Comparing Expense Ratios of Indonesian Index Funds: Complete Guide
When you’re choosing an index fund, the one number that most determines your long-term investment results isn’t past performance, isn’t the investment manager’s name, isn’t assets under management (AUM) — it’s the expense ratio.
This article breaks down the expense ratios of all major index fund products in Indonesia: what they include, why Indonesia is more expensive than the US, and the real impact of cost differences on your wealth over 10, 20, and 30 years.
What Is an Expense Ratio and What Does It Include?
Expense ratio is the total annual cost charged to investors for managing a mutual fund, expressed as a percentage of Net Asset Value (NAV). This cost isn’t billed separately — it’s directly deducted from NAV every day.
This means if a mutual fund generates 10% gross return in a year and its expense ratio is 1%, you receive 9% net — without you having to “pay” any explicit bill. The cost runs behind the scenes.
Components That Make Up an Expense Ratio
An expense ratio isn’t a single fee, but a combination of several components:
| Component | Typical Proportion | Description |
|---|---|---|
| Management fee | 60–70% of total | Compensation for the management team and IM infrastructure |
| Custodian fee | 15–25% of total | Bank that holds assets and handles settlement |
| Securities transaction costs | 5–10% of total | Broker commissions when IM buys/sells stocks in portfolio |
| Other operational costs | 5–10% of total | Audit, registrar, prospectus publication, etc. |
Concrete example: An index fund with 0.8% expense ratio per year on Rp 500 billion AUM means roughly Rp 4 billion per year goes to various parties — investment manager, custodian, broker, auditor.
What’s NOT Included in Expense Ratio
Don’t confuse expense ratio with other fees that platforms might charge:
- Subscription fee (purchase fee): Platforms like Bibit/Bareksa charge 0% for mutual funds (provided free). But some banks may charge 0.5–2%.
- Redemption fee (sell fee): Usually 0% on modern platforms. Some IMs charge a penalty if you sell within 30 days.
- Switching fee: Cost to move from one mutual fund to another within the same IM.

Comparison: Indonesia vs United States
Investors who read international investment literature are often surprised to see the very low expense ratios of US index funds. Here’s the comparison:
| Aspect | Indonesia | United States |
|---|---|---|
| Index fund expense ratio | 0.50–1.00% | 0.03–0.20% |
| Active fund expense ratio | 1.50–3.00% | 0.50–1.20% |
| Total mutual fund industry AUM | ~$30 trillion | |
| Number of mutual funds | ~2,000+ | ~10,000+ |
Why Are Indonesian Expense Ratios Higher?
1. Different economies of scale
Vanguard S&P 500 Index Fund (VFIAX) manages over $1 trillion. Bahana IDX30 manages around Rp 1–2 trillion (~$65–130 million). Fixed costs like team salaries, technology systems, and regulatory costs are divided across a much smaller asset base.
2. Higher custodian fees
Indonesia’s capital market infrastructure is still developing. Custodian fees in Indonesia (~0.15–0.25% per year) are proportionally more expensive than in the US (~0.01–0.05% per year).
3. Higher portfolio turnover
IDX30 and LQ45 rebalance every 6 months with potentially significant constituent changes. This generates higher transaction costs compared to the more stable S&P 500 index.
4. Less intense competition
In the US, the fee war between Vanguard, Fidelity, and BlackRock has pushed expense ratios close to zero. In Indonesia, competition among investment managers isn’t that fierce yet — though the trend is moving in the right direction.
5. Regulation and compliance
Costs to meet OJK (Financial Services Authority) requirements, prospectus publication, and periodic reports contribute to a higher cost structure.
The good news: Indonesian index fund expense ratios have dropped significantly in the last 5 years. From an average of ~1.2% in 2019 to ~0.7% in 2026. This trend will continue as the industry grows.
Expense Ratio Impact Calculator: 10, 20, 30 Years
This is the part that often surprises investors. Let’s look at the real impact of expense ratio differences on your final wealth.
Assumptions: Lump sum investment of Rp 100 million, 10% gross market return per year (historical IHSG/Jakarta Composite Index long-term returns are around 10–12% per year nominal).
Impact of Expense Ratio Differences on Rp 100 Million
| Expense Ratio | Value After 10 Years | Value After 20 Years | Value After 30 Years |
|---|---|---|---|
| 0.50% (Pinnacle) | Rp 237 million | Rp 562 million | Rp 1,333 million |
| 0.75% (Avrist) | Rp 230 million | Rp 530 million | Rp 1,221 million |
| 1.00% (BNP SRI-KEHATI) | Rp 224 million | Rp 501 million | Rp 1,120 million |
| 2.00% (Average active fund) | Rp 206 million | Rp 426 million | Rp 878 million |
Formula: FV = PV × (1 + r - expense_ratio)^n
Final Wealth Difference
| Comparison | 10-Year Difference | 20-Year Difference | 30-Year Difference |
|---|---|---|---|
| 0.50% vs 1.00% | Rp 13 million | Rp 61 million | Rp 213 million |
| 0.50% vs 2.00% | Rp 31 million | Rp 136 million | Rp 455 million |
| 1.00% vs 2.00% | Rp 18 million | Rp 75 million | Rp 242 million |
Reading this table: Choosing a 0.50% index fund over a 2.00% active fund could result in Rp 455 million more from an initial Rp 100 million investment over 30 years. That’s not a small difference — that’s a life-changing difference.
Simulation with Regular Investment (DCA)
More realistic: many investors make regular monthly investments. Here’s a simulation of DCA Rp 1 million per month over 20 years:
| Expense Ratio | Total Deposited | Final Value | Profit |
|---|---|---|---|
| 0.50% | Rp 240 million | Rp 747 million | Rp 507 million |
| 1.00% | Rp 240 million | Rp 674 million | Rp 434 million |
| 2.00% | Rp 240 million | Rp 549 million | Rp 309 million |
Assumptions: 10%/year gross return, monthly investment at month-end
The expense ratio difference of 0.50% vs 1.00% alone (just 0.5%) results in a Rp 73 million difference over 20 years from Rp 1 million monthly contributions. Meanwhile, the difference versus a 2% active fund reaches Rp 198 million.
How to Read Expense Ratio in a Fund Fact Sheet
Every investment manager is required to publish a Fund Fact Sheet (FFS) every month. Here’s how to read the expense ratio in it:
- Download the FFS from the investment manager’s website or platform (Bibit/Bareksa has a “Prospectus” button for each product)
- Look for the “Fees” section or “Operating Expense Ratio” — usually on pages 2–3
- Pay attention to two figures: (a) expense ratio or total expense ratio — this is the relevant number, (b) management fee — this is just the largest component
- Compare with similar products tracking the same index
Red flag: If the FFS doesn’t clearly state the expense ratio, or only lists the management fee without total expense ratio — ask customer service. Transparency is your right as an investor.
When a Higher Expense Ratio Might Still Be Acceptable
For index funds tracking the same index, lower expense ratio always wins. There’s no argument for paying more.
But there are situations where a higher expense ratio might be worth considering:
1. Different Index
SRI-KEHATI with ~1% expense ratio provides exposure to 25 high-quality ESG stocks with strict selection criteria. If you care about sustainable investing, this premium might be worthwhile — but first compare with global ESG index alternatives if available.
2. Active Fund with Consistent Track Record
Very rarely, but there are active investment managers who consistently beat the index for more than 10 years after fees. If you find this and believe it can continue, a 2% expense ratio might be worthwhile if they outperform 3–4% above the index consistently.
The problem: You can’t know in advance which ones will win. See active vs passive funds for more complete data.
3. Access to Special Asset Classes
Some mutual funds provide access to assets that are difficult to access directly (e.g., diversified corporate bonds, property via DIRE/REITs, foreign assets). In these cases, the value of accessing these assets might exceed the additional cost.
Practical Strategy: Choosing Index Funds Based on Cost
Step 1: Determine Your Desired Index
First choose the benchmark index: IDX30, LQ45, or SRI-KEHATI? For most passive investors, IDX30 is the most practical choice — most products available, more competitive expense ratios.
Step 2: Compare Expense Ratios for the Same Index
After choosing an index, compare all products tracking that index. Pick the one with the lowest expense ratio — that’s it.
Step 3: Verify Tracking Error
A low expense ratio is useless if the fund doesn’t track the index accurately. Check tracking error in the FFS — ideally below 0.5% per year. A fund with high tracking error means its portfolio doesn’t reflect the index well.
Step 4: Pay Attention to Liquidity
Check AUM and daily transaction volume. For mutual funds (not ETFs), liquidity isn’t a big issue because IMs are required to accept purchases and redemptions. But AUM that’s too small (<Rp 50 billion) could indicate fund closure risk.
Step 5: Choose a Platform with 0% Transaction Fees
Use Bibit or Bareksa which offer 0% subscription fee and 0% redemption fee for mutual funds. Don’t buy mutual funds through banks that charge 0.5–2% transaction fees — that effectively adds to your expense ratio.
Common Question: Can Expense Ratios Change?
Yes, they can. Investment managers can change expense ratios with notice to investors. In practice:
- Expense ratio changes are relatively rare, but can happen
- Usually IMs send notifications via email or platform if there are significant changes
- The global trend is declining expense ratios as competition increases
Recommendation: Check the FFS at least once a year to make sure your chosen product’s expense ratio hasn’t quietly increased. This is also good for periodic portfolio performance evaluation.
