Paid Ads on Social Media: Costs + ROI Breakdown

Everyone talks about paid ads on social media.

Cheap traffic.
Fast leads.
Easy sales.
Sounds simple.

But the real question is different.

What does it actually cost?
And what return should you expect?

Let’s break it down.

What Paid Ads on Social Media Actually Are

Paid ads on social media are sponsored placements.
Meaning you pay to appear in someone’s feed.

Think about Facebook.
Instagram.
LinkedIn.
TikTok.

You choose the audience.
You set the budget.
The platform delivers the ads.

Simple in theory.
Not always simple in practice.
Because targeting, creative, and landing pages decide the outcome.
Not the button you press.

How Social Media Ad Pricing Works

Most platforms use auction systems.
Advertisers compete for attention.
Higher competition increases costs.

But pricing usually follows two models.
Cost per click.
Or cost per thousand impressions.
CPM.

Here’s a rough guide in Australia.

Facebook and Instagram.
$8 to $18 CPM.

LinkedIn.
$30 to $90 CPM.

TikTok.
$6 to $14 CPM.

These are averages.
Industries change the numbers fast.

For example:
A local café targeting Perth.
Low competition.
Cheap impressions.

A financial services firm targeting executives.
Much higher costs.
Different audience.
Different demand.

The Real Cost of Running Social Ads

Ad spend is only one piece.
Most businesses underestimate the full picture.
Not knowing three costs matter.

Ad budget.

Creative production.

Campaign management.

Example.
A small service business might spend $2,000 per month on ads.
Creative development might cost $500 to $1,500.
Campaign management might sit around $800 to $2,000 monthly.
Total investment.
$3,300 to $5,500.

That’s the real number.
Not just the ad spend.

Why Some Social Ads Work and Others Don’t

Many businesses run ads.
Few run them well.
The difference usually comes down to structure.

Here’s a simple framework.
Offer.
Audience.
Creative.
Landing page.
If one piece breaks, results drop.

Example.
Strong targeting + weak offer = people scroll past.

Strong ad creative + weak landing page = people click, but don’t convert.

You see, the entire path matters.
Not just the ad.

What ROI Should You Expect

Return depends on your industry.
And your average sale value.

Let’s use a simple example.
A physiotherapy clinic runs paid ads on social media.
Ad spend.
$2,000.
Average cost per lead.
$20.
That produces 100 enquiries.
If 25 become patients.
And the average patient value is $350.
Revenue becomes $8,750.
$2,000 ad spend.
$8,750 revenue.

That’s a strong return.

Now compare that to ecommerce.
Margins smaller.
Conversion rates lower.
Different numbers entirely.

Context always matters.

The 3 Metrics That Actually Matter

• Cost per lead.
• Customer acquisition cost.
• Return on ad spend.

Example:
If a lead costs $25.
And it takes four leads to get a client.
Your acquisition cost is $100.
If that client spends $800.
The maths works.
Simple.
Track these numbers early.
Adjust fast.

Common Mistakes Businesses Make

Starting without a clear offer.

This is the biggest mistake.
Ads amplify offers.
They don’t fix them.

Targeting everyone.

Broad audiences waste budget.

Changing campaigns too quickly.

Algorithms need data.
Patience matters.

Sending traffic to the homepage.

That rarely converts well.
Landing pages outperform general websites almost every time.

A Simple Paid Ads Starter Framework

If you’re testing paid ads on social media.
Keep it simple.

Start with one offer.
One audience.
One landing page.

Run a small test.
$30 to $50 per day.

Collect data for two weeks.
Then adjust.
Better headline.
Better targeting.
Better creative.

Small changes compound quickly.

When Paid Social Ads Work Best

Social ads perform best when you have three things.
A clear offer.
A defined audience.
A conversion path.

Service businesses.
Coaches.
Local clinics.
Ecommerce brands.
All can perform well.

But only if the foundation is strong.
Traffic alone doesn’t solve marketing problems.

Paid ads on social media can scale leads fast.
But they are not magic.
They amplify strategy.

Good offers get traction.
Weak offers burn budget.

Focus on structure.
Track the right numbers.
Improve step by step.

That’s how profitable campaigns are built.
