The currency of Indonesia is the Indonesian rupiah, abbreviated IDR and written with the symbol Rp. As of 2026, one US dollar is worth roughly 15,800 rupiah, so prices are quoted in the tens of thousands. The rupiah is issued and managed by Bank Indonesia, the country's central bank, and is the only legal tender across the world's largest archipelago, used everywhere from Jakarta's shopping malls to the smallest village warung.
What the rupiah looks like
Because the rupiah trades at thousands to the dollar, Indonesia uses large face values. Banknotes currently circulate in denominations of Rp1,000, Rp2,000, Rp5,000, Rp10,000, Rp20,000, Rp50,000 and Rp100,000, with the red Rp100,000 note being the highest-value bill. To put that in perspective, the Rp100,000 note is worth only about US$6.30, which is why travelers quickly find their wallets stuffed with bills.
Coins are minted in smaller amounts, typically Rp100, Rp200, Rp500 and Rp1,000. In theory the rupiah is divided into 100 sen, but inflation rendered the sen worthless decades ago, so it survives only in accounting records and no longer appears in everyday cash. A Rp1 coin technically remains legal tender but has not been struck for many years.
A short history of the rupiah
The rupiah was introduced in 1946, in the turbulent years following Indonesia's 1945 declaration of independence, replacing the Netherlands Indies gulden left over from the Dutch colonial era. Establishing a single national currency was an act of nation-building, asserting sovereignty over a vast and newly unified country.
The currency's path has not always been smooth. During the economic turmoil of the 1960s, Indonesia experienced severe hyperinflation that wiped out much of the rupiah's value. The most dramatic blow came during the 1997–1998 Asian financial crisis, when the rupiah collapsed by more than 80 percent against the dollar, contributing to political upheaval. Since then, Bank Indonesia has rebuilt monetary credibility, and the rupiah has become a far more stable, managed currency.
Who appears on the banknotes
Indonesia redesigned its banknote family in 2016 and again refreshed the series in 2022, using the notes to celebrate national identity. Each bill honors a different independence-era hero, deliberately chosen from across the archipelago's many ethnic groups and regions:
- Rp100,000 (red): founding presidents Sukarno and Mohammad Hatta, who proclaimed independence.
- Rp50,000 (blue): statesman Djuanda Kartawidjaja.
- Rp20,000 (green): Sulawesi hero Sam Ratulangi.
- Rp10,000 (purple): Papuan leader Frans Kaisiepo.
- Rp5,000 (brown): religious and political figure Idham Chalid.
- Rp2,000 (grey): Jakarta-born nationalist Mohammad Hoesni Thamrin.
The reverse sides showcase traditional dances and natural landscapes, turning the currency into a small gallery of Indonesia's cultural diversity.
Using money as a traveler
Cash remains essential in much of Indonesia, particularly in Bali's local markets, on smaller islands, and in rural areas where card readers are uncommon. ATMs are plentiful in cities and tourist hubs but become scarce in remote regions, so it is wise to withdraw enough before heading off the beaten track. For currency exchange, bring clean, crisp US dollars, as exchange offices often reject torn or marked notes and pay lower rates for older bills.
Digital payments are growing fast in urban Indonesia. App-based wallets such as GoPay, OVO and DANA, along with the national QRIS standard, let you scan a code to pay for everything from ride-hailing to street food. Still, when quoting prices Indonesians frequently drop the last three zeros, saying "fifty" to mean Rp50,000 — a shorthand worth learning so you are not caught off guard.

Frequently Asked Questions
What is the symbol and code for the Indonesian rupiah?
The rupiah's international ISO currency code is IDR, and its symbol is Rp, usually written before the amount, as in Rp25,000.
Is the US dollar accepted in Indonesia?
The rupiah is the only legal tender, so day-to-day purchases must be made in rupiah. Some hotels, dive operators and tour companies in tourist areas may quote or accept US dollars, but you will generally get better value paying in local currency.
Why are Indonesian prices in such large numbers?
Because the rupiah trades at around 15,800 to one US dollar, even modest purchases run into the thousands or tens of thousands. Indonesia has periodically discussed a redenomination — cutting three zeros from the currency — to simplify transactions, though no such change has taken effect.
Who controls the Indonesian rupiah?
Bank Indonesia, the nation's central bank, issues the rupiah and sets monetary policy to keep prices stable and the currency's value steady across the archipelago.
