Return on capital
Current ratio
EBITDA
Discounted Cash flow

I Was wondering what the forumlaes where for these ratios

I am going to ask for companys accounts for shares i am looking at and work on these ratios etc as i think it will be a good learning curve.

ROC: (Profit/Loss) / (Shareholder Equity + Long Term-Debt)

Current Ratio: (Total Assets) / (Total Liabilities)

EBITDA = Earnings before interest, taxes, depreciation and amortization

You will get it from the financial reports of the companies.

Discounted cash-flow has a more complex formula.

would you divide EBITDA by EV to work out how healthy a company is . Is EBITDA gross profit essentially. and ROC is effectively gross profit / shareholders equity and long term debt.

I would never judge the health of a company based on EBITDA nor would I use fundamental analysis to analyze an equity but that depends on your investment strategy.

No, EBITDA is not gross profit and I gave you the formula to calculate ROC. It's not gross profit divided by shareholder equity and debt but it is profit or loss divided by shareholder equity + debt.
