📖 Overview
Use this calculator to avoid guesswork on service tipping amounts.
⚙️ How It Works
This calculates gratuity from bill amount and tip percentage, then returns both tip and total bill.
The Formula
Tip = Bill × (Rate ÷ 100) | Total = Bill + Tip
💡In the US, 18–20% is standard for sit-down restaurants. 15% is acceptable for counter service; 25–30% for exceptional service.
