ROI vs ROAS Explained

ROI (Return on Investment)

((Revenue - All Costs) / Ad Spend) x 100

Shows your actual profit as a percentage of ad spend. This is the metric that tells you if your business is making money.

  • 100%+ ROI = Doubling your ad investment
  • 50-100% ROI = Solid profitable return
  • 0-50% ROI = Marginal, room to improve
  • Negative ROI = Losing money

ROAS (Return on Ad Spend)

Revenue / Ad Spend

Shows revenue generated per dollar spent on ads. This is what Facebook and Google report, but it ignores all your costs.

Warning: High ROAS does NOT mean profitable

A 3x ROAS with 70% costs = losing money

Frequently Asked Questions

How do I calculate ad spend ROI?

Ad Spend ROI = ((Revenue - All Costs) / Ad Spend) x 100. This gives you the percentage return on your advertising investment. A 100% ROI means you doubled your ad spend as profit.

What is a good ROI on ad spend?

A good ad spend ROI varies by industry. Generally: 100%+ is excellent (doubling your money), 50-100% is good, 0-50% is break-even to marginal, negative ROI means losing money.

What's the difference between ROAS and ROI?

ROAS measures revenue per ad dollar (e.g., 3x = $3 revenue per $1 spent). ROI measures profit as a percentage of investment (e.g., 50% = $0.50 profit per $1 spent). ROI accounts for all costs, ROAS typically doesn't.

Why is my ROAS high but ROI low?

High ROAS with low ROI means your costs are eating into revenue. ROAS ignores COGS, shipping, and fees. If these costs exceed 70% of revenue, even a 3x ROAS results in low or negative ROI.
