Meta Ads ROAS

Meta Ads break-even ROAS calculator guide

Meta Ads ROAS is useful only after you compare it with your product margin. Break-even ROAS shows the minimum ad efficiency needed before scaling spend.

What this means

Meta may report attributed purchase value, but the seller still pays for product cost, shipping, payment fees, discounts, packaging, refunds, and ad spend. A 3x ROAS can be safe for one product and risky for another.

Formula

breakEvenRoas = netRevenue / contributionMargin

Use net revenue after discounts. Then subtract variable costs to find contribution margin. If your Meta Ads ROAS is below break-even, the campaign may lose money before fixed overhead.

Example

If net revenue is $45 and contribution margin before ads is $15, break-even ROAS is 3.00x. A Meta campaign at 2.7x needs review before increasing budget.

Common mistakes

  • Using gross purchase value instead of revenue after discounts.
  • Ignoring CPA when ROAS looks acceptable.
  • Comparing blended ROAS to one product with a different margin.
  • Scaling before checking refund and return impact.
