How to use this calculator

  • Enter the campaign or channel metrics requested in the calculator.

What the result means

The result shows whether ad spend is profitable after margin, not only whether it generates revenue. Strong ROAS with weak margin can still produce poor profit.

ROAS = Revenue ÷ Ad Spend; Ad Profit = Revenue × Gross Margin − Ad Spend

Use contribution margin when possible so the result reflects real profitability after product or service delivery costs.

Example calculation

If ad spend is $5,000, revenue is $25,000, and margin is 60%, ROAS is 5.0x and ad profit is $10,000.

Tips for better results

  • Judge campaigns by profit, not only revenue.
  • Scale gradually when ROAS is strong.
  • Watch marginal CPA as spend increases.

FAQ

How much should I spend on ads to make $100,000 in revenue?

Divide the revenue goal by expected ROAS, then check whether gross margin leaves profit after ad spend.

What is a good ROAS for Facebook ads?

Many campaigns target at least 2.5x to 4x ROAS, but the correct target depends on margin and repeat purchases.

How do I calculate advertising profitability?

Multiply ad revenue by gross margin, then subtract ad spend to estimate ad profit.

How much ad spend is too much?

Ad spend is too high when ROAS, CPA, or profit per conversion falls below your break-even threshold.

When should I increase my ad budget?

Increase budget when ROAS is profitable, conversion quality is stable, and marginal CPA does not rise too quickly.
