Schedule

Amortisation & balloon

What is the payment, and what is still owed on the maturity date?

A full commercial schedule with three clocks: an interest-only period, the amortisation the payment is calculated on, and the term at which the balloon comes due. Month and year views, with a running total.

Every default here is an illustrative figure chosen to be plausible. Nothing on this page is a rate sheet, a quote or an offer, and no licence or NMLS number exists to attach to it.

Balance to maturity

Illustrative

The flat stretch at the start is the interest-only period, where nothing is repaid. The drop at the right-hand edge is not repayment — it is the balloon falling due in one payment on the maturity date.

Where each payment goes

Principal against interest, year by year. On a commercial loan the interest bar stays taller than the principal bar for the whole term, which is exactly why the balloon is so large.

Assumptions on this page

  • Payments are made monthly in arrears at a fixed rate. Interest accrues on the outstanding balance, not on the original amount.
  • During the interest-only period no principal is repaid, so the balance is flat and the balloon is larger.
  • Extra principal is applied after the interest-only period ends and reduces the balloon rather than the payment.
  • No escrow, reserve deposit, servicing fee or prepayment charge is included.
  • Illustrative arithmetic on a demonstration site. Not a quote, not an amortisation schedule from a servicer.
