F&O Turnover Calculator
Free manual calculator for the ICAI GN 2025 turnover method. Runs in your browser.
GN 2025 formula
Turnover = favourable differences + unfavourable differences + option-sale premium, unless that premium is already included in the transaction result.
How it works
- Enter favourable and unfavourable differences from your broker report.
- Add option-sale premium only if your report has not already included it.
- You get a GN 2025 turnover estimate for audit-threshold checks.
- Use it to check audit applicability.
Why the formula matters
AY 2026-27 onward uses the ICAI GN 2025 position. Option-sale premium is included, but it should not be counted twice where the broker P&L already includes it in the per-trade result. See F&O turnover for the full background.
