It is the first question almost every business asks us about Facebook and Instagram advertising, and it is the one question that does not have a clean answer. Anyone who gives you a single number without asking what you sell, who you sell it to and what you want them to do is guessing.
That is not a dodge. It is worth understanding why the number moves, because once you understand what drives it, you can tell the difference between an account that is expensive because the market is competitive and an account that is expensive because it is being run badly.
Why published benchmarks disagree with each other
Search for Australian Meta ads benchmarks and you will find confident numbers. The problem is that they do not agree. One widely cited 2026 dataset puts the average Australian CPM at under ten dollars. Another, drawing on billions in ad spend over the same period, reports a median closer to fourteen and a range running from under ten to over twenty-one depending on the month.
Both cannot be right, and it does not matter much which is closer, because neither describes your account. They are averages across thousands of advertisers selling completely different things to completely different people. A furniture retailer in November and a plumber in February are in the same dataset and almost nothing else in common.
What the disagreement does tell you is useful though. Meta advertising costs swing a long way, seasonally and by industry, and a quote built on a benchmark is a quote built on sand.
What you are actually paying for
Meta does not sell you clicks. It runs an auction for attention, thousands of times a second, and you are bidding against every other advertiser who wants to reach the same person at the same moment.
You are not only bidding against your competitors either. You are bidding against anyone who wants that person’s attention. A Melbourne cafe advertising to thirty-five year old women in Brunswick is competing with fashion brands, gyms, insurers and a national retailer running a sale, all of whom want the same slot in the same feed.
That is why cost has less to do with your industry than people expect, and much more to do with who you are trying to reach.
The five things that decide what you pay
1. How narrow your audience is
The tighter you target, the fewer people you can reach, and the more you pay for each one. Advertisers often assume narrow targeting saves money because it cuts waste. In practice it usually does the opposite: you are competing for a smaller pool, so the auction price climbs.
A campaign aimed at business owners in three specific postcodes will cost noticeably more per thousand impressions than one aimed at adults across Melbourne. Whether that is worth it depends entirely on what a customer is worth to you.
2. What you are asking people to do
The further down the funnel your objective sits, the more you pay. Asking someone to watch a video costs less than asking them to click. Asking them to click costs less than asking them to fill in a form. Asking them to buy costs the most.
That is not Meta charging a premium for conversions. It is that fewer people will do the harder thing, so the cost of getting one of them to do it is higher.
3. Whether your creative earns attention
This is the biggest lever and the one most businesses ignore. Meta rewards ads that people engage with by charging less to show them. An ad people scroll past gets throttled and gets expensive.
Two businesses in the same industry, targeting the same audience, with the same budget, can pay very different amounts purely because one made something worth stopping for. When we take over an underperforming account, creative is almost always where the cost is hiding. It is the first thing we look at when taking on Meta ads management for a new client.
4. When you are advertising
Costs rise sharply in the run up to Christmas, and again around the major retail sale periods, because every retailer in the country is bidding at once. A service business advertising in November is paying a premium created almost entirely by other people’s Black Friday campaigns.
If your offer is not seasonal, this is worth planning around. The same budget buys meaningfully more reach in February than it does in late November.
5. How much data the account has
Meta’s targeting improves as it learns which people respond to you. A brand new account with no conversion history is guessing, and you pay for that guessing while it works out who your customers are.
This is why the first few weeks of a campaign usually look worse than the numbers you were shown, and why judging performance after ten days is judging the learning phase rather than the campaign.
What a sensible starting budget looks like
The honest framing is not what Meta ads cost, it is what a customer is worth to you and how many you need.
Work backwards. If a new client is worth two thousand dollars over the time they stay with you, and one in five enquiries becomes a client, then an enquiry is worth four hundred dollars to you. That number, not a benchmark CPM, tells you what you can afford to pay for a lead and therefore what your budget needs to be.
Then set a budget large enough to produce enough conversions for Meta to learn from. A campaign that generates two conversions a week never leaves the learning phase and will look expensive forever. It is usually better to run one properly funded campaign than three underfunded ones.
- Know what a customer is worth before you set a budget, not after
- Fund one campaign properly rather than splitting across several
- Give it long enough to exit the learning phase before judging it
- Expect the first fortnight to look worse than the steady state
The cost that does not appear in Ads Manager
Ads Manager shows you what you paid Meta. It does not show you what the campaign cost your business.
The landing page matters as much as the ad. Sending paid traffic to a slow page, or to a home page rather than a page about the thing you advertised, means paying full price for the click and then losing the person. We have seen accounts where the ads were fine and the entire problem was that the page took six seconds to load on a phone.
Enquiry handling matters too. Paid leads go cold quickly, and a form that arrives in an inbox nobody checks until tomorrow is money spent on a lead you will not convert. If you are going to pay for attention, be ready to answer it.
What to take from this
There is no honest single figure for what Meta ads cost. There is a range, and where you land inside it comes down to how narrow your audience is, what you are asking for, whether your creative earns attention, when you run, and how much the account has learned.
If someone quotes you a cost per lead before asking what you sell and what a customer is worth, they are quoting an average and hoping. Start from what a customer is worth to you and the budget question answers itself.
