100 SGD to IDR: Convert Singapore Dollar to Indonesian Rupiah

You’re planning a trip to Indonesia and wondering how far your Singapore dollars will go. The answer depends on where you exchange your money and when you do it, with the current mid-market rate meaning 100 SGD is worth around 1.3 million Indonesian rupiah — but the amount you actually receive can vary by more than 100,000 IDR depending on the provider.

Current mid-market rate: 1 SGD = 13,178.01 IDR (XE) ·
100 SGD equals: 1,317,801.93 IDR (XE) ·
100,000 IDR equals: 7.59 SGD (based on XE mid-market rate)

How much is $100 SGD to rupiah?

Current mid-market rate for 100 SGD

The most recent mid-market rate from XE shows 1 SGD = 13,178.01 IDR, meaning 100 SGD equals 1,317,801.93 IDR. Wise reports a slightly different figure: 100 SGD = 1,280,480 IDR, reflecting the spread between providers.

How the rate is calculated

• Mid-market rate is the average of bid and ask prices in the interbank market, available to large institutions, not retail consumers.
• Retail providers add a spread (markup) to cover costs and profit. For example, BCA lists buy rates around 13,766.62 IDR and sell rates around 14,104.00 IDR per SGD, a spread of about 2.4%.
• DBS Indonesia shows similar spreads: 13,619.00 to 14,074.00 IDR.

The implication: the rate you see on a converter is not the rate you lock in. Always check the total cost including fees.

Comparison of provider rates

The spread between the best and worst quote for 100 SGD can exceed 130,000 IDR.

The pattern: online platforms like Wise and Revolut tend to offer rates closer to the mid-market, while cash-focused services like Ria and OFX quote higher rupiah amounts but often include fees that bring the effective rate down.

What is a good SGD to IDR exchange rate?

Factors that determine a good rate

A good rate is one that is within 1% of the true mid-market rate. Bank Indonesia publishes official reference rates that serve as a local benchmark. If the rate you’re offered is more than 3% away from the mid-market, you’re paying a premium.

Comparing provider rates: banks vs online platforms

• Banks (e.g., BCA, DBS Indonesia) typically add 2–3% to the mid-market rate.
• Online platforms like Wise and Revolut advertise spreads as low as 0.5% but may add transfer fees.
• Cash exchange counters at airports and tourist spots often have the worst rates, with spreads exceeding 10%.

The trade-off: online platforms offer better rates but require a bank account and internet access; cash counters are convenient but expensive.

When to convert to get the best rate

Exchange rates fluctuate intraday based on global market movements. Trading Economics tracks live SGD/IDR movements. Historically, the rate tends to be more stable during Asian trading hours. There is no guaranteed best time, but monitoring rates over a few days can help you lock in a favorable level.

For travelers, converting a day or two before departure online is often better than waiting until arrival.

What can you buy with 100000 Rupiah in Indonesia?

Cost of common items in Indonesia

100,000 IDR (about 7.59 SGD) has real purchasing power — it’s not pocket change. Here’s what that amount typically covers:

• A meal at a local warung (nasi goreng, soto ayam): 20,000–40,000 IDR
• A bottle of mineral water (600ml): 5,000 IDR
• A short taxi ride (within city center): 50,000 IDR
• Street food snacks (satay, martabak): 10,000–25,000 IDR
• One liter of premium gasoline: ~13,000 IDR

As a general rule, 100,000 IDR can cover a simple lunch and a taxi ride, or a full day of street food.

Regional price differences

Jakarta and Bali have higher tourist pricing than smaller Indonesian cities. OFX notes that the same rupiah budget buys less in prime tourist districts. In Yogyakarta or Malang, 100,000 IDR stretches further — you can get a full meal, transport, and still have change for a souvenir.

The implication: budgeting 100 SGD (about 1.3 million IDR) can cover 3–4 days of moderate travel outside luxury shopping, especially if you dine where locals eat.

Budgeting for daily expenses

For a budget traveler, daily expenses (three meals, local transport, and one attraction) range from 150,000 to 300,000 IDR. At 100 SGD, you have roughly 4–9 days of spending money depending on your habits. Convert carefully — every percentage point of spread eats into that budget.

Can I pay with SGD in Indonesia?

Where SGD is accepted

Singapore dollars are accepted in some tourist areas, particularly in Bintan and Bali at hotels, resorts, and certain shops. However, the exchange rate offered on the spot is usually poor — often 5–10% worse than the mid-market rate. Wise recommends converting to IDR beforehand for better value.

Exchange rate when paying with SGD

When you pay with SGD directly, the merchant sets the exchange rate. It’s almost always unfavorable. For example, if the mid-market rate is 13,178 IDR per SGD, a merchant might offer only 12,000 IDR per SGD — a 9% loss. You’re better off converting at a bank or online platform before you go.

Alternatives: local currency and card payments

• Withdraw IDR from ATMs using a debit card that offers fee-free withdrawals (common with digital banks).
• Use a credit card with no foreign transaction fees (e.g., some Singaporean credit cards).
• Mobile payment apps like GoPay and OVO are widely accepted in Indonesia; you can top them up with IDR.

The catch: ATMs in Indonesia charge a withdrawal fee (typically 10,000–50,000 IDR per transaction), so withdraw larger amounts to minimize fees.

How much is 100k rupiah in SGD?

Current conversion: 100,000 IDR to SGD

Using the mid-market rate from XE (1 SGD = 13,178.01 IDR), 100,000 IDR equals about 7.59 SGD. This is a useful mental benchmark: think of 100,000 IDR as roughly 7.50 SGD when budgeting.

Using the mid-market rate

The mid-market rate gives you the theoretical value. In practice, after bank spreads, 100,000 IDR might cost you 7.80 SGD (if you’re buying IDR) or give you 7.40 SGD (if you’re selling IDR). The difference is the spread you pay.

Reverse calculation for budgeting

If you’re planning a trip and want to know how many days 100 SGD will last, reverse the calculation: 100 SGD = 1,317,801.93 IDR at mid-market. Divide by your expected daily spend in IDR. For example, at 200,000 IDR per day, 100 SGD covers about 6.6 days.

Keep in mind that the actual IDR you get will be less due to spreads, so plan for 5–6 days per 100 SGD at a moderate budget.

Timeline: SGD/IDR rate snapshot

The most recent rate from XE (as of data collection) is 1 SGD = 13,178.01 IDR. Bank Indonesia’s JISDOR reference rate for USD/IDR was 17,944 IDR per USD on 17 July 2026, which indirectly affects SGD/IDR cross rates. Historical data from IDNFinancials shows a quote of 12,781.75 per SGD in April 2025, indicating that the rate has moved significantly over the past year.

The pattern: SGD/IDR has been volatile, with a range of roughly 12,300 to 14,100 over the past 12 months, according to data from CurrencyLive and Trading Economics.

Clarity: What’s confirmed vs. what’s unclear

For travelers and remitters, the choice is clear: use an online platform like Wise or Revolut to get within 1% of the mid-market rate, and avoid cash exchanges at airports or tourist spots. The difference of 100,000 IDR per 100 SGD is real money — enough for a meal or a taxi ride. Plan ahead, compare rates, and convert before you go to make every Singapore dollar count.
