There is no single price for Facebook ads. You set your own budget, and Facebook charges you based on the results you ask for, such as clicks or impressions. Most UK small businesses we speak to start somewhere between £300 and £1,000 a month on ad spend, then adjust once they see what a customer is actually worth to them.
What you pay per result depends on your industry, your audience, your creative and how much competition there is for the same people. To give you a working idea: many UK small businesses see a cost per click roughly in the region of 30p to £1.50, and a cost per thousand impressions (CPM) somewhere around £5 to £15. These are ballpark ranges to plan with, not promises. Your numbers will settle once your ads have run for a few weeks.
Key point: You control the budget. Facebook controls the price per result. Start small, measure what a lead or sale costs you, then scale the winners.
What actually makes up the cost
When people ask how much Facebook ads cost, they usually mean two different things: the total you spend, and the price of each result. Both matter.
Your total spend is your daily or lifetime budget. You choose it. If you set £15 a day, that is £15 a day, no surprises. The price per result is set by an auction. You are bidding against other advertisers who want to reach the same audience, so the cost moves up and down.
The main things that push the price up or down
Audience
Tight, high-value audiences in busy sectors cost more to reach. Broad, less competitive audiences usually cost less.
Creative quality
Ads people actually engage with get shown more cheaply. Weak images and dull copy cost you more for the same reach.
Your objective
Asking for a purchase costs more per result than asking for a click. You are asking for a bigger commitment.
Season and competition
Costs climb when more advertisers pile in, such as the run-up to Christmas or big sale periods.
Realistic UK benchmarks to plan with
Use the table below as a starting reference. Every account differs, so treat these as planning figures rather than a quote.
| Metric | Typical UK small business range | What it tells you |
|---|---|---|
| Cost per click (CPC) | Around 30p to £1.50 | What each visit to your site costs |
| Cost per 1,000 impressions (CPM) | Around £5 to £15 | What it costs to be seen 1,000 times |
| Cost per lead | Varies widely by sector | What a form fill or enquiry costs |
| Sensible starting monthly spend | £300 to £1,000 | Enough data to learn without gambling |
Notice the last row. Below roughly £300 a month, Facebook often struggles to gather enough data to optimise, so results stay patchy. You are not really testing your ads, you are starving them.
How to set a budget that makes sense
Forget picking a number out of the air. Work backwards from what a customer is worth to you.
- Know your average customer value. If a new customer is worth £200 to you, you can afford to spend a fair bit to win one.
- Decide your target cost per sale. Say you are happy spending up to £40 to win a £200 customer. That is your line in the sand.
- Estimate the steps in between. If roughly one in five leads becomes a customer, and you are aiming for a £40 cost per sale, you can afford around £8 per lead.
- Set a test budget. Give Facebook enough spend to produce at least a handful of leads a week so you get real data. For many small businesses that means £15 to £30 a day.
- Run for at least two to four weeks. Judge on cost per lead and cost per sale, not on likes.
Once you know your real cost per sale, scaling is simple maths. If every £40 reliably brings in a £200 customer, spending more is an easy decision. If it does not, you fix the offer, the targeting or the creative before you add money.
Key point: A budget is not a cost, it is an investment you judge against the value of a customer. Measure cost per sale, not cost per click alone.
Don't forget the management cost
Your ad spend is money that goes to Facebook. That is separate from the cost of someone setting up, running and improving your campaigns. You can do this yourself, but it takes time to learn and it is easy to waste budget while you do.
If you bring in an agency, you are paying for the strategy, the setup, the ongoing testing and the reporting. At DPOM our Facebook ads management services run on a fixed monthly fee starting from £145 per month, so you always know the management side of the cost up front. Your ad spend sits on top of that and stays entirely under your control.
Common ways small businesses waste money
- Boosting posts instead of running proper campaigns. Boosting is quick but blunt. We cover the difference in Facebook ads vs boosted posts.
- Targeting too broad or too narrow. Both waste spend. Building on your existing customers with lookalike audiences is usually a stronger start.
- Changing things too often. Editing an ad every day resets the learning and wastes budget. Give it room.
- Ignoring the landing page. The cheapest click in the world is wasted if the page it lands on does not convince anyone.
- No tracking. If you cannot see which ad produced which enquiry, you cannot control your cost.
Facebook or Instagram, or both?
Facebook and Instagram share the same ad platform, so your budget can run across both. Costs and results differ by audience and product. If you are weighing up where your money should go, our guide on Instagram ads vs Facebook ads walks through it in plain terms.
For a deeper look purely at pricing, our companion piece, the UK small business guide to Facebook ad costs, goes further into the numbers.
Working out the right budget for your business
Facebook ads cost whatever you set as your budget, with the price per result decided in an auction. For most UK small businesses, £300 to £1,000 a month is a sensible starting point, and the real question is not "how much do they cost" but "what is a customer worth to me". Work backwards from that, measure your cost per sale, and scale what works. If you would rather not learn the platform the hard way, our Facebook advertising services handle the setup, testing and reporting for a fixed monthly fee from £145 per month, with your ad spend staying under your control. We are a UK agency with 15 years behind us, we are a Google Partner, and every meeting is a straightforward video call. Get in touch and we will help you set a budget that fits your goals.
