Frequently Asked Questions

Advanced How do you split a vacation fairly when people have different budgets?
Use proportional or selective splitting: assign lodging by room (couples share a room cost equally, singles pay their own). For activities, only those who participate pay. Meals can be split equally or itemized. This calculator handles all these scenarios — just select the participants for each expense.
Basics What is the settlement algorithm?
The calculator computes each person's net balance — total owed minus what they've already covered. It then greedily pairs the largest creditor with the largest debtor until all debts cancel out. This minimizes the total number of transactions needed to settle the trip.
Advanced How should couples split vacation costs?
Couples typically share one room and appear as two separate people in the group. For lodging, select both members of the couple and the cost splits equally between them. For couple-only activities, select just the two of them. For group dinners, select everyone.
Advanced What if someone paid for a group expense upfront?
Add the expense normally with the total cost and all participants. The Settlement tab will show who owes money back to the group. You can note "paid by Alice" in the description so everyone knows she fronted it — the settlement instructions will show others paying Alice directly.
