Inspect annual and monthly balance schedules, track the exact breakdown of principal versus interest over time, and calculate time and interest saved by making extra monthly or lump-sum payments.
Mathematical Formula
Monthly interest = Remaining Balance × (Annual Rate / 12); Monthly Principal = Total Payment - Monthly Interest.
Frequently Asked Questions
How do extra payments shorten my mortgage term?
Extra payments reduce the outstanding principal balance immediately. Because interest in subsequent months is calculated on a lower balance, more of each regular monthly payment goes toward principal, accelerating payoff exponentially.
