By default, the Phoenix budget produces an overall cashflow balance, not itemising specifically which accounts hold the balance. You can ask Phoenix to track the balance on many accounts simultaneously. This will then allow Phoenix to calculate the interest to be paid or received on each account, and takes your budget one step closer to being a complete financial plan.
There are two types of accounts that can be incorporated into your budget. Cashflow accounts are the reconciled accounts (except loan accounts) used in the accounting system. Funding and Asset accounts are for loans and investments.
You can define many accounts for a set of financial data. Phoenix Budgets is capable of maintaining projected bank balances for any or all of these bank accounts simultaneously, in any one budget.
