Loan Amortisation Schedule

Total Home Loan Cost

The donut chart provides a summary of your total home loan cost. It visualizes the ratio between the principal (the home loan repayment amount for a given loan) and the total interest paid.

Key Terminology

Amortisation (Amortization)

The process of paying off a home loan over time. The mortgage amortisation calculator schedule shows how each repayment is split between principal and interest.

Principal

The original amount of money borrowed to purchase the property.

Interest

The cost of borrowing money from the lender, expressed as a percentage.

Equity

The portion of your property you own outright. It's the difference between the property's value and your outstanding loan balance.

Loan-to-Value Ratio (LVR)

The ratio of the loan amount to the property's value. For example, borrowing $400,000 for a $500,000 property gives an LVR of 80%.
