Brokerage Calculator
Estimate brokerage, taxes, total charges, and your net profit/loss for a trade.
Why a brokerage calculator matters
Most traders focus on entry and exit price, but your actual outcome depends on charges just as much as price movement. Brokerage, STT/CTT, exchange transaction charges, SEBI fees, GST, and stamp duty can quietly reduce your returns. A brokerage calculator helps you see the true net P&L before you place a trade.
If you trade frequently, even small cost differences can compound into a meaningful number over months and years. That is why professional traders treat cost analysis as part of risk management.
What this calculator includes
- Turnover: Buy value + sell value
- Brokerage: % on both sides, with optional per-order cap
- STT/CTT: Applied on sell side in this model
- Exchange transaction charges: Applied on turnover
- SEBI charges: Applied on turnover
- GST: Applied on brokerage + exchange charges + SEBI charges
- Stamp duty: Applied on buy side
- Net profit/loss: Gross P&L minus total charges
- Break-even sell price: Estimated price where net P&L becomes zero
How to use the brokerage calculator
1) Choose a preset or set your own rates
Use a preset for quick estimation, then switch to custom values based on your broker’s exact fee sheet. If your broker uses zero brokerage for delivery, set brokerage percentage to 0.
2) Enter trade details
Add your buy price, expected sell price, and quantity. The tool computes gross P&L first, then deducts all configured charges.
3) Read the breakdown, not just net P&L
The detailed line items reveal where your money is going. For active traders, this is often the key insight for improving strategy profitability.
A quick practical example
Suppose you buy 100 shares at ₹100 and plan to sell at ₹102. Gross profit looks like ₹200. But once all fees are included, your net could be much lower. In tight intraday trades, this gap can make the difference between a profitable system and a losing one.
How to reduce trading costs
Compare effective cost per trade
Don’t compare brokers by headline brokerage alone. Compare your total expected cost under your typical trade size and frequency.
Avoid overtrading
Every trade incurs charges. If your setup quality is weak, transaction costs can eat most gains.
Increase selectivity
Fewer high-conviction trades often produce better post-cost performance than many marginal trades.
Common mistakes traders make
- Ignoring taxes and fees in backtests
- Using unrealistic slippage assumptions
- Calculating only gross return percentages
- Not tracking monthly total cost as a performance metric
Final takeaway
A brokerage calculator is not just a convenience tool; it is a discipline tool. It keeps you focused on net outcome, which is what actually matters. Use it before placing a trade, and use it when reviewing your strategy performance.
