Car loan repayment calculator
Two car loan quotes can look almost identical on the advertised rate and still cost you very differently once fees and commissions are added in.
Our car loan repayment calculator works out your effective rate, the number that actually reflects what the loan will cost, so you can compare quotes properly before you sign anything.
It takes a few minutes and could save you from a loan that looked cheaper than it was.
Why the advertised rate isn't the full story
A car loan’s advertised rate rarely includes everything you’ll actually pay. Establishment fees, ongoing account fees and dealer or broker commissions can all sit outside that headline number.
The effective rate folds all of that in, giving you a single figure that reflects the loan’s true cost. It’s the same principle behind the comparison rate lenders must disclose on home loans, just applied to car finance.
How this calculator helps
- Reveals the real cost behind an attractive headline rate.
- Lets you compare quotes from different lenders and dealers on equal footing.
- Shows how a balloon payment changes your total interest, not just your monthly repayment.
- Gives you a solid number to bring to the negotiating table.
A few things that quietly change the cost
Beyond the headline rate, a handful of details shape what you’ll actually pay over the life of a car loan.
- Balloon or residual payments lower your monthly repayment but leave a lump sum owing at the end, which usually means more interest overall.
- Dealer-arranged finance can bundle in commissions that aren’t obvious from the quote alone.
- Your credit history affects the rate you’re offered just as it does on a home loan.
- A novated lease is a different product again, worth a separate conversation if it’s on the table.
FAQs
What's the difference between the advertised rate and the effective rate?
The advertised rate is the headline interest rate. The effective rate folds in fees and charges, so it’s the more honest number for comparing loans.
Does my credit score affect my car loan rate?
Yes, in much the same way it affects a home loan rate. A stronger credit history generally opens up better offers.
Should I take a balloon payment to lower my repayments?
It can help short-term cash flow, but you’ll usually pay more interest overall and need a plan for the lump sum at the end of the term.
Can I refinance a car loan later?
Often, yes, particularly if your circumstances or the rate environment have changed since you took it out.
Is a novated lease better than a car loan?
It depends on your income, employer arrangement and how you use the vehicle. Worth a proper conversation rather than a rule of thumb.
