How the cold call funnel calculator works
An outbound funnel contains several distinct conversion steps. A dial attempt is not a conversation, a booked meeting is not a held meeting, and a held meeting is not a sale. This calculator keeps those denominators separate so a call target can be connected to expected customers and won revenue.
Each rate is conditional on reaching the previous step. If 100 conversations produce 20 meetings, booking rate is 20%, even when the team made 1,000 calls. Mixing a rate measured from all calls with one measured from conversations would count an earlier conversion penalty twice.
Expected customers = calls × conversation rate × booking rate × show rate × win rate (all rates as decimals)
Worked example
Start with the example inputs below. The calculator opens with these values; reset the example at any time to compare your own scenario. Monetary examples use GBP, and all amounts must use the same currency.
| Measure | Value |
|---|---|
| Calls attempted | 1000 |
| Conversation rate (%) | 10 |
| Meeting booking rate (%) | 20 |
| Meeting show rate (%) | 80 |
| Held-meeting win rate (%) | 25 |
| Average won deal value | 5000 |
| Measure | Value |
|---|---|
| Expected conversations | 100 |
| Expected meetings held | 16 |
| Expected customers | 4 |
| Expected won revenue | £20,000.00 |
Each percentage uses the previous step as its denominator. Fractional outputs are expected averages, not guaranteed people or meetings.
How to use the result
Use rates from the same segment and time window, ideally following a completed outreach cohort. Compare an improved conversation rate with an improved show rate to identify where an operational change could matter most. The outputs can help set expectations before scaling a campaign.
Fractional customers and meetings represent statistical averages across repeated campaigns. Keep those fractions while comparing scenarios; rounding every step to whole people would accumulate error. A small campaign may produce very different actual outcomes.
Assumptions and common mistakes
The forecast assumes stable rates and enough time for customers to complete their buying cycle. Increasing calls may reduce targeting quality or exceed available meeting capacity. Revenue is modeled won value, not immediate cash collected, and excludes outreach costs.
