VICOBA Savings Groups in Tanzania: How They Work

Village community banks, known as VICOBA, are among the most common ways Tanzanians save. A group of people who know and trust each other, usually 15 to 30 members, meets regularly, often weekly, to save and lend. There is no bank building and no outside owner: the group's money belongs to the members, and the profits stay with them. This guide explains how VICOBA savings groups in Tanzania work, why they succeed, the rules that keep them strong, and their limits.

How a VICOBA cycle works

Most groups run in cycles of about a year. At each meeting, members buy shares, typically between one and five at a fixed price, so people with less money can still take part. The money goes into a lockable box with several keyholders, or increasingly into a group bank or mobile money account.

Members can borrow from the pot, usually up to a multiple of the shares they own, and repay with interest over a few months. That interest is the group's profit. Many groups also keep a small social fund, to which everyone contributes a little each meeting, to help members facing a funeral or illness.

At the end of the cycle comes the share-out. Loans are repaid, and the total in the box, savings plus all the interest earned, is divided according to how many shares each member bought. Members often time the share-out for when they need a lump sum, such as school fees in January or the planting season.

A simple example

Imagine a group of 20 members, each buying shares worth TZS 10,000 a week for 50 weeks. Together they save TZS 10,000,000 over the cycle. If the group lends that money to members and earns TZS 1,500,000 in interest, the share-out is TZS 11,500,000. A member who bought the same number of shares as everyone else receives TZS 575,000, against TZS 500,000 saved, a return of 15% for the year. Actual returns depend on how much is lent and how well loans are repaid.

Why VICOBA groups work

VICOBA groups succeed because they combine discipline with trust. Saving at a fixed meeting, in front of others, builds a habit that is hard to keep alone. Loans are available quickly without collateral, because members know each other and the group's pressure encourages repayment. And because the interest stays inside the group, members effectively earn it back.

Rules that keep a savings group strong

The groups that last have clear written rules, known to every member: the share price, the maximum loan, the interest rate, fines for lateness, and what happens if someone cannot repay. They keep records of every transaction, ideally in each member's passbook as well as the group ledger, and they elect officers who change regularly so that no one person controls the money.

Under Tanzania's Microfinance Act, community savings groups fall in the lowest tier of microfinance and are expected to register with their local authority. Registration makes it easier to open a group bank account and to get support or training from local government and development organisations.

Limits to know

A VICOBA's money is only as safe as its members' repayments and its record-keeping. Cash boxes can be stolen, and a few large unpaid loans can wipe out a year's profit. Keeping group funds in a bank or mobile account and limiting loan sizes reduce those risks. Members should also avoid borrowing more than they can repay from their regular income.

Combining VICOBA with other savings

A savings group is excellent for building a habit and getting quick loans, but its money is shared out each year. For savings you will not need for years, combine your group with options such as unit trusts or Treasury bills. Mobile money can also be a safe way to hold small balances; see our guide to saving with mobile money in Tanzania.
