I have a company paid vehicle. I have unlimited usage and my gas is also paid for by the Company. I live in North Carolina and I'm trying to figure out just how much having this perk is worth over a year's time...

That's actually pretty simple.

Determine what you would have to pay in monthly leasing fees for that kind of car. A phone call to a local car dealership can give you that answer.

Then determine your average weekly gas usage, and multiply that by the average cost of gas in your area.

Add about $800 for the annual maintenance costs, and you will have a pretty good estimate of the value of the perk.
