从Starlink星座2027年前的建设成本结构来看，可以提炼出三个关键判断：
地面基站是建设成本的绝对大头。地面基站100万个，单价3万美元/个，总成本30亿美元（图片中显示为3,000,000万美元，即30亿美元），占总建设成本约71%。Starlink的商业逻辑依赖于大规模用户终端的普及，地面基站（用户终端）的高投入反映了从“星座组网”向“用户覆盖”转换的规模化挑战。
组网卫星与发射构成第二大成本板块。组网卫星研制59.6亿美元（+试验卫星0.6亿美元）与发射49.8亿美元合计约110亿美元，占总成本约26%。单颗组网卫星成本50万美元、单次发射2,500万美元，Starlink通过自研火箭和卫星批量生产实现了业内最低的卫星制造与发射成本组合。
13年研发与运营成本合计约13.7亿美元。研发成本3.9亿美元、厂房与办公室费用5.7亿美元、人员成本3.6亿美元合计约13.2亿美元，占总成本约3%。2015-2027年间年均约1亿美元，在总计423亿美元的建设投入中占比相对较小，反映出SpaceX“以产品迭代替代长期预研”的高效研发模式。
