How do you split a bill evenly between friends?

Add the subtotal, tip, and tax together to get the grand total, then divide by the number of people. The Squarekin calculator does this for you and flags any sub-cent remainder so one person isn't quietly overpaying.

Is the bill split calculator free?

Yes. No signup, no ads, no email capture. Squarekin runs it as a free public tool. If you want to track the split across multiple expenses or settle later, you can save it as a Squarekin trip in one tap.

Does it support tip and tax?

Both. Tip and tax slide independently from 0% to 30% / 25%. Common presets (15, 18, 20 for tip; 7, 10 for tax) are one tap away.

What currencies does it support?

USD, EUR, GBP, INR, CAD, AUD, and JPY out of the box. The selector is next to the bill total. The chosen currency is preserved in the shared URL.

Can I share the result with friends?

Yes. Tap Share to copy a link that opens the calculator pre-filled with the same total, people, tip, and tax. Works in iMessage, Slack, Discord, WhatsApp, anywhere.

How is this different from Splitwise?

This calculator does one thing — split a single bill — and needs no signup. Squarekin (the full app) tracks groups of expenses over time, supports recurring bills, handles multi-currency settlements, and remembers who owes whom across trips. Most people start with the calculator and graduate to the app when their splits stop fitting on one screen.

FAQ

How do you split a bill evenly?

Add subtotal + tip + tax for the grand total, then divide by the number of people. This calculator does the math in integer cents so the per-person totals always sum back to the grand total — no quiet rounding loss.

Is the calculator free?

Yes — free, no signup, no email capture, no ads. Squarekin runs it as a public tool.

Can I split unevenly (some people pay more)?

Not in this free calculator — it's a one-shot equal splitter. For per-item or per-person-percentage splits, save the bill as a Squarekin trip and use the full splitter (equal, exact, percent, shares, or per-family modes).

Does it work offline?

Yes after the first page load — the calculator is pure JavaScript and doesn't need the network to compute.

Will I get spam if I save the split as a trip?

No. Squarekin doesn't sell or rent your email. Signup is one tap and you can delete the account any time from Settings.

Going beyond one bill?

Track shared expenses across a trip, a household, or a year.

Squarekin remembers who paid, who owes whom, and settles multi-currency totals in one tap. Free for groups of any size.
