ROAS vs ROI: What's the Difference?

In digital marketing, ROAS (Return on Ad Spend) and ROI (Return on Investment) are two key metrics used to measure the effectiveness of your campaigns. Although they may sound similar, they serve different purposes.

✅ What is ROAS (Return on Ad Spend)?

Definition:
ROAS tells you how much revenue you earned for every rupee (or dollar) spent on advertising.

Formula:
ROAS = Revenue from Ads / Cost of Ads

Example:
If you spent ₹10,000 on ads and made ₹50,000 in sales:

• ROAS = 50,000 / 10,000 = 5

• That means you earned ₹5 for every ₹1 spent on ads.

Use Case:

• Best for measuring ad performance.

• Helps optimize campaigns on Google Ads, Facebook Ads, etc.

✅ What is ROI (Return on Investment)?

Definition:
ROI shows how much net profit you made from your overall investment, not just ads.

Formula:
ROI = (Net Profit / Total Investment) × 100

Example:
If you made ₹50,000 in sales, but your total costs (ads, product, staff, shipping) were ₹30,000:

• Net Profit = ₹20,000

• ROI = (20,000 / 30,000) × 100 = 66.7%

Use Case:

• Best for measuring overall profitability.

• Useful for long-term planning and financial decisions.

         🎯 Final Thoughts
