There is no record limit in an Access table, only a file size limit of 1MB up to Access '97, and 2MB for all other versions.

Having said that, Access does slow down considerably after 1M records, and most developers I know would consider another back-end such as MySQL or SQL Server if they hit that mark.  The 1M figure will vary depending on developer preference, business availability, number of concurrent users, and other things.

Oops, GB instead of MB.

Here's what I get from Help, Answer Wizard - Specifications.

Microsoft Access database table specifications
Attribute Maximum
Number of characters in a table name 64
Number of characters in a field name 64
Number of fields in a table 255
Number of open tables 2048. The actual number may be less because of tables open internally by Microsoft Access.
Table size 1 gigabyte
Number of characters in a Text field 255
Number of characters in a Memo field 65,535 when entering data through the user interface;
1 gigabyte when entering data programmatically.

Are you trying to calculate max number of records for a table within a database?  
Add max size of each field in bytes for max recordsize in bytes.
Divide into 1 billion or 2 billion, and you will get a rough estimate.
