Frequently asked questions
How do I split a bill unequally?
Set each person's percentage to whatever share they should pay — it doesn't have to be equal. The percentages just need to add up to 100%. For example, one person could pay 70% and another 30%.
Can I split a bill between more than 2 people?
Yes — click "Add person" to add as many people as you need. The tool will automatically recalculate everyone's share as you add or remove people.
What is the best way to split shared bills fairly?
For equal splits, give everyone the same percentage. For co-parents or situations where one person earns more, use a custom percentage split like 60/40 or 70/30 to reflect what feels fair.
Can I use this for co-parenting expenses?
Absolutely. Many co-parents use a court-agreed percentage (e.g. 60/40) for shared child expenses. Enter your agreed split, add your bills for the month, and see exactly what each parent owes.
Is this bill splitter free?
Yes, completely free with no sign-up required. For ongoing shared expense tracking with reminders and settlement history, check out billplit Pro.
