Why does software maintenance cost so much?

Software maintenance cost is derived from the changes made to software after it has been delivered to the end user. Software does not “wear out” but it will become less useful as it gets older, plus there WILL always be issues within the software itself. Software maintenance costs will typically form 75% of TCO.
