What is the formula to calculate monthly loan installments and what are the steps involved?

To calculate the monthly installments for a loan, we use the present value annuity formula.

Step 1: Identify the given values.

• Loan amount (Present Value, $PV$) = R 600 000
• Annual interest rate ($r$) = 10% = 0.10
• Loan term ($t$) = 5 years
• Compounding frequency = monthly

Step 2: Calculate the monthly interest rate ($i$) and the total number of payments ($n$).
The annual interest rate is compounded monthly, so we divide it by 12 to get the monthly rate.
