From Revenue Goal to Funnel Math: Working Backwards Like a CMO

Goals fail without math

"Grow revenue 40 percent" is a wish until it becomes a number of customers, which becomes a number of qualified leads, which becomes a number of visitors. The reverse funnel is ten minutes of arithmetic that turns ambition into a work plan.

The calculation

Start at the end and divide upward:

• Customers needed = revenue gap divided by average deal size.
• Qualified opportunities = customers divided by close rate.
• MQLs = opportunities divided by opportunity rate.
• Leads = MQLs divided by qualification rate.
• Visitors = leads divided by conversion rate.

A $100,000 gap with a $5,000 deal size, 25 percent close, 40 percent opportunity rate, 50 percent qualification, and 2 percent visitor conversion needs roughly 20 customers, 80 opportunities, 200 MQLs, 400 leads, and 20,000 visitors. Now marketing has a number.

What the math tells you

Usually one of two things: the visitor target is achievable and the plan is a cadence problem, or the visitor target is absurd and the real work is deal size, close rate, or conversion rate. Both answers are wins; you just saved two quarters of doing the wrong thing.

Make it live, not annual

Wire the funnel to real data and check it monthly. When a stage underperforms the model, that stage is the month's focus. This is exactly the math Marsin builds at onboarding and tracks against your goal.

What if I do not know my rates yet?

Use conservative industry defaults, mark them as assumptions, and replace them with real data within a quarter. A wrong-but-stated assumption beats an unstated one.
