Formulas Used
  • Attributed Revenue = Revenue × (Attribution % / 100)
  • Net Revenue = Attributed Revenue × (1 − Tax%/100) × (1 − Refund%/100)
  • ROAS = Net Revenue ÷ Ad Spend
  • ACOS = Ad Spend ÷ Net Revenue
  • CPC = Ad Spend ÷ Clicks, CPM = (Ad Spend ÷ Impressions) × 1000
  • CTR = (Clicks ÷ Impressions) × 100, CVR = (Conversions ÷ Clicks) × 100
  • CPA = Ad Spend ÷ Conversions, AOV = Net Revenue ÷ Conversions
  • Profit = Net Revenue − COGS − Ad Spend − Other Costs
  • Break-even ROAS = 1 ÷ Gross Margin (Gross Margin = (Net Revenue − COGS) ÷ Net Revenue, or an override)

ROAS connects spend to revenue

ROAS is calculated as net revenue divided by ad spend, expressed as a multiplier. In the example table, total spend is 1,200 and revenue is 5,400, producing 4.50x before adjustments. Use the target field to compare performance against your required return and flag underperforming periods.

Net revenue adjustments reduce noise

The calculator lets you attribute only a portion of revenue to paid activity. Set attribution to 80% when analytics shows mixed sources, then remove tax and refunds to align with finance reporting. If tax is 5% and refunds are 2%, a 5,400 gross figure becomes 5,400×0.80×0.95×0.98, tightening ROAS to what you can actually keep. Useful for marketplaces and mixed attribution.

Unit economics reveal break-even points

Profit matters when margins vary. Enter COGS and other costs to estimate contribution profit: net revenue minus COGS, ad spend, and overhead. Using the example inputs with 2% refunds, net revenue is 5,292; with COGS 2,400, spend 1,200, and other 150, profit is 1,542. Break-even ROAS is derived from gross margin, using 1 divided by margin. A 40% margin implies 2.50x break-even; a 25% margin implies 4.00x, changing thresholds.

Traffic metrics explain ROAS movement

ROAS alone can hide funnel issues. Add impressions, clicks, and conversions to get CTR, CPC, CVR, and CPA. With the example totals, CTR is 1,800/65,000=2.77%, CPC is 1,200/1,800=0.67, CVR is 120/1,800=6.67%, and CPA is 10. When ROAS drops, check whether CPC rose, CVR fell, or AOV decreased. The combined view helps isolate auction pressure versus on-site conversion, so fixes target the right stage.

Decision rules for scaling budgets

Use the outputs to set operational guardrails. Scale when ROAS exceeds target and profit margin stays positive. Hold budgets when ROAS is near break-even or CPA creeps upward. Reduce spend when ROAS is below break-even for two reporting windows, then test creative, keywords, and audiences before reinvesting. The efficiency score (0–100) summarizes health; scores above 70 usually indicate stable performance.

FAQs

What does ROAS measure in paid campaigns?

ROAS measures how much revenue you generate for each unit of ad spend. This calculator uses net, adjusted revenue to reduce noise from tax, refunds, and partial attribution.

How is ACOS different from ROAS?

ACOS is the inverse of ROAS: ad spend divided by net revenue. Lower ACOS means higher efficiency, and it is helpful when stakeholders prefer cost percentages instead of multipliers.

Should I enter gross revenue or net revenue?

Enter gross revenue, then use the tax and refund fields to reach a net figure. If your platform already reports net revenue, set tax and refunds to zero to avoid double counting.

How do I choose an attribution rate?

Use your analytics attribution report and pick the paid share of revenue for the same period. If you are unsure, test scenarios like 70%, 85%, and 100% to see sensitivity.

What is break-even ROAS used for?

Break-even ROAS is the minimum return needed to cover product margin before overhead. It comes from 1 divided by gross margin, helping you set bidding and scaling thresholds.

What does the efficiency score mean?

The efficiency score is a simple 0–100 health indicator combining ROAS versus target, CTR, CVR, and profit margin. Treat it as directional, then validate changes with your core KPIs.
