Split the bill and tip without the awkward maths
Working out a tip and dividing a bill between friends is exactly the kind of arithmetic nobody wants to do at the end of a meal. This calculator does it instantly: enter the bill, choose a tip percentage, and say how many people are splitting it, and everyone knows what they owe.
How to use the tip calculator
Enter the bill amount, the tip percentage you want to leave, and the number of people. You will see the tip amount, the new total, and the exact figure each person should contribute.
The simple maths behind it
The tip is the bill multiplied by the percentage: a 15% tip on $80 is $80 × 0.15 = $12, making the total $92. Split four ways that is $23 each. A quick mental shortcut is to find 10% first (move the decimal one place left) and adjust from there.
Tipping around the world
Tipping customs vary enormously. In the United States 18–20% is expected and anything under 15% is considered rude. In Australia 10–15% is appreciated but never required. In Japan tipping can even cause offence, and in the UK many restaurants add a service charge automatically — so always check the bill before adding more. When travelling, a quick look at local norms saves you from either under-tipping or paying twice.
