Tip & Bill Split Calculator
What is Tip Calculator?
Tip Calculator determines restaurant gratuity tips and splits the bill among multiple diners. Choose from standard tip presets (15%, 18%, 20%, 25%) or enter a custom percentage, with optional rounding to the nearest whole dollar.
Unlike legacy online utilities that upload sensitive media and documents to remote cloud storage, Shadow Toolkit executes this entire operation directly within your browser's local runtime. Your raw data never crosses the network.
