How these numbers are produced

Most calculator sites hard-code a charge into a script and never touch it again. Every statutory rate on TradeCrunch instead lives in a single maintained registry, each entry carrying its source and the date it was last checked. The brokerage calculator prints that date and links the sources directly on the page, so you can judge how stale the numbers are before trusting them.

The statutory charges currently applied are the F&O securities transaction tax rates effective 1 April 2026, the NSE transaction charge slab effective 1 March 2026, SEBI turnover fees of ₹10 per crore, 18% GST on brokerage and exchange fees, and state stamp duty on the buy side. The full method is on the About & Methodology page.

Nothing you enter leaves your browser

There is no account and no server-side database. Calculators compute in the page itself. The trading journal keeps trades in your browser's local storage on your own device — which also means clearing site data erases them, so export a CSV backup periodically.

Frequently Asked Questions

  • Yes. Every calculator and the trading journal are free, with no account, no signup and no usage limit.
  • No. Every tool runs entirely in your browser. Trading journal data is saved in your browser's local storage on your own device and is never uploaded. Clearing your browser data deletes it permanently, so export a CSV backup before you do.
  • Statutory charges reflect the F&O STT rates effective 1 April 2026 and the NSE transaction charge slab effective 1 March 2026. Every rate is kept in one maintained registry with its source and the date it was last checked, shown on the brokerage calculator page.
  • No. TradeCrunch is not a SEBI-registered investment adviser or research analyst. The tools produce arithmetic estimates from the inputs you supply. They are not investment, tax or legal advice. See the full disclaimer.
