Buying Down the Mortgage Rate

When buying a home, the mortgage interest rate dictates your long-term costs. If market rates are high, your mortgage payments will be expensive. However, you can lower your rate at closing by purchasing "discount points." One discount point usually costs 1% of your loan amount and reduces your rate by roughly 0.25%. But are points actually worth the upfront cash?

This points calculator simulates your monthly and lifetime savings. Enter your loan amount, interest rate, and points to find your break-even point.

Quick Answer

Purchasing mortgage discount points is financially smart if you plan to keep your home loan longer than the break-even period (typically 5 to 7 years). If you plan to move or refinance sooner, buying points will likely cost you more than you save.

Key Takeaways

• Upfront pre-paid interest: Points cost 1% of your mortgage loan amount at closing.
• Rate reduction: Each full point purchased lowers your rate by roughly 0.25%.
• Calculate break-even: Divide the upfront cost of points by your monthly payment savings.
• Time is the deciding factor: Keep the loan past break-even to make points profitable.
• Refinance risks: Prepayment or early refinancing cancels out the benefit of points.
• Tax-deductible buy-down: Upfront points are often tax-deductible for primary residences.
• Opportunity cost: Weigh the upfront cost of points against investing that cash in the stock market.

What Is Mortgage Points Calculator?

The Mortgage Points Calculator is a refinancing and buy-down optimization tool. It compares a standard mortgage rate with a discounted rate to find your exact break-even point.

How Does It Work?

Our tool calculates your monthly payment under both your standard rate and discounted rate. It then divides the upfront cost of the points by your monthly savings to find your break-even timeline in years.

Understanding The Formula

Let $L$ be your loan amount and $P$ be the number of points purchased. The upfront cost is: $Cost_{\text{points}} = L \times \frac{P}{100}$

Monthly savings: $Savings_m = Payment_{\text{standard}} - Payment_{\text{discounted}}$

Our tool computes your break-even horizon in years as: $Years_{\text{breakeven}} = \frac{Cost_{\text{points}}}{Savings_m \times 12}$

Step-by-Step: How To Use The Calculator

1. Enter your expected mortgage loan amount and original base rate.
2. Select the number of discount points you plan to buy.
3. Review the upfront cost and your new discounted payment.
4. Check your break-even timeline to see if buying points is worth it.

Real-Life Examples

• Individual: Clara takes a $200k mortgage. Buying 1 point costs $2,000 upfront, saving her $33/mo and breaking even in 5 years.
• Family: The Gomezes take a $400k loan. Buying 1.5 points costs $6,000 upfront, saving them $105/mo and breaking even in 4.7 years.
• High-income professional: Tyler buys 2 points on an $800k loan for $16,000. He saves $275/mo, breaking even in 4.8 years.

Why This Tool Matters

Our points calculator provides a clear, objective look at upfront costs and long-term savings. It helps you make the right choice for your financial timeline.

Common Mistakes People Make

• Buying points when you plan to sell or move within 3 to 4 years.
• Draining your emergency savings to buy points, leaving you vulnerable to repair costs.
• Automatically assuming points are a good deal without calculating your break-even point.

Expert Tips To Improve Results

• Ask your seller to pay for your discount points as part of your closing negotiations.
• Remember that points only make sense if you stay in your home loan past the break-even years.

Factors That Affect The Results

Your loan size, original interest rate, points purchased, and the time you keep your mortgage determine your exact savings.
