What is an Amortization Schedule?

An amortization schedule shows how each payment is split between principal and interest over the life of the loan. Early payments are mostly interest; later payments are mostly principal. This calculator generates a full schedule and lets you add optional extra monthly payments to see how much interest and time you can save.

Monthly Payment = P × [r(1+r)^n] ÷ [(1+r)^n − 1]

P = principal, r = monthly rate, n = number of payments

Interest for each period = balance × monthly rate. Principal = payment − interest. New balance = previous balance − principal.

Các khái niệm chính

Hiệu trưởng

The amount you borrowed. Each payment reduces the principal until the balance is zero.

Quan tâm

The cost of borrowing. Early in the loan, most of each payment is interest; over time, more goes to principal.

Thanh toán thêm

Any amount paid beyond the required payment goes directly to principal, reducing the balance faster and saving interest.

Monthly payment

The fixed amount you pay each month. It stays the same; the split between principal and interest changes over time.

Payoff date

The date the loan balance reaches zero. With extra payments, this date is earlier than the original term.

Total interest

The sum of all interest payments over the life of the loan. Extra payments reduce this amount.

Schedule table

Each row shows payment number, date, payment amount, principal, interest, and remaining balance. Use Monthly or Yearly view.

  • This is for estimation only. Actual schedules may vary with rounding or lender policies.

  • Confirm with your lender that extra payments are applied to principal and do not incur penalties.
