This is the valuation-side companion to the operational variance guide. Same discipline — find the gaps that matter — but read through the lens a buyer uses, where some variances are merely operational and others are deal-critical. The choice of which study to measure against is the GPS-vs-BPS comparison.
§ 01 · The severity matrixHow far off, and how urgent.
The profitability study keeps the ±25% significance flag but grades it by magnitude, which sets the response timeline.
| Severity | Variance range | Response |
|---|---|---|
| OK | Within ±25% | Monitor quarterly |
| Moderate | 25–50% | Action plan within 6 months |
| Significant | 50–75% | Immediate attention |
| Critical | >75% | Strategic intervention |
§ 02 · The Rule of 20The one-number screen.
The single most useful variance screen combines the two metrics that drive valuation: organic growth rate plus profit margin. A score of 20 or above marks a strong performer commanding a premium; 15–19 is a solid, market-valued operator; below 15 is discounted territory. The diagnostic value is in the components — if growth is strong but profit is weak, the fix is expense discipline; if profit is strong but growth is weak, the fix is new-business investment; if both lag, the agency needs a comprehensive operational review. It's the fastest read on where an agency sits relative to a buyer's interest.
§ 03 · The critical variancesWhat a buyer prices.
Not all gaps carry equal weight in a transaction. EBITDA and organic growth are tagged critical — EBITDA is the direct valuation multiplier and organic growth selects which multiple applies, so a negative variance on either materially affects price and buyer interest. Retention is read at a tighter ±10% threshold because it compounds and underwrites the earnout. Owner compensation above the peer median is the most common Pro Forma add-back — normalized to a market rate (typically $150K–$250K by tier) and added back to earnings. And productivity (revenue per employee, with tier medians from roughly $145K to $265K in 2024) signals integration risk: low productivity often means post-acquisition staffing change.
An operational benchmark tells you how you run; a profitability benchmark tells you what you're worth. The same variance can be a footnote in a board deck and a headline in a purchase agreement — know which room you're in.
§ 04 · The Pro Forma layerNormalizing before the buyer does.
The discipline that turns variance into value is Pro Forma normalization — recasting the financials the way a buyer will. Cap owner salary at market, strip out non-business perks, add back genuine one-time expenses, and normalize family-member compensation. Done before listing, it raises the EBITDA a multiple applies to and pre-empts the scrutiny a buyer would otherwise apply in diligence. The metric vocabulary behind these terms is the BPS glossary, and the figure all of it feeds is the Book Valuation Engine's deterministic range with named drivers.
