Frequently asked questions
How do you split a bill including a tip?
Use bill × (1 + tip percentage ÷ 100) ÷ people. Enter a tip of 0 if no tip applies.
Why can the split amounts exceed the bill?
Each amount is rounded up to the smallest currency unit. Reduce one person’s payment by the displayed surplus to match the total.
Method and references
