What Is ROI in Paid Advertising?
Have you ever spent money on something and wanted to know if it was worth it? That’s exactly what businesses do when they run ads. They want to know: Did the money we spent bring in more money?
This is where ROI comes in.
ROI stands for Return on Investment. It’s a simple way to check if the money you spent on advertising helped you earn more than you spent. In this article, we’ll walk you through how to measure the ROI of paid advertising—in a way that’s super easy to understand!
Why Is ROI Important?
Imagine you spend $100 on Facebook ads to sell a T-shirt. If you make $300 from those sales, you’ve made a good profit, right? But if you only make $50, then it didn’t work out well.
That’s why measuring ROI is important. It tells you:
- If your ad campaign is working
- If you should keep spending money or stop
- Which ads are performing best
What Is Paid Advertising?
Paid advertising is when a business pays money to show ads on platforms like:
- Google (Search Ads)
- Facebook and Instagram (Social Media Ads)
- YouTube (Video Ads)
- Websites (Banner Ads)
These ads help businesses reach more people and sell more products or services.
The Basic Formula for ROI
Let’s keep it simple. Here’s the most basic formula for ROI:
ROI = (Net Profit / Ad Spend) × 100
Let’s break that down:
- Ad Spend = How much money you spent on the ad
- Net Profit = How much money you made after subtracting your costs
Example:
You spent $200 on Google Ads.
You made $600 from those ads.
Your total cost to make and deliver the product was $300.
So, Net Profit = $600 – $300 = $300
ROI = ($300 / $200) × 100 = 150%
That means for every $1 you spent; you earned $1.50 in profit.
Step-by-Step: How to Measure ROI of Paid Ads
Let’s now go step-by-step so you can measure ROI easily.
Step 1: Set a Clear Goal
Before you run an ad, ask: What do I want to achieve?
Common goals include:
- More sales
- More website visitors
- More sign-ups or leads
- More app installs
Knowing your goal helps you track the right numbers.
Step 2: Track Your Ad Spend
This one is easy. Just keep track of how much you’re spending. Ad platforms like Google and Facebook show you the total amount spent in your dashboard.
Write it down clearly. For example:
- Facebook Ad Spend = $100
- Google Ad Spend = $150
Step 3: Track Conversions
A conversion is when someone does what you wanted them to do—like buy your product, sign up, or download your app.
Use tools like:
- Google Analytics
- Facebook Pixel
- UTM tracking links
These tools show where the user came from and what they did on your site.
Step 4: Calculate Revenue from Ads
Find out how much money you made only from your paid ads.
Let’s say:
- You ran an Instagram ad for your online T-shirt store
- You made 20 sales from that ad
- Each T-shirt sold for $30
So, Revenue = 20 × $30 = $600
Step 5: Subtract Costs
Now, calculate how much it cost to make those sales. Include:
- Cost to produce the item
- Shipping fees
- Payment processing fees
- Any other business expenses
Let’s say:
- Product cost = $12 per shirt
- Shipping = $3 per shirt
- Total cost per sale = $15
So, for 20 sales: 20 × $15 = $300 total cost
Step 6: Use the ROI Formula
Now, plug your numbers into the ROI formula:
ROI = (Net Profit / Ad Spend) × 100
You spent $100 on the ad.
You earned $600 in revenue.
You spent $300 on making and delivering products.
So Net Profit = $600 – $300 = $300
ROI = ($300 / $100) × 100 = 300%
You made 3 times the money you spent!

Your ad should catch attention and look professional.

Common Mistakes to Avoid
Even smart marketers make mistakes. Avoid these:
- Not setting clear goals: If you don’t know what success looks like, how will you measure it?
- Ignoring tracking: Without tracking tools, you won’t know what’s working.
- Only looking at clicks: A lot of clicks doesn’t mean a lot of sales.
- Forgetting about costs: Always subtract your total expenses from revenue to get a true ROI.
