Why this piece matters

Plain-English explainers on credit scores, interest, repayment, and how borrowing actually works.

If you have ever applied for a loan, you have seen interest rates quoted in different ways — monthly rates, annual rates, flat rates, reducing balance rates. It can be genuinely confusing, and that confusion often benefits the lender, not you.

Let us break it down clearly.

Flat Rate vs. Reducing Balance

A flat rate charges interest on the original loan amount for the entire duration. A reducing balance rate charges interest only on the outstanding balance, which decreases as you repay.

For example, a ₦100,000 loan at 5% flat rate for 6 months means you pay ₦5,000 in interest every month regardless of how much you have repaid. Total interest: ₦30,000.

The same loan at 5% reducing balance would cost significantly less in total interest because the interest is calculated on a shrinking balance each month.

APR: The True Cost of Borrowing

The Annual Percentage Rate (APR) is the most accurate way to compare loan costs across lenders. It includes not just the interest rate but also any fees, charges, and the compounding effect.

When comparing loan offers, always ask for the APR. A loan with a lower monthly rate but higher fees might actually cost more than one with a slightly higher rate and no fees.

What Affects Your Interest Rate?

Several factors determine the rate a lender offers you:

  • Credit score: Higher scores typically mean lower rates.
  • Loan amount and tenure: Larger loans or longer repayment periods may carry different rates.
  • Lender type: Banks generally offer lower rates than fintechs, but with stricter requirements and slower processing.
  • Collateral: Secured loans (backed by an asset) usually have lower rates than unsecured loans.
