Equal split vs share split
Two ways of dividing an expense: equal divides evenly across all members; shares divides by weighted ratios.
Definition
Equal split divides an expense evenly across all attendees: a €100 dinner shared by 4 people = €25 each. Simple, fair when everyone consumed roughly the same, and the default for most quick splits. Share split (or 'shares mode') divides by weighted ratios that the group has agreed on: a €100 dinner with shares of 3:2:2:1 = €37.50, €25, €25, €12.50. Shares is used when group members have different reasons to pay different amounts - different incomes, different bedroom sizes, different consumption levels, or different ages (e.g., a family with kids might have shares of 2 per adult and 1 per child). The choice between equal and shares is one of the most common configuration questions when setting up a EvenRound group, and it should be agreed upon before logging the first expense to avoid retroactive changes.
Examples
- Roommates with different bedroom sizes: shares of 36:32:32 across €1,800 rent = €648, €576, €576.
- Couple with unequal incomes: shares of 60:40 on shared dinners = €60/€40 on a €100 bill.
- Family holiday with kids: shares of 2:2:2:1 (two parents, one kid) on grocery spend = parents pay 2/7 each, kid pays 1/7.
