Monthly budget
Your monthly budget compares the income you expect this month with the amount you have assigned across categories and funds.
Under your expected income
Some income is still unassigned. Add that amount to the categories or funds that matter next, or update your expected income if the estimate is too high.
Over your expected income
Your category and fund plans add up to more than you expect to earn. Reduce one or more planned amounts, or update your expected income if the estimate is too low.
A zero difference means the month’s plan is in sync: all expected income has been given a job without planning more than you expect to receive.
