What a Social Media Manager Actually Costs Per Post in the UK (2026)

A monthly retainer tells you what you will spend, not what you will get. The same is true of a day rate or a salary. To compare them fairly you have to divide each one by the output it actually buys, and almost nobody publishing UK rate guides does that division for you.

This article does. It takes the social media management cost per post in the UK for each hiring model, freelancer, agency, in-house and software, and reduces every option to one comparable number. If you want the broader picture of what each model involves day to day, our full UK cost comparison of freelancers, agencies and in-house hires covers that. This page is only about the maths.

Why cost per post is the honest unit

Every hiring model prices itself in a different currency. Freelancers quote hours or days. Agencies quote monthly retainers. An employee costs a salary plus on-costs. None of these numbers can be compared directly, which suits everyone selling them.

What you are actually buying, in most small-business arrangements, is published posts plus the thinking behind them. So the useful question is not "what does this cost per month" but "what does this cost per post that actually goes live". Once you ask it that way, some options look much better value than their headline price suggests, and some look much worse.

Throughout this piece we assume an output of 12 posts a month, roughly three per week, which is a sensible working cadence for a small B2B firm on one platform.

The raw rates, with sources

Start with the underlying prices before any division.

• Freelancer hourly rates. Wise's UK guide to social media manager rates quotes a wide spread, from roughly £15 an hour at the junior end to £50 or more for experienced managers.
• Freelancer day rates. YunoJuno's freelancer rate reports, drawn from real bookings on its marketplace, have put typical day rates for social media freelancers around the £300 mark, with senior specialists charging comfortably above that.
• Agency retainers. UK retainers for small-business social media management commonly fall between about £300 a month at the budget end and £1,500 or more for a fuller service with strategy and reporting.
• In-house salary. Advertised UK social media manager salaries typically sit somewhere between the high twenties and mid thirties of thousands. Add employer National Insurance, pension and overheads and the true annual cost is meaningfully higher than the salary line.

Social media management cost per post in the UK: the table

Now divide each of those by 12 posts a month, using realistic assumptions about how much time the work takes.

Two things jump out. First, the cheapest agency retainer and a modest hourly freelancer overlap almost completely, which is why so many small firms bounce between the two without feeling much difference. Second, in-house only looks expensive because we pro-rated it generously. Hire someone full time to run one LinkedIn page at 12 posts a month and you are paying something like £250 per post, which is why almost nobody does that.

What pushes the per-post price up

The per-post number is not just writing time. Four things inflate it, and knowing which ones you actually need is how you avoid paying for the ones you do not.

Strategy and planning

Someone deciding what the posts should be about, not just writing them. Agencies bake this into the retainer whether you use it or not. For a small firm with an obvious story, the work you do, the problems you solve, the questions clients ask, heavyweight strategy is often the most skippable line item.

Design and visuals

Branded image cards and carousels take real time when made by hand. A freelancer who designs as well as writes will charge nearer the top of the hourly range, and design-heavy agency packages sit in the upper retainer bands.

Community management

Replying to comments and messages is genuinely valuable but it is a separate job from content creation. If a retainer includes it, part of your per-post price is actually paying for inbox coverage. Price them separately in your head.

Reporting

Monthly decks are where a surprising amount of retainer time goes. Ask yourself whether you would act differently based on the report. If not, you are paying per-post money for a PDF.

When software undercuts all three

The reason human-made posts cost £25 to £60 each is that a person spends time on every single one. Software that creates the posts, not just schedules them, breaks that link between output and hours.

This is a different category from Buffer or Hootsuite, which hold and publish posts you still have to create. A done-for-you tool reads your website, gathers raw material from your team, drafts in your voice, builds the images, and sends everything to a named person for approval before publishing. The human effort per post drops to a few minutes of review rather than an hour of creation, and the per-post cost drops with it. We have written separately about what done-for-you LinkedIn services actually include at each price point if you want that landscape mapped.

On honesty: Helio Posts is free during early access, so its current cost per post is genuinely zero. That will not last forever. Future pricing is planned per brand run, and the pricing page states the current position plainly. Even priced, the model only makes sense if it lands well under the £25 floor of human-made posts, because that is the comparison every buyer will make.

How to use these numbers

Work backwards from the output you actually need. Decide your cadence first, 12 posts a month is a reasonable default for a single platform, then multiply by the per-post figures above to see what each model should cost you. If a quote works out at £100 per post, that is not automatically bad, but the extra money should be visibly buying strategy, design, community management or reporting that you genuinely want.

And if the honest answer is that you need consistent, competent posts on one platform and nothing more, the per-post maths now points somewhere it did not five years ago: pay a human to approve, not to create.
