How to use the ROI Calculator: 

Step 1: Determine your average client's gross profit margin (GPM) BEFORE filling in the template.  To determine the GPM of your average client, take the annual revenue your average client generates and then multiply it by the number of years a client continues to use your payroll service.  This is usually 7+ years.  You now have the life-time-value (LTV) of a client.  Multiply your average LTV by 60% (the average GPM per payroll client).  If your average client generates more or less money, stays on as a client longer or shorter, adjust accordingly. 

Step 2: Populate the fields with the correct data (do not use dollar signs or commas)
