I need an algoritm for estimating the size of my Access database. I've found one for SQL Server but none for Access.

The databases I have are stored on a monthly basis and the user can specify which data channels (they are all doubles) and how often each they should be stored. From that I can calculate the number of records that will be stored in the table. I then need to calculate the total database size to make a decision if this should be allowed or not.
