Referring to expenses or costs that were not planned or included in a budget.
The company faced several unbudgeted expenses this quarter due to unexpected repairs.
Unbudgeted → It is formed from "un-" (meaning not) and "budget" (from Old French *bougette*, meaning a small bag or purse, which evolved to mean a financial plan). The word "unbudgeted" means not planned or accounted for in a financial budget.
Think of 'not' ('un-') being applied to a 'financial plan' ('budget') — that's why unbudgeted refers to expenses that are not planned.
