What a holding really cost, what a trade really costs, and what a dividend really pays
Everything here runs in your browser. Files are never uploaded.Three questions come up again and again once somebody owns shares, and a broker app answers none of them properly: what the holding actually cost after several purchases at different prices, what a round trip costs once every levy is added to the brokerage, and what the dividends amount to over years rather than over a quarter. These work each one out from figures you read off your own statements.
Stock Average Calculator takes every purchase as a quantity and a price and returns the weighted average. The reason it exists is that the obvious method is wrong: adding the prices and dividing by how many times you bought treats a ten-share nibble and a nine-hundred-share commitment as equals. Ten at 100 and ninety at 200 average 190, not 150, and the naive figure always errs in the flattering direction. It also answers the question underneath: how many more shares at what price it would take to move that average, and when that cannot be done.
Brokerage Calculator itemises a round trip. Exactly one line on a contract note is the broker's own rate, and it is an input here with named starting shapes rather than a number we invented. Securities transaction tax, the exchange transaction charge, the SEBI turnover fee, stamp duty and GST are the same for everybody, and each one names the circular it was read from and the day it was read. The figure worth looking at is the break-even sell price: how far the price has to move before the trade has made anything at all.
One thing that page will tell you and most will not: STT on derivatives rose on 1 April 2026, futures from 0.02% to 0.05% and options from 0.10% to 0.15% of premium. Calculators that have not been updated understate an F&O trade.
Dividend Calculator is written for American holdings and keeps two numbers apart that are constantly confused. Yield is the dividend against today's price, which is what a new buyer would get. Yield on cost is the dividend against what you paid, which is what your own holding pays you, and after fifteen years of increases they are nowhere near each other.
Capital Gains Tax Calculator covers the Indian side of selling, and CAGR Calculator turns a start value, an end value and a number of years into the annual rate that connects them.
No price, yield or broker tariff is published on any of these pages. Estimates only, not financial advice.
Multiply each purchase by its quantity, add the amounts, and divide by the total shares. Adding the prices and dividing by the number of purchases is the common shortcut and it is wrong whenever the purchases were different sizes, which is almost always.
Brokerage, securities transaction tax, the exchange transaction charge, the SEBI turnover fee, stamp duty and GST, plus a depository charge on a delivery sell. Only the first and the last are your broker’s own; the rest are fixed by the government or the exchange and are identical everywhere.
Yes, on 1 April 2026 for derivatives: a sold futures contract went from 0.02% to 0.05% and a sold option from 0.10% to 0.15% of the premium. Delivery stayed at 0.1% on each leg and intraday at 0.025% on the sell.
No. Listed shares in India are taxed first in, first out: the oldest shares are treated as sold first at what they actually cost. The average answers what the whole position cost you, which is a different question from what a partial sale is taxed on.
Both, by tool. The brokerage and capital gains pages use Indian rules and rupees. The dividend page uses dollars and American conventions. The stock average and CAGR pages are neutral and work for either market.
No. Every calculator here runs in your browser, so your holdings, prices and broker tariff stay on your own device and nothing is kept after the page is closed.
