Prioritize Your Next Growth Experiment with a Unit Economics Snapshot

Who This Helps

This is for team leads who feel stuck choosing between good ideas. The Founder Finance Basics Mission Pack gives you a clear framework to stop debating and start testing what truly moves the needle.

Mini Case

Ben's team had three solid ideas: improve onboarding (could boost retention by 15%), launch a referral program (might cut CAC by $20), and add a new feature (projected to increase average revenue per user by 10%). Instead of arguing, he ran a quick unit economics snapshot. The numbers showed the referral program would improve payback time from 8 to 5 months—the biggest immediate impact on cash. That became the next priority.

Do This Now (5 Steps)

1. Grab your last month's key numbers: new customers, total revenue, and marketing spend.
2. Calculate your basic Customer Acquisition Cost (CAC). Total spend divided by new customers.
3. Find your average revenue per user (ARPU). Total revenue divided by total active customers.
4. Note your gross margin percentage. (Revenue minus cost of goods sold, divided by revenue).
5. Compare your CAC to your customer lifetime value (LTV). A quick proxy is (ARPU Gross Margin) / Churn Rate. If you don't have churn, use (ARPU Gross Margin) * 12 for a rough annual view.

Avoid These Traps

• Don't prioritize based on what's easiest to build. Impact beats speed.
• Avoid analysis paralysis. Use last month's real data, not perfect projections.
• Don't ignore cash flow. A experiment that improves payback time is often better than one that only boosts top-line revenue.
• Stop switching priorities weekly. Pick one experiment based on this snapshot and let it run.
• Don't work in a silo. Share this snapshot with your team so everyone sees the 'why'.
• Avoid vanity metrics. Focus on changes to CAC, LTV, or payback period.
• Don't forget the mission. Remember Ben's problem: 'Revenue is up but cash is flat.' Your snapshot should explain that truth.
• Stop guessing. Let this five-step check be your tie-breaker for every debate.

Your Win by Friday

By Friday, you'll have a one-page unit economics truth—just like the mission outcome. You'll know which of your team's ideas actually improves your business model, and you can confidently greenlight that experiment. No more team meetings spent circling the same arguments. Time to build!
