ROAS vs ROI — what's the difference?
ROAS (Return on Ad Spend)
ROAS = Revenue ÷ Ad Spend. A ROAS of 4x means you earned ₹4 for every ₹1 spent on ads. It measures the gross efficiency of your ad campaign — but does not account for product cost, margins, or overheads.
ROI (Return on Investment)
ROI = (Profit ÷ Ad Spend) × 100. It accounts for what you actually keep after paying for the ad. A positive ROI means you made more than you spent. A 4x ROAS on a 25% margin product could still be a loss.
What ROAS should you target?
Your break-even ROAS = 1 ÷ Gross Margin. If your margin is 40%, you need at least 2.5x ROAS to break even. Aim for 3–5x as a healthy benchmark for most e-commerce and service businesses in India.
ROAS and GST
When calculating ROAS for GST-registered businesses, use revenue excluding GST (your taxable turnover). Ad platform reported conversions include GST in order value — adjust accordingly to get your true ROAS.
