Andrew borrowed $20 000 to be repaid in equal monthly repayments of $243 over 10 years. Having made this monthly repayment for 4 years, he increased his monthly repayment to $281. As a result, Andrew paid off the loan one year earlier. How much less did he repay altogether by making this change?
Based on the original repayments, Andrew has to pay 243 × 6 × 12 = $17 496 after the end of year 4.
Based on the increased repayment, Andrew has to pay 281 × 5 × 12 = $16 860 after the end of year 4.
He pays 17 496 – 16 860 = $636 less.
