How changes are made
- Rates are reviewed after every Union Budget, after exchange circulars that change charges, and at least every three months.
- When a rate changes, the calculator code, the guides that mention it, the header rate ticker and the worked examples are updated together.
- Each worked example is recalculated and matched with the calculator before publishing.
- The page date is updated to the review date.
What the calculators assume
- NSE rates are used for equity and F&O; BSE charges differ by scrip group.
- Broker presets use each broker’s standard plan. Special plans, promotions and minimum-charge rules for very small orders may differ.
- DP charges are counted once per sell trade for a single scrip.
- Rounding follows normal two-decimal rounding; brokers may round each line differently, so totals can differ by a few paise.
