How do you work out depreciation on a car bought from new?

Hi Frank,

This isn't quite an exact science and you can't really "work it out" but instead you can guess based on evidence from the past. Take a look at what the cars retail for after one year, two years, three years and so on and see what percentage of the car's original value it has retained. There have traditionally been some brands that have kept their value better than others - Ford, Toyota and Volkswagen would be some that spring to mind.
