What is the break-even point for mortgage points?

It is the time required for the lower-rate savings to recover the added upfront cost. This calculator shows both cash-flow and interest-and-fee break-even.

Are mortgage points tax deductible?

They may be under detailed federal rules. The calculator assumes no tax benefit; consult a qualified tax professional.

Q: Is one point always a quarter-percent rate reduction?

No. One point equals one percent of the loan amount, but the rate reduction depends on the lender, loan, borrower, and market.

AWLet’s make sure both quotes are solving the same loan.

Step 1 · Loan

What amount are you actually borrowing?

Use the loan amount—not the purchase price. Points are priced as a percentage of the mortgage principal.

Loan amount

Loan term

Compare the same term and loan type.

AWNow put the zero-point quote beside the lower-rate quote.

Step 2 · Written quotes

What did the lender actually offer?

Do not assume one point always lowers the rate by the same amount. Pricing changes by lender, loan, borrower, and market.

Rate without points

Rate with points

Discount points cost

One point equals 1% of the loan amount, but the rate reduction is whatever the lender quotes.

Other upfront fee difference

Only include lender-cost differences between these two otherwise matching quotes.

AWThe lower rate needs time to earn back the cash you spend today.

Step 3 · Your timeline

How long might you keep this mortgage?

Think about selling, refinancing, or paying off the loan—not only how long you may own the home.

Common questions

What I would want you to understand before paying points

Is one point always a quarter-percent rate reduction?

No. One point equals 1% of the loan amount, but the rate reduction depends on the lender, loan, borrower, and market. Enter the actual written rate.

Why are there two break-even figures?

Cash-flow break-even divides the added upfront cost by monthly payment savings. Interest-and-fee break-even also accounts for how the two loans pay principal differently.

What if I refinance or sell early?

If the mortgage ends before break-even, the lower rate may not have recovered its upfront cost. Your expected loan-hold period is central to the decision.

Are points tax deductible?

Sometimes, under detailed federal tax rules. This calculator assumes no tax benefit. Ask a qualified tax professional about your circumstances.

Is a temporary 2-1 buydown the same thing?

No. A temporary buydown subsidizes early payments without changing the note rate. Use the builder-incentive comparison and confirm the written buydown agreement with the lender.

Should I compare offers from different lenders this way?

First ask each lender for matching loan terms and points or credits. Then compare the complete Loan Estimates, including lender fees and five-year cost.

Sources and calculation notes

How this estimate is built

The calculator amortizes two fixed-rate loans with the same principal and term. It compares the points quote’s added upfront cost with monthly payment savings and cumulative interest savings. Taxes, insurance, HOA dues, mortgage insurance, and unrelated settlement charges are excluded because they are assumed equal.
