How Mortgage Points Work
Discount points are upfront fees paid at closing to get a lower mortgage interest rate.
- 1 point usually equals 1% of the loan amount. On a $400,000 mortgage, 1 point typically costs $4,000.
- Main benefit: a lower interest rate can reduce your monthly payment and possibly your total interest cost.
- Main tradeoff: you pay more money up front in exchange for savings that build slowly over time.
- Best fit: points usually make more sense when you expect to keep the loan long enough to pass the break-even point.
- Higher risk case: if you sell, refinance, or pay off the loan early, the points may never fully pay for themselves.
Whether buying points is worthwhile depends on your rate reduction, upfront cost, closing costs, whether costs are financed into the loan, and most importantly your expected holding period.
How to Know if Buying Points Makes Sense
The break-even point is the number of months it takes for monthly savings from a lower interest rate to equal the cost of the points paid. A shorter break-even period may make discount points more attractive, especially if you expect to keep the loan for many years.
This calculator compares:
- Loan amount with and without financed points or closing costs
- Monthly mortgage payment differences
- Total interest paid over the loan term
- Balance remaining at break-even
- Total long-term loan cost
- Monthly and annual amortization schedules
Because actual lender pricing, APR, taxes, insurance, escrow requirements, and loan program rules can differ, you should compare official Loan Estimates from lenders before making a final borrowing decision.
Important Notes
This calculator is for educational and estimation purposes only. Results are based on the values you enter and assume a fixed-rate mortgage with scheduled monthly payments over the full loan term. The calculation does not automatically include property taxes, homeowners insurance, mortgage insurance, HOA fees, prepaid items, lender-specific underwriting adjustments, or tax consequences.
If discount points or closing costs are included in the loan balance, the total financed amount increases, which may affect both your monthly payment and total interest paid. Actual mortgage terms and point pricing vary by lender, credit profile, market conditions, and loan type.

FAQs
What is a mortgage point?
A mortgage point usually equals 1% of the loan amount and is paid upfront to lower the interest rate on a mortgage.
How do I calculate the break-even point on mortgage points?
The break-even point is generally calculated by dividing the upfront cost of the discount points by the monthly payment savings created by the lower rate.
Is buying mortgage points worth it?
Do closing costs count as mortgage points?
No. Closing costs and discount points are related loan expenses, but they are not the same. Discount points are optional fees used to reduce the interest rate, while closing costs include other charges associated with the loan transaction.
Does this calculator include taxes and insurance?
No. This calculator focuses on principal, interest, discount points, and closing costs. Property taxes, insurance, escrow, and other housing costs are not automatically included unless you add them separately elsewhere.
