Zerodha Intraday Brokerage Charges Calculator
Estimate brokerage, STT, GST, exchange transaction charges, SEBI turnover fees, stamp duty, gross profit and net profit for equity intraday trades with a clean, fast and practical calculator.
Assumptions used in this calculator: Zerodha equity intraday brokerage is 0.03% or Rs 20 per executed order, whichever is lower. Statutory rates may change over time, so always verify current brokerage and exchange circulars before placing live trades.
Charges decide whether a good trade stays profitable
Many traders focus on chart patterns but ignore the friction created by taxes and exchange levies. Intraday costs are small on each trade, yet repeated over dozens of trades they meaningfully reduce expectancy.
- Brokerage clarity: Know the exact buy side and sell side brokerage with Zerodha’s capped intraday pricing.
- Tax visibility: Understand how STT, GST, stamp duty and SEBI charges affect your net result.
- Better planning: Measure break-even movement per share before you enter the trade.
- Faster decisions: Use the chart and breakdown to see where your cost stack is coming from.

Expert Guide to the Zerodha Intraday Brokerage Charges Calculator
A Zerodha intraday brokerage charges calculator is one of the most practical tools an active trader can use before taking a position. Intraday trading often looks inexpensive because the headline brokerage is low, but actual trade cost is a combination of brokerage, taxes, exchange fees, regulatory charges and stamp duty. If you only estimate profit from price movement and quantity, you can easily overstate your edge. This guide explains how a quality calculator works, what each charge means, how to interpret the output, and why net profit matters more than gross profit.
What this calculator is designed to do
This calculator is built specifically for equity intraday traders who want a clear estimate of the total cost of entering and exiting a trade through Zerodha. In an intraday setup, the trade is opened and closed on the same day. Because of that, the cost profile is different from delivery investing. There are no depository participant charges for intraday square-off, but you still need to account for brokerage, Securities Transaction Tax on the sell side, exchange transaction charges on turnover, GST on selected components, SEBI turnover fees, and stamp duty on the buy side.
The tool above accepts buy price, sell price, quantity, exchange and trade direction. It then calculates turnover, gross profit or loss, every major fee component, total charges, net profit or loss, and break-even movement. This makes it useful not just as a fee estimator, but also as a trade planning system. If your expected move is too small relative to total friction, you can reject the trade before risking capital.
How Zerodha intraday brokerage is usually calculated
For equity intraday, Zerodha typically charges 0.03% or Rs 20 per executed order, whichever is lower. Since a standard intraday round trip has two executed orders, one for entry and one for exit, your brokerage is usually calculated separately for both sides. This means the maximum brokerage on a full intraday trade is generally capped at Rs 40, provided both sides hit the cap.
For example, if you buy shares worth Rs 10,000, your buy side brokerage at 0.03% is Rs 3, well below the Rs 20 cap. If you later sell shares worth Rs 10,200, your sell side brokerage at 0.03% is Rs 3.06. Total brokerage in that case is Rs 6.06. However, if each side involves very large value, the charge is capped at Rs 20 per side, keeping brokerage predictable for larger traders.
| Charge Component | Typical Basis for Equity Intraday | How It Is Applied | Why It Matters |
|---|---|---|---|
| Brokerage | 0.03% or Rs 20 per executed order, whichever is lower | Applied separately on entry and exit order values | Primary broker fee, but not the only cost |
| STT | 0.025% on sell side for equity intraday | Calculated on sell turnover only | Can materially reduce small intraday profits |
| Exchange Transaction Charges | NSE often around 0.00297%; BSE often around 0.00375% | Applied on total turnover | Important when total traded value is high |
| SEBI Turnover Fees | Rs 10 per crore, equivalent to 0.0001% | Applied on total turnover | Small individually, relevant at scale |
| GST | 18% | Applied on brokerage + exchange charges + SEBI charges | Raises effective cost above headline brokerage |
| Stamp Duty | 0.003% on buy side for equity intraday | Applied on buy turnover only | Unavoidable government levy on purchase side |
Why gross profit is not enough
Suppose you buy 1,000 shares at Rs 100 and sell at Rs 100.20. At first glance, your gross profit is Rs 200. That may look acceptable if your setup targets a quick 20 paise move. But once you apply brokerage, STT, GST, exchange transaction charges, SEBI fees and stamp duty, the actual take-home figure can be far lower. On very tight intraday systems, especially high-frequency discretionary systems with many small wins, cost leakage can convert a strategy with a positive raw win rate into a strategy with weak or even negative net expectancy.
This is why serious traders evaluate every setup in net terms. They ask a better question: after all charges, does the expected reward justify the trade? A calculator gives you that answer quickly. It also helps you understand whether increasing quantity truly improves returns or simply increases the rupee amount lost to statutory costs.
Step by step formula logic used by the calculator
- Buy turnover = buy price × quantity
- Sell turnover = sell price × quantity
- Total turnover = buy turnover + sell turnover
- Buy brokerage = lower of 0.03% of buy turnover or Rs 20
- Sell brokerage = lower of 0.03% of sell turnover or Rs 20
- STT = 0.025% of sell turnover
- Exchange transaction charge = exchange-specific rate × total turnover
- SEBI charge = 0.0001% of total turnover
- Stamp duty = 0.003% of buy turnover
- GST = 18% of brokerage + exchange charge + SEBI charge
- Total charges = sum of all above fees and taxes
- Gross profit or loss = price difference × quantity
- Net profit or loss = gross profit or loss – total charges
That final number is the key result. It tells you whether the trade is truly worthwhile after the full cost stack has been applied.
Sample statistics: how charges scale with trade size
One of the most useful insights from a brokerage calculator is that charges are not perfectly linear in practical terms. Brokerage is capped per order, but taxes and turnover-based fees keep rising with trade value. This changes the cost mix as position size increases.
| Illustrative Trade | Buy Value | Sell Value | Approx Total Turnover | Approx Brokerage Outcome | Key Observation |
|---|---|---|---|---|---|
| Small intraday trade | Rs 25,000 | Rs 25,250 | Rs 50,250 | Percentage based, below cap on both sides | Brokerage remains low, but STT and GST still matter if target is small |
| Medium intraday trade | Rs 1,00,000 | Rs 1,01,000 | Rs 2,01,000 | May approach or hit cap depending on exact value | Cap helps limit brokerage, but turnover-linked charges keep increasing |
| Large intraday trade | Rs 5,00,000 | Rs 5,05,000 | Rs 10,05,000 | Brokerage likely capped at Rs 20 per side | Beyond the cap, STT, exchange fees and taxes dominate incremental cost |
The practical lesson is simple. Once brokerage reaches its cap, larger trades do not face proportionally larger brokerage, but they do face proportionally larger taxes and turnover-linked statutory charges. So if you scale up quantity, you should still reassess your reward-to-cost ratio instead of assuming fee efficiency automatically improves.
How to use a Zerodha intraday brokerage charges calculator effectively
- Before entering a trade: Estimate the minimum price move needed to break even. If your setup offers less than that, skip it.
- When defining targets: Convert your target from gross points to net rupees. This improves consistency.
- When comparing exchanges: If a stock is available on both NSE and BSE, compare transaction charges and liquidity before execution.
- When adjusting quantity: Check whether scaling size improves your strategy or simply multiplies taxes.
- When reviewing performance: Match broker contract notes with your calculator output to validate assumptions and detect slippage or mismatch.
Common mistakes traders make while estimating intraday costs
The first mistake is looking only at brokerage and ignoring taxes. In reality, STT and GST often make a visible difference, especially on thin-margin intraday systems. The second mistake is forgetting that brokerage is charged on both executed orders. The third mistake is treating gross points as if they directly translate to net rupees. The fourth mistake is ignoring exchange selection. Even when the difference in transaction charges is small, repeated trades can make it meaningful over a month or a quarter.
Another frequent error is assuming every cost is charged on total turnover in the same way. That is not true. For example, STT for equity intraday is generally levied on the sell side, while stamp duty is generally applied on the buy side. A good calculator models these correctly, which is exactly why precision matters.
Why break-even movement per share is a powerful metric
Many traders think in points or paise. That makes break-even movement per share an excellent risk filter. If your total charges are Rs 85 and your quantity is 500 shares, you need a movement of Rs 0.17 per share just to cover fees. Any planned target below that is structurally weak unless you have exceptional execution quality. This metric is especially useful for scalpers and momentum traders who operate with tight targets and frequent entries.
Authoritative references for taxes, regulation and fee context
Because brokerage schedules, regulatory fees and tax structures can be updated, traders should cross-check the latest official sources from regulators and government portals. The following links are useful starting points for validating regulatory context and statutory frameworks that influence trading charges:
- Securities and Exchange Board of India (SEBI)
- Department of Revenue, Ministry of Finance
- India Code Government Repository
These sources are valuable when you want to verify turnover-related levies, stamp-duty frameworks, tax structure context or regulatory circulars affecting securities trading.
Final thoughts
A Zerodha intraday brokerage charges calculator is not just a convenience widget. It is a decision tool that helps you trade with realistic expectations. In active trading, small fee differences compound quickly. By calculating the true round-trip cost in advance, you can set more intelligent entry criteria, refine position sizing, define practical profit targets and reduce the number of trades that only look attractive before costs are applied.
Use the calculator every time you change quantity, stock price range or exchange. Review your contract notes periodically and compare them with the model. Most importantly, judge performance on net outcomes, not gross gains. That single shift can improve both your discipline and your long-term trading process.
