Loan Amortization Questions

What is an amortization schedule?

An amortization schedule is a payment-by-payment table that shows how much of each loan payment goes toward interest, how much goes toward principal, and how the remaining balance changes over time.

How is a monthly loan payment calculated?

For a fixed-rate loan, the monthly payment is based on the starting principal, the monthly interest rate, and the number of monthly payments in the term.

Why does principal increase over time?

Interest is calculated against the remaining balance. As the balance gets smaller, less interest is due each month, so more of the same payment can reduce principal.
