Where the Money Actually Goes: A Straight-Talking Social Media Budget for 2025

Ask ten small business owners what they spend on social media and you'll get ten shrugs. A fiver here on a boosted post, a subscription there, maybe a photographer every few months. It rarely feels like a line item — more like a slow leak.

The trouble is, that leak adds up. And in 2025, with ad costs climbing and every platform nudging you towards a paid button, it's worth sitting down with a cuppa and actually working out where your money should go. So let's do exactly that.

First, the honest baseline

You don't need to spend anything to have a social presence. Plenty of the UK's best-performing small business accounts — the skip hire firm in Leeds, the chippy with 40,000 TikTok followers — were built on a phone and stubbornness. Organic reach isn't dead; it's just harder work.

But at some point, if you want to grow beyond your postcode, money enters the picture. The question is how much, and on what.

Sole traders: £0–£100 a month

If it's just you, a van, and a phone, your budget should be embarrassingly small.

• Scheduling tool: £10–£20 a month. Something like Buffer or Later pays for itself in saved Sunday evenings.
• Boosted posts: £30–£50 a month, maximum. Put it behind your best-performing organic content, not whatever you posted last night at 11pm.
• Everything else: £0. Your camera roll is your content studio.

The biggest waste at this level? Paying for a fancy tool with features you'll never open. You need to post consistently and reply to comments, not generate AI carousels nobody reads.

Growing shops and small teams: £100–£500 a month

Now you've got stock, a shopfront, maybe a couple of staff — and no time. This is where spending starts to make real sense.

• Freelance content creator: £150–£350 a month for a half-day shoot that produces a month's worth of material. A decent local freelancer (there are loads on Instagram, funnily enough) will film, edit, and hand you ready-to-post content.
• Boosting and ads: £100–£200 a month. Even a small, well-targeted budget — think a 15-mile radius, not 'people who like shopping' — outperforms a scattergun approach.
• Tools: £20–£40 for scheduling and maybe a link-in-bio service.

What gets wasted here? Hiring a videographer for cinematic brand films. Lovely to look at, useless for selling. The wobbly phone video of a delivery van pulling up still beats the drone shot every time.

Established SMEs: £500–£2,000+ a month

Once you're at this level, an agency retainer becomes a genuine option. Typical UK small-agency retainers run £500–£1,500 a month for strategy, content, community management, and paid ads.

Is it worth it? Sometimes. A good agency brings structure, reporting, and consistency you can't muster in-house. A bad one brings a monthly PDF full of impressions and no sales. Before signing anything, ask one question: what will this cost me per enquiry, and how will we know?

At this level, budget roughly:

• 50% on content and creative
• 30% on paid distribution
• 20% on tools, reporting, and testing

And keep some budget aside for the odd experiment. £100 on a new format or platform test each quarter is cheaper than a full rebrand when your audience moves on.

What everyone wastes money on

A quick rogue's gallery, because we've seen it all:

• Follower packages. Buying followers is setting fire to cash. Full stop.
• Over-produced video. Polish doesn't sell; personality does.
• Boosting to 'raise awareness'. Awareness of what, exactly? If a boosted post doesn't lead to a follow, a message, or a sale, it's a donation to Meta.
• Too many tools. Three scheduling apps, an analytics dashboard, and a hashtag generator do not equal a strategy.

The one number that matters

Whatever you spend, divide it by the enquiries or sales it generates. That's your cost per customer. A £50 monthly budget that brings in two customers is doing better than a £2,000 retainer that brings in three.

Budget small, measure honestly, and spend on the things that get you closer to a conversation with a real customer. Everything else is just expensive noise in your feed.
