About Stamp Duty On Trades Calculator

Stamp duty is levied on the buy side at a rate per unit of value that varies by segment: delivery trades pay the full rate while intraday and derivative trades pay a fraction. It is small per trade but material for high-turnover strategies.

Formula

Stamp duty

Duty = (value / 100,000) × rate per 100,000 × segment multiplier

Frequently Asked Questions

Is duty charged on both legs?

Normally only on the purchase leg, which is why intraday round trips pay it once.

Does it vary by state or region?

It did historically; many jurisdictions have moved to a single uniform rate collected centrally.
