How Our Breakeven Engine Works: Rate Buydowns & Opportunity Cost
Input your loan amount, base interest rate, and term. Choose Purchase, Refinance, or ARM mode — each changes how breakeven is calculated.
Pick from −1 (lender credit) through 4 points. Each point = 1% of the loan. The typical rate reduction is 0.25% per point but you can customize it.
Drag the slider from 1–30 years. This is the single most important variable — if you leave before breakeven, points are a net loss.
Enter your marginal tax rate and whether you itemize. The calculator applies IRS Topic 504 rules — purchase points are fully deductible in year 1; refi points must be amortized.
Click Calculate. The tool runs 3-scenario side-by-side comparison, opportunity cost analysis (investing vs. paying points), ARM reset warnings, and a PMI crossover check.

Breakeven (months) = Points Cost ($) ÷ Monthly Payment Savings ($)
📐 Net Savings Over Stay Period
Net Savings = (Monthly Savings × Stay Months) − Upfront Points Cost
📐 After-Tax Points Cost (Purchase Loan)
After-Tax Cost = Points Cost − (Points Cost × Marginal Tax Rate)
Example: 1 point on $400,000 = $4,000 cost. Saves $55/mo. Breakeven = 73 months (6.1 years).

Mortgage Discount Points & IRS Tax Deductibility Frequently Asked Questions
- Discount points are optional and prepay interest to permanently lower your rate. You choose to pay them.
- Origination points are a lender fee for processing your loan — they do not reduce your rate. They are essentially a profit margin built into your closing costs.
- The lender’s current pricing model and margin
- Your loan type (conventional, FHA, VA, jumbo)
- Loan term (15-year vs. 30-year)
- Current market volatility — in volatile markets, the cost per basis point increases
- After-Tax Cost = Points Cost − (Points Cost × Marginal Tax Rate)
- After-Tax Breakeven = After-Tax Cost ÷ Monthly Savings
- Purchase loans: Points are typically fully deductible in the year paid (IRS Topic 504), provided certain conditions are met (primary residence, paid from your own funds, customary in your area).
- Refinance loans: Points must be amortized (deducted proportionally) over the life of the loan. If you refinance again, you can deduct the remaining unamortized amount at that time.
- Standard deduction takers: Mortgage points are not separately deductible if you take the standard deduction.
- The loan is secured by your main home (primary residence)
- Points are an established business practice in your area
- Points paid do not exceed what is generally charged in your area
- You use the cash method of accounting
- Points are computed as a percentage of the loan amount
- Points are clearly shown on the Closing Disclosure
- The funds you used to pay points were not borrowed from the lender (i.e., paid from your own cash, down payment, or seller concessions)
- Second home: Points on a purchase loan for a second home cannot be deducted in full the year paid — they must be amortized over the life of the loan, just like refinance points.
- Investment property: Points are deducted as a business expense (Schedule E), also amortized over the loan term. They reduce your rental income, not your personal AGI.
- 0 points: Best if you plan to stay fewer than 5 years or expect to refinance
- 1 point: Reasonable for 7–10 year stays when breakeven is under 5 years
- 2 points: Only justified for 12+ year stays or high-bracket itemizers
- 3–4 points: Rarely justified unless you are locking in a 30-year rate and certain you’ll never refinance
- Each 0.25% rate reduction saves more dollars per month on a larger base rate, making points more valuable
- But rates are more likely to drop in the future, tempting you to refinance — which kills the points ROI
- VA loans: The seller can pay discount points as part of the 4% concession limit. The buyer can also pay points. VA doesn’t restrict the number of points, but excessive points may cause appraisal complications.
- FHA loans: Discount points are allowed and treated the same as conventional loans for tax purposes. Seller can pay up to 6% in concessions including points.
- USDA loans: Also permit points; seller concessions up to 6% allowed.
Expert Closing Strategies: Lender Credits, PMI & Seller Concessions
In a high-rate environment (7%+), points reduce an already painful payment — but if rates drop 1%+ within 2 years, you’ll refinance and lose unrecovered points. Set a mental “refi trigger” rate. If market rates drop to that level before breakeven, the points were wasted.
In 2026, the standard deduction is $30,000 (married filing jointly). For many buyers, mortgage interest alone doesn’t exceed this threshold. Buying 1–2 points on a large purchase loan adds $4,000–$12,000 in additional Year-1 deductible interest, which may push you over the standard deduction and unlock other itemized deductions too.
Paying 2 points on a $500K loan costs $10,000 upfront. That same $10,000 invested in an S&P index fund (historical 10% CAGR) grows to $25,937 in 10 years — vs. ~$13,200 in interest savings from points. Unless you have a long stay (15+ years) or need the guaranteed monthly payment reduction, investing often wins.
Instead of asking for a $5,000 price reduction, ask for $5,000 in seller-paid points. This is often easier for sellers to agree to (same net proceeds) but gives you a permanent rate reduction worth far more over 10+ years. Check your loan type’s seller concession limits: FHA allows up to 6%; conventional is 3–9% depending on LTV.
If your LTV is between 80–90%, you’re paying PMI (typically $50–$200/month). Using your points budget as additional down payment to push your LTV below 80% eliminates PMI entirely — often a better month-to-month saving than a 0.25% rate reduction. Run the PMI Crossover check in this calculator before committing to points.
