T = 缴费基数 × 费率

Social Security Contribution Calculator

Compute social security contributions: T = contribution base × rate.

📐 计算公式
社保费用测算(本页代码口径):社保费=缴费基数×费率(元,费率为小数);联动量:用工总成本=基数+社保费(元)、社保费率(%)=社保费÷max(基数,10⁻⁹)×100、基数与社保费之差=基数−社保费(元)。校验:无强校验,空值按 0 兜底。判据:无固定分级,费率取 0~1 小数,单位与个人部分须分别按各自费率套用。

输入缴费基数与社保综合费率,求社保费。

📚 深度解析:社会保险费

💡 常见使用场景

基数 1 万、费率 18%
社保费 T = 10000 × 0.18 = 1,800 元;费率升到 20% 则为 2,000 元。
超过上限
若基数上限 3 万、实际工资 5 万,则按 3 万计,费 = 30000 × 0.18 = 5,400 元。
