Les barrières linguistiques représentent une perte de temps et d’argent.

Elles ralentissent le transfert de connaissances, créent des tensions entre les équipes et augmentent le turnover. Le problème est bien réel, mais il est difficile à prouver sans véritable donnée.

 

Cet outil va vous permettre de calculer le coût lié à l’inaction et d’élaborer un business case à présenter à votre direction. Saisissez les objectifs de votre entreprise, la taille de votre équipe et les coûts actuels pour obtenir une vision claire des coûts engendrés par les barrières linguistiques.

Step 3 · Analysis

Voluntary turnover: let's quantify your retention opportunity

Four short questions to size the opportunity: the metric that matters, where it sits today, where you want it, and what language training can shift.

1

What are we measuring?

Voluntary turnover — the share of people who leave by choice each year, not through redundancy or restructuring.

  • Every voluntary leaver carries a replacement cost: recruitment, onboarding, ramp-up, and lost knowledge.
  • It compounds — the longer language barriers limit engagement and progression, the more embedded it becomes.

2

Where is it today?

Industry average sits around 18%. Retail, frontline, and BPO contexts often run higher.

3

Where does it need to be?

A 5-point improvement is a typical year-one target for a focused learning and development (L&D) programme. LinkedIn's research reports strong learning cultures achieve up to 57% higher retention over time.

4

How much of this is down to language training?

Language is one factor among many. Pick the confidence level that fits — most teams leave this on Balanced.

We apply it as a range and use the midpoint for the headline. A higher band credits more of the gain to language training.

1

What are we measuring?

Language friction — the time your team loses each week to clarifications, rework, slow threads, and meetings that need a translator in the room.

  • McKinsey finds knowledge workers lose about 1.8 hrs a day to information friction; language amplifies that in multilingual teams.
  • It becomes embedded the longer it goes unaddressed.

2

Where is it today?

A rule of thumb: pick ≈0.5 hrs if language friction is occasional, ≈1.5 hrs if it happens most days, 2+ hrs if your team works across languages constantly. Busuu's model assumes 1–2 hrs/week is recoverable per learner once they reach prerequisite proficiency.

3

What's the cost per hour?

We work this out from the average salary you entered (salary × 1.4 for benefits & overhead, over your working weeks at 37.5 hrs). Adjust if you know your real loaded rate.

1

What are we measuring?

Revenue at risk — the annual value of sales that customer-facing staff struggle to close because of language friction.

  • Missed upsells, lost negotiations, and interactions that fall short.
  • The bigger the team and the higher each relationship's value, the larger this gets — and stronger language confidence lifts conversion and CSAT.

What share is language-driven, and what improvement do you expect?

Start at 25% and adjust to your team's language mix and customer base. If language is a key barrier in your sales environment, this may be higher.

What are we measuring?

Production waste — errors, rework, and scrapped output that trace back to communication breakdowns.

  • A clear, real cost operations leaders recognise.
  • Language barriers also carry a safety and compliance dimension — surfaced alongside your results.

Where is it today?

Poor-quality work usually costs from a few percent up to the mid-teens. Default is 7.5% — adjust it to your operation.

How much of this waste is communication-driven?

Set this from what you see on the ground — you know your operation best. Default 35%.

What are we measuring?

Revenue at risk — when customer-facing teams don't share a language with customers, deals slip and customers feel unheard.

  • A daily reality for support, onboarding, and account-management teams working across markets.
  • Shows up as missed renewals, unresolved escalations, and avoidable churn.

Associez la formation linguistique aux indicateurs qui comptent

Les leaders L&D les plus performants ne présentent pas la formation linguistique comme un avantage social. Ils l’associent directement aux indicateurs professionnels tels que la rétention, la productivité, la réduction des risques et le chiffre d’affaires.

Cette approche permet de montrer aux cadres dirigeants qu’une formation linguistique est capable de résoudre de vrais problèmes opérationnels. Lorsque les employés communiquent de façon claire, les projets avancent plus vite, les erreurs diminuent et les meilleurs collaborateurs restent à leur poste.

Il peut s’avérer difficile de prouver le coût de l’inaction à l’aide de données ; tout dépend des objectifs de votre organisation, de la taille de vos équipes actuelles ou à venir ou encore des salaires moyens. C’est pourquoi les business cases les plus solides se concentrent sur les résultats qui intéressent particulièrement votre direction, en utilisant des données qui leur parlent.

Questions fréquentes

Comment mesurer le ROI d’une formation linguistique en entreprise ?

Le ROI dépend de ce qui prime pour votre organisation. Pour certains, il s’agit de la baisse du turnover. Pour d’autres, c’est une intégration plus rapide des employés, une baisse du nombre d’incidents de sécurité ou une plus grande satisfaction des clients. L’essentiel est d’identifier dans un premier temps votre objectif, puis de suivre les indicateurs pour lesquels les compétences linguistiques peuvent faire la différence.

Quels indicateurs sont à prendre en compte dans un business case pour formation linguistique ?

Un business case solide fait le lien entre la formation et les résultats qui intéressent votre direction, avec à l’appui des indicateurs qui lui sont familiers. Parmi les chiffres les plus courants, on peut notamment citer la rétention des employés, les salaires moyens et le coût par utilisateur. Testez notre outil de calcul et découvrez quels indicateurs comptent le plus pour vous et quelle serait la valeur ajoutée d’une formation linguistique.

Comment la formation linguistique peut-elle avoir un impact sur la rétention et la productivité ?

Les employés qui se sentent soutenus sont plus susceptibles de rester à leur poste. En outre, la formation linguistique réduit les tensions quotidiennes, limite les malentendus, accélère la collaboration et facilite le transfert de connaissances. Lorsque les collaborateurs sont en mesure de communiquer plus clairement, leur travail se révèle plus efficace et les liens entre les équipes se resserrent.

Quel est le coût de l’inaction ?

 Le coût de l’inaction, c’est le prix que vous payez quand vous ne réagissez pas aux problèmes de langue. En d’autres termes, c’est le coût généré par des projets plus lents, des erreurs répétées, des clients perdus et un turnover élevé. Cet outil va vous permettre d’évaluer ces frais cachés afin de présenter plus clairement la raison de cet investissement.
