Straight answer: most small businesses need £500 to £1,500 a month to run Facebook ads with any real chance of getting usable data, and that’s before you pay anyone to manage the account for you. The platform will happily take £5 a day off you forever without ever telling you it’s not enough to learn anything. That’s the bit nobody puts in the headline.
The number everyone asks me first
Every client meeting, someone asks “how much do I need to spend on Facebook ads?” as if there’s one figure. There isn’t. I’ve run campaigns for a jewellery brand in Manchester on £40 a day and I’ve sat in on accounts spending £30,000 a month for a SaaS company. Both were “running Facebook ads.” The costs behave completely differently depending on your industry, your offer, and how competitive your audience is.
What I can give you is the honest range, based on what I’ve watched happen inside ad accounts, not what a Meta rep tells you on a sales call.
What I spent last quarter, line by line
I’ll use a real example because vague ranges don’t help anyone plan a budget. A client of mine, a small handmade jewellery brand based near Manchester, came to me spending £15 a day on boosted posts and wondering why nothing sold. We restructured the account and this is roughly what the numbers looked like over the following three months:
- Daily ad spend: £45, so around £1,350 a month
- Average CPM (cost per thousand impressions): £11.20
- Average cost per click: £0.68
- Average cost per purchase: £18.40
- Average order value: £52
- My monthly management fee: £600
So the true monthly cost of “running Facebook ads” for this client was £1,950, not £1,350. That gap between ad spend and total cost is the part almost every beginner underestimates. The platform doesn’t charge you for management. A person does, and that person’s time is not free, whether it’s you doing it at 11pm instead of sleeping or someone like me doing it for a fee.
The three costs nobody separates
When people ask what Facebook ads cost, they’re usually only thinking about one of three separate costs. Split them out and the picture gets much clearer:
- Ad spend itself, the money Meta takes directly. This is the only cost most calculators show you.
- Creative production, photos, video, copy, design. A single decent video ad from a freelancer runs £150 to £600. A batch of static images from a designer is often £30 to £80 each.
- Management time, whether that’s your own hours or a freelancer or agency fee. Agencies typically charge either a flat monthly retainer of £500 to £3,000 or a percentage of spend, usually 10% to 20%.
Miss one of those three and your budget will always feel wrong. I’ve had business owners tell me Facebook ads “don’t work” when what happened is they spent £300 on ad spend and £0 on creative, so they were running the same tired photo of their product for six weeks straight while the audience got bored of it. The platform punishes stale creative with rising costs. That’s not Facebook being unfair, that’s just what happens when the same 2,000 people see your face nine times.
How much you need to spend before the data means anything
Here’s the part that frustrates people the most: Facebook needs roughly 50 conversions per ad set within a week to exit the “learning phase” and start optimising. If your cost per conversion is £20, that means you need to spend around £1,000 per ad set per week just to get out of the noisy, unreliable early stage.
Most small businesses can’t afford to run five ad sets like that at once, and they shouldn’t try to. A more realistic starting point:
- Pick one offer and one audience. Not three of each.
- Set a daily budget of £20 to £30 minimum, run it for 14 days without touching it.
- Track cost per lead or cost per purchase weekly, not daily. Daily numbers on a small budget bounce around too much to mean anything.
- After two weeks, kill what’s clearly not working and double down on what is.
- Only scale spend by 20% at a time, big jumps reset the learning phase and your costs spike again.
That whole process costs roughly £280 to £420 in ad spend before you know if the offer even works. If your budget can’t stretch to that, you’re better off spending on organic reach and content first, building the kind of engaged audience I’ve written about in how much a Facebook group is worth in real numbers, before you put money behind ads.
Agencies, freelancers, and doing it yourself
I get asked constantly whether it’s worth paying someone to manage Facebook ads. Here’s what the market looks like in 2026:
- Freelancers typically charge £300 to £800 a month for accounts spending under £3,000, or an hourly rate of £35 to £75.
- Small agencies often charge a flat fee of £750 to £2,500 a month, or 15% of ad spend, whichever is higher.
- DIY costs you nothing in fees but eats 4 to 8 hours a week if you’re doing it well, more if you’re learning as you go.
I’d say do it yourself if your ad spend is under £500 a month, the fees won’t be proportionate. Hire someone once you’re spending £1,500 or more a month and your own time is worth more spent elsewhere in the business. If you want a proper look at what that support costs and when it’s worth it, I’ve broken the whole thing down on my page about what an AI consultant costs, since a lot of the same logic applies to any specialist help you bring in.
Where the real money leaks
Nobody talks about this enough: the biggest waste in most Facebook ad accounts isn’t the ad spend, it’s tracking that’s broken. If your pixel or Conversions API isn’t set up correctly, Meta’s algorithm is optimising for the wrong signal, and it will happily spend your budget finding people who look like your worst customers instead of your best ones.
I’ve opened accounts where the client had been running ads for eight months and the pixel had been firing on the wrong page for six of them. That’s not a small mistake, that’s months of ad spend teaching the algorithm to find the wrong audience. If you’re sending leads anywhere near a CRM, it’s worth getting your tracking checked, and I’ve written a full guide on setting up CAPI without the usual headache that covers exactly this.
Also check the basics. I’ve had clients whose ads were technically running but whose page kept timing out for visitors clicking through, which quietly kills conversion rate and inflates your real cost per sale. If that sounds familiar, it’s worth reading why your Facebook page might not be loading before you blame the ad itself.
Why your cost per lead probably doubled and nobody warned you
This is the bit that most articles about ad costs skip entirely. Since Apple’s privacy changes in 2021, cost per lead and cost per conversion have risen sharply across most industries, in some cases by 80% to 120% compared to before. Meta lost a huge amount of its tracking ability overnight, and the platform has spent every year since rebuilding that visibility through Conversions API, aggregated event measurement, and broader targeting that relies far more on its own algorithm than on precise audience data you control.
What that means for you in plain terms: the £5 cost per lead your friend got in 2019 is close to fiction now for most B2C offers, and anyone selling you a course promising those numbers in 2026 is either lying or talking about a tiny, low-competition niche. I’d rather tell you that upfront than have you set a budget based on someone’s screenshot from five years ago and feel like a failure when your numbers don’t match.
The uncomfortable part underneath that is this: a lot of agencies know this and still price their retainers as if 2019 costs are normal, then blame “the algorithm” or “the market” when results underperform. Ask any agency you’re considering for their actual client cost-per-result benchmarks from the last three months, not a case study from years ago. If they can’t give you that, walk.
Creative costs more than people plan for, and it should
Of every pound spent on Facebook ads, I’d put roughly 60 to 70% into media spend and the rest into creative and testing, not the other way round. Most beginners flip that ratio, spending almost everything on the ad itself and using one photo taken on a phone. The algorithm rewards fresh, varied creative, so budgeting for three or four ad variations a month isn’t a nice extra, it’s part of the real cost of running ads that work.
If your budget is tight, there are useful free and low-cost tools worth knowing about, and I’ve listed a set of them, no trials, no hidden upsells, in 30 free business tools that don’t try to upsell you later. For anything more involved, like video editing or AI-assisted creative production, my rundown of what’s worth paying for in a content creation stack in 2026 will save you buying software you won’t use past month one.
A realistic monthly budget by business size
- Solo business or startup: £300 to £600 ad spend, DIY management, one or two creative refreshes a month. Total real cost: £350 to £700.
- Small business, 2 to 10 staff: £1,000 to £2,500 ad spend, freelancer or part-time management at £400 to £800, occasional paid creative. Total real cost: £1,500 to £3,500.
- Established business, ready to scale: £5,000 to £15,000 ad spend, agency retainer at 10 to 15% of spend, dedicated creative budget. Total real cost: £6,000 to £18,000.
Those ranges hold up across most sectors I’ve worked in, from ecommerce to B2B lead generation, though anything with a long sales cycle or high average order value can justify spending at the top of a bracket even while the business is small.

Frequently asked questions
What’s a realistic minimum daily budget for Facebook ads?
I’d set £15 to £20 a day as the true minimum for a small business, run for at least two weeks without changes, giving you £210 to £280 to see whether an offer has any traction before deciding to scale or stop.
How much do Facebook ad agencies charge in 2026?
Most agencies charge either a flat monthly retainer of £750 to £2,500 or a percentage of ad spend, typically 10% to 20%, whichever is higher, so a £3,000 monthly ad spend often carries a management fee of £450 to £600 on top.
Why did my cost per lead suddenly increase so much?
Apple’s privacy changes reduced Meta’s tracking accuracy, and costs across most industries rose by 80% to 120% compared to before 2021, so higher costs today usually reflect the wider platform shift rather than something you’re doing wrong.
Can I run Facebook ads without paying for management?
Yes, if your monthly spend is under roughly £500, managing it yourself makes financial sense since agency and freelancer fees wouldn’t be proportionate to the spend, though expect to invest four to eight hours a week learning and reviewing your account.
