Costs, Spreads & FeesAll-In CostEffective Cost
Total Cost of Trading
The complete cost of a trade or account, combining spread, commission, swap, slippage and non-trading fees.
What Total Cost of Trading means
The total cost of trading is the sum of everything a position surrenders to the broker and the market. The trading components are the spread paid on entry and exit, any commission on each side, swap or financing for every night held, and realised slippage relative to the intended price. The non-trading components are inactivity charges, withdrawal fees and currency conversion on results and transfers. Only the sum is comparable between brokers, because the same total can be packaged as a wide spread, as a raw spread plus commission, or as a mixture.
The weighting of those components depends entirely on holding period and turnover. For an intraday strategy the spread, commission and slippage dominate and swap is irrelevant; for a position trade held for weeks, financing can dwarf the entry cost. Expressing everything as a pip equivalent per round turn, then comparing it with the strategy's average gross profit per trade, gives a usable measure: a system earning ten pips gross that pays two pips all in is giving up a fifth of its edge before anything goes wrong.
Two components are routinely omitted from broker comparisons and are often the largest. Slippage is a real cost that does not appear in any fee schedule and can only be measured from a fill history, and currency conversion on results in a non-base currency is applied to gross turnover rather than net profit. Advertised typical spreads, being averages taken across all hours, are the least reliable single number on which to base a choice.
Worked example
One standard lot of EUR/USD held four nights might cost USD 6 of spread, USD 7 commission, USD 29 of swap and USD 3 of slippage, giving roughly USD 45 in total, or about 4.5 pips.
