ROAS (Return on Ad Spend) is a marketing metric that measures the revenue earned for every dollar spent on advertising. It helps e-commerce sellers evaluate the effectiveness of their ad campaigns on platforms like Facebook, Google, Instagram, and TikTok.

A ROAS of 4.0x means you earn $4 for every $1 you spend on ads. Generally, a ROAS above 3.0x is considered good for most e-commerce businesses, though this varies by industry and margins.

To calculate ROAS, divide your total revenue generated from ads by your total ad spend:

• Step 1: Determine your total revenue from the ad campaign
• Step 2: Determine your total ad spend for that campaign
• Step 3: Divide revenue by ad spend

For example, if you spent $500 on Facebook Ads and generated $2,000 in revenue, your ROAS is $2,000 ÷ $500 = 4.0x

Average ROAS varies significantly across e-commerce niches:

• Fashion & Apparel: 3.0x – 5.0x
• Beauty & Cosmetics: 3.5x – 6.0x
• Electronics: 2.5x – 4.0x
• Home & Garden: 3.0x – 5.0x
• Health & Wellness: 4.0x – 8.0x
