How it works

You replace the 30-year loan with a new 15-year loan at 6.25%. The monthly payment jumps, but the loan is gone in half the time and total interest drops dramatically.

Assumptions

Illustrative 15-year refinance at 6.25% on the full current balance. No closing costs, points, or fees included — real refinances carry thousands in costs that change the math. Rate availability depends on credit, market conditions, and lender approval.
