Loan Cost Tips
Frequently Asked Questions
How does reducing balance interest work?
With reducing balance, interest is calculated only on the outstanding loan balance each month. As you repay principal, the balance shrinks and so does the interest portion of each payment. This means you pay less total interest compared to a flat rate method.
How are monthly loan repayments calculated?
Monthly repayments are calculated using the amortisation formula, which spreads the loan into equal monthly instalments. Each payment covers both interest on the outstanding balance and a portion of the principal. Early payments are mostly interest, while later payments are mostly principal.
What is the difference between flat rate and reducing balance?
Flat rate charges interest on the full original loan amount for the entire term, even as you repay. Reducing balance charges interest only on what you still owe. A 20% flat rate loan is much more expensive than a 20% reducing balance loan over the same term - often equivalent to a 35-40% reducing APR.
Why does my microfinance loan cost more than a bank loan at the same rate?
Most Zambian microfinance lenders (Bayport, Izwe, Letshego, and informal kaloba lenders) quote loans as a flat rate per month or per year, while banks quote a reducing-balance APR. A "3% per month flat" microloan is equivalent to roughly 65-70% reducing-balance APR - far higher than the headline number suggests. Always ask the lender which method is being used before signing.
What factors affect total interest paid on a loan?
Three main factors determine total interest: the interest rate, the loan term, and the principal amount. A longer term means more interest even if monthly payments are lower. Making extra payments or choosing a shorter term can save you a significant amount in interest.
How should I compare loan offers from different banks?
Compare the total repayment amount, not just the monthly instalment or headline rate. Check whether the rate is flat or reducing balance, factor in any processing fees or insurance charges, and compare across multiple banks. Use this calculator to see the true cost of each offer side by side.
How is a loan repayment calculated? Show me an example.
Example: K100,000 personal loan at 28% per year (reducing balance) over 24 months. Monthly rate = 28% / 12 = 2.33%. Using the standard amortisation formula, the monthly repayment is approximately K5,489. Total repayment = K131,732, meaning you pay K31,732 in interest over 2 years. The effective annual rate (compounding monthly) works out to 31.89%.
