High-performance, deterministic brokerage and tax calculator for Indian equity markets. Kairocal is a powerful tool designed to provide Indian equity, F&O, and currency traders with high-precision charge reconciliation and transparent tax calculations. It helps users calculate exact brokerage, STT, NSE transaction fees, DP charges, and GST.




Hi Product Hunt community,
Most brokerage calculators in the Indian market give rough approximations rather than actual contract-note reality. Traders often calculate an expected profit only to realize after settlement that statutory charges, DP fees, IPFT, exchange levies, and GST cut deeper into margins than anticipated.
I built Kairocal to solve this with a deterministic, high-precision calculation engine.
Here is what Kairocal brings to the table:
Complete Statutory & Depository Breakdown: Computes exact brokerage, STT, NSE/BSE transaction fees, SEBI turnover charges, IPFT, stamp duty, DP charges per ISIN, and 18% GST.
Segment Coverage: Full calculation support across Equity Delivery (CNC), Intraday (MIS), MTF, Futures, Options, Commodities, and Currencies.
Side-by-Side Broker Benchmarking: Run a single trade scenario to compare realized net P&L and total charge impact across Zerodha, Groww, Angel One, Dhan, Upstox, FYERS, ICICI Direct, HDFC Securities, and Kotak Securities.
Algorithmic Break-Even Calculation: Uses a precise binary search across the non-linear charge stack to show the exact exit price needed for zero net P&L.
Contract Note Ledger: Generates a structured breakdown replicating actual institutional settlement statements.
The tool is completely free and accessible directly in your browser. I would appreciate your feedback on the charge calculations, broker coverage, or any features you would like added next.
