Who This Helps
This is for growth marketers who are tired of pouring budget into channels without knowing if they're actually making money. The Founder Finance Basics Mission Pack gives you the tools to see the real profit picture behind every campaign. You'll move from gut feelings to clear financial facts.
Mini Case
Ben's team was spending $5,000 a month on a social media channel. Revenue from it was up 15%, but his overall cash balance wasn't budging. He ran a quick unit economics snapshot. He found the channel's Customer Acquisition Cost (CAC) was $120, but the average customer was only worth $90 in their first year. Oops. He shifted that budget to a channel with a $75 CAC and a $150 customer value. Cash started growing in 45 days.
Do This Now (5 Steps)
- Grab last month's numbers for your top three spending channels.
- For each channel, calculate total ad spend divided by new customers acquired. That's your channel CAC.
- Find the average first-year revenue from a customer from that channel.
- Subtract the CAC from the average revenue. A positive number is good; a negative number means you're losing money upfront.
- Rank your channels from highest positive number to lowest (or most negative). Your next experiment should focus on improving the winner or fixing the biggest loser. It's like a financial treasure map.
Avoid These Traps
- Don't just look at top-line revenue or lead volume. A channel can look busy but still drain your cash.
- Avoid using blended averages for your whole business. Channel-level math reveals hidden leaks.
- Don't forget to include all costs tied to the channel, like creative or software fees, in your CAC.
- Skipping this check because it feels 'too finance-y' is the fastest way to burn runway on vanity metrics.
- Don't change everything at once. Pick one channel to optimize based on this snapshot.
- Ignoring payback time. A channel with a high CAC can still be great if customers pay you back quickly.
- Getting paralyzed by perfect data. Use your best available numbers and improve the model next month.
- Forgetting to re-run this snapshot quarterly. Channel performance changes.
