ROCI is = (PBIT / CE) *100.
PBIT = Profit Before Interest and Tax
CE = Capital Employed
In theory CE is:
Equity (Eq) + Non-Current Liabilities (NCL).
There is another way to represent CE. If you consider the equation:
NCA + CA = Eq + NCL + CL then
NCA + CA - CL = Eq + NCL
So CE is also Non-Current Assets + Current Assets - Current Liabilities.
ROCE says, in % terms, how profit was generated by each £ 1 of CE.
Hope this can help you.
