What Are MTF Interest Rates? Meaning & Cost Breakdown

In Margin Trading Facility (MTF), one can buy stocks by paying only a portion of the order value, while your broker funds the remaining amount. However, the brokers charge daily interest on the financed amount, known as the MTF Interest Charges. 

These charges can vary depending on the different brokers, but generally range from around 0.04% per day (approximately 14.6% per year) to as high as 0.05% per day (approximately 18.25% per year). In simple terms, the MTF interest charge is a daily charge you need to pay on the extra buying power.

Read along to know the MTF charges on Groww, how interest is calculated, and the factors affecting the MTF interest rate.

Factors Affecting MTF Interest Rates

Groww’s MTF interest rate is currently fixed at 14.95% per year, but interest rates can differ across brokers. Here are some major factors affecting MTF interest rates:

Base Interest Rates

If the overall cost of borrowing in the economy rises, brokers may also raise their MTF interest rates to match those higher funding costs. Conversely, when the base interest rate in the economy is lower, brokers can access funds at cheaper rates and thus reduce the MTF interest rates.

Broker’s Funding Setup

Brokers fund your trades using their own or borrowed capital. Any change in their funding cost can affect the rate they charge investors. If their borrowing costs increase, they might revise the margin trading interest rate accordingly.

Amount of Funding Borrowed

Some brokers charge different rates depending on how much you borrow. Larger borrowings may sometimes get slightly lower rates, while smaller ones might cost a bit more.

Holding Period

MTF interest is charged daily. The longer you hold your position, the more interest you pay. So, short-term trades generally have lower interest costs than long-term ones.

Policy or Regulatory Changes

Any changes to SEBI or exchange regulations can also affect MTF pricing. Moreover, every broker sets its own MTF interest rates based on its internal policies and cost structures. Hence, the MTF charges may vary across platforms.

Economic Conditions

Broader economic indicators also play a role in determining MTF rates. When the economy is strong and market sentiment is positive, investors are generally more willing to take risks, and MTF rates tend to remain stable or even decline slightly. During periods of uncertainty or high volatility, brokers may revise their rates upward to manage increased risk.

MTF Rate Structure on Groww

Groww charges daily interest on the Marginal Trading Facility (MTF) for the total funded amount. The table below shows the current MTF charges on Groww:

How to Calculate MTF Interest Rates?

To calculate the Marginal Trading Interest Rates, you can use the following formula:

Here, the daily interest rate is the annual interest rate divided by 365. 

Let’s understand this with an example:

Suppose you purchased 100 stocks worth ₹1,00,000 each, with a 25% haircut.

Therefore, based on the above, the amount funded by you: ₹25,000

Amount funded by Groww: ₹75,000

Daily interest rate charged by Groww: 0.041%

Hence, Daily MTF charges = Funded Amount × (Daily Interest Rate)

= ₹75,000 × 0.041%

= ₹30.75

Now, for a 30-day holding period, the total interest cost will be = ₹30.75 × 30 = ₹922.50

Comparison of MTF Interest Rates Across Brokers

How MTF Interest Influences Profitability?

Reduces Overall Returns

The interest charged on the amount borrowed through MTF is a direct cost. It gets deducted from your gross trading profits, lowering the final return you take home.

High Holding Period Leads to Higher Interest Rates:

Since MTF interest is calculated daily, the cost keeps increasing the longer you hold the position. As a result, the accumulated interest can reduce your potential profits.

Increases Your Losses:

If the trade turns unfavourable, you not only face a loss from the stock’s price movement but must also pay the accumulated interest on the borrowed funds. This can result in a total loss larger than initially anticipated.

Lowers Net Return on Investment (ROI)

Profitability ultimately depends on the net returns after accounting for all associated costs, including MTF interest. A trade that appears profitable based solely on price movement may yield a much lower, or even negative, net ROI once interest charges are included.

Margin Trading Facility (MTF) is a valuable feature for traders seeking higher leverage, provided they understand its cost structure. Since MTF interest is charged daily, monitoring your holding period and calculating potential returns after interest is essential. By using MTF wisely and comparing interest rates across brokers, traders can optimise costs and improve overall profitability.

It is also essential to understand the risks associated with MTF, including the potential for greater losses, minimum balance requirements, liquidation risks, and interest costs. Margin Trading Facility can amplify both profits and losses, and improper use can lead to significant financial strain. Therefore, approach MTF with caution and clear investment goals.
