Cash or Car Decision Tool
If your employer gives you the choice of a company car or a monthly cash allowance, this tool will help you to see which suits you best. Where tax rates for future years have not been announced, the latest current rates have been used, rather than estimates of future increases.
There may not be a clear cut answer because running your own car requires more of your time and effort. Getting a PCP quote makes the comparison easier because finance, the risk of depreciation and some administration costs are contained within a single monthly figure.
