About the Loan Amortization Schedule Calculator
An amortization schedule breaks every loan payment into a principal portion and an interest portion. This calculator finds the loan's status — balance, principal paid, and interest paid — as of any specific payment number.
Formula: Each month, Interest = Balance × Monthly Rate, Principal = Payment − Interest, and Balance decreases by the Principal portion.
Early in a loan's life, the interest portion of each payment is much larger than the principal portion — that balance gradually flips as the loan matures.
