Who This Helps
Growth marketers who wake up to a KPI drop and need the real reason fast. If your CAC just spiked or conversion fell off, this is for you. The Founder Finance Basics Mission Pack gives you the tools to stop guessing and start fixing.
Mini Case
Meet Jenna. She runs growth at a SaaS startup. Last week, her trial-to-paid conversion dropped from 12% to 8%. Revenue looked fine, but cash was flat. She used the CAC Payback Triage mission from the course to check channel-level payback. Turns out, one paid channel had a 7-day payback jump to 45 days. That was the root cause. No more spreadsheets panic.
Do This Now (5 Steps)
- Pull your last 30 days of channel spend and conversions.
- Calculate CAC per channel. Divide total spend by new customers for each.
- Check payback period. Use the formula: CAC divided by monthly gross margin per customer.
- Compare to your target. If payback exceeds 12 months, flag it.
- Decide one action. Pause the worst channel or adjust targeting. You now have a clear next step.
Avoid These Traps
- Don't look at blended metrics. Channel-level data is your friend.
- Don't blame a single campaign without checking payback first.
- Don't forget to account for refunds or churn in your gross margin.
- Don't wait for a full month of data. A 7-day trend can tell you a lot.
- Don't overcomplicate. Three numbers matter: spend, customers, margin.
Your Win by Friday
By Friday, you'll know exactly which channel caused the drop and whether it's a blip or a trend. You'll have a one-page decision card ready for your next team sync. That's the calm founder decision the Founder Finance Basics Mission Pack promises. Plus, you'll look like a hero who fixes things, not just reports them.
