Mortgage Points Calculator
Convert mortgage points from a percentage of loan amount to dollars, compare fixed principal-and-interest payments at the base and points-adjusted rates, and calculate a simple break-even month from upfront cost divided by monthly payment savings.

How to use Mortgage Points Calculator
- Enter loan amount, rate without points, rate with points, points percentage, and mortgage term from the same lender scenario.
- Compare the upfront points cost with monthly principal-and-interest savings and the resulting simple break-even time.
- Use the exact loan estimate to review other fee changes, tax treatment, cash constraints, and how long the loan is likely to be retained.
Calculator guide
Understanding Mortgage Points Calculator
Discount points exchange cash paid at closing for a lower mortgage rate. The key question is not merely whether the payment falls, but whether the loan will remain outstanding long enough for cumulative payment savings to recover the upfront points cost.
Calculation method
How the calculation works
Convert points to an upfront dollar cost, compare fixed-rate payments, and divide the cost by monthly savings to estimate break-even time. Convert points to an upfront dollar cost, compare fixed-rate payments, and divide the cost by monthly savings to estimate break-even time.
Worked situations
Practical examples
- On a $400,000 mortgage, 1.5 points equals an upfront cost of $6,000 before considering any other lender fees.
- Enter the quoted rate without points and the paired rate offered with the exact entered points amount.
- Compare the break-even horizon with expected sale, refinance, or early-payoff timing.
Better inputs
Useful tips
- Use quotes obtained at the same time for the same product, term, lock period, occupancy, and borrower profile.
- Distinguish discount points that reduce rate from origination charges that may also be described in points.
- Evaluate the alternative use of upfront cash and any applicable tax treatment separately.
Before relying on the result
Limitations and common mistakes
- The model assumes the only difference between offers is upfront points and fixed interest rate.
- Other closing charges, lender credits, taxes, opportunity cost, financed points, mortgage insurance, prepayment, sale, refinance, and amortization-based interest savings are excluded.
- The simple break-even uses payment savings rather than a discounted cash-flow or after-tax analysis.
Reference
Key terms
- Mortgage point
- One percent of the mortgage amount when used as a pricing unit.
- Base rate
- Entered mortgage rate for the comparison offer without discount points.
- Points-adjusted rate
- Entered lower rate paired with the stated points charge.
- Simple break-even
- Upfront points cost divided by monthly principal-and-interest savings.
Important note

Frequently asked questions
Does one point always reduce the rate by the same amount?
No. Pricing varies by lender, market, product, lock period, borrower, and date; enter the paired quoted rates.
What happens if the loan is refinanced before break-even?
Cumulative payment savings will generally not have recovered the entered points cost.
Should financed points be treated differently?
Yes. Adding points to principal increases the loan and interest; this page assumes the points amount is an upfront cost.
Are points tax deductible?
Tax treatment depends on purpose, timing, jurisdiction, and current rules and is not calculated here.
