Who This Helps
This is for growth marketers tired of random channel experiments. The Finance Basics for Operators course gives you a one-page operator card to see what's actually moving the needle. You'll stop debating and start fixing.
Mini Case
Viktor saw a 15% increase in sign-ups last week, but his cash balance dropped by $2,000. His profit and cash told different stories because of delayed payments from a big partner. By checking his unit economics, he found his cost per acquisition on the new channel was $45, but the lifetime value of those users was only $38. He was scaling a leaky bucket. Oops.
Do This Now (5 Steps)
- Grab last week's top channel report.
- Isolate the direct cost for that channel (e.g., ad spend, tool fees).
- Pull the revenue directly attributed to it.
- Calculate your simple contribution margin: (Revenue - Direct Cost).
- Rank your channels by this number. The one at the bottom is your next experiment.
Avoid These Traps
- Don't mix overhead costs into your channel math. Keep it clean.
- Avoid vanity metrics like clicks or impressions for this decision.
- Don't assume last month's winner is still winning this week.
- Skipping this check means you might be optimizing a channel that's actually losing money. Not a good look.
Your Win by Friday
By Friday, you'll have identified one specific, weak cost line in your channel mix using a unit economics snapshot. You'll launch a focused test to fix it, moving a real metric without the guesswork. That's a solid week's work.
