Advertising Return on Investment Parameters

Advertising ROI190.0%Net gain over ad spend
Return on Ad Spend (ROAS)4.50x$4.50 revenue per $1 ad spend
Net Ad Profit$9,500.00After ad spend & COGS

Advertising ROI Formula

Gross Profit = Revenue × Profit Margin %; Net Profit = Gross Profit - Ad Spend; ROI % = (Net Profit / Ad Spend) × 100
  • Gross Revenue: Total sales revenue directly attributed to the advertising campaign.
  • Profit Margin %: Product gross profit margin percentage before ad costs.
  • Advertising ROI %: Net financial percentage return generated purely on advertising capital.

Step-by-Step Worked Example

Scenario: Retailer investing $4,000 in paid ads generating $16,000 revenue at 55% margin

Calculation Steps:

  1. Calculate gross profit: $16,000 × 0.55 = $8,800.00
  2. Calculate net profit after ads: $8,800 - $4,000 = $4,800.00
  3. Calculate Advertising ROI %: ($4,800 / $4,000) × 100 = 120.0%
  4. Calculate ROAS: $16,000 / $4,000 = 4.0x
Result: The campaign produces a 120.0% Advertising ROI and 4.0x ROAS, yielding $4,800.00 net profit after paying all ad costs.

Frequently Asked Questions

How does Advertising ROI differ from ROAS?

ROAS measures top-line revenue per dollar spent (Revenue / Ad Spend), while ROI measures bottom-line net profit after subtracting both product costs and ad expenses.

Can you have a positive ROAS but a negative Advertising ROI?

Yes! If you spend $1,000 to generate $2,000 in revenue (2.0x ROAS), but your product costs $1,500 to manufacture, your net profit is -$500, resulting in a negative -50% ROI.
