduct 1/term per year). Limits: only points on acquisition debt up to $750K (post-2017 TCJA) qualify. Origination points generally aren\'t deductible (they\'re not "interest"). Consult a CPA — rules vary by state and loan type.
-
Some. Different lenders price points differently. Get Loan Estimates from 3-5 lenders showing rate-vs-point trade-offs. Same loan can have 0.125% reduction at lender A vs 0.25% at lender B for the same point cost. Online lenders (Better, Rocket) often have more aggressive point pricing than traditional banks. Negotiate: ask "can you give me 0.25% reduction for 1 point instead of 0.125%?" Sometimes lenders absorb half a point to win the deal.
-
Reverse trade: lender pays YOU cash at closing in exchange for a higher rate. Useful when (a) you\'re short on cash for closing, (b) you expect to refinance/sell soon (the higher rate doesn\'t matter much short-term), (c) the cash credit offsets your closing costs. Math is the inverse of points: figure out how long it takes for the higher monthly payment to exceed the upfront credit. If your hold period exceeds that breakeven, lender credits cost you money.
-
Skip the points. If you refinance before breakeven, points become wasted money. The 2022-2024 rate cycle is a cautionary tale: many borrowers paid 2-3 points expecting rates to stay high — then refinanced when rates dropped to 5-6%. They lost the upfront cost AND missed out on additional rate reduction. As a rule: if there\'s any meaningful possibility rates could fall by 100bps+ during your expected hold, don\'t pay points.
-
No — discount points must be paid in cash at closing. They can\'t be financed into the loan principal. Some lenders structure the deal so closing costs (including points) are technically "covered" by a higher rate (lender credit) — but that\'s functionally the opposite trade. If you don\'t have cash for points, the higher base rate is usually the better path.
-
It doesn\'t — the calculator shows pre-tax cash flows. For high-bracket borrowers who itemize, the after-tax cost of points is lower (because deductible). To estimate: multiply upfront cost by (1 − marginal tax rate). E.g. $6,400 in points at 35% bracket has after-tax cost of ~$4,160. This makes breakeven shorter by the same factor. Consult a CPA for your exact tax situation.
-
Often yes — if it gets you to 20% down (avoiding PMI). Compare: $6,400 in points lowers rate by 0.5% = ~$100/month savings. $6,400 extra down might push you over 20% LTV, eliminating $185-300/month PMI. Avoiding PMI usually wins. Calculate both scenarios with this calculator and our PMI calculator (RT-FIN-226). General rule: prioritise getting to 20% down before considering discount points.
