How Bill Splitting Works
Equal split: Each person pays Total / Number of people
Percentage split: Each person pays Total × their share %

Frequently Asked Questions
Should tip be calculated on pre-tax or post-tax amount?
Tip is traditionally calculated on the pre-tax subtotal, since the server doesn't provide the tax service. However, tipping on the total (pre-tax + tax) is common in practice and the difference is small. This calculator lets you choose the base for tip calculation.
How do I handle unequal splitting?
Use the custom split mode to assign percentages per person. For example, if Person A ordered $40 in food and Person B ordered $20, A pays 67% and B pays 33% of the total. Alternatively, many groups find it easiest to split shared items equally and have each person pay their own individual orders separately.
Is it rude to split the bill at a restaurant?
In most US restaurants, asking for separate checks or splitting a bill is common and accepted. It is considerate to let your server know at the start of the meal rather than at the end. In some countries and upscale restaurants, splitting may be less welcome — check local customs when traveling.
