Hi Folks

Novice here learning as I go along and would apreciate any help and assistance

I need to show an actual cost versus a budget cost in a 2013 excel spreadsheet as a percentage difference

£12,167 - Actual Cost
£16,000 - Budget Cost

I need to show the difference between the budget cost and theactual cost as a percentage

Would anyone be able to advise me the formula to use in the calculating cell?
