实际税率计算器

Effective Tax Rate Calculator

📐 计算公式
实际税率 ETR = 总税额 ÷ 税前所得 × 100(%);联动卡:税后所得 = 税前 − 税额、实际税率小数 = 税额 ÷ 税前、税前/税额倍数 = 税前 ÷ (税额||1)。校验:两项非空守卫,税前所得为分母、=0 报错,全 0 报错。判据:无固定分级,ETR 越高综合税负越重,等于 0 即免税。

综合衡量实际承担的税负水平。

📚 深度解析:实际税率(综合有效税率)

💡 常见使用场景

税额 25 万、税前利润 100 万
实际税率 = 250000 / 1000000 × 100% = 25%;税后所得 = 1,000,000 − 250,000 = 750,000 元。
享受优惠后
若因减免税额降到 15 万、税前利润不变,则 ETR=15%,比法定 25% 低 10 个百分点。

❓ 常见问题(FAQ)

实际税率与法定税率为何不同?
法定税率是名义档,实际税率受优惠、扣除、亏损结转等影响,通常低于法定税率。
ETR 越低越好吗?
不一定,过低的 ETR 可能来自一次性减免或暂时性差异,需结合可持续性判断。
