Perspective

Extra principal payments attack the front-loaded interest

Early in a loan, more of each payment is interest; extra principal early saves more total interest.

Refinance break-even is closing costs divided by monthly savings — a rough rule before tax and term effects.

FAQ

Common questions

How is monthly payment calculated?

Standard amortizing loan formula: payment = P × (r(1+r)^n) / ((1+r)^n − 1) where r is monthly rate and n is number of months.

What does break-even mean here?

Months until cumulative payment savings from the new loan equal one-time refinance costs. Shorter break-even is generally more attractive if you stay in the loan.
