How the Tip Calculator Works – Detailed Formula & Explanation

Our tip calculator uses simple, transparent math to give you instant results. Here's exactly how it works:

Tip Amount = Bill Amount × (Tip Percentage ÷ 100)
Example: For a $100 bill at 18% tip → $100 × 0.18 = $18.00
Total Bill = Bill Amount + Tip Amount
$100 + $18 = $118.00
If splitting among people:
Amount Per Person = Total Bill ÷ Number of People
$118 ÷ 2 people = $59.00 each

This calculator updates in real-time as you type or adjust the slider – no need to press any button. It's designed to be fast and intuitive, whether you're at a restaurant or splitting delivery costs.
