Marketing ROI Formula

There are two ways to calculate marketing ROI depending on whether you have margin data:

Simple (revenue-based):

ROI = (Revenue − Investment) ÷ Investment × 100

True profitability (with gross margin):

ROI = (Gross Profit − Investment) ÷ Investment × 100

Example: $25,000 revenue × 50% margin = $12,500 gross profit
($12,500 − $5,000) ÷ $5,000 × 100 = 150% ROI

What Is a Good Marketing ROI?

ROI (with margin)	Assessment	Notes
Below 0%	Negative ROI	Marketing costs exceed gross profit generated
0% – 99%	Break Even	Covering costs; not compounding growth yet
100% – 299%	Good	Healthy return; marketing is working
300%+	Excellent	Strong performance; prioritize scaling

Why Revenue-Only ROI Is Misleading

A business with $100K in marketing-driven revenue and $50K in marketing spend has a 100% revenue-based ROI. But if their gross margin is 40%, they only have $40K in gross profit against $50K in spend — meaning they actually lost $10K on that marketing activity. That's why entering your gross margin gives you a much more honest picture of whether your marketing is actually building your business.
