One obvious savings with consultants is the avoidance of often hefty recruiting fees. What may be less obvious, though, is that each recruiting fee paid drives up the real cost of all employees. Since recruiting costs are including in overhead expenses, every recruiting expense that your company incurs increases your overhead costs, which in turn raises your overhead rate multiplier, which in turns drives up the effective cost of each and every one of your employees (i.e., since the overhead multiplier is used in calculating every employee’s real cost, the higher that multiplier is, the higher each employee’s real cost ends up being).
