The Profit Waterfall
Every euro that enters your business gets smaller at every step. Here's where it goes, what's healthy, and what to fix first.
1. Revenue Is Not Revenue
Your Shopify dashboard says €100K this month. But that's GMV, not what you actually keep.
After discounts, returns, and taxes, that €100K might be €68K in net revenue. That's the number that counts. Everything else starts from net revenue, not the number your dashboard shows you.
Example: A €100 sale with a 20% discount code and 15% return rate is actually ~€68 net. Start from that number, not the one that feels good.
KLAR tracks 22 KPIs in their full P&L waterfall. We simplify the same logic for decision-making. Same math, fewer spreadsheets.
2. CM1: What Your Product Actually Makes
This is the simplest metric. What's left after you pay for the product itself.
Healthy: 50-70%
Room to grow. Your product makes money.
Red flag: Below 50%
Scaling makes you poorer. Every new sale costs you.
If your COGS is 55%, you're giving away more than half of every sale before anything else happens. No amount of ad optimization fixes that. Fix the product economics first.
3. CM2: What You Have Left to Spend
This is THE metric for media buyers. It defines your budget ceiling. Full stop. If you don't know your CM2, you're guessing how much you can spend on ads.
Healthy: 30-50%
Solid foundation for marketing spend.
Below 30%
Tight margins. Every percentage point of waste hurts.
Components to Audit
Shipping costs
Set your free shipping threshold at 1.4x your AOV. This nudges customers to spend more while covering your costs.
Payment processing
2-4% is standard. Shop around. Negotiate volume discounts. This adds up fast at scale.
Return costs
Assume 50% recovery on returned items. If your return rate is high, this is a massive hidden cost.
Hidden costs
Packaging, pick & pack, 3PL fees. These sneak into your margins and get ignored.
4. CM3: Your Truth
This number tells you if you're building wealth or burning cash. Nothing else matters as much.
Scale Ready
You're profitable. Push harder.
Optimize First
Money on the table. Fix before you scale.
Fix First
Barely surviving. One bad week wipes you out.
Losing Money
Every sale costs you. Stop scaling. Fix the economics.
5. The Four Profit Leaks
If your CM3 is low, one of these four things is the problem. Find it. Fix it. In this order.
Pricing Power
Red flag: Haven't raised prices in 2+ years
"When did you last raise prices? What happened to demand?"
Easiest fix, biggest impact. A 10% price increase goes straight to your bottom line.
Product Costs
Red flag: COGS above 50%
"Can you negotiate better supplier terms? Source differently? Reduce SKU complexity?"
Every percent you save on COGS drops your break-even ROAS and unlocks more ad budget.
Fulfillment
Red flag: Shipping + returns + fees above 15%
"Are you eating shipping costs? What's your return rate? Can you negotiate 3PL rates?"
These costs are invisible on your ad dashboard but they're eating your margin.
Marketing Efficiency
Red flag: Ad cost per order above 25% of AOV
"Are your campaigns structured for profitability or just volume?"
Fix this last. The first three leaks amplify every marketing euro you spend.
Fix leaks in this order: Pricing, COGS, Fulfillment, Marketing.
The first three amplify every marketing euro you spend. Most brands jump straight to marketing optimization. That's backwards.
6. Worked Example: From -3% to 16% CM3
Real scenario. €150K monthly revenue. Platform ROAS at 3.5x. Looked great on the dashboard.
Before: The Dashboard Lie
€150K
Revenue
3.5x
Platform ROAS
-3%
Actual CM3
Losing money on every order. The ad platform showed profits. The bank account showed losses.
What We Changed (8 Weeks)
Raised prices 12%
+7% margin
Demand dropped 3%. Net gain: massive.
Negotiated supplier terms
+4% COGS improvement
Took one call. Should have done it sooner.
Set free shipping at 1.4x AOV
+11% AOV increase
Higher cart value, same shipping cost.
Consolidated campaigns
-18% cost per acquisition
Fewer campaigns, more data per campaign, better bidding.
After: 8 Weeks Later
€145K
Revenue (slightly lower)
3.1x
Platform ROAS
16%
Actual CM3
Revenue dipped 3%. Profit went from negative to €23K/month. The dashboard looked "worse". The bank account looked much better.
The CMO Lens
Most brands look at these numbers once and move on. A fractional CMO builds the waterfall into your weekly rhythm. We check CM2 trends every Monday. When margins shift, we catch it before it compounds. That's the difference between knowing the framework and running it.
