Example Scenarios

Example 1: 30-Year Fixed, $300,000 Loan
Scenario Rate Monthly Payment Points Cost
No Points 6.50% $1,897 $0
1 Point 6.25% $1,847 $3,000
2 Points 6.00% $1,799 $6,000

With 1 point, you save $50/month. Break-even is 60 months (5 years). If you stay longer than 5 years, buying the point saves money.

Example 2: Short Stay vs Long Stay

On a $400,000 loan at 7% with 1 point (cost $4,000, rate drops to 6.75%):

  • Stay 3 years: Save $65/month = $2,340 total. Net loss: -$1,660. Points not worth it.
  • Stay 5 years: Save $65/month = $3,900 total. Net loss: -$100. Roughly break-even.
  • Stay 10 years: Save $65/month = $7,800 total. Net savings: +$3,800. Points worth it.

Key insight: The longer you stay, the more valuable points become.

Example 3: Small Loan vs Large Loan

The impact of points scales with loan size:

  • $150,000 loan, 1 point: Cost $1,500. Monthly savings ~$25. Break-even: 60 months.
  • $600,000 loan, 1 point: Cost $6,000. Monthly savings ~$100. Break-even: 60 months.

The break-even period is similar, but the absolute savings are much larger on bigger loans, making points more impactful for higher loan amounts.

Standard Amortization Formula
M = P ร— [r(1 + r)^n] / [(1 + r)^n โˆ’ 1]

M = Monthly payment

P = Principal loan amount

r = Monthly interest rate (annual rate รท 12)

n = Total number of monthly payments (years ร— 12)

Points Cost Formula
Points Cost = Loan Amount ร— (Points / 100)

1 point = 1% of the loan amount

Example: $300,000 loan ร— 1% = $3,000 cost

Break-Even Formula
Break-Even Months = Points Cost / Monthly Savings

Monthly Savings = Payment(no points) โˆ’ Payment(with points)

If break-even < planned stay: Points are worth it

If break-even > planned stay: Points are not worth it

Total Savings Formula
Total Savings = (Monthly Savings ร— 12 ร— Stay Years) โˆ’ Points Cost

Includes both the upfront cost and ongoing savings

Positive value means points save you money overall

When Should You Buy Mortgage Points?

  • Plan to stay long-term: If you'll keep the mortgage 5+ years, points often make sense.
  • Extra cash available: If you have funds for closing costs, points can be a good investment.
  • Tax-deductible: Mortgage points are typically tax-deductible as mortgage interest (consult a tax professional).
  • Lower monthly payment: If reducing monthly cash flow is a priority, points help.

When Should You Skip Points?

  • Short stay: If you plan to sell or refinance within 3-5 years, you won't recoup the cost.
  • Tight on closing costs: Use your cash for a larger down payment instead.
  • Low-rate environment: When rates are already historically low, the savings may not justify the cost.
  • First-time buyers: Extra cash is often better used for down payment or emergency fund.

What Are Mortgage Points?

Mortgage points (also called discount points) are a form of prepaid interest that allows you to reduce your mortgage interest rate. One point typically costs 1% of your loan amount and reduces your interest rate by approximately 0.25% (though this varies by lender and market conditions).

When you buy points, you pay an upfront fee at closing in exchange for a lower monthly payment over the life of the loan. This is essentially "buying down" your interest rate. The key question is whether the long-term savings outweigh the upfront cost โ€” and that depends primarily on how long you plan to keep the mortgage.

โœ… When Points Make Sense

You plan to stay in the home for many years (5+), you have extra cash for closing, and you want lower monthly payments. Points are essentially a guaranteed return on investment โ€” the savings are predictable and tax-deductible.

โŒ When to Skip Points

You plan to sell or refinance within a few years, you're tight on closing costs, or interest rates are already very low. In these cases, the upfront cost is unlikely to be recouped through monthly savings.

How Points Affect Your Mortgage Rate

The relationship between points and rate reduction isn't always linear. While a common rule of thumb is that 1 point = 0.25% rate reduction, the actual reduction depends on your lender, loan program, and current market conditions. Some lenders may offer different pricing structures.

Points Purchased Approximate Rate Reduction Example Rate (from 6.50%) Cost on $300k Loan
0 0.00% 6.50% $0
0.5 ~0.125% 6.375% $1,500
1.0 ~0.25% 6.25% $3,000
1.5 ~0.375% 6.125% $4,500
2.0 ~0.50% 6.00% $6,000

Actual rate reductions vary by lender. Always get a personalized quote from your mortgage lender.

Frequently Asked Questions

What are mortgage discount points?
Mortgage discount points are a form of prepaid interest that you pay upfront at closing in exchange for a lower interest rate on your mortgage. One point typically costs 1% of your loan amount and reduces your rate by about 0.25%. For example, on a $300,000 loan, one point costs $3,000 and might reduce your rate from 6.5% to 6.25%.
How do I calculate the break-even point for mortgage points?
The break-even point is calculated by dividing the cost of the points by your monthly savings. For example, if points cost $3,000 and save you $50 per month, your break-even is 60 months (5 years). If you plan to stay in the home longer than the break-even period, buying points saves you money. If you'll move or refinance sooner, you'll lose money on the points.
Are mortgage points tax deductible?
Yes, mortgage points are generally tax-deductible as mortgage interest. If you buy points on a loan to purchase your primary residence, you can typically deduct the full amount in the year you pay them. For refinancing, points must be deducted ratably over the life of the loan. Always consult with a tax professional for your specific situation, as tax laws can change and individual circumstances vary.
How much does 1 point reduce the interest rate?
While the standard rule of thumb is that 1 point = 0.25% rate reduction, the actual amount varies by lender, loan program, and market conditions. Some lenders may offer a 0.20% reduction per point, while others might offer 0.30%. Always ask your lender for a rate sheet showing the exact rate reduction per point for your specific loan scenario.
Should I buy points on a refinance?
Buying points on a refinance follows the same logic as a purchase: calculate the break-even period. However, with refinancing, the break-even should also account for your closing costs. If the break-even period for the combined costs (points + other refinance fees) is shorter than how long you plan to keep the new loan, points may be worth it. Many homeowners refinance when rates drop and then sell within a few years, so points often don't make sense on a refinance unless you plan to stay long-term.
Can I negotiate mortgage points with my lender?
Yes, mortgage points are often negotiable. Lenders can offer different combinations of rates and points โ€” sometimes called "rate/point combinations" or "pricing options." You might also see lender credits, where the lender offers to cover some of your closing costs in exchange for a higher rate (the opposite of buying points). Always compare multiple loan estimates from different lenders and ask about all available rate/point combinations to find the best deal for your situation.
