Search this and one common result is a calculator. Enter the coaching fee, multiply it by a fixed number, and the percentage comes back the same no matter what happened afterward. The industry's own headline figure works the same way: ICF's 2009 Global Coaching Client Study reports a 700% median company return, two sentences after noting that only 9% of respondents supplied enough data to calculate one at all. Neither number asks what else in the business might explain it before the programme gets the credit.
This pack follows the fix instead of the shortcut. The Phillips ROI Methodology that formula descends from sets its own guiding principles. Isolate a programme's real share before crediting it, treat a measure with no data as flat, and exclude an extreme, unsupported claim instead of rounding it down. A per-participant sheet turns each rule into a column: a competing factor named first, then an isolation estimate, then a confidence percentage, multiplied through. It is the same discipline a fractional role's own commitment log applies to calls, turned here on a business result.
At Hollins Systems, a fictional B2B SaaS company, six coached managers were meant to reduce regrettable attrition on their own teams. Crediting every improvement in full, with no exclusions, prices the programme at a 444% return. One manager's 90%-confident estimate gets excluded, because a same-quarter pay correction he never named explains the result at least as well. A sixth manager's team got worse instead, kept in at its full negative value rather than dropped. The adjusted total is $14,700 against a $54,000 cost, a -73% return the naive number never surfaces.
