Grenada's official currency is the Eastern Caribbean dollar (EC$) , although the US dollar is widely accepted at hotels, restaurants and shops, and by car rental and taxi companies. The EC dollar is divided into 100 cents. Bills come in denominations of 5, 10, 20, 50 and 100 EC dollars; coins in 1, 2, 5, 10 and 25 cents. At the time of writing, the rate of exchange was roughly EC$2.70 to US$1.

Credit cards and major travellers' cheques are accepted at most hotels, restaurants and larger shops. Prices such as bus fares and admission fees have been quoted in EC$; all other prices are given in US$.
