The RAC has what I originally thought was a great online tool for calculating your fuel expenses, it is called the mileage and fuel claim calculator.
You enter in your start pont and destination, then how much per mile you can claim and presto, It calcultes you expenses.
It seem like a great idea until, you think of howw many people would boot up their computer to calculate somthing that is on their milometer anyway.
However on saying this, doing your expenses at the end of the month, for those who do not keep accurate records could be of use.
I also suppose that the relevant head offices who process the claims, could use the tools to check on the accuracy of the expenses claims. MMM

Anyway here is where you can find it rac.co.uk/web/fuelclaim?bannerClick=BB277ID474
