The short answer: a solo founder in 2026 can run social media for $0 plus several hours a week, for about $20 to $40 a month in software plus fewer hours, or for a freelancer or agency retainer that you should price by collecting quotes rather than trusting published averages. The software line is the small line. The hours are the real bill.
This guide prices four realistic stacks with first-party sources, then gives you a two-line formula for the time cost, because a $0 stack that eats four hours a week is not free. Every vendor price below was reviewed on August 26, 2026 against the vendor's own page, and the one number this guide refuses to print is the one nobody publishes honestly: what an agency charges.
The four stacks, priced
One honesty note on the agency row: plenty of blog posts publish confident 'average social media management pricing' figures. The ranges vary wildly by country, scope, and seniority, and none of the numbers we found trace to a first-party source we could cite, so this guide will not print one. Ask two or three providers for a quote scoped to your exact channels and posting volume; that hour of email produces a better number than any listicle.
| Stack | Software per month | Where the time goes |
|---|---|---|
| DIY free: native apps, or Buffer Free for up to 3 channels | $0 | Writing every post, adapting it per platform by hand, publishing from queues capped at 10 posts per channel |
| General AI plus scheduler: ChatGPT Plus and Buffer Essentials at 3 channels | $38 ($20 + $18) | Re-briefing ChatGPT each session, pasting drafts into the scheduler, checking lengths and links by hand |
| Creator specialist: Typefully Creator or Hypefury Full | $16 to $19 | Writing in the tool; strong for X-first creators, thinner for community channels like Reddit or Discord |
| Cadencz: Solo or Founder | $19 or $39 | Reviewing and approving drafts written from your stored product context; Founder covers 7 channels with two accounts on each |
| Freelancer or agency | Get quotes | Briefing, reviewing, and approving on someone else's schedule; quality tracks the brief you write |
The time cost, in two lines
Estimate your weekly hands-on hours: sourcing ideas, writing, adapting per platform, scheduling, and checking that posts went out. Then multiply: weekly hours times 4.3 gives monthly hours, and monthly hours times what an hour of your time is worth gives the real bill.
- Worked example, with assumptions you should replace: 4 hours a week at $75 an hour is 17.2 hours and roughly $1,290 a month of founder time on the $0 stack.
- If a $38 stack cuts that to 2 hours a week, it saves about $645 of time for $38 of software in this example.
- If a tool does not reduce hours or raise output quality, its price does not matter; cancel it.
- Recount every quarter. Time costs drift as your channels and volume change.
Cost per post, when a tool publishes its allowances
Where a vendor publishes hard allowances, you can turn the subscription into a per-unit price and compare like with like. Cadencz Solo at $19 includes 150 shared AI generations a month, which works out to about 13 cents per generation if you use them all; Founder at $39 includes 600, about 6.5 cents each. That is arithmetic on published allowances, not a promise that any generation becomes a good post, and unused allowance makes the real unit price higher.
Run the same division on whatever you evaluate. A tool with no published limits cannot be unit-priced, which is worth noticing in itself, and a cheap subscription you barely use has a terrible cost per post.
How to get a real agency or freelancer quote
- Name the exact channels and accounts, the posts per week on each, and who supplies the raw material, because a provider who invents your product stories is a risk, not a service.
- Ask what is in the retainer and what bills separately: strategy, design, community replies, reporting.
- Ask for the approval flow and turnaround: who sees a draft before it publishes, and how fast revisions come back.
- Ask about contract length, notice period, and who owns the accounts and content when you leave.
- Get the same scope quoted by two or three providers; the spread between quotes tells you more than any published average.
When each stack is the right call
- Stay at $0 while you are proving the habit: if you have not posted twice a week for a month, no purchase fixes that.
- Buy the general AI plus scheduler stack when you post to 3 or fewer channels and enjoy driving the writing yourself; ChatGPT Plus lists at $20 and Buffer Essentials adds $6 per channel monthly.
- Buy a creator specialist when X or LinkedIn is the whole game and you want the editor and growth mechanics; Typefully Creator lists at $16 and Hypefury Full at $19.
- Consider Cadencz when re-explaining your product before every draft is the recurring cost: the Product Brain stores that context once, and drafts arrive for approval instead of from a blank prompt.
- Hire out when your hours are worth more than the retainer and you can still spare time for briefs and approvals, because those stay with you.
The mistakes that inflate the bill
- Paying for overlapping tools: an AI subscription, a scheduler, and a specialist tool that all draft posts is one drafting bill too many.
- Buying capacity instead of habit: a 10-channel plan does not create a 10-channel publishing rhythm.
- Ignoring the approval trail: a mispost costs more than a year of software, and neither ChatGPT nor a bare queue keeps a record of who approved what.
- Counting only cash: the founder who 'saves' $19 a month by hand-adapting every post to five platforms is usually spending $200 of time to do it.
Decide, then revisit quarterly
Write down your channel count, weekly hours, and monthly software spend today. Pick the cheapest stack that removes your largest named cost, run it for a quarter, and remeasure. Moving up a tier is justified by a recurring cost it removes, never by a feature list.
The per-channel math behind the Buffer rows is worked through in detail in the Buffer cost post, and the ChatGPT-only workflow, including when it is genuinely enough, has its own honest guide.
