I would like to know which common ratios you would defintely recommend in order to make relevant judgements in certain case structures?
For example Proft Margin Ratio (Margin % = (Revenue per unit - costs per unit) / Revenue per unit)) which can then be further analzed in Old Margin vs. New Margin in profitablity cases. Which other ratios / KPIs would you recommend are useful to know for certain case strctures? (e.g. CAGR, ROI, IRR. )
