Rainy day fund

Reserved amount of money used when regular income is disrupted

A rainy day or rainy day fund is a reserved amount of money to be used in times when regular income is disrupted or decreased in order for typical operations to continue. In the United States, the term is usually used to apply to the funds maintained by most U.S. states to help deal with budget shortfalls in years where revenues do not match expenditures. This is critical to the operations of most states, which do not permit their governments to take on debt, meaning that services would have to be cut in the absence of reserve funds.
