What This Trade Keeps After Every Cost
Price charts show the gross move between your entry and exit, but your brokerage account only keeps what remains after commissions, bid-ask spreads, exchange clearing fees and statutory transaction taxes. The Global Cost Desk lets traders in the United States, United Kingdom, Europe, Asia and India enter their exact buy price, sell price, quantity and broker commission to see line-by-line net profit, required breakeven move and annual fee drag.
How costs differ by market
US stocks and ETFs. Many US brokers charge no commission on online stock trades; others charge per share or per order. Sales also carry small regulatory charges (the SEC Section 31 fee and the FINRA trading activity fee) whose rates are reset from time to time, so check your broker’s current schedule and enter it as a % on the sell value if you want it included. The preset starts at zero for all of these.
UK shares. Buying shares in most UK-incorporated companies electronically attracts Stamp Duty Reserve Tax of 0.5% of the price you pay. It applies to the purchase, not the sale, and some securities (for example most ETFs and shares on growth markets such as AIM) are exempt. The preset puts 0.5% on the buy side; set it to zero for an exempt security. Add your broker’s dealing charge as the commission.
EU shares. Some EU countries charge a financial transaction tax on purchases of large domestic companies (France and Italy, for example), and brokers charge per order. Enter the rate that applies to your share on the buy side.
Forex. The main cost is the spread, plus a commission per lot on some account types. Enter the commission per order and, if you want, the spread as a % of value.
Crypto. Exchanges charge a percentage of each trade’s value, with lower maker and higher taker rates. The preset uses 0.10% on each side as a round, editable starting point.
For Indian trades, the brokerage calculator lists every statutory charge line by line, including STT, exchange fees, stamp duty, the SEBI fee and GST.
Worked example
Buy 200 shares of a UK company at £5.00 and sell at £5.40, paying £6 per deal. Buy value £1,000, sell value £1,080, so the gross profit is £80. Stamp duty is 0.5% of £1,000 = £5 and dealing costs are £12, so you keep £63. To break even after costs you need to sell at about £5.09: (£1,000 + £5 + £12) ÷ 200.
Frequently asked questions
Why are the regulatory and commission fields editable?
Broker fee plans and regulatory assessment rates change over time and vary by account tier. Making every fee editable ensures you never rely on a hard-coded guess.
How is the breakeven move calculated?
Breakeven move equals total round-trip costs divided by your trade quantity. It tells you how much the price must move in your favor before net profit reaches zero.
What is annual fee drag?
Annual fee drag multiplies your single-trade round-trip cost by your monthly trade frequency times 12 months, showing how much capital active turnover consumes over a full year.
