Social media marketing cost is three bills: tools, creative, and media. Here is what each one was in late 2026, and what Omnidemerge actually charges.
People searching “social media marketing cost,” “social media marketing agency,” or “social media marketing services” usually want one number. There are three bills, and mixing them up is how a cheap retainer becomes an expensive month.
1. The tool
Scheduling and inbox software is the small bill. Public list prices move, so treat these as mid-to-late 2026 seat prices, not a quote. A comparison updated 28 October 2026 put Buffer’s approval features from about $12 per channel per month on the Team plan, Sprout Social Professional around $299 per seat, and Hootsuite Advanced around $399 per user. That breakdown is here.
Buy the seat that includes an approval step if more than one person can hit publish. Several of these tools turn on AI replies a tier before they turn on approvals. That is the wrong order for a company that can be quoted in a sales cycle.
2. The creative
This is the fee for thinking and files. It is not the ad budget.
For a B2B creator post, Favikon’s 2026 pricing guide puts most sponsored LinkedIn posts between $200 and $2,000, with a transacted median of $798 across 135 client deals. Their benchmark is here. A single post at the median is not a program. It is one asset. If sales never sends it, it was a sponsorship.
A productized studio fee is easier to compare because the scope is written down. Omnidemerge’s Social Content Pack is $1,200, one time: 12 static posts, 4 short videos, captions, a calendar, one strategy call, and the source files. Retainer Lite is $2,000/mo when you want that cadence every month. Growth is $4,500/mo and quote-only. Full-service is higher and also quoted. None of those prices include media spend.
A US or UK agency will often sell the retainer before a single post has earned a reply. Buy the sprint first. Upgrade when a number moves. That is the same sequence we use for Landing Page + Ads at $2,500, which is the right buy when the missing piece is the page, not the feed.
3. The media
This is the bill that surprises finance. In the first half of 2026, DDMA’s Social Advertising Benchmark, covered by Werf& on 10 November 2026, put LinkedIn at about €18.45 per 1,000 impressions for B2B. TikTok in the same study was about €1.56. LinkedIn’s share of B2B social ad budget in that dataset fell from 52.7% in 2024 to 9.3% in the first half of 2026, across 674,000 campaigns.
Read the shift carefully. LinkedIn did not stop working for pipeline. It got expensive for awareness. More of the budget moved to conversion campaigns and to cheaper networks for reach. If your buyers do not live on those cheaper networks, a low CPM is not a bargain. It is a tax on the wrong room.
Dreamdata’s 2026 LinkedIn ads benchmarks, cited by Perceptric, reported a 121% return on ad spend for LinkedIn in 2025 against 67% for Google Search and 51% for Meta. That is a blended study, not your account. Use it to justify a test with a cap, not a year-long commitment.
How to choose
- Under a few thousand dollars and no page that converts: do not hire a social media marketing company for a vague monthly fee. Buy a defined pack, or a landing sprint, and name the number you will judge.
- A working offer and a person who can publish: Lite is enough until the calendar is the bottleneck.
- Paid on LinkedIn: write the media budget as its own line. Do not hide it inside the studio fee.
- Creators: price the asset and the usage rights. A $798 median post with no right to reuse it in sales is a rental.
