What impacts the car loan comparison rate?
A comparison rate is the 'real' rate of interest when things like extra fees are considered. A big disparity between the interest rate and the comparison rate could mean that the loan comes with large fees which will increaese your repayments.
A comparison rate is good to be aware of but it's not always best to rely on it. That's because a comparison rate is typically based on a specific loan amount and loan term. For a car loan it's based on a loan of $30,000 over a 5 year term. The 'real' rate of interest may be different for you depending on the loan you need.
