Uneven Airbnb Split Calculator

Each person gets a share equal to their nights stayed multiplied by their room's quality weight (master 1.5, private bedroom 1.0, shared bed 0.7, couch 0.5).

The total lodging cost is divided across everyone's weighted nights, so someone who stayed half the trip in a worse bed pays a fraction of what the master-suiters pay.

Couples sharing one bedroom each enter their own row with the same room type — the math handles it automatically, and they can settle the intra-couple split themselves.

The breakdown is written as a sentence, not a spreadsheet, so you can copy it into the group chat and the argument ends before it starts.

A bachelorette or group house where some people fly in late or leave early and shouldn't pay for the nights they weren't there.

Any Airbnb where the bedrooms are obviously unequal — the master with the en-suite versus the pullout in the living room.

When one person booked the house and fronted the money and needs a defensible, copy-pasteable split to send the group.

Before the deposit, not after — agreeing on the split method up front is what stops the last-morning resentment.

Splitting evenly by head. The person on the couch for two nights quietly subsidizes the couple in the master for five — and they notice.

Forgetting the person who booked and fronted the money. They're owed the difference, not a share; settle it explicitly so the Venmo chase doesn't run a year.

Letting the bride's coverage be implicit. If the group is covering one person, say so in the chat, in one sentence, before anyone pays — ambiguity is where the resentment lives.

Weighting only by room and ignoring nights. A master for two nights can cost less than a private room for five; nights × weight is the fair unit.
