Who This Helps
This is for growth marketers who are tired of throwing budget at channels and hoping something sticks. If you need to move metrics without guesswork, the Founder Finance Basics Mission Pack gives you the tools. It helps you focus effort on the highest-impact move by understanding the real numbers behind your growth.
Mini Case
Ben's revenue was up 15% last quarter, but his cash balance was flat. He was spending on three channels but couldn't see which one was actually profitable. He built a one-page unit economics snapshot. He found that his social ads had a 4-month payback, but his content spend had a 9-month payback. He shifted $5k monthly from content back to social. The result? His cash runway grew by 2 months in just one quarter. That's the power of a simple truth.
Do This Now (5 Steps)
- Grab last month's channel spend and new customer data.
- Calculate your Customer Acquisition Cost (CAC) for each channel. (Total spend / New customers).
- Find the average revenue per customer from those channels.
- Subtract your cost to serve (like platform fees) from that revenue to get gross margin.
- Divide the CAC by the monthly gross margin. That's your payback period in months. The channel with the shortest payback period is your winner. Go fund that one first.
Avoid These Traps
- Don't just look at top-line revenue from a channel. A channel can bring in revenue but still lose you money if the payback is too long.
- Avoid using blended averages. A single 'company average' CAC hides the truth about which specific channels are efficient or dangerous.
- Don't forget to include all costs. If you use a freelancer for a channel, their fee is part of the spend.
- Never prioritize a channel just because it's 'brand new' or 'sexy.' Let the payback period make the boring, smart decision for you.
- Stop changing everything at once. Move budget from your worst-performing channel to your best, then measure for 30 days.
