ROAS Calculator (2026 benchmarks)
Calculate your ROAS — return on ad spend — and benchmark it against 2026 industry data from 12,000 ad accounts. ROAS varies more by vertical than by ad platform: ecommerce averages 3.0x, SaaS averages 3.5x, finance hits 4.5x. The right benchmark for your business depends on margin and category, not just the number itself.
How ROAS is calculated
ROAS is the simplest acquisition metric in paid media — and the most misused. The number alone tells you nothing without margin context. A 4x ROAS sounds great, but if your gross margin is 25%, your break-even ROAS is 4x — meaning a 4x campaign is exactly breaking even, not making money. Always calculate your break-even ROAS first (1 ÷ gross margin), then judge actual ROAS against that floor. A 3x ROAS in a 70% margin SaaS is wildly profitable; a 3x ROAS in a 20% margin DTC ecom is a slow death.
# ROAS — Return on Ad Spend ROAS = revenue / ad_spend # Example: $25,000 revenue from $5,000 ad spend → 25000 / 5000 = 5.00x (or 500%)
ROAS vs ROI vs MER — which one matters?
ROAS only counts revenue attributed to the ad — typically through tracking pixels and last-click attribution. That misses brand lift, halo effects, and organic conversions influenced by the ad. MER (Marketing Efficiency Ratio) divides ALL revenue by ALL marketing spend, which captures the full picture but loses per-campaign granularity. Use ROAS to optimize individual campaigns. Use MER to set your overall marketing budget. Use ROI when you need to include product cost and decide whether to keep spending at all.
