What Is Mortgage Amortisation?
Mortgage amortisation refers to the gradual repayment of a home loan through regular payments over a specified period.
Each mortgage payment typically consists of:
Principal
The portion that reduces the original loan balance.
Interest
The portion paid to the lender as the cost of borrowing money.
At the beginning of the mortgage:
- Most of the payment goes toward interest.
- A smaller amount goes toward principal.
As the loan balance decreases:
- Interest charges decline.
- Principal repayments increase.
Eventually, the mortgage is fully repaid.
