How to Calculate Interest on Monthly Loans

Most people think loan interest is simple — but most loans use monthly payments with compound interest, not simple interest.

  • Most loans use monthly payments — not simple interest.
  • Use this formula: Monthly Payment = P × [r(1 + r)^n] / [(1 + r)^n – 1]
      P = loan amount,
      r = monthly interest rate (annual rate ÷ 12 ÷ 100),
      n = number of months.
  • Example: Borrow ₦100,000 for 12 months at 24% → r = 0.02
  • Monthly Payment ≈ ₦9,392 → Total repayment = ₦112,704 → Interest ≈ ₦12,704
  • Simple interest would say ₦12,000 — but annuity adds more.
  • Most banks use annuity — not flat — even if they don’t say it clearly

👉 Don’t guess your repayment — use the right formula.

Understanding Microloans

Need funding but don’t qualify for a big bank loan? Microloans offer a simple, flexible way to access small amounts of money — especially for business needs.

  • What are microloans? Small loans, usually ₦5,000 to ₦500,000, designed to help individuals start or grow a small business.
  • Why they matter: They’re a great option for people with little or no credit history — especially in informal sectors.
  • Easy to access: Fewer documents, faster approval, and lower barriers than traditional loans.
  • Income boost: A microloan can help you buy tools, stock products, or expand services — all of which can raise your income.
  • Great for first-time borrowers: Repaying on time builds trust and opens doors to bigger loans later.
  • But be careful: Interest rates can be high, and missed payments lead to debt traps. Borrow only what you’re confident you can repay.

Microloans are powerful when used wisely. They’re not free money — they’re a stepping stone to financial growth if managed with care.

Fixed or Variable Interest Rates: Difference

Before taking a loan, it’s crucial to understand how the interest rate works. It can affect how much you pay — and how easy it is to plan your finances.

  • Fixed interest rate: stays the same — your monthly payment never changes.
  • Variable interest rate: can rise or fall — low today, higher tomorrow.
  • Fixed rates = easier to plan your budget.
  • Variable rates = possible savings, but also more risk.
  • Example: fixed rate means paying ₦50,000 every month; variable rate means ₦45,000 one month, ₦60,000 the next.
  • Banks can raise a variable rate — always read the fine print.

If you want stability, go with fixed rates. If you can handle ups and downs, variable might work — but be ready for surprises.
