Bill Splitter is a free group expense splitter that runs entirely in your browser with nothing uploaded. Each split is its own group saved on your device like a notepad. Add people, log expenses shared equally or by exact amounts, percentages or shares, record settle-up payments, and it shows everyone's balance and the simplest way to settle up. Keep multiple groups and back them up by saving and importing JSON.

Frequently asked questions

Where is my data saved, and is it private?

Only in this browser on your device, using local storage, like a notepad. Nothing is uploaded, so your splits stay private and are there when you return. Clearing your browser cache or site data will remove them, so use Save for a backup.

What split methods can I use?

Equally, by exact amounts, by percentages, or by shares. Choose the method when adding an expense and enter each person's part. The tool warns you if percentages do not add up to 100 or exact amounts do not match the total.

What does Settle up do?

It records a payment from one person to another, which updates the balances. Use it when someone actually pays back what they owe, so the figures stay accurate over time.

Can I keep several groups and back them up?

Yes. Use the plus button to add as many splits as you like and switch between them in the sidebar. Save downloads everything as a JSON backup, and Import loads it again, replacing or merging, to move between devices.

Does it work on a phone?

Yes. The layout adjusts to small screens, with the splits list above and the active split below, and the forms stack so you can add people and expenses comfortably on mobile.
