Mortgage points, also called discount points, are upfront fees you can pay to reduce your mortgage interest rate and monthly payments. One point costs 1% of the loan amount and typically reduces the rate by 0.25%.

Understanding Break-Even Points

To determine if buying points makes financial sense, calculate the break-even point:

  1. Calculate the total cost of points (1 point = 1% of loan amount)
  2. Calculate monthly payment savings from reduced rate
  3. Divide total cost by monthly savings to find break-even time in months

Example:

  • $300,000 loan at 7% interest
  • One point ($3,000) reduces rate to 6.75%
  • Monthly payment drops from $1,996 to $1,946 (saves $50/month)
  • Break-even: $3,000 ÷ $50 = 60 months (5 years)

When Buying Points Makes Sense:

  • You have extra cash after down payment and emergency fund
  • You plan to keep the loan longer than the break-even period
  • The monthly savings significantly impact your budget
  • Seller offers to pay for points (common in buyer's markets)

When to Skip Buying Points:

  • Planning to sell/refinance before break-even
  • Need cash for other purposes (repairs, renovations)
  • Monthly savings are minimal
  • Interest rates are expected to drop soon

Remember: Mortgage points are in addition to standard closing costs (2-6% of loan amount). Consider your complete financial picture and long-term plans before deciding to buy points.

Tax Benefit: Mortgage points may be tax-deductible, either in the year paid or over the loan's life, depending on your situation. Consult a tax professional for guidance.

Using a mortgage points calculator can help determine if buying points aligns with your financial goals by showing exact costs, savings, and break-even timelines for your specific situation.
