Above contribution break-evenAt a 60% gross margin, revenue must be at least 1.67× spend before fixed costs and overhead.

ROAS is revenue ÷ ad spend. Contribution profit applies your gross margin before subtracting ad spend; it is not net profit and excludes salaries, tools, taxes, refunds, attribution gaps and other overhead.

ROAS and profit are not the same metric

Return on ad spend is attributed revenue divided by ad spend. A 3× ROAS means the reporting system attributed three units of revenue for every one unit spent. It does not mean the campaign returned three units of profit.

Contribution profit accounts for the gross margin left after producing or delivering what you sold, then subtracts ad spend. Fixed costs, salaries, software, taxes, refunds and attribution gaps still sit outside this simplified model.

The Meta ads metrics in this calculator

ROAS: attributed revenue ÷ ad spend.
CPA: ad spend ÷ purchases or chosen conversions.
CPC: ad spend ÷ link clicks.
CPM: ad spend ÷ impressions × 1,000.
Click-through rate: link clicks ÷ impressions.
Click-to-purchase rate: purchases ÷ link clicks.
Break-even ROAS: 1 ÷ gross margin rate.

Diagnose the funnel before changing the creative

High CPM can point to a costly audience or weak auction fit. Low click-through can point to the offer or creative. Strong clicks with weak purchases often point to the landing page, qualification, price or follow-up. A blended ROAS number alone cannot tell you where the leak is.

If your ads start conversations on WhatsApp, Instagram or Messenger, response time and handoff quality become part of ad performance. Tenreply keeps those customer conversations and social publishing workflows together so teams can act on the demand campaigns create.
