A budget is considered balanced when the incomes are either the same or more than the outcomes.
Explanation:
A budget is a financial process where all the movements related to money have to be programmed, controlled and compared to make the ends meet. When this happens or even better when there is a profit you can say that you have a balanced budget, not having a balanced budget causes a deficit that will take a long time to be fixed.
