Mortgage Points Calculator

Paying upfront fees to lower your mortgage rate can save tens of thousands of dollars over the life of a loan — or cost you money if you sell or refinance too soon. This calculator compares the cost of buying discount points against the monthly savings they generate, showing your break-even timeline and total net savings so you can decide whether buying points makes sense for your situation.

How Mortgage Points Are Calculated

Each discount point costs 1% of the loan amount. The rate reduction per point varies by lender, but 0.25% is the most common figure. The formulas are:

• Cost of points = Loan Amount x (Number of Points / 100)
• New rate = Base Rate - (Points x Rate Reduction Per Point)
• Monthly savings = Payment(base rate) - Payment(new rate)
• Break-even months = Cost of Points / Monthly Savings
• Net savings over term = (Monthly Savings x Loan Term in Months) - Cost of Points

For example: $300,000 loan, 1 point at $3,000, rate drops from 6.75% to 6.50%. Monthly payment falls from $1,946 to $1,896 — a $50/month saving. Break-even = $3,000 / $50 = 60 months (5 years). Net 30-year savings = $18,000 - $3,000 = $15,000.

Worked Examples

Example 1 — Long-term homeowner, $400,000 loan. Base rate 7.00%, buying 1 point for $4,000, new rate 6.75%. Monthly payment drops from $2,661 to $2,594, saving $67/month. Break-even = 60 months. Staying 10 years nets $4,040 after costs; staying 30 years nets $20,120.

Example 2 — Likely to move in 4 years, $300,000 loan. Base rate 6.75%, buying 1 point for $3,000, monthly savings $50. Break-even is 60 months — after only 48 months (4 years) you have saved $2,400 against $3,000 paid. Net result: -$600. Points are not worthwhile here.

Example 3 — Jumbo buyer, $800,000 loan, 2 points. Cost = $16,000. Rate drops from 7.00% to 6.50%. Monthly P&I falls from $5,322 to $5,060, saving $262/month. Break-even = 61 months. Over 30 years: $94,320 gross savings minus $16,000 cost = $78,320 net — a strong case for buying points on a large loan.

When to Use This Calculator

• You have received a rate sheet from a lender showing different rate/point combinations and want to compare them side by side.
• You are deciding how to allocate closing cost funds between a larger down payment and buying down the rate.
• You plan to hold the mortgage for 7+ years and want to quantify the long-term savings from a lower rate.
• You are refinancing and need to weigh the cost of points against the rate reduction on the new loan.
• You want to know the exact month when your cumulative savings will exceed the upfront cost of the points.

Common Mistakes

1. Ignoring the break-even timeline. Many buyers focus only on the lower rate without calculating how long it takes to recoup the upfront cost. If you sell or refinance before break-even, points cost you money.
2. Comparing points from different lenders incorrectly. One lender may offer 6.50% with no points, another 6.75% with a lender credit. Points move in both directions — negative points (lender credits) can offset closing costs at the price of a higher rate.
3. Forgetting the opportunity cost. $6,000 spent on 2 points invested at 7% grows to roughly $8,500 in 5 years. Compare the return from buying points against alternative uses of that cash.
4. Using the same rate reduction for all lenders. Some lenders offer only 0.125% per point, others 0.375%. Always confirm the exact reduction before running numbers.

Current Context for 2026

Mortgage rates in early 2026 have settled in the 6.50—7.25% range for 30-year fixed loans after the Federal Reserve held rates steady through late 2025. With rates at these levels, each 0.25% reduction from a point saves roughly $33 per $200,000 of loan balance monthly. That makes break-even on one point typically 55—65 months. Lenders in a competitive market are offering slightly more aggressive point pricing for high-credit borrowers (740+) with jumbo loans, where one point sometimes buys 0.375% of rate reduction rather than the standard 0.25%.

Tips

• Ask your lender for a no-points quote and a 1-point and 2-point quote simultaneously so you are comparing apples to apples from the same institution.
• If you plan to keep the loan fewer than 5 years, skip the points — the break-even rarely falls inside that window at current pricing.
• On loans above $600,000, the dollar savings per month are large enough that buying 1—2 points often makes sense if you plan to stay 7+ years.
• Tax deductibility of purchase-mortgage points (if you itemize) effectively reduces the true cost — on a $6,000 investment in a 22% bracket, the deduction is worth $1,320.
• Lender credits (negative points) are useful when cash is tight at closing; accept the higher rate only if you plan to refinance within 3 years.
• Run the calculator with both the standard 0.25% reduction and your lender’s actual reduction to see the real break-even before committing.
