Inputs

Mortgage principal used to estimate points cost and rate savings.
Discount points purchased as a percentage of the mortgage amount.
Estimated annual interest-rate reduction created by the purchased points.
Planned time you expect to keep the mortgage before refinancing or selling.

Outputs

Estimated cash paid upfront to buy the selected mortgage points.
Approximate yearly interest savings from the selected rate reduction.
Months needed for yearly savings to recover the upfront points cost.

Assumptions

Interest savings are modeled from a simple annual rate reduction on the current loan amount.
The loan balance is treated as stable for a quick breakeven estimate.

Tips

Compare breakeven months with how long you realistically expect to keep the mortgage.
If you might refinance soon, a lower upfront-cost scenario is often worth testing first.
