About Mortgage Points

Mortgage points, also known as discount points, are fees paid directly to the lender at closing in exchange for a reduced interest rate. This is also called "buying down the rate," which can lower your monthly mortgage payments.

How Mortgage Points Work
  • Each point costs 1% of your mortgage amount. For example, one point on a $300,000 mortgage would cost $3,000.
  • The rate reduction varies by lender. Typically, one point reduces your interest rate by 0.25%, but this can vary.
  • Points are tax-deductible in the year you pay them if you itemize deductions (for primary residences).
When to Consider Buying Points
  • Long-term homeownership: If you plan to stay in your home beyond the breakeven point, points can save you money.
  • Fixed-rate mortgages: Points generally make more sense with fixed-rate loans than adjustable-rate mortgages.
  • Available cash: You need to have enough cash on hand to cover closing costs plus points.
Calculation Methodology

This calculator determines whether points are worthwhile by:

  1. Calculating your monthly payment with and without points
  2. Determining monthly savings from reduced interest
  3. Computing the breakeven point (when savings exceed the cost of points)
  4. Analyzing total savings over your expected time in the home
  5. Considering the time value of money and potential tax benefits

Understanding the Mortgage Points Calculator

The Mortgage Points Calculator is a practical tool that helps you evaluate whether paying mortgage points upfront can save you money over the life of your loan. By inputting key loan and personal details, you can see a side-by-side comparison of various mortgage point options and decide which one offers the best long-term value based on your homeownership plans.

Monthly Mortgage Payment Formula:
\( M = P \times \frac{r(1 + r)^n}{(1 + r)^n - 1} \)
Where:
- \( M \) = monthly payment
- \( P \) = loan amount (principal)
- \( r \) = monthly interest rate (annual rate ÷ 12)
- \( n \) = total number of payments (loan term in years × 12)

What Are Mortgage Points?

Mortgage points, also known as discount points, are optional fees you can pay at closing to reduce your interest rate. This is commonly referred to as "buying down the rate." Each point typically costs 1% of your total loan and can reduce your interest rate by about 0.25%, depending on the lender.

  • 1 point = 1% of loan amount
  • Lower interest rate = lower monthly payments
  • Can be tax-deductible for primary residences
