See a year-by-year breakdown of principal versus interest for any fixed-rate loan.
Amortization is the process of paying off a loan through regular payments where, early on, most of each payment goes to interest - and over time, more and more goes to principal, even though the payment stays the same.
Monthly Payment = Principal × r ÷ (1 - (1 + r)^-n), with interest each month calculated as the remaining balance times the monthly rate.
On a 30-year, $250,000 loan at 6.5%, the first year is mostly interest, while the last year is almost entirely principal - a hallmark of how amortization works.
It's a table showing each loan payment broken into principal and interest, plus the remaining balance, from the first payment to full payoff.
Interest is charged on the remaining balance, which is highest at the start of the loan, so early payments are interest-heavy; the split shifts toward principal as the balance shrinks.
Yes — additional principal payments reduce the balance faster, which lowers total interest paid and shortens the loan term.
