total cost of ownership

When comparing suppliers, procurement teams should calculate the total cost of ownership, not just the purchase price.在比较供应商时，采购团队应计算总拥有成本，而不仅仅是采购价格。

Electric vehicles have a lower total cost of ownership than petrol cars when fuel savings are factored in.如果把燃料节省的费用计算在内，电动汽车的总拥有成本比汽油车更低。
