Bowjob.
There are way too many variables. Do you drive to work, take public transit? Or a combination? Have a son or two in hockey and put thousands of km on every winter when fuel efficiency drops? Substantially.
One truck and one Prius in the driveway? Or two SUVs?
Foe the purpose of insurance, underwriters say the average driver does 20,000-25,000 km/year.
If we keep it simple and pump prices are $1.00/litre. And every vehicle gets 100 km/10 litre.
Roughly $2,500 in gas. So roughly 1,250 in tax.
When I would talk to people about budgeting. Just for a ball park idea, an annual gas budget of $5,000 per year for a family is not unreasonable. Likely conservative.
