Money bridges: convert coaching into ROI
by Mentor Group

This article explains the practical “money bridges” that convert coaching‑driven behaviour change into financial value your finance team recognises. For the full framework, see our pillar guide: How to measure ROI of executive coaching programmes.
1) Why you need money bridges
Executive coaching reliably improves goal attainment, self‑efficacy and resilience—the mechanisms that drive execution. See meta‑analyses in Frontiers in Psychology (2023) and Theeboom et al. (2013). To evidence ROI, you must link those mechanisms to metrics you already track, then convert changes into pounds using accepted business rules.
2) The four core bridges (with simple formulas)
- A) Win rate → bookings
Behaviour link: better coaching cadence, practice and deal inspection improve conversation quality and qualification, which lifts conversion.
Formula: Incremental bookings ≈ Pipeline × ΔWinRate. Industry round‑ups often report sizeable relative win‑rate lifts when coaching is structured and consistent (directional, context‑specific). For background on coaching effectiveness and commercial links, see Frontiers review (2023).
- B) Forecast error → resource allocation
Behaviour link: cleaner hygiene (next step/date/commitment), healthier stage‑age, and push‑rate control reduce the “mirage pipeline”.
Formula: Hours saved from fewer bad pursuits × Value per hour; plus missed reallocation cost avoided. Forecasting has grown harder for many organisations—see Gartner/HubSpot discussion.
- C) Retention → avoided replacement cost
Behaviour link: higher self‑efficacy and resilience reduce burnout risk; better coaching culture improves manager stickiness.
Formula: Avoided cost = Recruiting fees + Ramp time value + Lost productivity. Case studies that counted retention saw very high ROI, e.g., MetrixGlobal’s Fortune 500 telecom (529%–788%).
- D) Time saved → capacity value
Behaviour link: faster decision cycles and fewer escalations create usable hours.
Formula: (Hours saved per leader × Leaders) × Value per hour.
3) Agree assumptions with Finance (before you start)
- Freeze definitions for metrics and how they’re valued (e.g., which pipeline and period for win‑rate maths).
- Document conservative defaults (e.g., average deal size, value per hour).
- Record any exclusions (e.g., deals with no decision).
4) Worked example (directional)
If a team runs £10m in quarterly pipeline at a £50k average deal size and win rate rises from 24% → 27% (+3 pts), incremental bookings ≈ £300k (0.03 × £10m).
Add hours saved from decision speed (e.g., 2 hours per manager per week × 12 managers × 12 weeks × £70/hour ≈ £20,160) and any avoided backfill cost from improved retention. Keep the arithmetic visible in your dashboard.
5) Tie bridges back to leading indicators
- Win rate bridge → coaching cadence/quality; practice telemetry.
- Forecast bridge → hygiene checks and push‑rate controls.
- Retention bridge → psychological capital (self‑efficacy/resilience).
- Time‑saved bridge → faster decision cycle time.
6) Governance and caveats
- Use conservative valuations; show ranges via sensitivity (±10–20%).
- Avoid double‑counting benefits across bridges.
- Disclose confounders (pricing changes, territory shifts, new product).
- Protect sensitive people data; follow your DPA/ISO processes.

Bottom Line
Q: What are the accepted “money bridges” for coaching ROI?
A: Win rate → bookings; Forecast error → resource allocation; Retention → avoided replacement cost; Time saved → capacity value.
Q: How do we convert win‑rate improvements into bookings?
A: Use Pipeline × ΔWinRate (with agreed period and definitions). Keep the calculation conservative and transparent.
Q: How do forecast‑credibility gains translate to value?
A: Quantify fewer bad pursuits (hours saved × value/hour) and avoided misallocation from pushed deals.
Q: How do we value retention improvements?
A: Sum recruiting fees, ramp time value, and lost productivity avoided for the relevant roles.
Q: How do we turn time saved into capacity value?
A: Multiply hours saved by the number of leaders and an agreed value per hour; avoid double‑counting with other bridges.
