To calculate the total amount paid over two years, we first need to determine the annual premium increase percentage. Let's assume the insurer increases the premium by 5% per year to keep up with inflation.
After the first year, the new premium would be:
R450 + (5% of R450) = R472.50 per month
After the second year, the new premium would be:
R472.50 + (5% of R472.50) = R496.13 per month
To calculate the total amount paid over two years, we can use the following formula:
Total amount paid = (monthly premium x 12 months x number of years)
= (R450 x 12 x 2) + (R472.50 x 12 x 1) + (R496.13 x 12 x 1)
= R10,800 + R5,670 + R5,953.56
= R22,423.56
Therefore, you would have paid a total of R22,423.56 over two years.
