• Customers from a funnel par 16 s not tried yet

  worked example

  You have 600 leads. Assume 20% book a meeting and 10% of meetings become customers. How many customers does that funnel give?

  Answer: 12

  1. Each stage uses the stage before it as its base.
  2. 600 × 0.2 = 120 meetings; 120 × 0.1 = 12 customers.

• Overall conversion rate par 13 s not tried yet

  worked example

  Assume 75% of leads book a meeting and one fifth of meetings become customers. What percentage of leads become customers?

  Answer: 15%

  1. Multiply the stage rates: 0.75 × 0.2 = 0.15 = 15%.

• Leads needed for a target par 20 s not tried yet

  worked example

  Assume 25% of leads book a demo and 50% of demos become customers. How many leads do you need for 60 new customers? (Round up to whole leads.)

  Answer: 480

  1. Overall rate = 0.25 × 0.5 = 0.125.
  2. Leads = 60 ÷ 0.125 = 480.

• Stage conversion rate par 10 s not tried yet

  worked example

  270 free trials produced 54 paid customers. What is the trial-to-paid conversion rate, as a percent?

  Answer: 20%

  1. 54 ÷ 270 = 0.2 = 20%.
