Not every investor has enough capital to take advantage of a market opportunity when it arises. The Margin Trading Facility (MTF) addresses this by allowing investors to buy shares with partial funding from their broker. However, this borrowed amount comes at a cost known as the MTF interest rate. Whether you hold a position for a few days or several weeks, interest continues to accrue on the funded amount and can affect your overall returns. Understanding what is MTF interest rate, how it works, and its impact on profitability is essential before using margin trading.
Key Takeaways
-
The MTF interest rate is the borrowing cost charged by a broker on the funded portion of an MTF trade.
-
In India, MTF interest rates typically range from 9.5% to 18% per annum for standard plans, with some discount brokers offering rates below 10% under specific subscription-based plans.
-
Holding an MTF position for a longer period increases the total interest cost, which reduces net returns and raises the trade's break-even point.
-
SEBI regulates the MTF framework and periodically reviews the rules governing margin trading facilities and broker funding requirements.
MTF Interest Rate meaning
The MTF interest rate meaning refers to the cost of borrowing funds from your broker when you use the Margin Trading Facility (MTF). Under MTF, you pay a part of the trade value as margin, while the broker funds the remaining amount. The broker then charges interest on this funded portion at a specified annual rate, which accrues daily on the outstanding balance.
To put it plainly: if your broker funds ₹75,000 of a ₹1,00,000 trade and the interest rate is 12% per annum, you owe them approximately ₹24.66 per day on that amount. Every day you hold the MTF position, this interest accrues.

How Does MTF Interest Work?
When you place a buy order using MTF, here is what happens behind the scenes:
-
Step 1: You provide the margin SEBI regulations also require a minimum 20% upfront margin for cash market trades. For MTF trades, brokers must collect the higher of the two, the 25% MTF requirement or the applicable cash market margin, whichever is greater.
-
Step 2: Your broker funds the rest The broker finances the remaining amount (up to 75%) using its own capital or borrowed funds. The purchased shares are automatically pledged to the broker as collateral through the depository-based pledge mechanism mandated by SEBI.
-
Step 3: Interest begins accruing From the very next day after your position is taken, the broker starts charging interest on the funded amount. This interest accrues daily, including on weekends and public holidays. It is not charged monthly or only on trading days.
-
Step 4: Daily charging mechanism The daily interest is calculated by dividing the annual interest rate by 365, then multiplying by the outstanding funded amount. This charge is added to your account each day the position remains open.
-
Step 5: Settlement Interest is typically debited from your linked trading account or adjusted against your available funds. When you close the MTF position, either by selling the shares or converting to regular delivery by paying the outstanding funded amount, the interest stops accruing. If you do not maintain the minimum required margin, your broker may issue a margin call or square off your position.
How is MTF Interest Rate Calculated?
MTF interest rates are calculated on the funded amount, that is, the portion your broker pays, not on the total trade value. The formula is straightforward:
Daily Interest = (Funded Amount × Annual Interest Rate) ÷ 365
Total Interest = Daily Interest × Number of Days Held
Numerical Example
Suppose you want to buy shares worth ₹1,00,000. You pay 25% (₹25,000) as the margin, and your broker funds the remaining 75% (₹75,000). The broker's MTF interest rate is 12% per annum.

|
Interest for 30 Days |

As you can see, holding an MTF position for 30 days costs approximately 3x more than holding it for 10 days. This accumulation makes the holding period one of the most important variables in MTF profitability.
Important note on taxes: GST at 18% is levied on the interest amount in addition to the figures above. Always factor in GST when calculating your actual cost.
Factors That Affect MTF Interest Rates
Several factors influence MTF interest rates and determine the cost of borrowing through the Margin Trading Facility. A key factor is the broker's cost of funds. Brokers borrow capital from banks, NBFCs, and other sources, and higher borrowing costs often lead to higher MTF rates.
RBI monetary policy also plays an important role. Changes in the repo rate affect lending costs across the financial system, which can influence MTF pricing. In addition, each broker follows its own pricing strategy, resulting in interest rates that generally range from approximately 9.65% to 18% per annum for standard plans, with some subscription-based plans offering rates below 10%.
The borrowing amount may also affect the rate, as some brokers offer lower rates for larger positions. While the holding period does not change the interest rate itself, it increases the total interest payable over time.
Regulatory changes introduced by SEBI can also affect broker funding costs and, indirectly, MTF interest rates. SEBI's June 2026 consultation paper, which proposes expanding broker funding sources to include NCDs, could, if implemented, alter the cost of funds for brokers and potentially impact the rates passed on to investors. See the 'Recent Regulatory Developments' section for details.
Impact of MTF Interest Rates on Trading Returns
MTF interest rates are a direct cost that comes out of your trading profit. The higher the interest rate, the longer the holding period, and the larger the funded amount, the more your returns are eroded.
-
Raising the Break-Even Point
Every time you use MTF, you are first trying to recover the interest cost. This shifts your break-even upward. For example, if you borrow ₹75,000 at 12% per annum and hold for 15 days, your interest cost is approximately ₹370. This means the position must move up by at least ₹370 just to cover borrowing costs before accounting for brokerage, STT, GST, and pledge charges.
-
Compounding Effect on Longer Holds
Interest on MTF is simple interest (not compounded), but the accumulation over time can be significant. A 30-day hold costs three times what a 10-day hold costs. A 90-day hold can make the interest burden substantial enough to eliminate an otherwise reasonable gain.
-
Amplification of Losses
If the stock moves against your position, your losses are compounded by the interest cost. You lose on the position and still pay for the borrowed funds. This is why MTF is generally more suitable for traders with short- to medium-term views rather than those trying to hold indefinitely.
-
Leverage and Return Amplification
On the positive side, MTF allows you to control a larger position than your capital permits. If you invested ₹25,000 and took a ₹1,00,000 position (4x leverage) and the stock gained 10%, your gross return is ₹10,000 — on a capital outlay of just ₹25,000. That is a 40% gross return on capital. But deducting the interest for the holding period reduces this net return, and the math quickly tightens.
Example of MTF Interest Cost Calculation
Let us walk through a complete, realistic example.
Scenario: You spot an opportunity in a Group I stock currently trading at ₹500 per share. You want to buy 200 shares (total value: ₹1,00,000). You have ₹25,000 available and use MTF to fund the rest.

This example illustrates how even modest adverse moves, combined with interest costs, can turn small losses into bigger ones. The longer the holding, the heavier the interest burden.
Things to Consider Before Using MTF
Before using MTF, confirm that the stock is eligible under the broker's approved list and understand the total borrowing cost involved. Interest accrues every day, including weekends and holidays, making holding period a key factor in profitability.
Calculate your break-even point by considering interest, brokerage, taxes, and other charges. Since MTF uses leverage, losses can increase just as quickly as profits. Investors should also be prepared for margin calls if account equity falls below required levels.
As MTF is primarily designed for short- to medium-term trading, long-term investors may find the ongoing interest cost less suitable.
The list of MTF-eligible Group I securities is published on BSE and NSE websites and is reviewed periodically. A stock that qualifies for MTF today may be removed from the eligible list if its liquidity or risk profile changes — which could force position conversion or early exit.
Additionally, factor in depository pledge and unpledge charges levied by CDSL or NSDL, which apply each time an MTF position is opened or closed. These are separate from brokerage and can add to the total cost of MTF trades, particularly for high-frequency users.
How to Reduce MTF Interest Costs
You can manage MTF costs more effectively by following a few practical steps:
-
Keep holding periods short, as interest accrues daily on the funded amount.
-
Enter only high-conviction trades with a clear target price and stop-loss strategy.
-
Compare MTF interest rates across brokers, as even small rate differences can significantly affect long-term costs.
-
Monitor open positions regularly and exit losing trades promptly to limit both losses and interest expenses.
-
Borrow only the amount required for your strategy instead of using the maximum available leverage.
-
Consider converting the position to regular delivery if your short-term trade becomes a long-term investment.
Recent Regulatory Developments
The current MTF framework is governed by Clause 4 of Chapter 1 of SEBI's Master Circular for Stock Exchanges and Clearing Corporations, dated December 30, 2024. Investors and traders should be aware of the following recent and proposed changes:
September 2024 — Cash Collateral as Maintenance Margin (Effective October 1, 2024)
SEBI introduced a significant operational change: securities purchased under MTF using cash collateral can now be counted as maintenance margin, removing the earlier requirement to maintain a separate margin.
However, this comes with a higher margin condition — where funded stocks are considered as maintenance margin to the extent of cash collateral provided, the applicable margin is VaR + 5 times the Extreme Loss Margin (ELM), rather than the standard VaR + 3 ELM. This applies only to Group I securities. Brokers must also report MTF exposure to the exchange by 6:00 PM on T+1 day.
June 2026 — SEBI Consultation Paper on MTF Framework Review
On June 18, 2026, SEBI released a consultation paper proposing a comprehensive review of the MTF framework. Key proposals include the following:
-
Raising the minimum net worth requirement for brokers offering MTF from ₹3 crore to ₹5 crore.
-
Allowing LLP-structured brokers, in addition to corporate brokers, to offer MTF.
-
Expanding broker funding sources to include borrowing via Non-Convertible Debentures (NCDs) and other debt instruments.
-
Making eligible collateral uniform across normal cash market and MTF transactions.
-
Permitting fungibility of unencumbered funds and securities between MTF and non-MTF client ledgers.
-
A 30-day grace period for passive breaches of single-client exposure limits.
-
A separate 30-day rebalancing period when a security is reclassified out of Group I, giving brokers time to adjust positions.
-
Enabling an auto-pledge mechanism for funded stocks.
-
A proposal to review Group I security classification criteria through a separate forthcoming consultation paper.
These are proposals under public consultation (deadline: July 9, 2026) and are not yet finalised. If implemented, they could affect broker eligibility, funding costs, and MTF interest rates offered to investors.
Conclusion
The MTF interest rate is the cost of borrowing funds from your broker when using the Margin Trading Facility. Since interest accrues daily on the funded amount, it directly affects your trading returns and break-even point. In India, MTF is regulated by SEBI and is available only on eligible securities. While MTF can help traders increase market exposure, the associated interest cost makes it most suitable for short- to medium-term positions.
Understanding these costs can help you use leverage more effectively and make informed trading decisions.
