Formulas for consulting interviews

Hi all,

I hope you are doing well. Do you have any cheat sheet on the must-known formulas for consulting interviews (maybe in a case book)? 

Here is what I have on mind: payback period, NPV, DCF, Breakeven point, contribution margin, 72 rule, annuity, perpetuity...

Thanks a lot for your help

Best,

Here is a list of the necessary math and formulas:

  • Interest rates calculations
  • Compound margin
  • NPV using the Rule of 72, Perperuity
  • CAGR using the Rule of 72
  • Little's Law
