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.

How to split bills fairly between roommates?

For roommates with similar income, an equal split works best — just click "Split evenly". If one roommate has a larger room or earns significantly more, consider a proportional split like 60/40 or 55/45 to keep things fair.

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 as a split rent calculator?

Absolutely. Enter your total rent as a bill, set each person's percentage based on room size or income, and instantly see what each person should pay. You can add utilities and other shared expenses too.

Can I use this for co-parenting expenses?

Yes. 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 really free?

Yes, completely free with no sign-up required. For ongoing shared expense tracking with automatic reminders and settlement history, check out billplit Pro.

Can I split bills online without downloading an app?

Yes — this free bill splitter works entirely in your browser. No app download, no registration, no personal data collected. Just open the page and start splitting.

How do I split bills with different percentages for each person?

Enter the percentage each person should pay in the "%" field next to their name. For example, if three people share a bill at 50%, 30%, and 20%, enter those percentages. The results update instantly.

What types of bills can I split with this tool?

Any shared expense — rent, utilities, groceries, restaurant bills, travel costs, vet bills, childcare expenses, subscriptions, and more. There's no limit on the number of bills you can add.
