计算原理
Base labour = hourly rate × estimated hours. The revisions buffer adds extra hours (rate × hours × buffer%). Expenses are added as a flat % of base labour. Profit margin is applied to the running subtotal (labour + revisions + expenses).
Final quote = (base + revisions + expenses) × (1 + profit%). Effective rate = quote ÷ estimated hours, so you can see what you're really earning per hour after buffers.
