What this site is, and is not
- Arithmetic, not advice. The calculators work out what your own numbers mean: what a trade costs, what you risk, what you owe in tax. We never tell you what to buy or sell.
- No live prices. You type the prices from your own broker. Nothing you type leaves your browser.
- Checked rates. Charges and tax rates come from NSE, SEBI, the Income Tax Department and brokers’ own pages, each with the date we checked it.
