Le CAC seul, sans contexte, est d\u00e9nu\u00e9 de sens. Le ratio LTV\/CAC est utile, mais facilement manipulable avec des hypoth\u00e8ses de LTV optimistes. Le retour sur investissement du CAC, mesur\u00e9 en mois, est plus difficile \u00e0 falsifier et plus utile pour la planification de la tr\u00e9sorerie. Un retour sur investissement de 12 mois signifie que la croissance est financ\u00e9e par les flux de tr\u00e9sorerie des clients existants\u00a0; un retour sur investissement de 24 mois signifie qu&#039;un financement externe est n\u00e9cessaire pour se d\u00e9velopper.<\/p>\n<h2>Des indicateurs de r\u00e9f\u00e9rence sectoriels qui ont r\u00e9ellement du sens<\/h2>\n<p>Les PME SaaS les plus performantes atteignent un retour sur investissement en moins de 12 mois. Pour les entreprises SaaS de taille moyenne, ce d\u00e9lai se situe entre 12 et 18 mois. Les entreprises SaaS pour grandes entreprises affichent souvent un retour sur investissement de 18 \u00e0 30 mois en raison de cycles de vente longs et de valeurs annuelles moyennes plus \u00e9lev\u00e9es. Les marques e-commerce DTC b\u00e9n\u00e9ficiant d&#039;une forte fid\u00e9lisation visent g\u00e9n\u00e9ralement un retour sur investissement inf\u00e9rieur \u00e0 6 mois apr\u00e8s le premier achat. Si votre entreprise se situe nettement en dehors des performances de son secteur, la strat\u00e9gie \u00e0 adopter d\u00e9pend de l&#039;\u00e9l\u00e9ment d\u00e9faillant.<\/p>\n<h2>Les deux leviers qui font bouger le retour sur investissement du CAC<\/h2>\n<p>Il faut soit r\u00e9duire le co\u00fbt d&#039;acquisition client (CAC), soit augmenter la marge de contribution par client. La r\u00e9duction du CAC passe par l&#039;optimisation du mix marketing, l&#039;am\u00e9lioration du taux de conversion et la r\u00e9duction des d\u00e9penses inutiles. L&#039;augmentation de la marge de contribution s&#039;obtient en relevant les prix, en pratiquant la vente incitative, en am\u00e9liorant la marge brute (par la r\u00e9duction des co\u00fbts ou le positionnement haut de gamme) ou en fid\u00e9lisant la client\u00e8le afin d&#039;accro\u00eetre le revenu par client. La plupart des entreprises performantes am\u00e9liorent leur retour sur investissement en augmentant leurs marges, et non en r\u00e9duisant le CAC\u00a0; en effet, toute r\u00e9duction des d\u00e9penses marketing a g\u00e9n\u00e9ralement un impact n\u00e9gatif sur le chiffre d&#039;affaires.<\/p>\n<h2>Foire aux questions<\/h2>\n<p><strong>Dois-je utiliser un CAC mixte ou payant\u00a0?<\/strong><br \/>Les deux. Le CAC global inclut tous les clients\u00a0; le CAC payant isole les clients des canaux payants. L\u2019analyse des investisseurs se concentre g\u00e9n\u00e9ralement sur le CAC payant, car il repr\u00e9sente le co\u00fbt d\u2019acquisition marginal, et non le co\u00fbt moyen.<\/p>\n<p><strong>Quel est l&#039;impact du taux de d\u00e9sabonnement sur ce chiffre\u00a0?<\/strong><br \/>Cette formule part du principe qu&#039;un client reste au moins jusqu&#039;\u00e0 l&#039;amortissement. Si votre taux de d\u00e9sabonnement mensuel est de 8%, la moiti\u00e9 de vos clients r\u00e9silient leur abonnement avant le 12e mois\u00a0; un amortissement sur 14 mois signifie concr\u00e8tement que de nombreux clients ne r\u00e9silient jamais leur abonnement. Les entreprises ayant un taux de d\u00e9sabonnement \u00e9lev\u00e9 ont besoin d&#039;un amortissement beaucoup plus rapide.<\/p>\n<p><strong>Est-ce important pour les achats ponctuels\u00a0?<\/strong><br \/>De fa\u00e7on moins directe, mais l&#039;indicateur parall\u00e8le est la marge sur co\u00fbts variables par premi\u00e8re commande. Si cette marge ne couvre pas le co\u00fbt d&#039;acquisition client (CAC), vous prenez un risque avec la deuxi\u00e8me commande\u00a0; or, il est crucial d&#039;\u00e9valuer la fiabilit\u00e9 de ce pari.<\/p>\n<div class=\"rt-cta\">\n<h3 style=\"margin:0 0 6px\">Besoin d&#039;aide pour r\u00e9duire le CAC et acc\u00e9l\u00e9rer le retour sur investissement gr\u00e2ce \u00e0 un meilleur mix de canaux ?<\/h3>\n<p style=\"margin:0;opacity:.95\">L&#039;agence Riman con\u00e7oit des programmes de marketing SaaS avec des strat\u00e9gies de croissance ax\u00e9es sur le retour sur investissement.<\/p>\n<p><a href=\"\/fr\/contact\/\">Contactez notre \u00e9quipe SaaS<\/a><\/div>","protected":false},"excerpt":{"rendered":"<p>CAC Payback Period Calculator Calculate how many months it takes for a new customer to pay back their acquisition cost \u2014 the SaaS metric VCs scrutinize, and the metric most marketers ignore.
