How to Calculate a Tip and Split a Bill
Splitting the restaurant bill and calculating the right tip shouldn't require mental math gymnastics. This free tip calculator handles any bill amount, any tip percentage, and any number of diners — giving you exact amounts in seconds.
The Simple Tip Formula
// Tip Calculation
Tip = Bill × Tip% ÷ 100
Total = Bill + Tip
Per Person = Total ÷ Number of People

Tipping Etiquette Tips
- Always tip in cash when possible — servers keep 100% immediately
- For large groups (6+), an automatic 18–20% gratuity is often added
- For exceptional service, add a personal note with your tip
- On international travel, research local customs — tipping is not universal
In the US, most restaurant servers earn a tipped minimum wage of $2.13/hour federally (higher in some states), making tips a critical part of their income.
