The short answer
For most mid-size companies, an agency costs less than a full-time social media hire and delivers more skill per dollar. A salaried social media manager costs roughly $108,000 a year once benefits are included. A typical agency retainer runs about $61,000 a year.
That gap matters most to the people who don't own the business but do own the budget. General managers, property managers, regional marketing directors and branch leaders all have the same job in Q4: build a 2027 plan that ownership, a board or a management company will approve.
This guide breaks down the real cost of each option, when each one makes sense, and how to present the choice to the people who sign off.
What an in-house social media manager really costs
The salary is only about two thirds of the bill. The average US social media manager earns about $74,000 in base pay, according to Sprout Social, citing Built In data from 2026. Federal data shows wages make up just 68.5% of what employers spend on full-time private industry workers. Benefits, paid leave and payroll taxes cover the other 31.5%
Apply that ratio to a $74,000 salary and the fully loaded cost is about $108,000 a year, or $9,000 a month. Then add the costs that rarely make it into the job request:
Tools. Scheduling, design, analytics and stock media subscriptions.
Recruiting and ramp time. Weeks of job posts and interviews, then months before a new hire knows your audience and brand.
Coverage gaps. Vacation, sick days and turnover leave the accounts quiet, and posting consistency is what the algorithms reward.
One skill set. One person rarely writes strong copy, shoots and edits video, runs paid ads and reads analytics equally well.
None of this makes an in-house hire a bad choice. It means the comparison should start at $108,000, not $74,000.
What a social media agency costs
The average social media agency engagement runs about $5,100 a month, according to Clutch's April 2026 pricing guide, as reported by PostPlanify. Clutch also puts the average engagement length at 12 months. That works out to roughly $61,000 a year.
Most mid-size companies land between $2,500 and $7,000 a month, depending on scope. A retainer in that range usually covers:
A quarterly strategy built from your own performance data
Content planning, copywriting and design across two to four platforms
Photo and short-form video production
Community management: replying to comments, messages and reviews
Paid social management (ad spend is billed separately)
A monthly report that explains what worked and what changes next
The biggest difference is depth. A retainer buys a team, not a person: a strategist, a content creator, a designer and an ads specialist, without four salaries.
Which option fits your company
In-house makes sense when social media is a full-time, real-time job: daily events, breaking news, or a brand large enough to keep a team busy. An agency makes sense when you need professional results but don't have a marketing department to manage them.
Here is how that plays out in the industries where the budget holder usually isn't the owner:
Hotels and resorts. Third-party management companies often run lean property teams. A GM is juggling occupancy, staffing and guest reviews. An agency keeps the property's feed, the restaurant and bar, and event promotion moving without adding a salary line to the P&L.
Apartment communities. Lease-ups and renovations need a burst of content, then steady resident engagement. A community manager's time is better spent on tours and renewals than on editing Reels.
Shopping centers and mixed-use properties. Leasing, tenant promotions and community events all compete for the same feed. An agency can run a calendar that serves shoppers and prospective tenants at once.
Community banks and credit unions. Compliance review, trust and local reputation matter more than trends. An experienced partner builds content around deposit and loan goals, employee stories and community impact, with a review step built in.
Senior living communities. Families research for months before they call. Consistent, warm storytelling about daily life and staff builds the trust that turns into tours.
If your company has two or more of these signs, an agency is likely the better fit: no dedicated marketing team, a budget that must be justified to someone else, social accounts that go quiet for weeks, or results that are hard to explain in a monthly report.
How to justify the spend to ownership
Owners, boards and management companies approve budgets tied to business results, not follower counts. Use these four steps to build the case for 2027:
Start with the goal they already care about. Occupancy, leases signed, event bookings, new deposits or tours booked. Name one number social media will support.
Show the full cost comparison. Put the $108,000 in-house figure next to the agency retainer. Decision makers respond to a clear side-by-side.
Define what success looks like in 90 days. Pick two or three measures, such as website clicks from social, direct messages that become inquiries, or review response time.
Ask for a reporting promise. A monthly one-page summary in plain English: what ran, what worked, what changes next. That report is what keeps the budget approved next year.
The strongest pitch is a small, measurable start. A 90-day trial with clear goals is easier to approve than a vague annual commitment.
Frequently asked questions
Is it cheaper to hire a social media manager or an agency? For most mid-size companies, an agency is cheaper. A full-time social media manager costs about $108,000 a year with benefits, while the average agency retainer is about $61,000 a year.
How much does a social media manager cost a company in total? About $108,000 a year. Base pay averages $74,000, and benefits and payroll taxes add roughly 31.5% to total employer cost, based on 2026 federal labor data.
How much does a social media agency cost per month? The average engagement is about $5,100 a month. Most mid-size companies pay between $2,500 and $7,000, depending on platforms, content volume and whether paid ads are included.
Should a hotel or apartment community outsource social media? Usually, yes. Property teams are lean, and their time is better spent on guests, residents and leasing. An agency keeps content consistent and reports results to the management company.
What should a social media agency report every month? A plain-English summary of what was posted, what drove clicks, inquiries or bookings, and what will change next month. Avoid reports that only list likes and followers.
How long until social media results show up? Most companies see engagement improve within 60 to 90 days of a consistent strategy. Leads and bookings tend to follow as the right audience grows.
