The sales target is solemnly approved in December. What is almost never approved alongside it is the only question that makes it achievable: how much commercial activity, starting when, is required to produce it? Between the annual target and tomorrow's call is a mathematical chain most companies never calculate — which is why they spend the third quarter putting out pipeline fires.
The math is simple. Let us work through it with a complete example.
The reverse-funnel formula
Start with the target and work up the funnel by dividing by the conversion rate at each stage:
Example: a $600 million new-sales target
- Average deal size: $20 million → you need 30 closes during the year.
- Close rate (proposal→won): 30% → you need 100 proposals presented.
- Meeting→proposal conversion: 50% → you need 200 diagnosis meetings.
- Qualified lead→meeting conversion: 60% → you need 333 qualified leads.
- Qualification rate (raw lead→qualified): 40% → you need about 833 raw leads during the year.
Operational translation: about 70 raw leads per month, 17 diagnosis meetings per month, and eight proposals per month. That is the activity that "buys" the target.
With these numbers, the management conversation changes: if February produced 40 leads instead of 70, the fourth-quarter problem is already visible — and fixable — eight months in advance.
Three refinements that professionalize the calculation
1. Sales-cycle lag
If your average cycle is four months, September leads close in January of the following year. Each quarter's pipeline is built one or two quarters earlier. This explains the classic mistake: cutting prospecting during a good month and paying for the drought two quarters later.
2. Use your own rates, not someone else’s benchmarks
The example rates are illustrative; yours live in your CRM. If you do not have them, use conservative estimates in the first quarter and replace them with real data as soon as it exists. A formula built on invented rates produces decorative targets — disciplined data capture is the prerequisite, as we explain in measuring your funnel's effectiveness.
3. Segment the calculation
Averages hide strategy. A $60 million close with an eight-month cycle and an $8 million close with a six-week cycle do not belong in the same funnel. Calculate by segment or business line, then add them together: you will discover that some segments "buy" the target with half the effort — the foundation of B2B segmentation.
From the math to the weekly plan
The final step is to bring annual activity down to a weekly pace per person. If the team has two executives and needs 17 meetings per month, each must generate and sustain about two new meetings per week — with the upstream prospecting that requires. That weekly number is manageable, auditable, and discussable every Monday; "sell $600 million" is not.
Pipeline coverage is the control indicator: the weighted value of open opportunities should cover three times the following quarter's target. Below that, the warning is generation; consistently above five times, rates are probably inflated or zombie pipeline needs to be cleaned up.
The conversation changes
Once this calculation exists, commercial meetings stop discussing feelings ("the market is slow") and start discussing concrete levers: generate more leads, improve qualification, increase deal size, shorten the cycle. Four levers, each with an owner and a plan. The target stops being a December hope and becomes a governable production system — that is what funnel governance is about.
