Leveraged trading can amplify returns — but it also carries a daily price tag that many traders ignore until it directly hurts their P&L. When you hold a position through the Margin Trading Facility, the broker is not offering free capital. Every day the position remains open, a specific interest charge accrues on the funded amount. This is what traders refer to as MTF charges per day.
Understanding this daily cost is far more than an accounting exercise. It directly shapes your break-even point, your profit expectations, and your decision about when to exit. A stock that gains 2% over two weeks might still leave you at a loss if the accumulated MTF charges exceeded your profit during that period.
This guide walks you through how MTF charges work, how to calculate them with precision, and why factoring them into every leveraged trade is non-negotiable for anyone who uses margin seriously.
What Is MTF — And Why Daily Charges Are the Core of the Cost
Before getting into the calculation mechanics, it is useful to establish a clear foundation. Understanding what is MTF sets the context for why daily charges exist and how they accumulate.
MTF — the Margin Trading Facility — is a SEBI-regulated product where a stockbroker lends funds to a trader to purchase approved securities. The trader pays only a portion of the trade value as margin; the broker funds the rest. In exchange, the trader pays interest on the borrowed amount for every calendar day the position is held.
Unlike intraday trades, which are squared off on the same day at no borrowing cost, MTF positions carry forward. Each additional day means another day of interest — and those daily charges can collectively become a significant cost over even a two-week holding period.
The Formula: How to Calculate MTF Charges Per Day
The calculation is direct and easy to apply to any trade:
Daily MTF Charge = Funded Amount × Daily Interest Rate
Here is a worked example:
- Stock purchase value: ₹2,00,000
- Margin paid by trader: ₹50,000 (25%)
- Funded amount (broker’s contribution): ₹1,50,000
- Broker’s daily interest rate: 0.04% (approx. 14.6% per annum)
Daily MTF charge = ₹1,50,000 × 0.04% = ₹60 per day
Over a 10-day hold: Total interest = ₹600
This means the stock must appreciate by at least ₹600 on a ₹2 lakh position just to cover the interest cost — before accounting for brokerage, STT, exchange charges, and GST. Suddenly, a seemingly modest daily charge starts to look more meaningful when compounded over the holding period.
To get precise MTF charges per day for your specific trade setup, a dedicated calculator simplifies the process and eliminates manual calculation errors.
Calculating Your Effective Break-Even Price
Once you have the daily charge, you can calculate the break-even price for any holding period:
Break-Even Price = (Total Investment + Total MTF Charges + All Other Costs) ÷ Number of Shares
This figure tells you the exact price at which your trade becomes profitable net of all costs. Setting your target above this price — with a reasonable buffer — is the disciplined way to plan any MTF trade.
Factors That Determine How Much You Pay
MTF charges are not the same for every trade. Several variables determine your actual daily cost:
The Funded Amount — the more capital you borrow, the higher your daily charge. Paying a higher margin upfront directly reduces your interest outflow.
Broker’s Interest Rate — this is the single most influential variable. Brokers in India charge anywhere from 0.025% to 0.055% per day (roughly 9% to 20% annualised). The difference between a 9% broker and an 18% broker on a ₹5 lakh funded position works out to approximately ₹3,750 extra interest per month.
Holding Period — every additional day multiplies the cost. A 7-day hold costs exactly double what a 3-4 day hold does on the same position. There are no grace days and no interest waivers.
Scrip Movement — while this doesn’t affect the interest rate, it influences how long you hold. A slow-moving stock that doesn’t reach your target for three weeks accumulates far more interest than a fast-moving stock that hits target in four days.
A Practical Five-Step Framework for Managing MTF Costs
Experienced traders do not just calculate MTF charges after the fact — they build them into the trade plan before entry.
Step 1: Set a hard exit deadline. Decide before entering: “I will not hold this beyond Day X.” This prevents indefinite carries driven by hope rather than strategy.
Step 2: Calculate total charges for your maximum holding period. Know the worst-case interest outflow upfront. If you plan to hold for up to 15 days, calculate 15 days of charges and treat that as a sunk cost.
Step 3: Set your net profit target — not gross. Your target price should yield your expected profit after deducting interest, brokerage, and taxes. A gross ₹3,000 profit that leaves ₹900 net after costs is not the same trade you thought it was.
Step 4: Place your stop-loss accounting for interest. If the trade moves against you on Day 3, you are already carrying three days of charges. Your stop-loss should reflect the full cost basis, not just the entry price.
Step 5: Review every morning. Check whether the stock is on track relative to your cost accumulation. If it hasn’t moved by Day 5 and you planned for a 3-day trade, the economics have already changed.
Comparing Brokers on MTF Pricing — Why It Matters More Than Brokerage
Most traders compare brokers on flat brokerage fees — ₹10 or ₹20 per order. But for active MTF users, the interest rate differential is far more consequential.
On a ₹10 lakh funded position over 30 days:
- At 9% p.a. (0.0247% per day): Interest ≈ ₹7,400
- At 14% p.a. (0.0384% per day): Interest ≈ ₹11,500
- At 18% p.a. (0.0493% per day): Interest ≈ ₹14,800
The difference between the highest and lowest rate in this example is over ₹7,400 per month — on a single position. Multiply that across multiple concurrent MTF positions over an active trading year, and the savings from choosing the right broker become substantial.
Conclusion: Daily Charges Define the Trade’s True Economics
The true cost of any leveraged position is never just the entry price plus brokerage. MTF charges per day accumulate quietly and consistently, reshaping the trade’s economics with every passing session.
Calculate your daily charges before you enter. Know your break-even price. Set targets that account for all costs — not just the price movement you expect. That approach does not just protect your capital; it builds the kind of disciplined trading mindset that separates consistent traders from those who are perpetually surprised by their P&L statements.
