Calculate the cost of human BEHAVIOUR in your organisation.

THE MISS THAT NEVER GETS TRACED BACK.

Every sales organisation loses revenue it never attributes to anyone. Not to the market, not to the product — to the way a team is led. The deal that wasn't pushed because the leader ducked the call. The rep who left because the hard conversation came too late. The target quietly accepted instead of negotiated. None of it shows up as a line item, because the cost splits in two: some lands on the top line as revenue you didn't book, the rest on the bottom line as people you had to replace. Each half looks survivable on its own. Together they're a leader-shaped hole in the number — and nobody traces it back.

Gallup attributes roughly 70% of the variance in a team's engagement to one person: its manager. The same research finds the most engaged sales teams outsell the least engaged by around a fifth. A reactive leader — one managing how they're seen rather than saying what needs to be said — sits at the wrong end of that gap. This calculator prices what that's costing, on both ledgers at once.

WHAT IT MEASURES.

The model prices the same pattern in two places. On the top line, it takes the revenue gap between high- and low-engagement sales teams, attributes the share a leader is responsible for, and deliberately halves it — a reactive leader drags a team, but doesn't single-handedly move it from best to worst. On the bottom line, it counts only the rep churn above your normal turnover, plus the quota a ramping replacement can't yet carry. It adds the two against figures you already hold: your target, your headcount, your turnover, what a rep costs. The output isn't a forecast and it isn't a promise. It's revenue currently at risk and recoverable — an order of magnitude, not a decimal place. The realised figure is the one you measure together, afterwards, against your own baseline.

FREQUENTLY ASKED.

WHAT IS A REACTIVE SALES LEADER?

A leader whose default under pressure is self-protection rather than candour — taking over deals instead of coaching, deferring the difficult performance conversation, accepting an unrealistic target rather than negotiating it, smoothing conflict with other functions instead of forcing the issue. The Leadership Circle calls these reactive patterns and places around three in four leaders in one. They rarely look like failure. More often they look like effort — which is exactly why they go uncosted.

HOW CAN ONE LEADER MOVE A NUMBER THIS LARGE?

Because a sales leader doesn't sell — they multiply. Every habit they model, every conversation they avoid, every good rep they lose is amplified across the whole team and repeated every quarter. Gallup attributes about 70% of a team's engagement to its manager, and engagement is what separates the teams that hit from the teams that explain. One leader, scaled across a team, across a year — it's the multiplication most sales organisations never stop to do.

WHERE DO THE FIGURES COME FROM?

The revenue gap draws on Gallup's Q12 meta-analysis, which finds roughly a 20% difference in sales between top- and bottom-quartile engagement teams, alongside its finding that managers account for around 70% of engagement variance. The churn and ramp figures use your own numbers and conservative industry benchmarks. One join is ours: linking a reactive leadership pattern to lower engagement is Single Session's reasoning, not Gallup's — which is why we call this a modelled estimate and keep every assumption visible. We'd rather understate a number than have a CRO wave it away.

IS THE RESULT PRECISE?

No, and it isn't meant to be. It's a credible estimate built on published research and deliberately cautious assumptions. Read it the way you'd read a pipeline coverage ratio — a signal that something needs attention, not a guarantee of the close.

WHAT'S THE DIFFERENCE BETWEEN "AT RISK" AND "GENERATED"?

Everything. Before any work, the number is revenue at risk — what the pattern is plausibly costing you, modelled. We never call it generated, because nothing has been. "Generated" is the word we earn afterwards, when the lift is measured against your baseline. Any tool that promises generated revenue up front is selling you a hope; this one shows you an exposure.

CAN A REACTIVE LEADER ACTUALLY CHANGE?

Yes — but not through another sales-management course. Skills sit on top of the pattern; under pressure the pattern wins. It shifts when the belief driving it is surfaced and resolved, which is the basis of the Single Session approach. Behaviour follows belief. Change the second and the first follows.

HOW IS THIS DIFFERENT FROM MY FORECAST OR CRM?

Your forecast tells you what the number is likely to be. This tells you how much of the gap to target is leadership-shaped — and therefore fixable — rather than down to market or product. One reports the weather; the other points at something you can change.
