FAQ
What should I compare first?
Start with the scheduled payment, total interest, and the interest saved from extra payments. Those three numbers usually show the trade-off clearly.
Can this help with refinancing decisions?
Yes. It can help you compare how payment size and total interest shift under different rate and term assumptions.
Why do extra payments matter so much early on?
Because reducing principal earlier leaves less balance to accrue interest over the rest of the loan.
