The price of car convenience

New research reveals the hidden cost of car insurance.

It may be more convenient to avoid paying one big bill, but new research from iSelect has found Australian motorists who choose to pay monthly for car insurance may be spending hundreds more in the long run than those who pay annually.

The car insurance comparison service uncovered Australians could limit their total comprehensive car insurance spend by more than $150 on average in a year by paying annually – based on quotes for three popular models and an example driver profile. On average, the price difference was greater with a higher insurance premium. 11 Source: iSelect quoted comprehensive car insurance policies for three popular new vehicle models on 21 November 2025 with a next-day commencement date. We assumed a driver profile for a 35-year-old male living in Alderley, Brisbane with a 15,000km annual driving distance limit, no claims history, no vehicle modifications, no policy age restriction, and a $900 excess.

The research comes amid record high fuel prices, with paying annually and shopping around for a better car insurance deal being key ways to help cut running costs for motorists.

2025 Tesla Model Y RWD$3,377.65$321.06 ($3,852.74)-$475.10

iSelect comparison expert Sophie Ryan said paying by the month was typically pricier due to added fees from the insurers.

“Not everyone can afford to pay for their car insurance annually, but if you can, it’s worth doing. Otherwise, it could cost drivers more in the long term,” Sophie said.

“Paying by the month means more administrative costs for insurers, which is generally factored into premiums and subsequently passed onto consumers for most policies.

“It may be more convenient and manageable for consumers to pay in smaller amounts, but less so for insurers that need to process up to a dozen payments.

“But not all insurers hike premiums for monthly payments, so it’s worth shopping around if you can’t stump up a large sum annually.

“Ultimately, it depends on your financial situation and whether you’d prefer to tackle bigger costs on a monthly or yearly basis.”
