计费概述

本页目录：

计费方式
云数据库 PostgreSQL 提供如下两种计费模式：
计费模式
付费模式
适用场景
包年包月
预付费模式，即在新建实例时支付费用。
适合业务量较稳定的长期需求，费用较按量计费模式更为低廉，且购买时长越长，折扣越多。
按量计费
后付费模式，即先按需申请资源使用，在结算时会按您的实际资源使用量收取费用。
适合业务量有瞬间大幅波动的业务场景，用完可立即释放实例，节省成本。
计费公式
总费用 = 内存规格费用 + 硬盘费用 + 备份空间费用（超过赠送空间计费 ）+ 日志空间费用（目前免费） + 流量费用（目前免费）
计费项
计费项
说明
内存规格费用
在购买页选择的实例规格的费用，支持包年包月和按量计费阶梯价，价格请参见 产品定价。按量计费实行三阶梯价，用的越久，优惠越大：
第一阶梯 T1，0小时 ＜ T1 ≤ 96小时；第二阶梯 T2，96小时 ＜ T2 ≤ 360小时；第三阶梯 T3，T3 ＞ 360小时。
硬盘费用
在购买页选择的硬盘大小的费用，支持包年包月和按量计费价，价格请参见 产品定价。
备份空间费用
免费赠送实例购买容量100%，超过免费容量收费，价格请参考 备份空间收费说明。
日志空间费用
免费赠送实例容量的50%，超过免费容量部分，目前免费。
流量费用
实例往客户端发送的公网流量费用，目前免费。
