There is no formula I'm afraid Doc. How could you possibly come up with a standard formula to subtract interest,tax,depreciation and amortisation when every company has totally different debt levels (interest),tax liability (tax-some have tax losses to offset and pay none), and then you have the depreciation etc......which will vary significantly from a company that has very few assets to say someone like UEC for example that has a huge asset base relative to its share price,high capex producing a situation where its operating cashflow and EBITDA are significantly in the black but they are still making a loss overall.
