Three singles and a couple rent a villa. Is that four shares or five? The couple shares one room, but they're two mouths at dinner. Groups fall out over this because they never say which rule they're using. Here are the rules, and when each is fair.
Rule 1: per person, always
Every bill is divided by the number of people. The couple counts as two. Simple, and clearly right for food, tickets, fuel and anything consumed per head.
It feels wrong for accommodation when the couple shares a room and the singles each have one: the couple pays twice as much for the same room.
Rule 2: per room for accommodation, per person for everything else
This is what most groups actually want. The villa or hotel cost is split by rooms (or by beds, if a single is in a twin with another single). Everything else is per person.
Example: villa ₹20,000 a night, four rooms: three singles, one couple. Per room = ₹5,000 each, so the couple pays ₹5,000 total, ₹2,500 each. Dinner for five people: ₹2,500, so ₹500 each including both halves of the couple.
Rule 3: per household
The couple is treated as one unit for everything. Fair when the couple genuinely has one budget and the group is small and relaxed about it. Unfair on big meal bills if the couple eats and drinks like two people, which they do.
Making it work in Ezysplit
Add every individual as a member, including both halves of the couple. Then:
- Per-person bills (meals, activities): add normally.
- Per-room bills: enter the accommodation as separate expenses, one per room. For a single's room, exclude everyone except that person. For the couple's room, exclude everyone except the two of them, so they each get half of their room's cost.
That sounds like a lot of exclusions for a four-room villa but it is four expenses once, and then every balance is right for the whole trip. The trip checklist has more on logging as you go.
Couples settling with each other
If a couple shares money, they often don't care which of them pays. Ezysplit still shows them separately, which is correct: it means the group's maths doesn't depend on the couple's private arrangement. They can pay from one account and ignore the line between them.
Say it before the trip
"Rooms by room, everything else per person" is a single sentence. Put it in the group chat when the booking is made. The couple will usually propose it themselves if someone opens the door.
