Point Cost Is Standardized; Rate Reduction Is Not
One discount point generally costs 1% of the loan amount. The interest-rate reduction associated with that point depends on the lender, product and market, so the calculator requires the actual before-and-after rates you are comparing.
The break-even estimate compares the upfront point cost with modeled payment savings. Selling, refinancing or otherwise ending the loan before break-even changes the outcome.
The important part of a points comparison is that the rate reduction must come from a real quote. One point often costs 1% of the loan amount, but there is no fixed rule that one point always lowers the rate by a particular number of percentage points. Enter the lender's actual no-points and points offers. The break-even period then tells you how long the monthly payment savings would need to continue before recovering the upfront point cost.
Frequently Asked Questions
Does one point always reduce the rate by 0.25 percentage points?
No. The cost of one point is generally 1% of the loan amount, but the rate reduction varies by lender, loan and market conditions.
What information should I get from the lender before using this calculator?
Get the actual interest rate and fees for each points option on the same loan amount and term. The calculator should compare real quotes, not assume a standard rate reduction per point.
