If you borrow against mutual funds, the interest cost depends on the amount you actually use, the lender's rate, how interest is calculated, and how quickly you repay. Unlike a normal EMI loan, some Loan Against Mutual Funds (LAMF) facilities work more like an overdraft, where interest can be charged on the amount outstanding rather than the full approved limit.
For example, if you use ₹3 lakh for a full year at a hypothetical 11% annual rate, simple annual interest on a constant ₹3 lakh outstanding would be ₹33,000. Your actual cost can be different because lenders may calculate interest daily, change the rate, charge fees, or allow you to reduce the outstanding balance during the year.
How is interest calculated on a Loan Against Mutual Funds?
The basic idea is:
Interest = outstanding amount × annual interest rate × time
If a lender charges 11% per year and you keep ₹3 lakh outstanding for exactly one year:
₹3,00,000 × 11% = ₹33,000
This is a simplified illustration. If you repay ₹1 lakh after six months, the interest for the remaining period would be calculated on the lower outstanding amount under the lender's applicable method.
That is why the amount actually drawn and the time it remains outstanding matter as much as the sanctioned limit.
Is LAMF interest charged on the full approved limit?
Not necessarily.
Some LAMF products may operate as an overdraft or credit facility. In such a structure, you may receive an approved limit against your pledged investments but pay interest based on the amount actually utilised.
For example, suppose:
- Approved limit: ₹4 lakh
- Amount actually used: ₹2 lakh
- Illustrative interest rate: 11% p.a.
If ₹2 lakh remains outstanding for one year, simple illustrative interest would be:
₹2,00,000 × 11% = ₹22,000
Do not assume this structure applies to every lender. Check the sanction terms for the exact interest calculation, billing cycle and repayment method.
Does LAMF use EMI or interest-only repayment?
It depends on the product.
A lender may structure the facility as an overdraft, demand loan or another form of secured credit. Your agreement should specify:
- Interest rate
- Whether the rate is fixed or floating
- How interest is calculated
- Minimum repayment, if any
- Due dates
- Processing and other charges
- What happens if the outstanding amount is not repaid
- What happens if the value of the pledged mutual funds falls
If the facility allows part-prepayment, reducing the outstanding amount earlier can reduce future interest.
₹3 lakh LAMF example
Consider a hypothetical facility where you use ₹3 lakh at 11% per year.
If ₹3 lakh remains outstanding for 12 months
Approximate simple interest:
₹3,00,000 × 11% = ₹33,000
If you repay ₹1 lakh after six months
For illustration, assume the first ₹3 lakh remains outstanding for six months and ₹2 lakh remains outstanding for the next six months.
First six months:
₹3,00,000 × 11% × 6/12 = ₹16,500
Next six months:
₹2,00,000 × 11% × 6/12 = ₹11,000
Illustrative total interest:
₹27,500
The example shows why reducing the outstanding balance sooner can matter. Actual lender calculations may use daily outstanding balances and their own contractual methodology.
What other costs should you check?
Interest is only one part of the borrowing cost.
Before accepting an LAMF facility, check:
- Processing fee
- Applicable taxes on fees
- Documentation or pledge-related charges
- Account or renewal charges, if any
- Prepayment or closure conditions
- Minimum interest or other product-specific charges
- Charges connected with a margin shortfall, if applicable
Ask the lender for the complete schedule of charges rather than comparing headline interest rates alone.
What happens if your mutual fund NAV falls?
Your mutual fund units remain exposed to market movements even though they are pledged as collateral.
Suppose your pledged portfolio is worth ₹5 lakh when the loan is taken. If the NAV falls and the collateral value declines materially, the lender may require additional collateral or repayment depending on its applicable LTV and agreement.
This is one reason an LAMF should not be treated as risk-free borrowing.
MLE already explains this in detail in its guide to margin calls when your mutual fund NAV falls.
Can you redeem mutual funds after taking an LAMF?
Generally, pledged or lien-marked units cannot be freely redeemed or switched until the lender's obligations are settled and the pledge/lien is released.
SEBI-hosted scheme documentation explains that pledged units cannot be redeemed until the lender authorises release of the pledge/lien. The exact operational process depends on how the units are held and the lender/AMC arrangement.
That restriction is important: you should not pledge money you may need to access for another purpose in the near term.
How quickly should you repay an LAMF?
There is no universal repayment period that is financially correct for every borrower.
A practical approach is to ask:
- How much interest will accumulate if the balance stays outstanding?
- Can you repay part of the amount without affecting essential expenses?
- Is your collateral value volatile?
- What would happen if the NAV fell sharply?
- Are you keeping an emergency fund outside the pledged investment?
If you have surplus cash, compare the interest you can avoid with the alternatives available to you.
LAMF vs personal loan: why the interest calculation matters
A personal loan usually has a defined EMI schedule. An LAMF can have a different structure depending on the lender.
| Factor | Loan Against Mutual Funds | Personal Loan |
|---|---|---|
| Security | Mutual-fund units pledged | Usually unsecured |
| Interest basis | Depends on product; may use outstanding utilisation | Usually amortising EMI |
| Collateral risk | Yes | No pledged investment |
| Market risk | NAV can fall | No market-value collateral |
| Repayment structure | Product-specific | Usually fixed schedule |
| Access to pledged investment | Restricted until release | Savings/investments remain unpledged |

What should you ask the lender before borrowing?
Ask for written answers to these questions:
- What is the annual interest rate?
- Is interest calculated daily or monthly?
- Is interest charged only on the utilised amount?
- Is there a minimum utilisation or minimum interest?
- What are all processing and other charges?
- What LTV applies to my mutual-fund category?
- What happens if the NAV falls?
- How much time do I get to restore the required margin?
- Can I make partial repayments at any time?
- When will the pledge be released after full repayment?
Do not rely only on the approved limit. The real cost depends on how much you use, for how long, and what the contract says.
FAQs
Is LAMF interest calculated daily?
It can be, depending on the lender and product structure. Check the loan agreement or sanction terms rather than assuming a daily or monthly method.
Do I pay interest on the entire LAMF limit?
Not always. Some facilities calculate interest on the amount actually utilised, but the exact method is lender-specific.
Can I reduce LAMF interest by repaying early?
If your lender calculates interest on the outstanding balance, reducing the balance sooner can reduce future interest. Check the product's repayment and charge terms.
What happens if my mutual fund value falls?
The lender may require additional collateral or repayment if the collateral falls below the required margin/LTV level. The exact trigger and process are contract-specific.
Can I sell pledged mutual funds?
Usually not freely while the units remain pledged or lien-marked. The lender generally needs to release the pledge/lien before normal redemption or switching can occur.
Is LAMF cheaper than a personal loan?
You cannot determine that from the headline interest rate alone. Compare the complete cost, repayment structure, collateral risk and your expected borrowing period.
The bottom line
LAMF interest can be attractive when you need short-term liquidity and have eligible mutual funds, but the borrowing is secured against an investment whose value can move with the market.
Before borrowing, calculate the interest on the amount you actually expect to use, check every applicable charge, understand the margin requirements and keep enough liquidity outside the pledged portfolio.
