Section 1 (Breakeven Calculations):    
Mailing Cost /1000
Premium / Incentive cost per order
Gross margin $'s per order
  Marketing ROI (100% equals breakeven) (defaults to 100% - adjust up or down to fit your desired profit % goal.)  
  % of responders that buy (defaults to 100% the maximum - adjust down to meet your goals for this activity.)  
  ROAI Response Rate - Minimum response rate required to achieve desired Marketing ROI (ROAI Response Rate) based on % of responders that actually buy and the specified Marketing ROI %  
  Breakeven Response Rate - Based on Achieving Marketing ROI of 100% at the specified % of responders that buy (best case scenario, 100% of responders buy)
