Outsource WordPress Development or Hire In-House? The Math

An agency should outsource WordPress development when build work arrives in bursts, and hire in-house only when there is enough steady work to fill a developer’s week, every week. For most small and mid-sized agencies the numbers favor outsourcing by a wide margin. The reasons to hire anyway are real, but they are rarely about cost.

This guide is for agency owners and delivery leads who sell websites and have to decide who builds them. It prices both routes with public data and published rates, shows the hours at which each model wins, and lists what should stay inside your agency whichever way you go.

Four ways an agency can staff WordPress builds

The choice is wider than employee or contractor. Each option below trades cost against control and availability.

Option	You pay	Strong point	Weak point
In-house developer	Salary and benefits every month, busy or quiet	Always available, knows your clients and standards	Fixed cost, one person’s skills, gone when they leave
Freelancer	By the hour or project	Flexible and often quick to start	One person, so holidays, illness and other clients affect you
White-label partner, per project	A fixed price per page, project or hour	Cost follows your sales, and a team covers absences	Needs a clear brief, and is not at your desk
Dedicated developer through a partner	A flat monthly fee	Works as part of your team without the hiring	You must supply enough work and direction to fill the month

We sell the last two, so read our numbers with that in mind. Our white-label WordPress development for agencies is priced publicly, which lets you check every figure in this article.

What an in-house WordPress developer really costs

Salary is the part you see. The US Bureau of Labor Statistics reports that the median wage for web developers was $92,650 a year in May 2025. Half earn more and half earn less, and pay differs by city and seniority.

Benefits and payroll costs sit on top. The same agency’s Employer Costs for Employee Compensation release shows that in June 2026 wages made up 70.0% of what private employers paid per worker, with benefits the other 30.0%. That share is an average across private industry, not a figure for web developers alone, so use it as a planning ratio.

Step	Math	Result
Median wage (BLS, May 2025)	Reported figure	$92,650 a year
Add benefits at the average private-industry share	$92,650 divided by 0.70	about $132,400 a year
Per month	Divided by 12	about $11,030
Per paid hour	Divided by 2,080 hours	about $64
Per hour that reaches client work	Divided by 1,500 hours, our assumption	about $88

The last row matters most. Nobody spends all 2,080 paid hours on client builds. Holidays, leave, meetings, training and the gaps between projects take a share. We used 1,500 hours as a round assumption; put in your own number. The fewer hours you can fill, the more each one costs.

The table also leaves out recruiting, equipment, software and the weeks a new hire needs before they are useful. If you are weighing the hourly market instead, our guide to what a WordPress developer costs covers freelance and agency rates.

Sources: BLS Occupational Outlook Handbook, Web Developers and Digital Designers, and BLS Employer Costs for Employee Compensation, June 2026 (released September 9, 2026). Both checked on November 12, 2026. UK and EU employers should use their own national wage and employer-cost figures.

What it costs to outsource WordPress development

Partners charge in three ways, and many offer all three. These are our own white-label rates, shown with the conditions attached. Other partners, especially those based in the US or UK, charge more, so ask for a rate card and run the same math.

Model	Our rate	Conditions	Fits
Hourly	$20 an hour	Estimate agreed before work starts, time report with each invoice	Fixes, changes and overflow tasks
Design to WordPress	$59 per page	Built from your design files in Elementor or Gutenberg	Sites your team has already designed
Page design	$49 per page	Desktop and mobile layouts, delivered under your brand	Agencies without a designer free
Dedicated mid-level developer	from $1,290 a month	Full-time for your agency, 30 days’ notice to cancel	A steady flow of WordPress and front-end work
Dedicated senior developer	from $1,890 a month	Full-time for your agency, 30 days’ notice to cancel	Custom plugins, integrations and code review

Every model includes a signed NDA, no Attors branding anywhere, and changes tested on a staging copy. The full list is on our pricing page. A year of a dedicated mid-level developer comes to $15,480 at the starting rate, which is under 12% of the in-house figure above.

That gap exists because our team is based in Gujrat, Pakistan, where costs are lower, and works remotely with agencies in the US, UK and Europe. Our comparison of offshore and onshore web development covers the trade-offs that come with it.

The break-even hours for each model

Two calculations settle most of the decision. Both use your monthly hours of build work, so pull that number from your last six months of projects before you read on.

• Hourly or dedicated. Divide the monthly fee by the hourly rate. At our rates, $1,290 divided by $20 is about 65 hours. Below 65 hours of work a month, buy hours. Above it, a dedicated mid-level developer costs less. For a senior developer the line is about 95 hours.
• Outsourced or in-house. Divide the in-house monthly cost by the partner’s hourly rate. With the BLS-based figure of about $11,030 a month and a partner charging, say, about $60 an hour, the line is about 184 hours a month, which is more than one full-time person works. At $20 an hour it is about 550 hours, more than three people.

Put another way, under the assumptions above an in-house developer costs about $88 per client hour. Any partner charging less than that per hour is cheaper for the same output, before you count the hours you spend briefing and checking.

One project shows the scale. A ten-page site built from your designs costs $590 at $59 per page. The same $590 buys under seven hours of an in-house developer’s client time at about $88 an hour. If your agency sells that site for, say, a fee of about $3,500, the build is about 17% of the price and the rest pays for strategy, design, project management and profit.

What outsourcing costs besides the invoice

The rate card is not the whole cost. Outsourcing moves work onto whoever manages the partner, and agencies that ignore this are the ones that say it failed.

• Briefing time. An in-house developer absorbs context in the hallway. A partner knows only what you write down. Expect to produce a proper brief: designs, page list, plugins allowed, hosting details and what done means.
• Review time. Someone on your side must check each delivery against the brief before the client sees it.
• Time zones. A partner several hours ahead can turn work around overnight, but a question asked late in your day may wait until morning. Agree on overlap hours and a response time.
• Switching cost. The first project with any partner is slower than the fifth. Judge the model after three projects, not one.

From our projects: Several agency clients have worked with us on project after project for five years or more. On dedicated plans the developer joins the agency’s Slack and project tools, sends daily updates and a weekly report, and works in the agency’s time zone overlap, so the agency’s project manager directs the work the same way they would direct an employee.

When hiring in-house is the better call

Cost is one input. In these situations we would tell an agency to hire, even though we sell the alternative.

• Engineering is your product. If clients choose you for deep WordPress engineering, such as complex plugins or large platforms, that skill should live inside the company.
• Contracts or regulation require it. Some clients, especially in government, healthcare and finance, forbid subcontractors or require background checks and data to stay in one country.
• One long-running platform. A single large site that needs daily attention for years rewards a person who knows every corner of it.
• You need someone in the room. Workshops, on-site discovery and same-minute pairing with designers are hard to do remotely.
• The work is steady and the budget is there. If you can fill 1,500 or more client hours a year and the salary does not strain cash flow in a slow quarter, an employee is a reasonable choice.

Many agencies end up with both: one in-house lead who owns standards and reviews, and a partner who supplies the build hours.

Keep these in-house even when you outsource the build

Outsourcing development does not mean outsourcing the agency. The parts clients pay a premium for should stay with you.

• The client relationship. All client contact goes through your team. A white-label partner should never email your client.
• Strategy and scope. What gets built, in what order, and what it costs the client.
• Design direction. Even if page layouts are produced outside, the brand decisions are yours.
• Final quality check. Your name is on the site, so your team signs it off.
• Account ownership. Hosting, domains, plugin licenses and repositories sit in your accounts or the client’s, never the partner’s.

Risks of outsourcing and the terms that control them

Each common fear has a contract term or a working habit that answers it. Get these in writing before the first project.

Risk	What to put in place
The partner approaches your client	NDA and non-solicitation clause, and no partner branding in code, emails or reports
Unclear code ownership	A clause that all work transfers to you on final payment
Quality below your standard	A written definition of done, a staging site for review, and a paid trial project first
Missed deadlines	Milestones with dates, and progress updates on a schedule you set
Access and security	Individual logins, not shared passwords, removed when the project ends
Worker classification	For a US freelancer who works mainly for you, check the IRS guidance linked below

On the last row: the IRS explains how to tell an independent contractor from an employee using behavioral, financial and relationship tests. A freelancer who works set hours only for you can look like an employee under those tests. Contracting with a company is simpler in this respect. This is practical guidance, not legal advice, so check with your adviser.

How to test outsourcing on one project

You do not have to decide the whole model at once. One real project tells you more than any sales call.

1. Pick a small, real job. A five to ten page site or a defined set of fixes, with a client deadline that has some slack.
2. Write the brief you wish you always had. Designs, page list, plugin rules, hosting access and acceptance criteria.
3. Agree on a fixed price and dates before work starts, and sign the NDA.
4. Review on staging. Check the build against the brief on phone, tablet and desktop, and log changes in one list.
5. Count your own hours. Add the time you spent briefing and reviewing to the invoice. That total is the true cost.
6. Compare. Set that total against what the same job would have cost at your in-house cost per client hour.

If the result is good, repeat it twice before moving to a monthly arrangement. Once builds are settled, ongoing care is the next thing agencies hand over; our white-label WordPress maintenance starts at $25 per site a month.
