A discretionary budget is an unspecified lump sum that states what the amount is for, what the maximum sum overall will be, and possibly specifies also a maximum sum per item.

Discretionary budgeting is useful when the expenditure for each item is small in terms of value. The administrative cost of dealing with each item far outweighs the control benefit available. However, control is maintained within the lump-sum budget.
