How it works
Entry and exit fees use their own notionals, which may differ as price changes. Maker and taker labels describe execution; they do not supply fee rates automatically.
The formula
Keep currency, units and time periods consistent. Percentage inputs use percentage points (enter 5 for 5%). Results are rounded only for display; tiny nonzero values may use scientific notation. Undefined ratios are shown as unavailable.
$5,000 entry and $5,500 exit, each at 0.1%, cost $5 + $5.50 = $10.50. On $500 gross profit, net profit is $489.50 and fee drag is 2.10%.
Calculation method
Repeated-trade totals assume identical notionals and rates on every round trip. Funding and borrow costs remain separate from core trading fees. Taxes are excluded.
Interpretation
Fee drag divides fees by positive gross profit. When gross profit is zero or negative, that percentage has no useful positive-profit denominator and is displayed as not available.

Frequently asked questions
Why do fees apply on both entry and exit?
A completed trade often has two charged transactions. The exit notional can differ from entry notional, so apply the appropriate fee rate to each side.
