How to Use This Calculator

This calculator compares two specific loan offers side by side — one without points and one with points — to determine whether paying for the rate reduction is financially worthwhile. You will need quotes from your lender showing both options.

  1. Loan Amount — Enter the total loan amount for your refinance. This is what the points percentage is applied against. Points are calculated as a percentage of this amount, not your home value.
  2. Rate Without Points — Enter the interest rate your lender offers with no points paid. This is the base "par" rate for your loan.
  3. Rate With Points — Enter the lower interest rate your lender offers in exchange for buying the specified number of points. This must be lower than the rate without points.
  4. Points to Buy — Enter the number of discount points required to get the lower rate. One point = 1% of the loan amount. You can enter fractional points like 0.5 or 1.25.
  5. Loan Term — Select the new loan term. This affects both monthly payments and total interest calculations.
  6. Planned Stay (months) — How long you expect to stay in the home before selling or refinancing again. This is the most important variable — points are only worthwhile if you stay past the break-even point. Enter your best estimate, and consider running the calculator at multiple scenarios (e.g., 60, 84, and 120 months).

The calculator shows your upfront points cost, monthly savings, break-even timeline, net savings over your planned stay, and lifetime savings over the full loan term. A green verdict means buying points makes sense for your timeline; red means it doesn't.

What Are Discount Points?

One mortgage discount point equals 1% of your loan amount, paid upfront at closing. Paying points is essentially prepaying interest in exchange for a lower ongoing interest rate. Unlike origination fees — which are lender compensation for processing your loan — discount points directly buy down your interest rate for the life of the loan.

Each point typically reduces your rate by 0.125%–0.375%, though the exact reduction varies significantly by lender, loan type, loan amount, and current market conditions. In some market environments, lenders offer more rate reduction per point (when they're trying to attract volume); in others, the conversion is less favorable. Always ask your lender for the exact rate-to-point conversion they're offering, and don't assume a standard ratio.

Points appear on your Loan Estimate (LE) in Section A, along with origination fees. The key distinction to understand: origination fees are mandatory compensation for processing the loan (though negotiable), while discount points are optional. You choose whether to pay them based on your break-even analysis.

Points vs. Origination Fees — Know the Difference

Confusion between points and origination fees is extremely common. Both appear as dollar amounts on your Loan Estimate, both are paid at closing, and both are sometimes called "points." The critical difference: origination fees compensate the lender for making the loan (you typically cannot avoid these, though you can negotiate them). Discount points optionally purchase rate reductions (you choose whether to pay them based on your break-even analysis).

When shopping lenders, ask each one to separate out discount points from origination fees so you can compare apples to apples. A lender with a lower rate but more points may cost more overall than a lender with a slightly higher rate and no points — or vice versa. The APR (Annual Percentage Rate) factors in both, which is why APR is a better cross-lender comparison than the interest rate alone.

Points Cost vs. Rate Reduction Examples

Points Cost on $350K Loan Typical Rate Reduction
0.5$1,750~0.125%
1.0$3,500~0.25%
2.0$7,000~0.50%
3.0$10,500~0.75%

Rate reductions per point vary by lender, loan program, and market conditions. Use the rates quoted by your actual lender for the most accurate analysis.

How It's Calculated

The points analysis uses a three-step process: calculate the upfront cost, calculate the monthly savings, and determine whether your planned stay exceeds the break-even.

Step 1: Upfront Points Cost

Points Cost = Loan Amount × (Points ÷ 100)
Example: $385,000 × (2 ÷ 100) = $7,700

Step 2: Monthly Payment Savings

Monthly Savings = Payment(rate without points) − Payment(rate with points)
Both calculated using standard amortization formula over the loan term

Step 3: Break-Even and Stay Analysis

Break-Even = Points Cost ÷ Monthly Savings
Net Savings (planned stay) = (Monthly Savings × Stay Months) − Points Cost
Positive net savings = points are worth it for your timeline

Real-World Example

James's Discount Points Decision

James refinances a $385,000 loan for 30 years. His lender offers him two options:

Option A — No points: 6.75%, monthly payment $2,498
Option B — 2 points ($7,700 upfront): 6.25%, monthly payment $2,371
Monthly savings from lower rate: $127
Break-even: $7,700 ÷ $127 = 61 months (5.1 years)

James plans to stay in the home for 10 more years (120 months). Net savings over his planned stay: ($127 × 120) − $7,700 = $15,240 − $7,700 = $7,540 net profit from buying points. Over the full 30-year term, the total interest savings from the lower rate are: ($127 × 360) − $7,700 = $45,720 − $7,700 = $38,020 net lifetime savings.

For James, with a 10-year timeline well past the 61-month break-even, buying 2 points is a clear financial win. If he had only planned to stay 4 years (48 months), buying points would have been a losing proposition — he'd have spent $7,700 but only saved $127 × 48 = $6,096.

Tax Deductibility of Discount Points

Points paid on a refinance are generally not fully deductible in the year paid — unlike points paid on a purchase loan, which may be fully deductible in year one. For refinances, points must generally be amortized (deducted ratably) over the life of the loan. This means the deduction is spread evenly across all loan payments rather than taken all at once.

Example: $7,700 in points on a 30-year loan = $256.67 per year in deductions for 30 years. This only helps you if you itemize deductions and your total itemized deductions exceed the standard deduction (which most taxpayers no longer do under current tax law). If you use proceeds to improve your home, a portion of the points may be immediately deductible — consult a qualified tax professional for your specific situation.

There is one favorable exception: if you use a portion of your refinance proceeds for home improvements, that proportional share of points may be deducted in the year paid rather than amortized. For example, if 30% of your cash-out went to home improvements, 30% of your points might be immediately deductible.

When Points Make Sense and When They Don't

Points Are Worth Paying When:

  • You plan to stay a long time. The longer you stay past break-even, the better the return on your points investment. Borrowers planning a 10+ year stay typically benefit significantly.
  • Your loan amount is large. Points cost more on a large loan, but the monthly savings from the rate reduction also scale proportionally. The dollar savings from a 0.25% rate reduction on $600,000 are much larger than on $200,000.
  • The rate reduction per point is meaningful. If one point buys you 0.375% in rate reduction, it's usually a better deal than if one point only buys 0.125%. Calculate the actual conversion rate before deciding.
  • You have cash available without depleting reserves. Paying points doesn't make sense if it drains your emergency fund or opportunity fund. You need sufficient liquid reserves after paying points and closing costs.
  • You're unlikely to refinance again soon. If rates drop further and you refinance again in 2–3 years, you'll lose the points investment on the current loan.

Points Are NOT Worth Paying When:

  • You might move within 5 years. If your break-even is 48–60 months and you might sell before then, points are a losing proposition.
  • The point-to-rate conversion is poor. If a lender only offers 0.125% rate reduction per point (especially on a smaller loan), the savings rarely justify the cost.
  • You could earn more by investing the upfront cash. At a 7% expected return, $7,700 invested could grow to $15,400+ in 10 years — potentially more than the interest savings from the lower rate. This comparison depends heavily on your actual rate, loan size, and investment risk tolerance.
  • Rates are expected to drop further. If you believe you'll refinance again soon at a lower rate, paying points on today's loan means you're pre-paying interest you'll stop owing when you refinance again.

Common Scenarios

Scenario 1: Retiring Couple — Long Stay, Points Are a Strong Investment

Eleanor and George, both 58, refinance their $420,000 home loan and plan to live there through retirement — at least 20 more years. Their lender offers 6.75% with no points or 6.25% with 2 points ($8,400 upfront). Monthly savings: $141. Break-even: 60 months (5 years). They're staying 240 months. Net savings over their planned stay: ($141 × 240) − $8,400 = $33,840 − $8,400 = $25,440. For them, points are an excellent investment with a clear, predictable return — and they're using cash they'd otherwise leave in a low-yield savings account.

Scenario 2: Young Professional — Likely to Move, Points Are a Loss

Derek, 31, refinances his $295,000 condo loan but expects to buy a larger home in 3–4 years as his family grows. His lender offers 6.875% at par or 6.50% with 1.5 points ($4,425 upfront). Monthly savings: $79. Break-even: 56 months (4.7 years). Derek's realistic stay: 36–48 months. Net savings at 48 months: ($79 × 48) − $4,425 = $3,792 − $4,425 = negative $633. Points are a net loss for Derek. He takes the par rate — lower upfront cost, more flexibility for when he sells.

Scenario 3: Half a Point — Almost Always Worth It

Rachel's lender offers 7.00% at par or 6.875% for 0.5 points ($1,750 on a $350,000 loan). Monthly savings: $30. Break-even: 58 months (4.8 years). Rachel plans to stay 7+ years. Net savings at 7 years (84 months): ($30 × 84) − $1,750 = $2,520 − $1,750 = $770. Small net savings, but the break-even is reasonable. For small point purchases, the break-even is typically shorter and the risk of "losing" on the transaction is lower. Half a point is generally the easiest case for buying down the rate.

Tips and Strategies

Always Ask for Both Quotes Side by Side

When getting lender quotes, always ask for your rate at "par" (zero points) and your rate with 1 point and 2 points. Most lenders will provide all three scenarios on request. Compare the rate reduction you get per point to determine whether the conversion is favorable. Some lenders in competitive environments offer 0.375% per point; others offer as little as 0.125%. The difference dramatically changes your break-even calculation.

Don't Buy More Than 2–3 Points

Diminishing returns typically apply as you buy more points. The first point might buy you 0.25% in rate reduction; a second point might also buy 0.25%; but a third point might only buy 0.125% or less. Calculate the incremental value of each additional point independently. Often the first 1–1.5 points is the best value; beyond that, the math gets less attractive quickly.

Use APR to Compare Across Lenders

Annual Percentage Rate (APR) incorporates both the interest rate and the cost of points (along with other fees) into a single comparable number. When shopping multiple lenders, compare APRs rather than just interest rates. A lender with a 6.25% rate and 2 points might have a higher APR than a lender offering 6.5% with no points — meaning the 6.5% offer is actually cheaper on a cost-adjusted basis if you don't stay past the break-even.

Consider Financing Points Into the Loan

Some lenders allow you to roll discount points into the loan balance rather than paying them upfront. This increases your loan amount and monthly payment slightly, but preserves your cash. If you're on the fence about having enough reserves after closing, this option can make points more accessible — though the true break-even is now longer since you're also paying interest on the financed points amount.

Model Multiple Stay Scenarios

Run this calculator at 3, 5, 7, and 10 years to see how your net savings change across different timelines. This reveals whether the points decision is highly sensitive to your timeline (risky) or robust across a wide range (safer). If the net savings are positive even at 5 years but you're planning 10 years, you have a significant margin of safety in the points decision.

Frequently Asked Questions

What is one mortgage discount point? +
One mortgage discount point equals 1% of your loan amount paid at closing. On a $350,000 loan, one point costs $3,500. In exchange, the lender reduces your interest rate — typically by about 0.25%, though the exact reduction varies by lender, loan program, and current market conditions. Some lenders offer fractional points (e.g., 0.5 or 1.5 points) for incremental rate reductions. Discount points are different from origination points, which are simply a fee for processing the loan with no rate benefit.
How many points is too many? +
Most mortgage professionals consider 2–3 points the practical maximum where the math typically still works. Beyond 3 points, diminishing returns usually mean the break-even timeline becomes too long for most borrowers. However, the right number for you is whatever produces a break-even that you're confident you'll exceed before selling or refinancing again. Always calculate the incremental value of each additional point — don't assume the rate reduction scales linearly beyond 1–2 points.
Are discount points negotiable? +
Yes — to a degree. The rate-to-point conversion is set by the lender's current pricing, which reflects the secondary market for mortgage-backed securities. What is negotiable is whether you pay them at all, and you can shop different lenders for better point-to-rate conversions. Some lenders offer negative points (lender credits) in exchange for a higher rate — the opposite of buying points, where the lender pays some of your closing costs in exchange for you accepting a higher rate. This is worth exploring if you prefer to minimize upfront costs.
Can I finance points into the loan? +
Some lenders allow you to roll discount points into the loan balance rather than paying them at closing, as long as the resulting loan amount doesn't exceed the allowable LTV limits. If you do this, your loan amount increases, your monthly payment increases slightly, and you effectively pay interest on the financed points — which reduces (but doesn't eliminate) the net benefit. This can make points more accessible if you're short on closing cost cash, but extends your true break-even period. Model both scenarios to compare.
What does "negative points" or lender credits mean? +
Negative points (also called lender credits) are the opposite of discount points. Instead of you paying upfront to get a lower rate, the lender pays part of your closing costs in exchange for a higher interest rate. For example, accepting a rate of 7.25% instead of 7.00% might give you $3,500 in lender credits to cover closing costs. This is attractive for borrowers who want to minimize upfront out-of-pocket costs or plan to sell or refinance within a few years. The trade-off is a permanently higher monthly payment for as long as you keep the loan.
Are discount points worth it if I might refinance again? +
Generally no. If you refinance your current loan into a new loan, you stop benefiting from points paid on the previous loan. The break-even clock starts over with each refinance. If you think rates may drop significantly in the next 2–3 years and you might refinance again, paying substantial points today is likely a losing proposition. In a declining rate environment, the smart move is often to take the par rate (no points) now, keep your upfront costs low, and refinance again when rates fall further.
How do I report discount points on my taxes? +
For a refinance, discount points are generally reported on IRS Form 1098, which your lender sends you after year end. On your tax return, you claim the amortized deduction each year — typically 1/30th of the total points if it's a 30-year loan. If you paid the points in a prior year and sold or refinanced the home, you can deduct any remaining un-amortized points in the year of sale or refinance. Because this area involves complex rules, consult a qualified tax professional before claiming any deduction related to discount points.
When are discount points worth buying? +
Discount points are worth buying when your break-even period — the points cost divided by your monthly savings — is shorter than how long you plan to stay in the home. For example, if you pay $4,000 in points and save $80/month, your break-even is 50 months (just over 4 years). If you plan to stay 10 years, you'd net $5,600 in savings beyond break-even. The longer you stay past break-even, the better the investment. Points are generally not worth it if you may sell or refinance again within a few years, or if the rate-to-point conversion is poor.
