T = 收益 × 优惠税率

Effective Capital Gains Tax Calculator

Compute tax on capital gains using a preferential rate: T = gain × preferential rate.

📐 计算公式
资本利得应纳税额 T = 资本利得 g × 税率 r(r 按小数输入,如 0.2 即 20%),T 保留 2 位小数;税后利得 = g − T;有效税率 = T ÷ max(g, 10⁻⁹) × 100%;税率倒数 = 1 ÷ max(r, 10⁻¹²)。校验:无强校验,非数输入按 0 兜底。判据:g >0 时有效税率恒等于 r × 100%,税后利得随税率线性递减,倒数卡仅作口径对照。

输入资本收益与适用优惠税率,求资本利得税。

📚 深度解析:资本利得税(按利得计征)

💡 常见使用场景

利得 10 万、税率 10%
资本利得税 T = 100000 × 0.10 = 10,000 元;利得翻倍到 20 万则税为 2 万元。
负利得不缴税
若利得为 −30000(亏损),多数规则下税额取 max(0, 利得×r)=0,亏损可结转抵减未来利得。

❓ 常见问题(FAQ)

资本利得税与所得税有何区别?
资本利得税专门对资产增值(买卖差价)征收,通常税率或免税规则与工薪所得税不同。
亏损如何处理?
亏损一般当年不缴税,并可在规定年限内结转,抵减今后实现的利得。
