🏡 What Is a Points Buy Down?

A points buy down refers to paying an upfront fee to lower your mortgage interest rate. Each point typically costs 1% of your total loan amount and reduces your interest rate by about 0.25%, though the exact rate reduction can vary by lender.

For example:

  • If you take a $300,000 loan and pay for 1 point, it costs $3,000 (1% of $300,000).
  • In return, your lender may reduce your interest rate from 6% to 5.75%.

This reduction can lead to lower monthly mortgage payments and significant long-term savings — especially if you plan to stay in the home for several years.

🧮 How the Points Buy Down Calculator Works

The Points Buy Down Calculator helps you estimate how much money you can save by paying discount points upfront. It compares the cost of buying points with the savings achieved through a lower interest rate.

Key Inputs:

  1. Loan Amount:
    The total amount borrowed for your mortgage (e.g., $250,000).
  2. Interest Rate (Without Points):
    The standard mortgage rate offered by the lender before purchasing points.
  3. Interest Rate (With Points):
    The new, reduced rate after buying down points.
  4. Loan Term (Years):
    The number of years you’ll take to repay the loan (e.g., 15, 20, or 30 years).
  5. Points Purchased:
    The number of discount points you plan to buy.
  6. Point Cost (% of Loan):
    The cost per point, usually 1% of the loan amount.

Formula Used

The calculator uses standard amortization formulas to compute your monthly payments and total interest savings.

  1. Monthly Payment Formula: Monthly Payment = [P × r × (1 + r)ⁿ] / [(1 + r)ⁿ – 1] Where:
    • P = Loan Amount
    • r = Monthly Interest Rate (Annual Rate ÷ 12)
    • n = Total Number of Payments (Years × 12)
  2. Total Interest Paid: Total Interest = (Monthly Payment × n) – Loan Amount
  3. Total Cost of Points: Points Cost = Loan Amount × (Points ÷ 100)
  4. Break-Even Period: Break-Even (Months) = Points Cost ÷ Monthly Savings

This calculation shows how long it will take to recover the upfront cost of the points through lower monthly payments.

📘 Example Calculation

Let’s walk through an example to understand how this tool helps in decision-making.

Example:

  • Loan Amount: $300,000
  • Loan Term: 30 years
  • Interest Rate without Points: 6%
  • Interest Rate with 1 Point: 5.75%
  • Cost per Point: 1% of loan amount = $3,000

Step 1: Calculate Monthly Payments

  • Without Points:
    Monthly Payment = $1,798.65
  • With Points:
    Monthly Payment = $1,750.72

Step 2: Determine Monthly Savings

  • Monthly Savings = $1,798.65 – $1,750.72 = $47.93

Step 3: Calculate Break-Even Period

  • Break-Even = $3,000 ÷ $47.93 ≈ 62.6 months (around 5.2 years)

If you plan to stay in your home for more than 5 years, buying 1 point makes financial sense. Otherwise, you might not recoup your upfront investment.

🧠 Helpful Insights

  1. Long-Term Stay Benefits:
    The longer you stay in your home, the more beneficial it is to buy down points. It’s an investment that pays off over time.
  2. Refinancing Considerations:
    If you plan to refinance or sell your home soon, avoid paying for points, as you won’t stay long enough to benefit.
  3. Tax Deduction:
    Discount points may be tax-deductible in the year you pay them, depending on IRS rules and your specific loan situation. Always consult a tax advisor.
  4. Compare Multiple Lenders:
    Different lenders may offer varying rates for the same number of points, so it’s essential to shop around.
  5. Consider Partial Points:
    You don’t always have to buy full points. Even buying half a point can lower your rate slightly and cost less upfront.

✅ Benefits of Buying Down Mortgage Points

  • Reduced monthly mortgage payments
  • Lower total interest cost over the life of the loan
  • Potentially higher loan approval chances due to reduced debt-to-income ratio
  • Greater financial flexibility over time

However, remember that paying points increases your upfront costs — make sure you have enough savings for closing costs and down payment.

📊 When You Should Avoid Buying Points

  • If you plan to move or refinance within a few years
  • If the lender offers minimal rate reduction per point
  • When cash flow is tight during closing
  • If you prefer to invest that money elsewhere with higher returns
