Yes. The ability to pay off a home loan early is one of the advantages to having a variable interest rate.
Variable rate home loans generally allow a borrower to make unlimited extra repayments. By paying more than you need to, you could potentially save thousands in interest and shorten the life of your home loan.
Fixed rate home loans, on the other hand, might limit how many extra repayments a person can make and penalise borrowers who surpass such limits.
