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 see the real profit behind each customer, so you can fund what actually works.
Mini Case
Ben’s revenue was up 15% last quarter, but his cash balance was flat. He was spending $50 per sign-up across three channels. A quick unit economics snapshot showed the truth: Channel A had a $30 Cost of Goods Sold (COGS), making its true cost $80 per customer. Channel B’s COGS was only $10, for a total cost of $60. Channel B was the real profit driver. Ben shifted 70% of his budget there, and net profit grew by 22% in six weeks. The numbers don't lie.
Do This Now (5 Steps)
- Grab last month's data for your top three acquisition channels.
- For each channel, note your total spend and the number of customers it brought in.
- Find the average COGS or service cost for those customers. (If you don't know, use 20% of the sale price as a starter guess).
- Add the COGS to your marketing cost for each customer. This is your true cost per acquired customer.
- Rank your channels from lowest to highest true cost. The channel at the top gets your next experiment budget. It’s like a treasure map for your money.
Avoid These Traps
- Don't optimize for top-line sign-ups alone. A cheap sign-up that costs a fortune to service is a leaky bucket.
- Avoid making decisions based on last quarter's averages. Costs and customer behavior change. Use recent data.
- Don't ignore small channels. A niche channel with fantastic unit economics is often better than a big, expensive one.
- Never assume your pricing covers your costs. Run this check after any price change.
- Stop guessing payback time. If you don't know your true customer cost, you can't calculate it.
- Don't let “growth at all costs” mentality burn your runway. Profitable growth is sustainable growth.
- Avoid analyzing in a vacuum. Share your unit economics snapshot with your finance person. Alignment is magic.
- Never skip this step because it feels “too finance-y.” It’s just arithmetic, and it protects your job and the company's cash.
