📖 Overview
Use this tool for accurate per-person dinner splits when tax and tip apply.
⚙️ How It Works
This calculates full bill including tax and tip, then divides by party size for per-person amount.
The Formula
Total = Subtotal × (1 + Tax%) × (1 + Tip%) | Per Person = Total ÷ Headcount
💡In the US, tip is typically applied to the pre-tax subtotal, though applying it post-tax is also common. Check local custom when dining out.
