Bill Splitting Calculators
Free tools for working out who owes what. For when an even split isn't fair, when the bill has fifteen items on it, or when a whole trip's worth of costs needs untangling. No signup required for any of them.
This calculator works out what each spot in the Airbnb should cost, weighted by the three things that matter most. And it gives you a message you can paste straight into the group chat so you can decide who goes where before booking.
Open the Airbnb calculator →Splitting rent evenly only works when the bedrooms are equal. This weights each room by size and bathroom, splits the common space evenly by headcount, and gives you a monthly figure per person to send the group before anyone signs.

If everyone is paying for the same thing, split it evenly and stop. The arithmetic is rarely worth the conversation. Reach for a calculator when people got materially different things: one room has an ensuite and another has bunk beds, or half the table drank and half didn't.
Some splits don't need one. A restaurant bill already lists what everyone had, so splitting a bill automatically by item from scanning a photo on Tabster beats typing it into a form. And a whole trip's worth of costs isn't one sum to divide. That that warrants a trip on Tabster that collects scanned receipts and other expenses as they happen, so you can easily divvy up at the end of the trip.
