Do not store calculations in a table. You can do the calculations in a
VIEW, in the application or in computed columns (a proprietary
shorthand) for a VIEW. This will save you disk space of course. It
will also run faster, since reading from a disk is very slow compared
to math done in main storage. But the real benefit is data integrity,
which your approach will destroy.
