Bank savings cards allow you to model cash savings into the client's bank accounts / cash reserve.
These funds will grow at the rate of return associated with your return assumption for Cash. Like taxable savings, bank savings will only occur in years that clients have adequate income inflows. Bank savings can be tracked within the Retirement > Cash Flows > Summary > Net Flows column.
The Bank savings option will only be available if your Planning Method setting is set to 'Modified Cash Flow Based', and your Cash Management Method setting is set to one of the 'Treat Bank Acct as Cash' options.
