1. What is the South African Bond Calculator?

The South African Bond Calculator helps homeowners and prospective buyers calculate monthly bond repayments for home loans in South Africa. It uses the standard amortization formula to determine monthly payments, total cost, and interest over the loan term.

2. How Does the Calculator Work?

The calculator uses the bond payment formula:

\[ M = P \times \frac{r \times (1 + r)^n}{(1 + r)^n - 1} \]

Where:

\( M \) — Monthly payment (ZAR)
\( P \) — Principal loan amount (ZAR)
\( r \) — Monthly interest rate (annual rate ÷ 12)
\( n \) — Loan term in months (years × 12)

Explanation: This formula calculates the fixed monthly payment required to fully amortize a loan over its term, accounting for both principal and interest.
