Loan Repayment Formula
M = P × r(1+r)^n / ((1+r)^n − 1)
- M = Monthly payment
- P = Loan principal
- r = Monthly interest rate (annual rate ÷ 12)
- n = Total number of monthly payments
Total interest = (M × n) − P
Worked Example
Personal loan: R100,000 at 18% per annum over 60 months (5 years).
- Monthly rate: 18% ÷ 12 = 1.5%
- Monthly payment: R100,000 × 0.015 × (1.015)^60 / ((1.015)^60 − 1) ≈ R2,539/month
- Total repayment: R2,539 × 60 = R152,340
- Total interest: R152,340 − R100,000 = R52,340

Frequently Asked Questions
Under the NCA, the maximum rate is repo × 2.2 + 20%. As of early 2026, this is approximately 29.25% per annum.
M = P × r(1+r)^n / ((1+r)^n − 1), where P = principal, r = monthly rate, n = number of payments.
Yes. Under the NCA, early settlement is allowed without penalty. You save all future interest on the remaining balance.
Secured loans use collateral (property, vehicle). Unsecured personal loans carry higher rates due to greater lender risk.
Your credit score, income, existing debt ratio, loan amount and term, whether the loan is secured, and your banking history all affect the rate offered.
