How to organize a tanda or savings circle

Start with people who already trust each other

A tanda has no bank, contract or collateral behind it, so the members themselves are the security. In its 2006 discussion paper on savings circles, the Federal Reserve Bank of Philadelphia explains that organizers recruit people from their own social network whom they can depend on to pay, and that members join only if they see the organizer as credible and trustworthy.

The same pattern shows up in a 2023 University of Minnesota study of Mexican American tanda members, published in the Journal of Family and Economic Issues. Tandas were usually made up of relatives, friends and co-workers, strangers were rare, and newcomers typically got in because someone already in the group vouched for them. One participant described the rule in her circle: two people from the same family have to be there, or one of them has to know more people in the circle.

Some traditions handle newcomers by giving them later turns. The Philadelphia Fed paper, citing research by Bouman and Harteveld, notes that new members may receive the pot in the last rounds and move up once they have shown they pay reliably. As for size, the same paper puts a typical circle at 10 to 12 people. Every extra member adds a round and makes the whole cycle longer.

Agree on the amount, the schedule and the number of rounds

Before anyone pays, settle the basics. A September 2026 Imagen Radio report on guidance from CONDUSEF, Mexico's financial consumer protection agency, lists what participants should know up front: who will manage the money, how much each person contributes, for how long, what the order of turns is, and what happens if someone stops paying. Those five questions make a good agenda for the first meeting.

Schedules tend to follow pay dates. Most tandas in Mexico line up with the quincena, the pay days on the 15th and 30th of the month, and others run weekly, according to a guide to organizing a tanda published by Eje Central. Indonesian Wikipedia describes arisan members paying monthly as agreed. Wikipedia's ROSCA article notes that meetings often coincide with harvests or pay dates, when members have cash on hand.

The number of rounds normally equals the number of members, so each person receives once. Wikipedia's ROSCA article notes that a member can take more than one slot, and each slot is one payout, so the circle runs longer and that member receives more than once. The amount matters less than whether every member can keep paying it through the last round, since the members whose turns come late depend on those payments.

Decide the payout order before the first payment

Settle the order before any money moves. Wikipedia's ROSCA article describes slots being drawn and agreed before contributions start, and in the Minnesota study the order was fixed before the tanda began. Circles tend to use one of four methods.

Agreement. Members discuss who needs the money when. In the Minnesota study, people with urgent needs took the first spots and people saving for a planned purchase asked for the last numbers. The Philadelphia Fed paper notes that the organizer normally takes the first pot in return for the administrative work.

One draw at the start. Everyone draws a number once and the whole order is fixed. Korea's National Institute of Korean History describes fixed-order gye in which the organizer either handed out the numbers or had members draw lots, and Eje Central's guide describes a common mix in Mexico: the organizer takes the number that suits their plans and the rest are drawn.

A draw each round, or bidding. In a per-round draw, the recipient is picked by lottery from the members who have not yet received, as in the Indonesian arisan and the Korean chucheom-gye. In bidding circles, which the Philadelphia Fed paper describes in detail, members still waiting bid for the pot and the winning bid comes off their contributions. Bidding changes what each person pays in total, so walk the group through a worked example before anyone agrees to it.

Write the rules down, including missed payments

Informal does not have to mean unwritten. South Africa's National Stokvel Association, NASASA, a self-regulatory body authorised by the South African Reserve Bank, publishes a template constitution for savings clubs. It covers the contribution per meeting, how often the group meets, what members receive, what happens to money owed to a member who dies, how the club closes, and how the rules can be changed, which in the template takes a two-thirds vote announced 60 days ahead.

For a tanda, the most important written rule is what happens when someone does not pay. No financial institution guarantees the contributions, as the Imagen Radio report on CONDUSEF guidance points out, and in practice the organizer often ends up covering the gap. The Philadelphia Fed paper describes organizers being expected to keep collections on track "even if it means assuming the payments of a defaulting member," and Eje Central's guide states that the organizer is responsible for defaults and has to resolve them one way or another. Decide in advance how late a payment can be, who covers a missed one, and how a member who leaves is replaced.

Two more rules head off disputes. The first is whether the organizer gets anything for the work. The Imagen Radio report notes that, depending on what the group agrees, an organizer may take one of the first turns or the last one, or receive a commission for coordinating. The second is what happens if the tanda has to pause. In the Minnesota study, one group agreed to pause during Covid-19 when several members lost work, and a member who had already paid in was left wondering whether it would restart.

This guide describes how savings circles are commonly organized. It is not legal or financial advice. For questions about your own situation, talk to a qualified adviser or your country's financial consumer protection agency.

Keep a record of every round

When a circle meets in person, record keeping can be minimal. Wikipedia's ROSCA article notes that every member sees every transaction at the meeting, so many circles keep nothing more than a rough list of slots. That changes when payments go by transfer. In the Minnesota study, some tandas had members send their share straight to the recipient through mobile banking apps, and then nobody sees the whole round unless someone writes it down.

The NASASA template gives this job to named roles: a secretary keeps the membership register and minutes, and a treasurer keeps an accurate account of the group's money. A tanda rarely needs officers, but the organizer can keep the same kind of record. For each round, note the date, who paid in full, who paid part and how much, who received the pot, and how that person was chosen. Share a short summary with the group once the round closes.

A notebook or a shared spreadsheet can do this. Tandalo is a phone app built for the same job: the organizer keeps a table of members and rounds, marks each payment as full, partial or not recorded yet, and either sets the order up front or draws each round by shaking the phone. Each draw keeps its seed so anyone can re-run it later, and each closed round becomes a receipt card to share in the group chat. It is only a ledger and never holds or moves the money.

Common organizer mistakes

Letting in people nobody can vouch for. Strangers were rare in the tandas of the Minnesota study, and the Philadelphia Fed paper notes that a member can take their turn and move away. Invitations from strangers online are a separate warning sign. The US Federal Trade Commission warns that games like the Giving Circle and Blessing Loom, which promise $800 for $100, are pyramid schemes that depend on recruiting new people.

Changing the order without telling anyone. Swaps are normal, and Wikipedia's ROSCA article notes that members can trade slots by mutual agreement as long as the organizer hears about it before the payment. Tell the whole group too, since the Minnesota study describes members picking their spot to match a planned expense.

Covering missed payments without saying so. Organizers often absorb a default, as both the Philadelphia Fed paper and the Minnesota study describe. If that is the plan, put it in the written rules so the group knows whose money is keeping a round whole and for how long.

Relying on memory. A tanda of ten monthly rounds runs for most of a year, and details like who paid part of round three are easy to lose. A dated record of payments and recipients, shared after each round, gives everyone the same version of events.
