Frequently asked
How do I calculate marketing ROI and break-even ROAS?
ROI = (Revenue - Ad Spend) / Ad Spend × 100. Break-even ROAS = 1 / Profit Margin. If your margin is 40%, you need a 2.5x ROAS to break even. Enter your spend, revenue, and margin to see whether your campaigns are profitable or merely generating revenue at a loss.
What is a good ROAS benchmark by industry?
Average ROAS varies: e-commerce targets 3-4x, B2B lead generation 2-3x, and brand awareness campaigns may accept 1.5x. A 4x ROAS on a 25% margin product yields 100% ROI ($1 spent returns $2 profit). This tool benchmarks your numbers against these standards automatically.
