Some notes about Rupiahs
The official currency of Indonesia is the Rupiah (abbreviated as Rp). It's derived from the Hindustani word rupiyaa that means wrought silver.
Coins come in denominations of 25, 50, 100, 200, 500 and 1000 Rupiahs. However because of the small amount of low value coins in circulation, you are more likely to be given sweets than coins for your change.
Notes are in denominations of Rp100,000, 50,000, 20,000, 10,000, 5,000, 2,000 and 1,000. The easiest way to distinguish them is by size. The designs and the pale pastel colours are confusingly similar. What's worse, the smaller bills in particular are likely to be a little tatty.
As a rough guide you'll need 10,000 and 20,000 Rupiah notes for taxis, and 50,000 and 100,000 Rupiah denominations when you go shopping.

How to make your Indonesian money go further
How far your money goes in Indonesia depends to an extent where you are. Indonesia is a vast nation made up of thousands of islands, and some are cheaper than others.
For example Java has a reputation for being more expensive than Sumatra. That said, wherever you are it's worth bartering. Indonesians won't be offended - they expect people to ask to pay less, so prices are high to allow room to manoeuvre. Walking away is a good tactic - you'll almost invariably be offered a lower price to change your mind.
The buses are magic
When you travel there is a massive difference in cost between local and tourist transport. A public bus can get you to the same destination for about a 50th of the price of a private car.
Don't buy your ticket until you get on the bus though - a tout will take a big cut. Just find the bus that goes to your destination and wait until you're approached by an attendant. If you think you're still being overcharged, "mahal" is the Indonesian word for expensive.
Look for the small family owned restaurants, or "warungs" if you want real value for money. The food - and the prices - are for locals.
Is the exchange rate for Rupiahs going up or down?
Is now the time to buy your Indonesian currency, or might you be better off waiting until the rate improves? Our Historical Exchange Rate tool shows you if there's a trend you might want to take advantage of.
Are you flying over with children?
If you're flying to Indonesia you could be spending a long time in the air - it's around 15 hours for a direct flight to Bali or Jakarta. That could feel like an eternity if you're bringing your children with you - for you, and for them.
