The accounting relationship
For an explicitly defined sample, net outcome equals gross outcome minus included costs. A report needs to state which charges are included and avoid subtracting costs already embedded in the gross figure.
A worked example
An example gross outcome of +150 units with 90 units of recorded commissions produces +60 units after those commissions. Missing funding, conversion or other costs would change the result. This is not a customer record or an estimate of savings.
Limits of the comparison
Cost categories differ across instruments and venues. A fee total alone does not establish what trading activity should change or which provider is appropriate. The showcase makes no broker, product or tax recommendation.
