Compare opportunities created in the same cohort because open deals and long sales cycles can distort period totals. The rule is Close rate = won opportunities ÷ qualified opportunities. Its input values are Qualified opportunities, Won opportunities, Average won deal value, and the main result is Opportunity close rate. Try changing one number and watch what happens to Opportunity close rate.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Close rate = won opportunities ÷ qualified opportunities, evaluated from Qualified opportunities, Won opportunities, Average won deal value to produce Opportunity close rate. Compare opportunities created in the same cohort because open deals and long sales cycles can distort period totals. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
