The pipeline gap reveals the real commercial volume you need.
A revenue target is not enough. You need to know how many qualified conversations, held meetings and customers your outbound system must produce every month.

Calculate the pipeline volume you need
Adjust the factors that matter: prospect volume, meeting rate, show rate, customer conversion and monthly prospecting cost.
You need 42 held meetings per month
With your current assumptions, that means roughly 2'451 activated prospects per month.
Meeting gap
37
Missing held meetings per month to reach the target.
Prospect gap
2'151
Additional prospects to activate if rates stay the same.
Simulated monthly revenue
12'240 CHF
Indicative projection based on your conversion rates.
Simulated customers / month
0,6
Potential new customers per month with the current volume.
Cost per held meeting
1'667 CHF
Visible when monthly prospecting cost is provided.
Revenue / cost multiple
1,4x
Reading indicator, not an ROI guarantee.
Prospects x prospect→meeting rate x show rate x meeting→customer rate x customer value. Benchmarks frame assumptions; your real numbers should take priority.
Personalized action plan
37 meetings/month to secure
We turn this result into an action plan: where to win the missing 37 meetings, how many prospects to activate and which rate to fix first. With your current assumptions, the gap represents 2'151 additional prospects per month.

Calculation method
How do you know whether prospecting can pay back?
The calculator does not promise ROI. It makes assumptions visible. If the required prospect volume exceeds your real capacity, the problem is not only sales execution: it touches ICP, buying signals, data, messaging and follow-up capacity.
| Metric | Formula used |
|---|---|
| Booked meetings | contacted prospects x prospect → meeting rate |
| Held meetings | booked meetings x show rate |
| Customers generated | held meetings x meeting → customer rate |
| Simulated revenue | customers generated x average customer value |
Indicative benchmarks
Good rates depend on industry, market and timing.
These ranges frame the discussion. A B2B prospecting campaign should always be judged by segment: target, channel, country, seniority, buying signal and offer quality.
Poorly segmented cold campaigns can stay below 1% prospect → meeting conversion.
Signal-based campaigns with a precise ICP and differentiated messaging can target 2% to 4% or more depending on the market.
Show rate becomes critical when meetings are booked too early, without enough context or without qualification.
Meeting → customer rate mostly depends on offer quality, sales cycle and commercial follow-up after the meeting.

Connect your assumptions to real prospecting cases.
These case studies show why volume alone is not enough: revenue depends on the handoff from targeted prospects to held meetings and signed customers.

FAQ
Frequently asked questions about B2B pipeline calculation
What is a pipeline gap in B2B prospecting?
The pipeline gap is the difference between the number of qualified meetings needed to reach a revenue target and the number of meetings currently generated per month. It turns a commercial target into prospect, meeting and customer volumes.
What prospect-to-meeting rate should we aim for?
The prospect-to-meeting rate depends on market, channel and personalization level. In B2B outbound, a cold campaign can sit below 1%, while a well-targeted signal-based campaign can exceed 2% to 4%. The calculator uses indicative ranges, not guarantees.
Why include show rate?
A booked meeting does not always become a real commercial conversation. Show rate measures the share of meetings that actually happen and prevents overestimating pipeline when no-shows are high or qualification is weak.
Does the calculator replace a sales audit?
No. It gives a quick numerical reading of your assumptions. A GTM audit should also check ICP, available buying signals, data quality, deliverability, messaging, CRM and commercial follow-up capacity.
