后续的费用用英语怎么说

在英语中，后续的费用通常被称为 "follow-up costs" 或 "additional costs." 这些费用通常是在初始费用之外的额外花费，可能是由于服务的延续或需要进行的额外工作导致的。

下面是一些例句：

"The initial cost of the repair was $100, but there were follow-up costs for parts and labor that brought the total to $200." (初始维修费用是100美元，但是需要花费额外的零件和人工费用，总费用达到了200美元。)

"The contract included a clause for additional costs in the event of any unforeseen circumstances." (合同中包含了一条有关意外情况可能产生的额外费用的条款。)

"The project ended up costing more than we expected due to additional costs that were incurred along the way." (由于沿途产生的额外费用，该项目最终的花费超出了我们的预期。)
