A practical framework for proving the value of the IC function with your own numbers
Key takeaways
- IC ROI is the combination of engagement (did people consume and act on the content) and business outcome (productivity, retention, alignment). You need both halves.
- Published research gives you defensible benchmarks: disengaged employees cost roughly 34% of salary in lost productivity (Gallup), and communication failures account for 42% of turnover intent (SHRM).
- The strongest ROI argument pairs your own communication-engagement data with your existing employee-satisfaction surveys, so you prove the link with your numbers, not just industry benchmarks.

Introduction
Most IC functions are measured by activity (how much they publish) rather than impact (what it changes). Yet the impact is quantifiable. Gallup's research and SHRM's State of the Workplace both put hard numbers on what poor communication costs. This article turns those into a framework you can apply to your own organisation.
Why IC ROI is hard, and why that is fixable
IC ROI is hard for two reasons: communication contributes to many outcomes without a single clean causal line, and most teams measure reach without measuring downstream action. Both are fixable. You do not need a perfect causal model; you need a defensible link between communication engagement and outcomes leadership already tracks, expressed in numbers they already trust. The trick is to measure action, not just views, and to pair your engagement data with existing HR metrics.
It helps to separate two ideas that often get conflated: attribution and contribution. Attribution tries to assign a single outcome to a single cause, which communication rarely allows, because a retained employee was influenced by pay, manager, role, and a dozen other factors as well as by being well informed. Contribution is the achievable claim: communication measurably moved a leading indicator that is itself linked to the outcome leadership cares about. Stop chasing a clean attribution number that does not exist and build a contribution story that does, and the ROI conversation becomes both honest and persuasive.
Practical step: Stop reporting IC in views and posts. Start reporting in reach by audience, action taken, and the correlation with engagement or retention metrics your HR team already collects.
The cost of poor internal communication
The numbers below are published research, not estimates, and they apply to any large organisation:
• Actively disengaged employees cost organisations approximately 34% of their annual salary in lost productivity (Gallup, State of the Global Workplace).
• Highly engaged business units experience 21 to 51% lower employee turnover (Gallup, How to Improve Employee Engagement).
• Employee experience and communication failures account for 42% of turnover intent (SHRM, State of the Workplace).
• Employees who feel informed are 3.5 times more satisfied with their workplace (Quantum Workplace).
For a 5,000-employee organisation, these translate into millions per year in productivity and replacement costs. That is the size of the prize internal communication contributes to.
Practical step: Apply these percentages to your own headcount and average salary to get a defensible cost-of-inaction figure. It is the anchor for your ROI conversation.
The two halves of IC ROI
IC ROI has two halves. The first is the engagement half: did the right audience consume the content, and did they take the intended action? This is the action-to-readership ratio (concrete actions divided by unique readers). The second is the outcome half: does higher communication engagement correlate with higher retention, productivity, or satisfaction? You measure the first directly and establish the second by correlation with existing HR data.
The two halves answer different audiences. The engagement half (reach, and the action-to-readership ratio) is what the IC team controls and reports monthly; it proves the work is landing. The outcome half (the correlation with retention, productivity, or satisfaction) is what leadership funds; it proves the work matters. A common failure is reporting only the first half, which keeps IC in the language of activity, or reaching only for the second, which overclaims a causal link the data cannot support. Carry both, clearly labelled, and the story holds up under finance scrutiny.
Practical step: Define one concrete downstream action for each major campaign (enrolment, completion, declaration). Track the action ratio. That is the measurable, attributable half of your ROI.
A worked example
A strategic campaign mobilises 12 person-days of IC team time at a fully-loaded rate of EUR 600 per day, plus EUR 8,000 of external production: total cost EUR 15,200. It reaches 4,500 unique employees on the target segment and generates 350 concrete actions (programme registrations). Cost per employee reached: EUR 3.38. Cost per action: EUR 43. Compared with the cost of the disengagement those 4,500 employees would otherwise represent, the campaign pays for itself many times over. The numbers make the IC function legible to a finance audience.
Now invert the same example to show the cost of doing nothing. If those 4,500 employees sit in a population where disengagement runs at the levels Gallup documents, the lost-productivity cost attached to that group dwarfs the EUR 15,200 the campaign cost, often by an order of magnitude. You are not claiming the campaign eliminated that cost; you are showing that even a small improvement in engagement across a population of this size pays for the entire programme many times over. Framing the spend against the cost of inaction is usually more persuasive than the cost-per-action figure on its own, because it speaks in the language of risk that finance already uses.
Practical step: Calculate cost per employee reached and cost per action for your last three campaigns. Show the trend. Even rough numbers beat no numbers in a leadership conversation.
Pairing engagement with your survey data
The strongest ROI argument uses your own data, not just industry benchmarks. If your organisation already runs employee-satisfaction surveys, pair that data with communication-engagement data: group employees by region, role, or team; track their engagement with internal content; cross-reference against satisfaction scores. The correlation (employees who are informed and engaged stay longer and score higher) becomes a retention story you can prove with your own numbers. This requires audience segmentation, which native analytics cannot produce, and a platform that can group employees via HR file import without a clean Active Directory.
The mechanics matter here, because the credibility of the claim rests on doing the join properly. You group employees by a stable attribute (region, business unit, role) using Active Directory or an HR file import, measure each group's communication engagement over the same window as the survey, and then plot engagement against the satisfaction or retention score for those same groups. When the better-informed groups also score higher, you have a correlation observed in your own organisation, on your own people, which is far harder for a sceptic to dismiss than a borrowed industry statistic. The one prerequisite is segmentation, which native analytics cannot provide.
Practical step: Ask your HR team for satisfaction scores by team or region. Overlay communication engagement for the same groups. The correlation is your ROI proof.
What not to claim
An ROI story loses more credibility from one overclaim than it gains from three good numbers, so be deliberate about the lines you will not cross. Do not assert that communication alone caused a retention improvement; say it contributed alongside other factors. Do not annualise a single campaign's result into a company-wide figure without saying you have done so. Do not present cost-per-action as if it were profit. Finance audiences are trained to find the weak claim in a deck, and a single inflated number invites them to discount everything around it, including the figures that were sound.
The counter-intuitive result is that the more conservative version of the story is the more persuasive one. 'Communication engagement rose in these regions, retention in the same regions is higher, and here is the published research that links the two' is a claim a CFO can repeat without risk. That repeatability, the willingness of a sceptical executive to carry your number into the next meeting, is the real test of an ROI argument, and it is won by restraint, not by the biggest number you can defend.
Practical step: Before you present, mark the single strongest claim in your deck and ask whether a hostile CFO could break it. If yes, soften it. A claim that survives challenge is worth more than one that impresses until questioned.
How to present it to leadership
One slide. The cost of inaction (applied to your headcount), your action ratios trending up, and the correlation between engagement and retention or satisfaction. Do not over-claim a single causal number; present a defensible story backed by your data plus published benchmarks. That is what moves a leadership conversation from 'IC is a cost' to 'IC is a measurable contributor'.
Practical step: Build a single ROI slide combining one cost-of-inaction figure, one action-ratio trend, and one engagement-retention correlation. Bring it to your next leadership review.

FAQ
Can you really calculate the ROI of internal communications?
Yes, with the right framing. Strict single-cause ROI is rarely computable because communication contributes to many outcomes. But a defensible ROI story is very achievable: measure action taken (not just views), apply published cost-of-disengagement benchmarks to your headcount, and correlate communication engagement with your existing HR metrics. That combination is credible to a finance audience.
What benchmarks can I use?
Gallup: disengaged employees cost roughly 34% of salary in lost productivity, and highly engaged units see 21 to 51% lower turnover. SHRM: communication failures account for 42% of turnover intent. Quantum Workplace: informed employees are 3.5 times more satisfied. Apply these to your own headcount for a defensible figure.
Do I need a special tool to measure IC ROI?
You need audience segmentation and the ability to measure action across channels, which native Microsoft analytics does not provide. A dedicated platform that segments by team or region (via Active Directory or HR file import) and measures engagement cross-channel makes the ROI calculation practical. Tryane is built for this.
How do I link communication to retention?
Group employees by region, role, or team; track their engagement with internal content; cross-reference against your existing employee-satisfaction survey scores. Employees who are informed and engaged stay longer, and with segmented data you can demonstrate the correlation in your own organisation rather than relying on industry averages.
How often should I report internal communications ROI?
Report the engagement half monthly, because it steers the work, and the outcome half quarterly, alongside the leadership review, because correlations with retention or satisfaction only become meaningful over a longer window. Build the ROI view once as a reusable template so each quarter is a refresh rather than a rebuild, which is what keeps the practice alive past the first enthusiastic presentation.
Is Tryane SOC 2 certified and EU-hosted?
Yes, SOC 2 Type 2 certified, GDPR / RGPD compliant by design, EU-hosted by default, with data residency in other countries (notably the US) available on demand. Access is via Azure AD or Entra ID SSO.
