4. Churn rate
A low churn rate indicates happy customers, an effective product, strong marketing, and good retention strategies. Your board will always want to know your churn rate, because it's a huge indicator of how well your product sticks in your market and how likely your company is to have long-term success.
Include user churn and MRR churn in your deck to show your board how customer attrition impacts revenue. You should show both gross MRR churn and net MRR churn—a very low net MRR churn will indicate that you're expanding plans from current customers significantly, which is an excellent growth strategy.
A SaaS company has to meticulously analyze its LTV:CAC ratio because it is the foundation of your unit economics. A high LTV:CAC ratio means that a customer's lifetime value is much greater than your company's costs to acquire them. Customers with high LTC:CAC ratios are very valuable for steady revenue growth over time. The LTV:CAC ratio needs to be over 3:1 in order for the company to be successful in the long-term.
When you present LTV:CAC ratios to your investors, you should break down your customer base into different buyer personas and different acquisition channels. This will show you and your board where your most valuable customers come from and where you need to focus your marketing to spend efficiently.
Measure and communicate these metrics every month to build a rock-solid foundation for your board meetings. Other information, including hiring information, critical discussion topics, a product roadmap, and key wins and challenges, can be presented in additional slides. But these core metrics are the basis for a strong and productive board deck that ensure you get the most out of your meetings.
