📋 企业财务数据Business Financial Data —— 输入财务数据Enter financial data

📌 计算原理 📌 Calculation logic
动态分期利率 =(预估税额 ÷ 分期收入)× 100% Dynamic rate = (Estimated tax ÷ Period income) × 100%
其中预估税额基于本期实际利润年化计算,再乘以适用税率。 Estimated tax is annualised from actual period profit × applicable tax rate.

📖 动态PAYG计算逻辑说明Calculation Logic Explained

📐 核心公式Core formula
动态利率 =(预估税额 ÷ 分期收入)× 100% Rate = (Tax ÷ Income) × 100%
应付 = 当前分期收入 × 动态利率 Instalment = Period income × Rate
📊 预估税额Tax estimate
年化利润 × 适用税率 Annualised profit × Tax rate
年化利润 =(本期收入 - 本期支出)× 年化系数 Annualised profit = (Income − Expenses) × Multiplier

💡 使用场景示例: 💡 Example scenario:

一家小型餐饮公司(SBE,税率25%): Example: A small catering company (SBE, 25% tax rate):
  • 本期(月)收入:$120,000,支出:$85,000 → 月利润:$35,000Period (monthly) income: $120,000, expenses: $85,000 → profit: $35,000
  • 年化利润:$35,000 × 12 = $420,000Annualised profit: $35,000 × 12 = $420,000
  • 年化预估税额:$420,000 × 25% = $105,000Annual tax estimate: $420,000 × 25% = $105,000
  • 动态利率:$105,000 ÷($120,000 × 12)× 100% ≈ 7.29%Dynamic rate: $105,000 ÷ ($120,000 × 12) × 100% ≈ 7.29%
  • 本期应付:$120,000 × 7.29% ≈ $8,750This period: $120,000 × 7.29% ≈ $8,750
✅ 传统方式:基于去年$120,000利润 → 每季约$7,500 ✅ Traditional: based on last year $120,000 profit → ~$7,500/quarter
✅ 动态方式:淡季利润$35,000/月 → 付$8,750/月(更符合当前实际) ✅ Dynamic: $35,000/month profit → $8,750/month (reflects current reality)
