An amortization schedule breaks down every loan payment into its principal and interest components over the full loan term. It shows exactly how much of each payment reduces the balance versus paying interest.

Формула

Payment = P × [r(1+r)ⁿ] / [(1+r)ⁿ − 1]

In month 1 only $248.88 of $1,498.88 reduces the principal balance
