The formula this calculator uses
Net = (Exit - Entry) x Qty x Direction - (Entry x Qty + Exit x Qty) x Fee rate
- Entry
- Price the trade was opened at
- Exit
- Price the trade was closed at
- Qty
- Units traded
- Fee rate
- Commission charged on each side
How to check the result by hand
- 1
Find the price move
Subtract the entry from the exit for a long, or the other way round for a short.
- 2
Multiply by the quantity
The price move times the number of units gives the gross profit.
- 3
Work out the fees
Apply the fee rate to the sum of the entry notional and the exit notional.
- 4
Subtract to get net profit
Take the fees off the gross profit to reach the net result.
- 5
Divide by capital for the return
The net profit divided by the entry notional is the return on capital.
