You are charged for the parts that are generated during multipart upload based on the storage class, actual size, and storage duration of the parts.
The storage class of the parts is the same as that of objects. However, the parts do not have a minimum billable size. If a part is less than 64 KB, it is still calculated based on the actual size.
For more information about the storage fees of parts, see Storage fees.
To avoid additional storage fees caused by parts, you can use one of the following methods to delete parts in a timely manner.
