What is Margin Trading Facility (MTF)?

Margin Trading Facility allows investors to purchase shares by paying a partial amount, while the broker funds the remaining amount. The broker charges interest on the funded amount, known as the MTF interest rate.

In India, MTF is regulated by the Securities and Exchange Board of India (SEBI), and only approved stocks can be purchased under margin trading.

How to Calculate MTF Interest Rate?

MTF interest is charged only on the funded amount, not on the total trade value.

MTF Interest Calculation Formula

Interest = Funded Amount x Interest Rate x Number of Days ÷ 365


Example of MTF Interest Calculation

Let’s understand with a practical example:

  • Total shares purchased: ₹1,00,000
  • Investor margin paid: ₹40,000
  • Broker funded amount: ₹60,000
  • MTF interest rate: 12% per annum
  • Holding period: 30 days

Calculation:

Interest = (60,000 × 12% × 30) / 365
Interest = (60,000 × 0.12 × 30) / 365
Interest = ₹591.78

So, you will pay approximately ₹592 as MTF interest for 30 days.
