A redemption schedule is the part of the terms of a bond or other debt security that sets out how the principal will be repaid. For a bullet bond it is a single entry: the whole amount at par on the maturity date. For an amortising bond or a sinking fund issue it lists a series of dates with the amount or percentage of principal due on each. Where the issuer or the holder has an option to redeem early, the dates and prices are given in the call schedule or put schedule.
The schedule determines the security's cash flows and average life, so it is needed to calculate yield and duration, and it is stored as reference data by custodians, paying agents and pricing systems. For securitisation notes the schedule is often only expected, since actual repayments depend on collections from the underlying assets. See bond redemption.
