What is a Loan Repayment Calculator?
A loan repayment calculator works out your monthly repayment for a car loan or personal loan from the amount borrowed, interest rate and loan term. It also shows the total interest and total cost of the loan, plus a payment schedule showing how much of each payment goes to interest versus principal.
How Car Loan and Personal Loan Repayments Work
Australian car loans and personal loans are repaid monthly. Each repayment covers the interest on the remaining balance plus a portion of the principal. Most personal loans use a fixed rate, so the monthly repayment stays the same for the whole term — unlike a variable mortgage.
Car Loan vs Personal Loan
A secured car loan uses the car as security and usually has a lower rate. A personal loan can be secured or unsecured — unsecured loans have higher rates because there is no asset backing. Compare both by entering your amount and term in the calculator.
Frequently Asked Questions
How is a loan repayment calculated?
Monthly repayment = P × r × (1+r)^n ÷ ((1+r)^n − 1), where P is the loan amount, r the monthly rate and n the number of months. Each payment covers interest plus principal.
How much is a $30,000 car loan per month?
At 8.5% over 5 years, a $30,000 car loan is about $615 per month. The calculator gives the exact figure including total interest.
What affects total interest on a personal loan?
The interest rate, the term and any upfront fees. Longer terms mean lower monthly payments but much more total interest.
Can I pay off a personal loan early?
Yes. Many lenders allow early repayment, which saves interest. Check whether your loan charges an early repayment fee.
What is the average personal loan rate in Australia?
Personal loan rates vary widely, roughly 7–16% p.a. depending on the lender, loan size and whether it is secured. Compare rates before applying.
Are upfront fees included in the loan?
Some lenders charge application or establishment fees. The calculator lets you add upfront fees so the total cost reflects the real figure.
