Cash rounding or Swedish rounding (New Zealand English) occurs when the minimum unit of account is smaller than the lowest physical denomination of currency. The amount payable for a cash transaction is rounded to the nearest multiple of the minimum currency unit available, whereas transactions paid in other ways are not rounded (for example electronic funds transfer such as with payment cards, or negotiable instruments such as cheques). Cash rounding typically occurs when low-denomination coins are removed from circulation owing to inflation. Cash rounding may be a compulsory legal requirement if such coins are no longer legal tender, or a voluntary practice where they remain in circulation but are scarce or impractical.

Cash rounding () was introduced in Sweden in 1972 when 1 and 2 öre coins were withdrawn from circulation, and has continued to be applied at incremental levels as smaller denomination coins have been withdrawn. The current level of cash rounding in Sweden is to the closest whole krona, after the 50 öre coin was withdrawn in 2010. The Reserve Bank of New Zealand used the name "Swedish rounding" in 1990 when withdrawing their 1- and 2-cent coins. In Canada, cash rounding to the nearest nickel (5 cents) due to the elimination of the penny in 2013 is also called penny rounding. In the United States, businesses are permitted, but not required, to round to the nearest nickel when pennies are unavailable.

When small-value coins are withdrawn, an alternative to the implementation of cash rounding is instead to increase the minimum unit of account to the smallest remaining currency unit and to round all prices and bank accounts to this value. Whereas cash rounding is an ongoing process, this alternative is a one-time conversion. It was done, for example, when the British farthing was withdrawn in 1960.

Practice Rounding is applied to the total of a bill, not to the line items on the bill. Typically, the total is rounded to the nearest multiple of the smallest denomination, which may be higher or lower than the unrounded total. Where the unrounded total is an equal distance from two multiples, practice varies: merchants may be required or encouraged to round down rather than up, giving the benefit to the buyer. An equal distance is possible when the rounding interval is an even number.

The introduction of cash rounding is typically accompanied by publicity campaigns for awareness among both consumers and implementing merchants; smaller campaigns will accompany the extension of an existing rounding system to a higher rounding interval.

Rounding with 0.05 or 5 intervals Country Dates Notes Albania One lek coins were last produced in 2013. Although they continue to circulate and are legal tender, cash transactions may be rounded to the nearest multiple of five lekë. Argentina Always rounded down.
