Example

Let's assume you have two accounts in your YNAB budget: "Checking" and "Savings". The statement period is set to end on the 3rd of each month. After running the code, you may see output similar to the following:

Account: Checking
Average Daily Balance: $1,234.56

Account: Savings
Average Daily Balance: $5,678.90

This output indicates that the average daily balance for the "Checking" account within the statement period is $1,234.56, and the average daily balance for the "Savings" account is $5,678.90.
