The True Contribution Margin Formula
What is it?
This is the master formula for your business viability. It combines everything we've discussed into one simple equation to tell you if you are ready to scale.The Formula:
Selling Price
- Landed Cost (Product + Shipping)
- Transaction Fees (e.g., 4%)
- Variable Fees (e.g., Marketplaces)
- CPA (Ad Spend per Sale)
= Contribution Margin ($)
How to Use It for Decisions
- If Positive (+): You are making money on every sale. You can safely spend more on ads to scale up volume.
- If Negative (-): You are losing money on every sale. Stop scaling immediately. Selling more will only bankrupt you faster. You must fix your fundamentals (raise price, lower costs, or improve ads) before spending another dollar.
Pro Tip: Build this formula into a simple spreadsheet. Before you launch any new product, plug in the estimated numbers. If the math doesn't work on the spreadsheet, it won't work in reality.
