How to Track Profit Margins Like a Pro (Free Google Sheets Template)
The #1 Mistake Small Business Owners Make
Most entrepreneurs track revenue growth but ignore margin erosion. I've seen SaaS companies with 80% gross margins turn into 40% net margins because they didn't track operating expenses against product lines.
The fix? A simple Profit Margin Tracker that connects your revenue, COGS, and expenses into one dashboard.
What You Need to Track
1. Gross Margin By Product
Formula: (Revenue - COGS) / Revenue
Track this monthly. If a product's gross margin drops below 50%, investigate pricing or supplier costs.
2. Operating Margin
Formula: Operating Profit / Revenue
This tells you if your business model works. Under 15%? You're burning cash.
3. Net Margin
Formula: Net Profit / Revenue
The real bottom line. Public companies aim for 10-20%. As a small business, target 15%+.
The Template
I built a Profit Margin Tracker in Google Sheets that automates all three calculations across 50+ products. It includes:
- Pre-built dashboard with live KPIs
- 8 sample products with realistic data
- 6 expense categories pre-filled
- 3 charts (margin by product, trend line, revenue vs COGS)
- Conditional formatting (green/yellow/red alerts)
