Living costs in Indonesia are cheap. The lowest prices in the country are found in Solo, a city popular with students and international travellers.    Yearly rental prices are around two to three million rupiahs (£100 to £150), and the Solo Trans transport system costs about 3,000 to 15,000 - £0.15 to £0.75.   Jakarta is the most expensive city in Indonesia, and a meal out costs around 15,000 rupiahs (£0.75) per person, which is considered pricey for local produce.   Imported goods are much more expensive than Indonesian products since the archipelago's nature means that sea and air shipping adds a chunk to consumer prices, so it's best to avoid foreign items if you can find a local equivalent.   It's also essential to be conscious of inflation. Changes in value mean that living in Indonesia is now much more costly than as recently as five or ten years ago, but it is still cheap by UK standards.
