Who This Helps
You're a founder operator who sees a KPI drop and needs to find the root cause fast. This is for anyone in the Finance Basics for Operators course who wants to stop guessing and start acting.
Mini Case
Meet Viktor. He runs a SaaS startup. Last week, his contribution margin dropped from 42% to 30%. He panicked. Instead of digging into every number, he used a simple framework from the Unit Economics Snapshot mission. He found the weak line: a new customer segment had a 60% higher cost to serve. In one hour, he knew the problem and could act.
Do This Now (5 Steps)
- Grab your last 7 days of data. Pull revenue and direct costs for each product or customer group.
- Calculate contribution margin for each line. Use this formula: (Revenue - Variable Costs) / Revenue. Aim for above 40%.
- Compare to last month. If margin dropped more than 10%, flag that line.
- Check for one-time events. Did a big client churn? Did a supplier raise prices by 12%?
- Talk to your team. Ask the person closest to the data: "What changed last week?"
Avoid These Traps
- Don't look at profit first. Profit includes fixed costs and can hide the real issue.
- Don't blame the whole team. Focus on one metric at a time.
- Don't wait for a perfect report. Use what you have now.
- Don't ignore small drops. A 3% dip today can be 15% next month.
- Don't overcomplicate. Three numbers are enough: revenue, variable cost, margin.
- Don't skip the human check. Sometimes the answer is a conversation, not a spreadsheet.
- Don't forget your runway. A margin drop can burn cash faster than you think.
- Don't assume it's a pricing problem. Check costs first.
