💸 Free Bill & Group Expense Split Calculator
Splitting a group cost evenly is easy — and often unfair to whoever ordered a water and split fries, or booked the cheaper room. This calculator does it properly: assign each item to whoever actually owes it (or to a few people if it was shared), add tax and tip, and everyone's exact share comes out the other side, ready to paste into the group chat. Works for a restaurant bill, a trip's hotel and rideshare costs, shared rent and utilities, or a party/event's expenses — anything with a list of costs and a group of people splitting them unevenly.
Frequently Asked Questions
Does this split the bill evenly, or by what each person actually had?
By item — assign each item to whoever ordered it (or to several people if it was shared), and only those people split its cost. Nothing forces an even split unless everyone shares everything.
How is tax and tip divided?
Proportionally, based on each person's share of the pre-tax subtotal — someone who ordered more pays a proportionally larger share of the tax and tip, the same way an itemized restaurant bill would work it out.
Is anything about the bill saved or sent anywhere?
No — the whole calculation runs in your browser and disappears when you close the tab. Nothing is uploaded or stored.
Can I send the result straight to a group chat?
Yes — the results step has a one-tap "Copy Summary" button that formats each person's total as plain text, ready to paste into WhatsApp, iMessage, or Venmo.
Can I use this for a trip, shared rent, or an event — not just a restaurant bill?
Yes — "items" can be anything with a cost and a set of people covering it: a hotel room, a rideshare, groceries for a shared house, or decorations and tickets for a party. Add each one, assign who's paying for it, and the tax/tip fields are optional if they don't apply.
