Money in Indonesia.

Indonesia uses the Indonesian rupiah (IDR). Prices are sometimes quoted in US dollars, especially at luxury resorts and on some tours, but payments inside Indonesia are generally settled in rupiah. Once you arrive, you get rupiah from an ATM or a money changer.

The rupiah carries a lot of zeros, so paying Rp 50,000 or Rp 100,000 for everyday things is normal. A warung meal runs about Rp 25,000 to Rp 50,000, a coffee around Rp 30,000, and a short Grab or Gojek ride roughly Rp 20,000 to Rp 40,000. As a rough anchor, reckon on somewhere around Rp 15,000 to 16,000 to the US dollar, though the live rate above is what actually matters.

Card acceptance varies far more across Indonesia than most travelers expect. Jakarta, Surabaya, Bali and the other big hubs are very card-friendly, with Visa and Mastercard taken in hotels, malls, chains and larger restaurants. On smaller islands and in rural regions you'll find fewer international card terminals and fewer authorized money changers, so the further you get from the tourist trail, the more you'll lean on cash. American Express is accepted in far fewer places, so don't make it your only card.

You may run into a card surcharge, usually 2-3%, or a shop that claims to be "cash only" to avoid the processing fee. Bank Indonesia's payment rules actually prohibit merchants from passing card and QRIS costs on to you, although the rule isn't always enforced in practice, so you'll still meet it here and there. You're within your rights to decline the surcharge, though it's rarely worth a long argument, so keep some small cash for those places. Separately, your own bank may charge a foreign-transaction fee on every payment abroad, which is what the calculator below helps you avoid with the right card.

Contactless is worth using where you can. Wherever contactless card payments are accepted, Apple Pay and Google Pay usually work too, as long as they're linked to a Visa or Mastercard, and they're safer than the physical card because the terminal only ever sees a one-time token. It's the terminal that decides, not the wallet, so acceptance simply tracks wherever contactless is already in use.

You don't need a fat wad, but you do need some. Cards cover the big-ticket items; cash is for the day's small spending: warungs, street food, markets, drivers and parking. Rp 300,000 to Rp 500,000 on you is a reasonable amount, more if you're heading somewhere rural where ATMs thin out. When you do withdraw, take a larger amount in one go, since most machines charge a flat fee per withdrawal and fewer, bigger pulls spread that cost.

An ATM is usually the simplest way to get rupiah, but if you've brought cash from home or want to change a larger sum at once, a money changer can be worth it. Two things decide whether you get a fair deal: where you change, and how you handle the count.

QRIS is Indonesia's single national QR standard, and locals pay with it almost everywhere through apps like GoPay, OVO and DANA. For foreign visitors it's the most fiddly option to set up, and how well it works depends on where your bank or wallet is based.

Most visitors never need this, but if you're paying a villa deposit, sending money to family, or funding an Indonesian account as a long-stay or nomad, the rate you're quoted is rarely the rate you get. Most of the cost is hidden in the exchange rate rather than the visible fee, often a 3-6% markup you never see itemized.

The mid-market rate is the real mid-point you'd see on Google, and it's the benchmark a fair transfer should track. Specialist services like Wise and Instarem land within roughly 1% of it, and transfers to the main Indonesian banks, BCA, Mandiri, BNI and BRI, usually arrive quickly. A high-street bank wire can quietly cost 5-8% once the exchange-rate markup and correspondent-bank fees are counted, and it often takes days longer.
