The expense ratio (Total Expense Ratio / TER) is the annual fee a mutual fund charges to manage your money. It is never billed separately — it is silently deducted from your fund's NAV every single day, making it invisible to most investors.
The Basic Formula
─────────────────────
Total Assets Under Mgmt
If a fund has ₹500 Cr AUM and spends ₹5 Cr/year, its ER = 1.0%. This covers fund manager fees, admin, marketing, and compliance costs.
How It Erodes Returns
With ER (net): FV = PV × (1 + r − ER)ⁿ
A 1% ER on a 12% fund = 11% net. Over 20 years, that 1% gap can erase 15–20% of your final portfolio value.
Daily NAV Deduction
The fund never sends a bill. Each day's NAV is published after deducting 1/365th of the annual TER.
Example: Fund earned 0.040% today, TER = 1%/yr → NAV actually grew by only 0.040% − 0.0027% = 0.0373%. Tiny daily, massive over time.
Two Calculation Methods
Precise: (1+r)^(1/12)−1. Exact. 12% stays 12% p.a.
Industry (r÷12): Used by Groww, Zerodha, ET Money, AMFI. Overstates annual return by ~0.5–1% because (1+0.12/12)^12 = 12.68%, not 12%.
📋 SEBI Maximum TER Limits (India)
SEBI mandates decreasing TER slabs as a fund's AUM grows — larger funds must charge less.
| Category | AUM Slab | Max TER |
|---|---|---|
| Equity Funds | ≤ ₹500 Cr | 2.25% |
| Equity Funds | ₹500–₹750 Cr | 2.00% |
| Equity Funds | ₹750–₹2,000 Cr | 1.75% |

What Is a Mutual Fund Expense Ratio? (And Why It Matters More Than You Think)
Every mutual fund charges a small annual fee to manage your money. This fee is called the Expense Ratio — or more formally, the Total Expense Ratio (TER). You never see it as a line item on your statement. You never get a bill for it. Instead, it quietly gets subtracted from your fund’s daily NAV (Net Asset Value), every single day, 365 days a year.
That invisibility is exactly what makes it dangerous.
Even a 1% expense ratio on a ₹10 Lakh investment growing at 12% for 20 years can cost you over ₹12–15 Lakhs in lost compounding. That’s not a rounding error — that’s a car, a down payment, or years of retirement income silently consumed by fees.
This calculator helps you see exactly how much your fund’s TER is costing you — in real rupees, over your actual investment horizon.
How to Use This Calculator
How to Use This Calculator — Step by Step
It takes under two minutes. Here is exactly what each field means:
Step 1 — Choose Your Calculation Mode
Precise Mode (recommended): Uses the mathematically exact formula (1+r)^(1/12)−1 to convert your annual return to a monthly rate. A 12% annual rate compounds at exactly 12% per year. Results will be slightly lower than what Groww or ET Money shows — but this is the correct answer.
Industry Standard Mode: Uses the simplified formula r÷12 — the same method used by AMFI, Groww, Zerodha, and ET Money. Because of this formula, a 12% annual rate actually compounds at 12.68% per year. This mode lets you match what other tools show — so you can compare results side by side.
|
Why do Groww and ET Money show higher numbers? It’s not a bug — it’s a calculation convention. When tools use r÷12 as the monthly rate, a 12% annual return silently compounds to 12.68% effective annual return. Over a 20-year SIP, this 0.68% overstatement adds up to a meaningful gap. Our Precise Mode corrects for this. The comparison card in your results shows both numbers side-by-side so you can see the difference for your exact inputs. |
Step 2 — Enter Your Investment Amount
Initial Capital (Lump Sum): Any one-time amount you have already invested or plan to invest. Enter 0 if you are only doing SIP.
Recurring SIP Investment: The amount you invest regularly. Choose Monthly, Quarterly, or Yearly to match your actual SIP schedule. Enter 0 if you are only investing a lump sum.
Step 3 — Set Your Parameters
Duration: How many years you plan to stay invested. Use the slider — drag right for longer horizons. The impact of expense ratio grows dramatically with time.
Expected Annual Growth: Your fund’s expected rate of return before the expense ratio is applied. For large-cap equity funds, 10–14% is a common assumption. This calculator works with gross returns and deducts the ER separately.
Expense Ratio (TER): Check your fund’s factsheet or AMC website for the exact TER. Direct plans typically charge 0.5–1% less than Regular plans. The slider goes up to 5%, and a warning appears if you go above SEBI’s equity fund cap of 2.25%.
Step 4 — (Optional) Enable Step-Up SIP
Toggle on Step-Up SIP if you plan to increase your SIP amount every year — for example, by 10% annually to match salary increments. This more accurately reflects how most long-term SIP investors actually invest.
Step 5 — Click Calculate Impact
Your results appear instantly. You will see four headline numbers, a Precise vs Industry comparison, a full breakdown with donut chart, and a comparison table showing how different expense ratios would affect your specific portfolio.
Understanding Your Results
What Each Number in Your Results Means
Total Invested
This is the sum of all money you personally put in — your lump sum plus all your SIP contributions over the entire investment period. It does not include any returns. This is your actual out-of-pocket capital.
Value Without ER (Gross Value)
This is what your portfolio would be worth if the fund charged zero expense ratio — the theoretical maximum. It represents your growth using only the expected annual return you entered. In reality, no fund is free, so this is a ceiling, not a realistic target.
Lost to Expenses
This is the most important number. It shows the total rupee amount permanently lost to the fund’s annual TER over your investment period. It is the difference between your gross portfolio value and your actual net portfolio value. Notice: this number is not just the TER percentage of your final value — it is larger, because returns you could have earned on that money were also lost.
Final Value (After ER)
This is your actual projected portfolio value after the expense ratio has been deducted continuously over your investment period. The CAGR shown below it is your net compound annual growth rate — the real return you actually earned after fees.
The Precise vs Industry Standard Comparison Card
This card is unique to this calculator. It runs both the Precise formula and the Industry Standard formula on your exact inputs simultaneously, so you can see the gap between them. The ‘Overstatement Gap’ shown in orange is how much more Groww, ET Money, or AMFI calculators would show compared to the mathematically exact result — not because they are wrong by intention, but because they use a simpler formula that was standardized across the industry.
For most investors doing a 10-year monthly SIP, this gap is typically ₹1–3 Lakhs on a ₹10L investment. Over 20–30 years, it can exceed ₹10–15 Lakhs.
The ER Impact Comparison Table
This table runs the same calculation for eight different common expense ratios (0%, 0.25%, 0.5%, 0.75%, 1%, 1.5%, 2%, 2.5%) using your exact portfolio inputs, and highlights your fund in gold. The ‘Loss vs 0%’ column shows how much each TER level costs you specifically — not in abstract percentages, but in real rupees based on your numbers.
Use this table to answer the question: is the extra cost of an actively managed fund justified compared to a low-cost index fund?
Expense Ratio — Plain Language Explainer
What Is an Expense Ratio in Mutual Funds?
The expense ratio is the annual percentage fee that a mutual fund charges to cover the cost of running the fund. It includes the fund manager’s salary, administrative expenses, marketing costs, compliance fees, and other operational expenses.
The formula is simple:
|
Expense Ratio = Annual Operating Costs ÷ Total Assets Under Management × 100
Example: Fund AUM = ₹500 Cr | Annual costs = ₹5 Cr | Expense Ratio = 1.0% |
How the Expense Ratio Is Deducted — Daily NAV Method
The expense ratio is not charged as a lump sum at the end of the year. Instead, the fund deducts 1/365th of the annual TER from its daily NAV. This means the NAV you see published every day is already after the day’s tiny fee deduction.
Here is a worked example:
- Your fund earned 0.040% today on its portfolio (gross return).
- The fund’s TER is 1.0% per year, which is 0.0027% per day.
- The NAV published today reflects growth of 0.040% − 0.0027% = 0.0373% (net).
- Each day this 0.0027% is small. Over 365 days for 20 years, it becomes enormous.
How Expense Ratio Affects Your Returns Over Time
The impact of the expense ratio is not linear — it compounds. Every rupee the fund takes as fee is a rupee that can no longer earn returns for you in future years. This is the compounding cost of fees.
The math looks like this:
|
Without expense ratio: FV = PV × (1 + r)^n With expense ratio: FV = PV × (1 + r − ER)^n |
A 1% expense ratio on a fund earning 12% per year means your effective return is 11%. That single percentage point, compounded over 20 years, costs far more than 1% of your money.

Precise Mode vs Industry Standard — Full Explanation
Why Does This Calculator Give Different Numbers Than Groww or ET Money?
If you have ever compared this calculator’s results to what Groww, ET Money, or AMFI’s calculator shows, you may have noticed that those tools show slightly higher final values. This is not a mistake on either side — it is a difference in calculation methodology.
Here is the technical reason, explained simply:
The Industry Standard Method (r÷12)
Most Indian investment apps and calculators — including the AMFI SIP calculator — use a shortcut when converting an annual return to a monthly rate. They simply divide the annual rate by 12:
|
Monthly rate = r ÷ 12
For 12% annual: Monthly rate = 12% ÷ 12 = 1.0% per month
Actual effective annual rate = (1.01)^12 − 1 = 12.68% ← not 12%! |
This means every calculator using r÷12 is silently assuming your fund earns 12.68% per year when you entered 12%. That 0.68% overstatement is small for a short investment but compounds significantly over 15–30 years.
The Precise Method — Mathematically Exact
|
Monthly rate = (1 + r)^(1/12) − 1
For 12% annual: Monthly rate = (1.12)^(1/12) − 1 = 0.9489% per month
Effective annual rate = (1.009489)^12 − 1 = 12.00% ← exactly correct |
This is the formula used in professional financial modelling, actuarial calculations, and by financial regulators globally. It ensures that the annual return you enter is the actual annual return the calculator uses.

SEBI Maximum TER Limits — What They Mean for You
How SEBI Regulates Mutual Fund Expense Ratios in India
SEBI (Securities and Exchange Board of India) sets mandatory maximum limits on what any mutual fund can charge as TER. These limits are structured on a sliding scale — the larger the fund’s AUM (Assets Under Management), the lower the maximum TER allowed. The logic is that larger funds have economies of scale and should pass savings on to investors.

|
Important: These are maximums, not norms A fund charging 2.25% TER is technically SEBI-compliant, but that doesn’t mean you should accept it. Many actively managed large-cap funds charge 1.5–1.8%. Index funds from major AMCs charge as low as 0.05–0.20%. Always compare what the fund charges against what category peers charge — not just the SEBI maximum. |
Direct Plan vs Regular Plan — The Expense Ratio Gap
What Is the Difference Between Direct and Regular Mutual Fund Plans?
When you invest in a mutual fund, you have two options for every scheme: the Direct plan and the Regular plan. Both invest in exactly the same portfolio of stocks or bonds. The only difference is the expense ratio.
Regular plan: The AMC pays a distribution commission to the intermediary (broker, app, bank, or distributor) who brought you to the fund. This commission is embedded in the TER, making Regular plans typically 0.5–1.0% more expensive per year than Direct plans.
Direct plan: You invest directly with the AMC — no intermediary, no commission. Lower TER, higher NAV, better long-term returns. Available through Groww Direct, Zerodha Coin, Kuvera, MFCentral, or directly on the AMC website.
|
Real-Money Impact of 0.75% Direct vs Regular Gap ₹10,000 monthly SIP, 12% gross return, 20 years: • Regular Plan (1.5% TER): ~₹86.5 Lakhs • Direct Plan (0.75% TER): ~₹93.2 Lakhs • Difference: ~₹6.7 Lakhs — lost purely to commission, not to fund underperformance. |

|
Q: What is expense ratio in mutual funds? A: The expense ratio is the annual percentage fee that a mutual fund charges to cover its operating costs — including fund manager fees, admin, and marketing. It is expressed as a percentage of the fund’s average AUM and is deducted daily from the NAV rather than billed separately. A 1% expense ratio on a ₹10L investment means ₹10,000 is deducted annually. |
|
Q: How does expense ratio affect SIP returns? A: The expense ratio reduces the effective annual return of your SIP. If a fund grows at 12% but charges 1% TER, your net return is approximately 11%. Because SIP returns compound over years, even a 1% annual drag can reduce your final corpus by 10–20% over a 20-year period. The longer you stay invested, the larger the absolute rupee impact. |
|
Q: What is a good expense ratio for a mutual fund in India? A: For index funds and ETFs: 0.05% – 0.20% is excellent. For actively managed large-cap funds: 0.50% – 1.00% is reasonable. For mid or small-cap active funds: up to 1.50% is acceptable if returns justify it. Anything above 2.0% for an equity fund is high by Indian standards, and you should verify whether the fund’s returns justify the cost. |
|
Q: What is the difference between Precise Mode and Industry Standard Mode? A: Precise Mode uses (1+r)^(1/12)−1 to calculate the exact monthly equivalent of an annual return. Industry Standard Mode uses r÷12 — a simpler approximation used by most Indian calculators including AMFI, Groww, and ET Money. The r÷12 method silently overstates the annual compounding rate (12% becomes 12.68%), leading to higher projected values that aren’t mathematically accurate. |
|
Q: What is SEBI’s maximum TER limit for equity mutual funds? A: SEBI mandates that equity mutual funds charge no more than 2.25% TER for funds with AUM up to ₹500 Cr. As AUM grows, the maximum allowed TER decreases: 1.75% for ₹750 Cr–₹2,000 Cr, down to 1.05% for funds above ₹50,000 Cr. Index funds and ETFs are capped at 1.00% regardless of AUM. These limits apply to Direct plans. |
|
Q: Is a direct plan always better than a regular plan? A: In terms of expense ratio, yes — Direct plans always have a lower TER than Regular plans of the same fund because they don’t include distributor commission. Over the long term, this translates to meaningfully higher returns. The only reason to use a Regular plan is if you genuinely need ongoing personalised financial advisory services from a SEBI-registered advisor who is worth that commission. |
|
Q: How is expense ratio deducted from mutual fund NAV? A: The expense ratio is not charged as a lump sum. Instead, the fund deducts 1/365th of the annual TER from the NAV every day. This means the NAV you see published is already net of that day’s fee. For a 1% TER fund, approximately 0.00274% is deducted from NAV daily. This daily deduction makes the fee invisible in account statements, which is why many investors underestimate its long-term impact. |
|
Q: What is Step-Up SIP and how does it affect expense ratio calculations? A: A Step-Up SIP (also called a top-up SIP) is an arrangement where your SIP amount automatically increases each year — typically by 5–15% annually to match income growth. This calculator’s Step-Up SIP feature accounts for this increasing contribution when projecting both gross and net portfolio value. The expense ratio impact scales up with higher contributions, so the absolute rupee cost of TER is higher in Step-Up SIP scenarios. |
|
Q: Can I use this calculator for debt funds and hybrid funds? A: Yes. The calculator works for any fund type — equity, debt, hybrid, index, or liquid funds — as long as you enter the correct expected return and TER. For debt funds, the expected return will typically be 5–8% instead of 10–14% for equity. Debt fund TERs are also lower (0.10–0.50% for direct plans), so the absolute rupee loss to fees will be smaller but still worth calculating. |
What Every Investor Should Remember About Expense Ratios
- The expense ratio is deducted daily from your fund’s NAV — you never see it as a bill, which makes it easy to ignore and dangerous to overlook.
- Even a 1% TER can cost 10–20% of your final corpus over a 20-year investment horizon, purely due to the compounding effect of fees.
- Most Indian investment calculators (Groww, ET Money, AMFI) use the r÷12 formula which overstates returns by approximately 0.5–1% annually. Our Precise Mode corrects for this.
- Direct plans always have a lower TER than Regular plans of the same fund. Over 20 years, this difference can amount to ₹6–15 Lakhs on a typical SIP.
- SEBI mandates maximum TER limits — check that your fund is not charging close to the maximum without a strong performance track record to justify it.
- For index funds and ETFs, expense ratios below 0.20% are available. If your active fund cannot consistently outperform a comparable index after fees, a lower-cost index fund may be the better choice.
- The ER Impact Comparison table in this calculator lets you quantify exactly how much you would save by switching from a 1.5% regular plan fund to a 0.5% direct plan index fund — in your own rupees, not abstract statistics.
