使用说明
- 环境配置
在MT5终端中启用WebRequest功能
添加API域名到允许列表：https://api.exchangerate-api.com
- 参数设置
参数 说明 示例
IncomeAmount 收入金额 5000
IncomeCurrency 收入币种 USD
TaxCurrency 计税币种 CNY
TaxRate 税率(%) 10
Deduction 免征额 5000 - 运行效果
text
===== 个人所得税计算器 =====
收入金额: 5000.00 USD
计税币种: CNY
税率: 10.00%
免征额: 5000.00 CNY
成功获取汇率: 1 USD = 7.25 CNY
折算后收入: 36250.00 CNY
应纳税所得额: 31250.00 CNY
应缴个人所得税: 3125.00 CNY
税后收入: 33125.00 CNY
===== 计算完成 =====
技术要点解析
- WebRequest网络请求
使用HTTP GET方法获取实时汇率
JSON响应解析提取目标币种汇率
超时和错误处理机制
- 汇率API集成
支持任意币种对换算
自动处理API响应格式
网络异常时的降级策略
- 税务计算逻辑
应纳税所得额 = 收入 - 免征额
个人所得税 = 应纳税所得额 × 税率
支持负收入自动归零处理
