About the Mortgage Points Calculator

Mortgage points are upfront charges expressed as a percentage of the loan amount. Discount points may be paid to obtain a lower mortgage interest rate, creating a tradeoff between higher closing cost and lower future payments.

Whether points are worthwhile depends mainly on the rate reduction, loan size and how long the borrower expects to keep the loan. Selling or refinancing early can prevent the monthly savings from recovering the upfront cost.

How to Use the Mortgage Points Calculator

  1. Enter the mortgage loan amount.
  2. Enter the number of points and cost per point if the calculator uses standard percentage points.
  3. Enter the payment savings or compare the quoted rates with and without points.
  4. Calculate upfront point cost and break-even time.

How the Calculation Works

One mortgage point commonly costs 1% of the loan amount, so point cost = loan amount × points/100.

If paying points reduces the monthly payment by a known amount, simple break-even months = upfront point cost ÷ monthly payment savings. A more complete comparison can consider time value of money and tax treatment separately.

Worked example

Mortgage Points Calculator Worked Example

1 point on a $300,000 mortgage saving $75 per month

Point cost = $300,000×1% = $3,000. Simple break-even = $3,000÷$75 = 40 months.

Result guide

Understanding Your Mortgage Points Calculator Result

A 40-month simple break-even means the borrower must keep the lower-payment loan for roughly that long before cumulative payment savings equal the upfront point cost, ignoring time value and tax effects.

Before you rely on the answer

Assumptions and Limitations

  • Point pricing and rate quotes come from the actual lender scenario.
  • Monthly savings reflect otherwise comparable loan terms.
  • Taxes, investment opportunity cost and refinance probability are outside simple break-even.

Practical tip

Using This Result in Practice

Compare lender quotes on the same day and with the same loan term, lock period and fees. A point comparison is not meaningful if other loan costs are changing at the same time.
