How the result is built
Commission = the greater of eligible gross × commission rate or the mini, multiplied by the salesperson’s split, plus their spiff. Pack reduces commissionable gross; it is not treated as an additional cash expense.
An example from the lot
On $3,000 front gross with $500 pack and a 25% rate, commission is $625 before minimums, splits, or spiffs.
