Should You Buy Mortgage Points?
Mortgage discount points let you pay an upfront fee to permanently lower your interest rate. One point costs 1% of your loan amount and typically reduces your rate by about 0.25 percentage points. Our free points calculator shows the upfront cost, your new monthly payment, the monthly savings, your break-even point, and your total net savings over the life of the loan.
How to Use the Points Calculator
- Loan amount: Enter the amount you are borrowing.
- Base rate: The interest rate your lender quoted without points.
- Points: How many points you are considering (1, 2, 1.5, etc.).
- Rate reduction: The rate drop per point your lender offers (typically 0.25%).
- Term: The length of your mortgage, 10 to 30 years.
How to Decide if Points Are Worth It
The key question is how long you will keep the mortgage. If you stay past the break-even point, buying points saves you money. If you sell or refinance before break-even, you lose. As a rough rule:
- Keeping the loan 5+ years: Points often pay off.
- Moving or refinancing within 5 years: Usually skip the points.
- Low cash at closing: Skip points; you can always refinance later if rates drop.
Points vs. Mortgage Buydown
Discount points permanently lower your rate for the entire loan term. A mortgage buydown only lowers your rate temporarily for the first few years, then the rate adjusts up to the note rate. Use our buydown calculator to compare the temporary buydown option, or use this calculator to evaluate paying points for a permanent rate reduction.
Frequently Asked Questions
What are mortgage discount points?
Discount points are fees you pay upfront to permanently lower your mortgage interest rate. One point equals 1% of the loan amount and typically reduces your rate by about 0.25 percentage points.
How much does one point cost?
One point costs 1% of your loan amount. On a $300,000 mortgage, one point costs $3,000. The cost is paid at closing and can sometimes be financed into the loan.
How much does one point lower my rate?
On average one point lowers your rate by about 0.25 percentage points, but the exact reduction varies by lender and market. Always ask your lender for their current points-to-rate buydown table.
What is the break-even point for buying points?
Your break-even point is the number of months it takes for your monthly savings to equal the upfront cost of the points. If you sell or refinance before break-even, you lose money. After break-even, you save every month you keep the loan.
Are mortgage points tax deductible?
Points paid on a purchase mortgage are usually deductible in the year you pay them. Points paid on a refinance are typically deducted over the life of the loan. Consult a tax professional for your situation.
Points vs. mortgage buydown — what is the difference?
Points permanently lower your rate for the life of the loan. A buydown (like a 2-1 or 3-2-1 buydown) only lowers your rate temporarily for the first few years, then the rate returns to the note rate.
Should I buy points if I plan to move soon?
Usually no. If you plan to sell or refinance before the break-even point, buying points will cost you more than you save. The calculator above shows your break-even so you can decide.
