Trading Tools for Indian Stock Market Investors
Use LetsThinkWise trading tools to understand the real cost of trading in India. These calculators help you compare broker charges, calculate brokerage, estimate net profit or loss, and understand how different charges affect your final trading result.
Many traders only look at brokerage, but the actual trading cost can include brokerage, STT, GST, exchange transaction charges, SEBI charges, stamp duty, DP charges, AMC, call and trade charges, and auto square-off charges. Our calculators are designed to make these costs easier to understand before you open or switch a demat account.

Trading charges explained
Brokerage
The fee your broker charges per order or as a percentage of turnover. Discount brokers often use flat per-order fees; full-service brokers may charge a percentage with caps.
STT / CTT
Securities Transaction Tax (or CTT on commodities) is a statutory charge on eligible trades. Rates differ for delivery, intraday, futures, and options.
GST & exchange fees
GST applies on brokerage and certain transaction charges. Exchanges levy turnover-based fees that vary by segment (NSE vs BSE).
DP charges & AMC
DP charges apply when you sell shares from demat. Annual Maintenance Charges (AMC) are yearly account fees—often zero at discount brokers for active accounts.
Why trading cost comparison matters
Two brokers can look similar on advertised brokerage, but total cost differs by trading frequency, segment mix, order size, DP events, and API use. A passive SIP investor may care more about AMC and DP; an intraday or F&O trader may care more about per-order caps and turnover charges.
That is why LetsThinkWise tools use the same verified tariff data across calculators—so you can shortlist brokers by profile, then validate with exact volumes or a single trade.
