📉 Mortgage Points Calculator
Should you buy mortgage discount points? Calculate your break-even period, monthly savings, and total interest saved. Compare the cost of points against the monthly payment reduction to make an informed decision.
What Is a Mortgage Points Calculator?
A mortgage points calculator helps you determine whether buying discount points on your mortgage is a smart financial decision. Mortgage points, also called discount points, are a form of prepaid interest that you pay upfront to permanently lower your mortgage interest rate.
Each point typically costs 1% of your loan amount and reduces your interest rate by about 0.25% (though the exact reduction varies by lender and market conditions). This calculator shows you the break-even point , how long it takes for your monthly savings to recover the upfront cost.
How Does the Mortgage Points Calculator Work?
The calculator performs the following steps:
- Calculates the cost of points , number of points × loan amount × 1%.
- Determines the reduced interest rate , base rate minus (points × rate reduction per point).
- Calculates the monthly payment for both scenarios (no points and with points) using the standard mortgage payment formula.
- Computes the monthly savings , payment without points minus payment with points.
- Calculates the break-even period , points cost divided by monthly savings.
- Projects net savings , monthly savings × months in home minus points cost.
- Generates a cumulative savings chart , showing how savings grow over time.

❓ Mortgage Points Calculator FAQ
What are mortgage points (discount points)?
Mortgage points are a form of prepaid interest that you pay upfront to lower your mortgage interest rate. One point costs 1% of your loan amount and typically reduces your rate by about 0.25%.
What is the break-even period for mortgage points?
The break-even period is the number of months it takes for your monthly savings to equal the upfront cost of the points. You can calculate it by dividing the points cost by the monthly payment savings.
Are mortgage points worth it?
Buying points is worth it if you plan to keep the loan past the break-even point. If you plan to move or refinance before the break-even point, paying points may not be worth it.
How much does one point reduce my interest rate?
Typically, 1 point reduces your interest rate by about 0.25%. However, the exact reduction varies by lender, loan program, and market conditions. You can adjust this in the calculator's advanced options.
How much does a mortgage point cost?
One point costs 1% of your loan amount. For example, on a $300,000 loan, one point costs $3,000.
Can I deduct mortgage points on my taxes?
For a purchase mortgage, points are generally fully deductible in the year paid if you itemize. For a refinance, points must generally be deducted over the life of the loan. Always consult a tax professional for your specific situation.
What if I plan to refinance or sell before the break-even point?
If you plan to refinance or sell before the break-even point, buying points is not worth it because you won't recoup the upfront cost through monthly savings. Use the "Years in Home" field in the calculator to see if points make sense for your timeline.
What is the difference between discount points and origination points?
Discount points are paid to lower your interest rate and are tax-deductible in some cases. Origination points are lender fees for processing the loan and are not deductible.
