This is true, however, if the selling division has sufficient capacity to produce the entire order and would not have to give up some of its regular sales. In cases where capacity constraints force the division to either transfer an item internally or sell it externally- that is, it cannot produce enough to do both, then the selling division would expect to be compensated for the contribution margin on those lost sales. In general, if the transfer has no effect on fixed costs, then from the selling division’s standpoint, the transfer price must cover both the variable cost of producing the transferred units and any opportunity costs from lost sales.
