About the Split Bill Calculator
An even split is easy but unfair when one person had a salad and another had steak and two cocktails. This calculator takes each person's items, adds a share of anything ordered for the table, then divides tax and tip in proportion to what each person actually spent — the method most people agree is fair once it is spelled out.
How to use the Split Bill Calculator
- Add each person and type their item prices separated by commas.
- Enter anything shared by the table as a single total.
- Set the tax and tip percentages.
- Read the table to see exactly what each person owes.
Why use this tool?
Proportional tax and tip
Someone with 30% of the order pays 30% of the tax and tip — not an equal slice.
Shared items handled
Starters and table drinks are split evenly, separate from individual orders.
No currency assumed
Works with any currency; enter plain numbers and read plain numbers back.
Frequently asked questions
Should tip be split evenly or by order size?
By order size is the fairer default, since a larger order takes more service. Some groups prefer an even tip split — the shared-items field lets you approximate that.
Do I tip before or after tax?
Etiquette favours the pre-tax subtotal, but most people tip on the total shown. On a $50 meal the difference is under a dollar.
What about someone who only had water?
Enter no items for them. They will owe zero unless there is a shared total, in which case they pay only their share of that.
