Automating social media with AI costs $0 to about $30 a month for a sole trader using free schedulers and one AI assistant, roughly $40 to $120 for a small business with a paid scheduler, design tool and some automation, and $300 or more on premium suites that charge per seat. Keep 1 to 3 hours a week for review.
The price that matters most is set by how the scheduler charges. Some price per channel, some per user seat, some per "social set" of profiles, and the same three-channel business can pay $15 or $200 a month depending on which model it walks into. The AI writing itself is the cheap part. Messages and replies are where costs start to scale with volume, so decide early whether you are automating posting only, or conversations too.
The five cost lines in any social media automation
- Writing: an AI assistant, or the AI caption feature inside your scheduler.
- Visuals: a design tool, your phone camera, and possibly image or video generation.
- Scheduling: the tool that holds the queue and publishes at set times.
- Glue: automation that moves things between apps, such as a new product in your shop becoming a draft post.
- Conversations: automated replies to comments and direct messages.
Plus a sixth that never appears on a pricing page: the hours someone spends checking and approving. Price all six before choosing tools.
Scheduler prices: per channel, per seat or per set
List prices in USD from each vendor's pricing page, checked in September 2026. Annual billing is usually 15-25% cheaper; confirm on the page, as these change.
| Scheduler | How it charges | Entry paid price | AI included |
|---|---|---|---|
| Meta Business Suite | Free, Facebook and Instagram only | $0 | Meta's own tools |
| Buffer | Per channel | Essentials $5 a channel a month billed yearly; Team $10 a channel with unlimited users | AI Assistant on all plans, including Free (3 channels, 10 queued posts each) |
| Later | Per "social set" (one profile on each network) | Starter $25 a month, or $18.75 billed yearly | 5 AI credits a month on Starter (1 credit = 1 caption); 50 on Growth ($50) |
| Metricool | Per number of brands | Free for 1 brand and 20 posts a month; paid from about $20 a month | AI credits per brand, more on higher plans |
| Hootsuite | Per plan, with user and account limits | Standard $99 a month billed annually, 10 social accounts | AI drafting and recommendations |
| Sprout Social | Per user seat | Essentials $79 a seat billed annually ($99 monthly); Standard $199 a seat | AI assistant features, more on higher tiers |
For a small business with three channels and one person posting, per-channel pricing is usually cheapest: Buffer Essentials for Instagram, Facebook and TikTok is $15 a month on yearly billing. Per-seat suites such as Sprout Social are built for teams that need approvals, shared inboxes and reporting across many profiles; for a shop with one poster, most of that price is unused.
A quick sum shows how much the charging model matters. Take a two-person homeware brand posting to five channels (Instagram, Facebook, TikTok, Pinterest and LinkedIn), with both founders needing access:
- Buffer Team at $10 a channel billed yearly, unlimited users: 5 x $10 = $50 a month.
- Later Growth at $50 a month: 2 social sets and 2 users, so covered at $50 (or $37.50 billed yearly).
- Sprout Social Standard at $199 a seat: 2 x $199 = $398 a month.
Same channels, same people, an eightfold spread. The premium suite adds a shared inbox, approvals and deeper reports; whether those are worth $350 a month depends on how many messages you handle, not on the AI.
What the AI part costs
There are two ways to pay for the writing, and many businesses use both.
- A general assistant: ChatGPT Plus or Claude Pro at $20 a month, or the free tiers with tighter limits. Best for writing a week of posts in one go from your own notes, because you can keep your brand voice guide and product details in a Project.
- The scheduler's built-in AI: included in the plan price but often rationed. Later's Starter plan includes 5 AI credits a month, enough for five captions. Buffer includes its AI Assistant on all plans. Useful for quick rewrites inside the queue.
The AI cost is small either way. Where money leaks is image and video generation, which runs on credits that are easy to burn through: a single generated video clip can use a noticeable share of a monthly allowance. Budget for it only if you will actually post generated visuals.
Three budgets built line by line
| Line | Lean (sole trader) | Mid (small shop) | Premium (small team) |
|---|---|---|---|
| Writing | Free assistant tier, or $20 | $20 (Claude Pro or ChatGPT Plus) | $50 (two ChatGPT Business or Claude Team seats, annual) |
| Scheduling | $0 (Meta Business Suite) | $15 (Buffer Essentials, 3 channels, yearly) | $199 (one Sprout Social Standard seat) or $99 (Hootsuite Standard) |
| Design | Free design tier and phone photos | Paid Canva plan (price varies) | Paid Canva seats for two |
| Glue automation | $0 | $9 (Make entry plan) or $19.99 (Zapier Professional, yearly) | $20-$30 |
| DM replies | Manual | Manual, or about $10-$15 on a per-message AI agent | Tens of dollars on a DM tool, scaled by contacts |
| Cash a month | $0-$20 | About $55-$75 plus design | About $200-$300 plus design |
| Human review a week | 2-3 hours | 1.5-2 hours | 1-1.5 hours per poster |
A toy shop's setup, costed
An illustrative example. An independent toy shop posts five times a week on Instagram and Facebook, three times on TikTok, and gets around 300 direct messages a month, mostly "Do you have this in stock?" and "What time do you close on Sunday?".
Before: the owner writes each post on her phone after closing, about 20 minutes each, so roughly 4.5 hours a week. Messages get answered in the evening, sometimes the next morning.
After, month by month:
- Claude Pro, $20. A Project holds the shop's voice guide, age-range rules and opening hours. Every Monday she pastes in the week's new stock and events and gets 13 draft posts in one go.
- Buffer Essentials for three channels, $15 on yearly billing. The drafts go into one queue with images from her phone.
- Zapier Professional, $19.99 on yearly billing. When a new product is added to the online shop, a Zap asks an AI step for a caption and saves it as a Buffer draft for her to approve. The shop adds about 30 products a month. With an AI step at 1 to 5 tasks per run depending on the model tier, plus one task for the Buffer action, that is roughly 60 to 180 tasks, well inside the 750 included. The free Zapier plan would not work here: it only allows two-step Zaps and 100 tasks a month.
- DM replies via Meta's Business Agent, about $12-$15. At Meta's own estimate of roughly 4 to 5 cents a message, 300 messages cost about $12 to $15. She limits it to stock and opening-hours questions and hands everything else to herself.
Total: about $67 to $70 a month in cash. Her time drops to roughly 1 hour on Monday for drafting and approving, plus 10 minutes a day on messages the agent passed to her. That is around 2 hours a week, down from over 6 including messages.
The sample batch prompt she uses, and an illustrative slice of the output:
Using the shop voice guide in this Project, write this week's posts.
New stock: magnetic building tiles (age 3+, $38); pirate ship
playset (age 4+, $54). Events: Saturday story time 11am.
Closed Monday for stocktake.
Write: 5 Instagram/Facebook posts, 3 TikTok caption ideas with a
one-line video description each. Flag anything you had to assume.Illustrative output extract: "Story time is back this Saturday at 11. Bring a cushion, we'll bring the pirates..." and a flagged assumption: "I assumed story time is free. Please confirm." The flag was right; it's free for under-fives only. That single correction is why the approval step stays.
Paying for automation between apps: when it's worth it
Glue automation earns its $9 to $30 a month when it removes a step you do many times a week. Good candidates:
- A new product in your online shop becomes a draft post (as above).
- Five-star review becomes a "customer quote" draft for approval.
- An event added to your calendar becomes a reminder post two days before.
Poor candidates: anything that posts without approval, and anything you do once a month. A charity shop that posts twice a week from volunteers' photos gains nothing from Zapier; a shared phone album, Meta Business Suite and a free assistant tier cover the whole job at $0. If the charity wants a shared assistant with a saved voice guide, check whether it qualifies for nonprofit pricing: OpenAI lists ChatGPT Business Standard seats for nonprofits at $8 a user a month on annual billing. Its only real cost is the volunteer hour, which is better spent photographing the items than configuring tools.
A weekly routine that keeps the bill and the hours down
Batching is what makes the cheaper tiers work: one session a week uses fewer AI credits, less automation and less attention than posting on the fly. A filled-in routine for the toy shop above:
| When | Task | Tool | Time |
|---|---|---|---|
| Monday 9:00 | Paste new stock, events and dates into the Project; generate the week's drafts | Claude Pro | 15 min |
| Monday 9:15 | Edit drafts against the pre-publish checklist; fix prices, ages and dates | Checklist | 25 min |
| Monday 9:40 | Attach photos, load the Buffer queue, approve Zapier-created product drafts | Buffer | 20 min |
| Daily, 10 min | Answer DMs the agent handed over; reply to comments | Instagram and Facebook inboxes | 70 min a week |
| Friday 16:00 | Check the sent list for failed posts; note the two best and worst posts | Buffer analytics | 10 min |
Editing is where AI drafts earn or lose their keep. An illustrative before and after from the Monday session:
Before: "Spark your little one's creativity with our amazing new magnetic building tiles! Perfect for all ages, these tiles provide endless hours of fun and learning. Shop now!"
After: "New in: magnetic building tiles, $38 for a 60-piece set. For ages 3 and up, as the pieces are small enough to need a watchful eye below that. We've built a rocket, a garage and a very wobbly castle on the counter. Come and try them before you buy."
The draft claimed "perfect for all ages", which contradicts the 3+ age mark on the box, and said nothing only this shop could say. The edit took two minutes, fixed a claim that matters for a toy retailer, and gave people a reason to visit.
Costs that don't show on pricing pages
- Channel creep. Per-channel pricing is cheap at three channels and less so at eight. Adding Pinterest, Threads and LinkedIn "because the scheduler supports them" can double the bill without doubling sales.
- AI credit caps. A plan with 5 AI captions a month pushes you to a higher tier or a separate assistant sooner than you'd think.
- Seat charges. Adding a part-time helper to a per-seat suite can add $79 to $199 a month.
- Per-message AI replies. Conversation costs rise with success. A viral post that brings 2,000 messages costs about $80 to $100 at 4 to 5 cents each.
- Account risk. Aggressive DM automation can breach platform rules. See what gets Instagram accounts banned before switching it on.
- Failed posts. Scheduled posts sometimes fail when a platform token expires. Someone has to notice and republish, which is why a weekly check of the "sent" list belongs in the routine.
The hours no tool removes
A sports equipment shop that automated everything except review found out why review matters: an AI-drafted post announced "20% off all rackets" when the offer was on one brand only. Nobody checked the queue that week. The shop honoured the discount for the customers who asked, which cost more than a year of scheduler fees.
Build the review into the budget: roughly 5 minutes a post for a quick read against a pre-publish checklist, plus 15 minutes a week scanning results. For a business posting 13 times a week, that is about an hour and a quarter. It is the cheapest insurance in the whole stack. And if you are tempted to remove it entirely, read what breaks when AI runs social media on autopilot.
Checking the spend is worth it after a month
Four numbers tell you whether the stack is paying for itself, and none needs special software. Write them down for the month before you switch anything on, then again four weeks later:
- Hours a week on social media, including messages. The toy shop went from about 6 to about 2.
- Posts published versus planned. Automation should close the gap between the two; if it doesn't, the bottleneck is photos or approval, not writing.
- Median reply time to messages. If an AI agent is answering, this should fall sharply without a rise in complaints.
- Enquiries or visits you can trace to social, even roughly: "saw it on Instagram" at the till counts.
If hours fell and the other three held steady or improved, the spend is justified. If only the post count rose, you have paid to publish more of the same.
Ways to cut the bill without cutting quality
- Start with Meta Business Suite if Facebook and Instagram are your main channels, and add a paid scheduler only when a third platform earns it.
- Pay for one general assistant, not AI add-ons in three separate tools.
- Batch drafting into one weekly session, which needs fewer AI credits and less of your attention.
- Choose yearly billing only after three months on monthly billing, once you know the tool fits.
- Cap automated DM replies to the three or four questions that make up most of your messages.
- Review the stack every six months and cancel anything that has not been opened in the last month.
Social media automation cost questions
Is Meta Business Suite enough to schedule posts for free?
For Facebook and Instagram, often yes. Meta's own planner lets you schedule posts and stories to both at no cost. It does not cover TikTok, LinkedIn or Pinterest, and it gives you no shared queue across platforms. If Facebook and Instagram are your only channels, start there and pay for a scheduler only when you add a third platform or need approvals.
Do AI caption features in schedulers replace ChatGPT or Claude?
For quick captions, they can. The limits are the catch: some schedulers ration AI use with monthly credits, and the built-in writer rarely knows your products or voice as well as a Project in ChatGPT or Claude loaded with your brand guide. Many small businesses draft in a general assistant and use the scheduler's AI only for small rewrites.
How much does it cost to have AI answer Instagram and Facebook messages?
It depends on the tool. Meta's own Business Agent has charged per token since 1 August 2026, which Meta puts at roughly 4 to 5 cents a message with no free allowance. Third-party DM tools usually charge a monthly fee that rises with your number of active contacts. Price your real monthly message volume, and keep a person on anything involving complaints or refunds.
