Tip and bill split calculator
Splitting a restaurant bill fairly gets complicated fast with tax, tip, and an uneven number of people. This page covers the calculation logic before you use the calculator.
The basic split calculation
Add tax and tip to the subtotal first, then divide the total by the number of people—dividing the subtotal alone and adding tip separately per person can introduce rounding errors across a group.
Handling uneven splits
If people ordered very different amounts, consider splitting by what each person actually ordered instead of an even split—tally each person's items, then apply proportional tax and tip to their share.
Calculate with the tool
Enter the bill total, tip percentage, and number of people into the restaurant variant of the tip calculator to get an even per-person total instantly, including tax and tip.
Who this guide is for
Groups dining out or sharing travel costs who want fair splits without mental math.
