What is a arisan?
An arisan is an Indonesian rotating savings gathering: members contribute a fixed amount at each meeting and one name is drawn by lot ("dikocok" — shaken from a tin or bottle) to take the whole pool. Each member wins exactly once per cycle, so the draw only includes names that have not yet collected.
Also known as: arisan keluarga (family) · arisan RT (neighborhood) · arisan kantor (office). It is one of 70+ regional forms of the ROSCA — rotating savings and credit association — used by an estimated 2+ billion people worldwide.
How a arisan works
- A group — commonly an extended family, a neighborhood unit (RT/RW), coworkers or a religious study group — agrees on a contribution and meeting rhythm, usually monthly.
- Meetings rotate between members’ homes; the host typically provides food.
- At each meeting, contributions are pooled and a name is drawn from those who have not yet won.
- The winner takes the pool and is removed from future draws; the cycle ends when everyone has won once.
Role and reach
Arisan is as much a social institution as a financial one — the gathering, the meal and the network matter as much as the money. It spans all classes: village arisan measured in thousands of rupiah, office arisan in salaries, and high-end arisan among wealthy urban circles.
Because the winner is drawn by lot, an arisan is also a commitment device: you keep paying after you win because the people across the table are your family, neighbors or colleagues. Distance weakens that enforcement — which is why arisan rarely survives between strangers.
How it differs from other ROSCAs
- The payout order is random (a fresh lottery each round), not fixed and not priced — someone with an urgent need can only hope.
- Social attendance is near-mandatory; the circle is an event, not just a ledger.
- Trust is enforced by kinship and neighborhood standing rather than deposits or ratings.
The digital version
ROSCASH replaces the lottery with a discount auction — need the pool now? Bid for it; everyone who waits gets paid for waiting — and replaces kinship enforcement with deposits and an on-platform reputation score.
The mechanics are documented in the circle guide, and the honest questions — custody, "is this a pyramid?", where returns come from — in the FAQ.
