Master the Rupiah Millionaire Mindset

The Indonesian Rupiah (IDR) features a lot of zeros, which can easily lead to costly mathematical mistakes for first-time visitors. A quick mental shortcut to convert the currency is to drop the last three zeros; for example, 100,000 IDR becomes 100. From there, you can easily convert it to your home currency. Always double-check the notes you hand over, as the blue 50,000 IDR note and the blue-grey 2,000 IDR note can look deceptively similar in low light.

While credit cards are widely accepted in high-end establishments in Bali and Jakarta, cash remains king throughout the rest of Indonesia. Always carry small denominations (10,000, 20,000, and 50,000 IDR) for local markets, street food stalls (warungs), and public toilets. When withdrawing cash, use ATMs located inside secure bank branches to minimize the risk of card skimming, and always notify your bank of your travel plans beforehand.
