Question 1

How do I calculate my monthly loan or mortgage repayment?

Accepted Answer

Enter your loan amount, deposit, annual interest rate, and loan term in years. The calculator instantly shows your monthly repayment, total interest, and a full year-by-year amortisation schedule.

Question 2

How much of my mortgage repayment goes to interest?

Accepted Answer

In the early years of a loan, the majority of each repayment goes to interest rather than reducing the principal. Use the Principal Capital Paid After field to see the exact split at any point in your loan term.

Question 3

What is an amortisation schedule?

Accepted Answer

An amortisation schedule shows how each monthly payment is split between interest and principal over the full term of a loan. It shows the outstanding balance after each payment until the loan is fully repaid.

Question 4

How much interest can I save by paying more than the minimum repayment?

Accepted Answer

Use the Custom Repayment Amount toggle to enter a higher monthly payment. The calculator will show you the total interest saved, the reduction in loan term, and a side-by-side chart comparing the minimum and custom repayment schedules.

Question 5

How does a lump sum payment affect my loan?

Accepted Answer

Enable the Custom Repayment toggle, then check the Lump Sum Payment option. Enter a once-off amount and the point in your loan term when you'd make it. The calculator will show the revised total interest and loan term — the earlier the lump sum is applied, the greater the saving, since it eliminates interest on that principal for all remaining months.
