A bottle of Bintang, the local beer, can cost as little as 22,000 IDR (£1). Expect to pay more in an upmarket restaurant or hotel in popular areas of the country such as Bali or Jakarta.
A plate of nasi goreng from a local food cart or cafe can cost as little as 75p-£1. It can be every bit as delicious, if not better, than in some restaurants. For a sit-down meal somewhere midrange, expect to pay between 54,000 IDR (£3) to (127,000 IDR) £7.
A dorm bed or simple hut in a more remote area of Sumatra or Java will set you back £2-5. Expect to pay more in Bali and on the beautiful beaches of the Gili Islands, where reputable hostels can cost around £10 per person per night.
For a mid-range room for two people in a hotel or guesthouse in Bali, you'll pay upwards of 270,000 IDR (£15) per room. Fancier hotels can cost around £25-40 on the island, but if you're off the beaten track, for example in Sumatra or Sulawesi, you'll be able to find a bargain hotel room for next to nothing. Book in advance with STA Travel to bag the cheapest rates.
A taxi in the capital city of Jakarta costs around 8,000 IDR (less than 50p) per kilometre. A taxi ride from Jakarta's airport to the city centre will cost less than £10. Expect similar taxi or rickshaw fares in Bali, but haggle for much cheaper ones in other parts of the country!
Public transport in Indonesia comes in all kinds of wonderful shapes and sizes depending on the island you're on. Squeeze into a tiny bemo or angkot (minivan) for longer distances, or take a three-wheeler, similar to the tuktuks you'd find in other parts of Asia, for around 3000 IDR (20p) per kilometre. Boats and ferries between islands are super affordable - visit our Bali page to find out more about travelling between islands.
