Tanda, susu, chama, tontine: the global guide to savings circles (ROSCAs)

One adult in four in Sub-Saharan Africa saves in a circle like this, and so do millions of families from Los Angeles to Manila. Here’s how it works, and how to run one without falling out.

  • A savings circle is a group where everyone pays in the same amount at regular intervals; each round, one member receives the whole pot, until everyone has received it once.
  • Economists call it a ROSCA (rotating savings and credit association). It goes by dozens of names: tanda, susu, chama, stokvel, esusu, paluwagan, hui, kye, chit fund, tontine…
  • According to the World Bank, 25% of adults in Sub-Saharan Africa saved using a savings club or a person outside the family in 2021.
  • Its value: getting a lump sum sooner than saving alone, without borrowing. The main risk: a member who stops paying after receiving the pot.
  • Written rules, a transparent payout order and tracking everyone can see prevent most disputes.

How a savings circle works

Six friends agree to contribute $100 a month for six months. Each month the pot is 6 × $100 = $600. In round one, Ama receives $600; in round two, Kofi; and so on until month six. By the end, everyone has paid in $600 and received $600.

  • has paid
  • hasn’t paid yet
Round 3: Maria receives the pot. Four members have already paid this month.

If nobody gains or loses money, why do it? Because the circle changes when you get the money. Economists Timothy Besley, Stephen Coate and Glenn Loury analysed this in the American Economic Review in 1993: for people without access to credit, a circle lets members buy a costly item earlier, on average, than saving alone. Only the last person in line gains nothing on timing. They actually lose a little: the money earns nothing during the cycle and inflation erodes it, a point Mexico’s financial consumer watchdog, Condusef, makes about tandas.

Savings circles around the world

Anthropologist Shirley Ardener wrote the classic comparative study of these associations in 1964. The same principle shows up on nearly every continent:

Bidding circles

In some circles (hui, Indian chit funds), members who want the pot early bid for it: they accept a little less, and the difference is shared with the others. An example published by the Federal Reserve Bank of Philadelphia: ten members pay $100 a month. An early winner who bids $25 takes an $800 pot; a later winner with the same bid gets $950. Early winners are effectively borrowers; late winners are savers who earn a return.

Can a savings circle build credit?

A traditional circle doesn’t show up on your credit report. In the US, non-profit lending circles do: Mission Asset Fund runs zero-interest circles of $300 to $2,400 with 6 to 12 people and reports payments to all three major credit bureaus. MAF reports an average score increase of 168 points for participants; that is the organisation’s own figure.

The risks, and how to limit them

  1. Default: a member stops paying after receiving the pot. Put newcomers and the members the group knows least at the end of the order. Jamaican partner bankers do exactly this, keeping early draws for established members.
  2. The organiser: a badly kept or misused kitty. Write down from the start whether the organiser takes a turn, a fee, or nothing.
  3. Disputes: “I paid!” with no written record. Log every payment where all members can see it.
  4. Hidden charges: in Kenya, 28.9% of group members reported unexpected charges (FinAccess 2024). Any fee belongs in the written rules.
  5. Fake circles: the US Federal Trade Commission warns about “savings clubs” that promise you’ll make more than you put in and depend on recruiting new members (“Blessing Loom”, “Money Board”, “The Circle Game”). A real circle never pays out more than members pay in.

Frequently asked questions

What happens if someone leaves the circle?

It depends on your rules, which is why you write them before starting. A member who hasn’t received the pot yet is often repaid their contributions at the end of the cycle, or replaced by a newcomer who takes their place. A member who has already received it still owes their contributions until the cycle ends.

How do you decide the payout order?

The most common methods are a draw, a group decision based on need (a birth, school fees, rent), seniority in the group, or bidding. Whatever you choose, write the order down and put the least-known members last.

How many members should a circle have?

Usually 6 to 12. Fewer members means a smaller pot and a short cycle; more members means a bigger pot and a long cycle, with more chance of someone dropping out along the way.

How can you spot a fake savings circle?

Be wary of any promise to receive more than you pay in, any requirement to recruit new members to get paid, or an organiser nobody in the group knows. Those are the signs of pyramid schemes dressed up as savings circles.

In short

A rotating savings circle, known by dozens of names worldwide, lets a group finance each other round after round, with no interest. It runs on trust: written rules, a transparent payout order and tracking everyone can see are the best safeguards. First action: write your next circle’s rules on one page before the first payment.
