Frequently Asked Questions
How do micro loans work in Zambia?
Micro loans are small, short-term loans from informal lenders, savings groups (chilimba), or microfinance institutions. They typically charge a flat interest rate per week or month on the original principal. Common rates range from 10-30% per month.
What is the difference between flat and reducing balance interest?
Flat interest is charged on the full original principal for the entire term, even as you repay. Reducing balance interest only applies to what you still owe. A flat rate of 10% per week costs significantly more than the same rate on a reducing balance.
What is the true annual cost of a micro loan?
A typical informal loan charges around 10% per week flat. Over 4 weeks this can equate to an effective annual rate well above 100% - far higher than the headline rate suggests.
How is total repayment calculated?
Total repayment = Principal + (Principal x flat rate x number of periods). For example, a K 1,000 loan at 10% per week over 4 weeks costs K 400.00 in interest, totalling K 1,400.00.
Are micro loans regulated in Zambia?
Formal microfinance institutions are regulated by the Bank of Zambia under the Banking and Financial Services Act. Many informal lenders operate outside this framework. Always request a written loan agreement and calculate the total repayment before accepting any loan.
