F&O turnover calculator
Turnover is the number that decides whether you need a tax audit, and brokers often get it wrong. This calculator uses the ICAI absolute-sum method: turnover is the absolute sum of your realised profit and loss, with no option-premium add-back. Paste your per- trade P/L and see the real figure.
F&O trades (futures + options)
Paste your realised profit or loss per trade or settlement, one per line. Losses as negatives, e.g. -8200 or (8200).
Intraday equity (speculative)
Tracked separately from F&O. Same method: one realised P/L per line.
Estimate for your reference, not tax advice. Turnover here is the ICAI absolute-sum of realised P/L; it is a tax measure, not the contract value your broker may quote. Verify with a qualified CA.
The formula, in one line
F&O turnover = Σ |realised profit or loss| per trade or settlement. Add the profit on every winning trade to the absolute value of the loss on every losing trade. The ICAI 8th-edition Guidance Note (14 August 2022) removed the old “plus premium on sale of options” add-back, so for AY 2022-23 onward it is absolute P/L only. Full worked examples are in the turnover calculation guide.
Why your broker's number can differ
Many broker Tax P&L exports still add option sell-side premium into turnover, or use a different basis, which inflates the figure. They also cannot combine multiple brokers. The audit thresholds (₹2 cr for 44AD, ₹10 cr for 44AB) work off the ICAI figure, so an inflated broker number can scare you into an audit you do not need. See the Zerodha turnover mismatch explainer for the detail.
What to do with the number
Once you have your turnover, run it through the audit checker to see if a 44AB audit applies, and the advance-tax calculator to schedule your installments. To get turnover straight from a broker statement across every broker you trade with, upload it to Aktai Tax.
FAQ
How is F&O turnover calculated for income tax?
F&O turnover for income tax is the absolute sum of realised profit and loss across all trades and settlements. You add the profit on winning trades to the absolute value of the loss on losing trades. Per the ICAI 8th-edition Guidance Note (14 August 2022, applicable AY 2022-23 onward), the older method of adding the premium received on sale of options has been removed: it is absolute P/L only. This turnover figure decides audit applicability and the 44AD presumptive option, it is not the contract or notional value.
Why is my broker turnover different from this?
Broker Tax P&L reports often still add option sell-side premium to turnover, or compute turnover on a different basis, which inflates the number. Some brokers also cannot aggregate across multiple brokers. The ICAI absolute-sum method gives a smaller, correct figure for tax purposes. When the numbers differ, the ICAI method is the one your CA and the audit thresholds use.
Is intraday equity turnover added to F&O turnover?
They are computed the same way (absolute sum of realised P/L) but are reported under different heads. Intraday equity is speculative business income; F&O is non-speculative business income. Keep the two turnovers separate, although both count toward your overall audit-threshold picture.
Does a high turnover mean I owe more tax?
No. Turnover is not income. You are taxed on your net profit, not on turnover. Turnover only decides whether a tax audit applies and whether you can use the 44AD presumptive scheme. A trader with ₹3 crore turnover and a ₹40,000 net loss owes no tax on that activity, though the loss year can still raise audit questions.
