Answer
Hence, the proportion of the installment that goes for interest payment is larger at the the begining of the loan period than at the end.
Step-by-step explanation:
At the beginning the loan balance is usually is still large, hence the interest payments would be larger.This is so because the interest payment is calculated by multiplying the interest rate by a big principal balance.
Towards the end of the loan period, when a significant portion of the loan principal balance would have be paid off, the interest payments are usually smaller. This is so because the interest rate is multiplied by a smaller principal balance.
Hence, the proportion of the installment that goes for interest payment is larger at the the begining of the loan period than at the end.
