How to split a bill when a couple is in the group

Split a bill with a couple in the group by counting heads for the things people consume (food, drinks, activities) and counting rooms or cars for the things people occupy (a hotel room, a seat in the car). In Zeroed that is a shares split: give the couple two shares on the dinner line and one share on the accommodation line if they took a single room. Treating the couple as one unit everywhere is the usual mistake and quietly overcharges the singles.

Why do couples break equal splits?

Because a couple is two mouths and one room. Split a dinner per head and it is fine. Split accommodation per head and the couple in one double pays the same as two singles in two rooms, which is wrong in their favour. Split everything per couple and the singles subsidise everyone. The fix is to split each line by the thing that line actually measures.

The rule of thumb

Cost	Split by	Couple counts as
Food and drinks	heads	2
Activities and tickets	heads	2
Hotel or Airbnb rooms	rooms	1 (if sharing a room)
Car hire and fuel	heads	2
Group gift	the group’s call	1 or 2, decided up front

How to do it in a ledger

Add the couple as two people. On each line, use the split that fits: equal among everyone for dinner; shares on accommodation (1 share per room, so both halves of the couple get half a share each, or just leave one of them off the line). Zeroed’s shares split lets you type any whole-number weight per person.

The gift question

For a group gift, ask the couple whether they want to count as one contribution or two. Either is fine. Asking is what keeps it fair.
