What is a merry-go-round? The complete guide to rotating savings circles
How merry-go-rounds, susu, chama and other rotating savings circles work, why they're so popular, the risks to watch for, and how to run one fairly.
A merry-go-round is one of the oldest and simplest ways people save together. A group of friends, colleagues or neighbours agree to pay the same amount on a regular schedule — say GHS 200 every month — and each time, the whole pot goes to one member. The order rotates until everyone has had exactly one turn.
Economists call it a rotating savings and credit association (ROSCA). You probably know it by a local name: susu or nnoboa in Ghana, chama in Kenya, esusu or ajo in Nigeria, tontine in francophone Africa, stokvel in South Africa, committee in parts of South Asia, tanda in Mexico. The mechanics are the same everywhere.
How a merry-go-round works, step by step
- Agree the basics. How much each person pays (the contribution), how often (weekly, fortnightly or monthly) and when the first payout happens.
- Decide the payout order. Who receives the pot in round one, round two and so on. This is the single most important decision — see how to decide the payout order fairly.
- Everyone pays in each round. Contributions go to the person whose turn it is (or to an organiser who passes it on).
- One person takes the pot. With 10 members paying GHS 200, the pot is GHS 2,000.
- Repeat until everyone has had a turn. After 10 rounds the circle is complete. Many groups immediately start another.
A worked example
Ten colleagues each contribute GHS 200 on the last Friday of every month.
| Round | Month | Receives | Pot |
|---|---|---|---|
| 1 | January | Ama | GHS 2,000 |
| 2 | February | Kofi | GHS 2,000 |
| 3 | March | Esi | GHS 2,000 |
| … | … | … | … |
| 10 | October | Yaw | GHS 2,000 |
By October, each person has paid in GHS 2,000 and received GHS 2,000. Nobody gains or loses money — but Ama had GHS 2,000 in January, something she could only have saved alone by October.
Why people love merry-go-rounds
- Early access to a lump sum. Everyone except the last person gets their money sooner than saving alone. For the first person it's effectively an interest-free loan from the group.
- Commitment and discipline. It's much harder to skip a payment your friends are counting on than to skip a transfer to your own savings account.
- No bank, no paperwork, no fees. A shared WhatsApp group and a notebook are enough to start.
- Social glue. Many circles double as a monthly get-together.
The risks — and how good groups manage them
| Risk | What it looks like | How to reduce it |
|---|---|---|
| Default | Someone who has already received the pot stops paying | Put newer or less-known members later in the order; ask for a guarantor; agree penalties in writing |
| Disputes about order | "Why does she always go first?" | Use a transparent random draw and record it — our free planner spins a wheel in front of everyone |
| Lost records | Nobody is sure who paid in March | Keep one shared record everyone can see |
| Organiser misuse | Money is collected but not passed on | Pay the recipient directly by mobile money, or rotate the organiser role |
| Emergencies | A member needs money before their turn | Allow swaps if both members agree, and record them |
Most problems come from unclear rules rather than bad people. Writing down a one-page agreement before the first round prevents almost every argument. We've put together a merry-go-round rules template you can copy.
Merry-go-round vs a savings group
A merry-go-round moves money between members; it doesn't build a shared pot. If your group wants to lend to each other, earn interest, or keep a welfare fund for funerals and hospital bills, you need an accumulating savings group instead. See merry-go-round vs savings group for when to switch.
How to start one this week
- Message 5–15 people you trust and agree the amount and frequency — see weekly, fortnightly or monthly for choosing the schedule.
- Pick a start date that suits when most people get paid.
- Do a fair, recorded draw for the order.
- Share the rules and the payout calendar with everyone.
- Remind people a few days before each payment — these WhatsApp templates help.

Frequently asked questions
Is a merry-go-round the same as a susu or a chama?
They are close cousins. "Merry-go-round" usually means a pure rotating savings circle where the whole pot goes to one member each round. Susu (Ghana) and chama (Kenya) can describe exactly that, but many chamas also save and invest together beyond the rotation.
Does anyone earn interest in a merry-go-round?
Not in a classic merry-go-round. Everyone pays in and takes out exactly the same amount. The benefit is getting a lump sum earlier than you could save it alone, plus the discipline of paying on a schedule.
How many people should be in a merry-go-round?
Most work best with 5 to 20 people who know each other well. Fewer people means a smaller pot; more people means a long wait for those at the end of the order and more chances that someone drops out.
What happens if someone stops paying?
That's the main risk. Agree in advance what happens — for example, the defaulting member forfeits their turn, or a guarantor covers them. Our guide on members who don't pay covers the options.
