Up to 60 members. This assumes everyone pays the same amount every round and nobody leaves early.

The pot each round
£1,000
You collect number 3 of 10. The circle ends after 10 rounds.
Paid in up to your turn
£300
Still to pay after
£700
Total in and out
£1,000
Up to and including your turn you have paid in £300; the other £700 of your pot is like an interest-free loan you pay back over the later rounds.

How a savings circle works

A savings circle, or rotating savings and credit association (ROSCA), is a group that agrees an amount, how often to pay and the order of turns. Every member pays in each round, and one member takes the whole pot, until everyone has had a turn. They go by local names such as stokvels in South Africa, chamas in Kenya, susus in West Africa and the Caribbean, and tandas in Mexico.

Why the order matters

Every member pays in and receives the same total, so nobody earns or loses money on the sums alone. An early turn works like an interest-free loan paid back over the later rounds, and a late turn works like saving up. The main risk is a member who stops paying after taking the pot early, so clear written rules, trusted members and recorded payments all help.
