Platform ROAS vs MER: Meta reports ROAS using its own attribution model — it often over-credits sales that would have happened anyway. MER (total revenue ÷ total marketing spend across all channels) is the true measure. Use this calculator for campaign-level decisions; check your MER monthly to make scaling decisions.

Platform ROAS vs MER

Platform ROAS = Revenue attributed by Meta ÷ Meta ad spend  |  MER = Total revenue ÷ Total marketing spend (all channels)

When multiple platforms run simultaneously, each claims credit for the same sales. MER uses total business revenue which cannot be double-counted.

Frequently Asked Questions

The Australian eCommerce average is approximately 2–3x blended ROAS. Strong accounts achieve 4–6x platform ROAS. Calculate break-even ROAS (1 ÷ gross margin) first — for 40% margin, break-even is 2.5x, so targeting 4x or above generates meaningful profit.

MER = total revenue ÷ total marketing spend across all channels. Platform ROAS is over-attributed when multiple channels run simultaneously — each claims the same sales. MER uses total business revenue which cannot be double-counted.

Break-even ROAS = 1 ÷ Gross Margin. Margin 40% → 2.5x. Margin 25% → 4x. Any ROAS below break-even loses money on variable costs.

Australian average Meta CPM ranges from $12–$25, typically $15–$18 for broad targeting. What matters is cost per result, not CPM in isolation.

Facebook feed averages 0.9–1.3% CTR. Instagram feed averages 1.0–1.6%. Above 2% is strong for cold audiences. CTR is primarily driven by creative quality.

Meta's default attribution includes view-through conversions and overlaps with other channels. Calculate MER (total revenue ÷ total marketing spend) for an accurate picture — the gap shows attribution overlap.
