How much does a marketing agency cost? Real ranges, and what sits behind them
Between $500 a month for a freelancer and $10,000 for a full-service agency, with most small businesses landing at $1,500 to $3,500 for a local agency on a six to twelve month contract. Below: what each tier includes, what a retainer is actually made of, five questions to ask before you sign, and what the same work costs when software does the hours.

What a retainer is made of
Take a $3,000 a month retainer at a small agency. After margin, management and sales cost, it buys roughly 20 to 25 hours of staff time a month, spread across an account manager, a strategist who appears quarterly and a junior who does most of the production. That is five or six hours a week on your business, which is about what an office manager can give it.
The second component is tools. An agency runs an $800 to $2,000 a month stack: SEO software, a scheduler, a design tool, an email platform, a reporting tool, a project tool. Every client pays a slice of it. The third component is the term. Six to twelve months is standard because the first two months go on onboarding and setup, and the agency needs the rest to recover them. That is also why leaving early is expensive and why the website is often built on the agency's builder.
None of this makes agencies dishonest. It makes them priced for their own costs rather than for the work a small business needs. When software does the audits, drafts, pages, designs and reports, the hours get cheap, the tool stack collapses into one workspace, and the term disappears because there is nothing to recover.

Marketing agency pricing by tier
Typical US monthly figures for a small business in 2026. Ad spend sits on top of every row, and ad management is often priced separately at 10% to 20% of spend.
| Option | Typical monthly cost | What you get |
|---|---|---|
| Freelancer, one channel | $500 to $2,000 | One person doing SEO, social, content or ads well, part time, with their own tools. You coordinate everything else. |
| Small local agency | $1,500 to $3,500 | Website, SEO and social for one location, a monthly report, a kickoff strategy, a six to twelve month contract. |
| Mid-sized full-service agency | $3,000 to $10,000 | Strategy plus execution across several channels, a dedicated account team, quarterly reviews, a twelve month contract. |
| Fractional CMO | $3,000 to $8,000 | Two to eight days a month of senior strategy and oversight. Execution and tools are extra. |
| In-house marketing manager | $5,000 to $8,000 | One salary fully loaded, plus $800 to $1,500 of tools, for someone who still needs contractors for design and development. |
| Brainito AI marketing manager | $20 to $500 | Weekly audit, monthly strategy, website builder, SEO, social, email, analytics, team chat, tasks, contacts and 300+ tools. Dashboards free, credits only for work that runs. |
Agency, freelancer and salary ranges are what small businesses report paying in 2026 and vary by market and industry. The Brainito figure is what businesses on the platform typically spend. The $500 AI Marketer plan is 20,000 credits a month with a dedicated human marketing manager.
What the retainer is supposed to cover, and what Brainito includes
Use this as the checklist when you read an agency proposal. All eleven are in one Brainito workspace.
Weekly marketing audit
77 factors across SEO, speed, conversion, content and AI visibility, re-run every week, with the evidence behind each verdict. Agencies run one at onboarding.
Monthly marketing strategy
A plan built from the audit, your business and your numbers, rewritten each month. Agencies write one at the kickoff and review it quarterly.
Website builder
A real site from a brief, previewed at brainito.com/your-domain, edited by clicking, published to your own GitHub and Vercel. Agencies charge $3,000 to $15,000 for a build.
SEO management
On-page fixes per page, a technical audit, directories and citations, and a check on whether AI assistants cite you. Usually $750 to $2,000 a month on its own.
Social media management
Drafts, designs, approval on the post, scheduling. Usually $500 to $1,500 a month on its own.
Email automation
Campaigns, follow-up sequences and segments from the same contact list the site feeds. Usually $300 to $1,000 a month plus the platform.
Analytics and ads reporting
Google Ads, Meta, organic, email and referrals on one page, updated hourly. Agencies send a monthly PDF.
Team chat
Talk to your team or whoever helps inside the workspace, next to the work, instead of email threads with an account manager.
Task management
Every module writes to one board: audit fixes, plan steps, posts to approve, with categories, dates and history.
Contacts, a mini CRM
Leads from the site, email subscribers and customers in one list, segmented for email and follow-up.
300+ marketing tools
Keyword research across fifteen platforms, meta tags, schema, UTM links, headline tests and more, most of them free. This is most of the agency's tool stack.
Five questions to ask any agency
Ask them in the first call. The answers tell you what the retainer is really buying.
How many hours a month, and whose?
Ask for the hours behind the fee and the seniority of the people delivering them. If the answer is vague, assume 20 to 25 junior hours at $3,000.
What is the minimum term and why?
Six to twelve months is normal. Ask what the onboarding fee covers and what happens to the work if you leave at month four.
Who owns the website, the accounts and the data?
The site should be in your hosting or your repository, the ad and analytics accounts in your name, and the contact list exportable. Get it in the contract.
What is reported, how often, and against what number?
A monthly PDF of impressions is not reporting. Ask for calls, forms or orders by channel, and how often you can see them.
What is the strategy revisited against, and when?
If the plan is written at the kickoff and reviewed quarterly, you are paying monthly for a document from January.
