The Short Answer
HR outsourcing vs in-house comes down to one comparison most companies never run: the full cost of doing HR yourself against the real price of having an operator do it. In-house HR for a mid-market company runs $475 to $985 per employee per year once you count salaries, software, and compliance time. That is $40 to $82 per employee per month. Managed HR outsourcing runs $30 to $50 per employee per month, payroll plus HR support and compliance included. For a 200-person company, that is $72,000 to $120,000 a year outsourced against $95,000 to $197,000 in-house. The hr outsourcing vs in-house numbers favor outsourcing for most companies between 50 and 2,000 employees, but not all of them, and this guide shows you exactly where the line is.
Why Most Companies Get This Comparison Wrong
Most companies never actually run the hr outsourcing vs in-house numbers. They treat the hr outsourcing vs in-house decision like a gut call instead of a math problem. They get a vendor quote, look at the number, and compare it against zero. As if the HR work happening in-house today is free.
It is not free. After 15 years and 570 client engagements at Axiom Human Resource Solutions, the most common thing I see in this decision is a leadership team that knows the vendor quote to the penny and has never once totaled what their current setup costs.
This article runs both numbers. Five comparisons: the true in-house cost, the three outsourcing tiers, and the head-to-head for a 200-person company. Plus the section vendors usually skip, which is when staying in-house is the right call.
What Does In-House HR Actually Cost a Mid-Market Company?
Start with the obvious line item. An HR generalist’s salary, plus benefits on top of it.
Then add the lines nobody totals. The HRIS subscription. The payroll software. The hours your managers spend answering HR questions because one generalist cannot cover 200 people. The recruiter fee when that generalist leaves and takes every undocumented process with them. SHRM guidance on HR staffing is clear that the function is bigger than one salary line.
Run all of it and a typical mid-market company lands between $475 and $985 per employee per year. When companies finally do the hr outsourcing vs in-house math honestly, that in-house number almost always surprises them. The line-by-line breakdown is in our real HR outsourcing cost facts article.
The number that matters most is not on any invoice. It is concentration risk. In most 200-person companies, the entire HR function lives in one or two heads.
What Does HR Outsourcing Cost Compared to In-House HR?
The hr outsourcing vs in-house cost gap widens the closer you look at what each side actually includes.
Payroll only is the entry tier. Processing, filings, direct deposit. If your pay rules are simple and single-state, this plus an in-house generalist may be all you need.
Managed HR is the tier that competes head to head with an in-house department. Payroll plus HR support plus compliance monitoring, delivered by named people instead of a call center. This is where the hr outsourcing vs in-house comparison is most direct and most favorable to outsourcing.
Full HRO with UKG Ready included is the premium tier. The software, the implementation, and the full service layer in one contract. This is where healthcare, manufacturing, and construction employers with complex pay rules usually land. Our overview of HR outsourcing services for mid-market businesses covers what each tier includes in detail.
The 5-Way HR Outsourcing vs In-House Cost Comparison for a 200-Person Company
| Option | Per employee per month | 200-person annual cost | What you get | Who owns compliance |
|---|---|---|---|---|
| In-house HR | $40 to $82 equivalent | $95,000 to $197,000 | One or two generalists plus software subscriptions | You |
| Payroll only | $5 to $10 | $12,000 to $24,000 | Processing and filings, no HR support | You |
| Managed HR services | $30 to $50 | $72,000 to $120,000 | Payroll, HR support, compliance monitoring, named experts | Shared, vendor-led |
| Full HRO with UKG Ready | $50 to $75 | $120,000 to $180,000 | Complete outsourcing with software included | Vendor, with named experts |
| Hybrid (keep strategic HR, outsource admin) | Varies by scope | Between the tiers above | Your HR leader stays, payroll and compliance move out | Shared |
What Does a 200-Person Company Actually Save by Outsourcing HR?
The hr outsourcing vs in-house math is short. At $30 per employee per month, 200 employees cost $6,000 a month, which is $72,000 a year. At $50, it is $10,000 a month, which is $120,000 a year.
The in-house range for the same company is $95,000 to $197,000. So the top of the managed HR range still comes in under most in-house setups.
And the hr outsourcing vs in-house comparison is not apples to apples in the way you might expect. The in-house number usually buys one overworked generalist. The outsourced number buys a team with a payroll specialist, a compliance function, and coverage when somebody takes a vacation.
The savings argument is real. The continuity argument is bigger. Nobody resigns your outsourcing contract two weeks before open enrollment.
What Do You Give Up When You Outsource HR?
Honesty matters in the hr outsourcing vs in-house conversation. There are real trade-offs.
You lose the person an employee can walk up to at 2pm with a sensitive question. You lose someone reading the room in the building every day. For some workforces that presence is worth real money.
And with the wrong vendor, you lose much more. We documented the seven HR outsourcing risks that show up when companies pick the wrong operator: lock-in, compliance gaps, junior implementers, account manager rotation, wrong pay rules, compliance drift, and zero human accountability. Every one is avoidable. None of them avoid themselves.
When Is Keeping HR In-House the Right Call?
This is the hr outsourcing vs in-house section most vendors skip. Axiom is not the right fit for every company, and pretending otherwise would cost you money and cost us credibility.
If you are under 50 employees, you are below our sweet spot of 50 to 2,000, and a single generalist or a PEO arrangement may serve you better.
If you have a strong HR leader on a modern platform with low turnover, the hr outsourcing vs in-house math may not move enough to justify the disruption of switching. Run the numbers anyway, but do not switch for a rounding error.
If your biggest HR need is somebody physically walking a plant floor managing employee relations every day, do not replace that person. Keep them, and consider the hybrid play: outsource the payroll, compliance, and administrative load so they can do the human work. The U.S. Department of Labor compliance workload alone is a full-time job nobody hired your HR leader to do.
How Do You Decide Between HR Outsourcing and In-House HR?
The hr outsourcing vs in-house decision comes down to three questions.
Question one: what does HR actually cost you today? Total it honestly. Salary, benefits, software, manager hours, turnover. Divide by headcount. Put that number next to the tiers above.
Question two: what breaks if your HR person quits tomorrow? If the answer is payroll, compliance, and open enrollment all at once, you have a concentration risk problem, not a staffing question.
Question three: who owns compliance when a state law changes? If the answer is whoever notices, the cost of that gap will eventually show up. It just will not show up on this year’s budget.
Run the hr outsourcing vs in-house math before you decide. A 200-person company can spend $197,000 a year doing HR in-house and still not have a compliance answer at 4:45 on a Friday. The right managed HR contract costs less, and somebody picks up the phone.

Frequently Asked Questions
Is HR outsourcing cheaper than in-house HR for a 200-person company?
Usually, yes. Managed HR outsourcing for a 200-person company runs $72,000 to $120,000 per year at $30 to $50 per employee per month. The same company typically spends $95,000 to $197,000 per year on in-house HR once salary, benefits, software, and turnover are counted. The outsourced figure also buys a team rather than one generalist.
What does HR outsourcing cost per employee per month?
HR outsourcing costs $5 to $75 per employee per month depending on scope. Payroll only runs $5 to $10, managed HR services run $30 to $50, and full HRO with UKG Ready software included runs $50 to $75. Mid-market companies in healthcare, manufacturing, and construction with complex pay rules typically land in the upper two tiers.
How much does in-house HR cost per employee per year?
In-house HR costs a typical mid-market company $475 to $985 per employee per year. That total includes HR salaries and benefits, HRIS and payroll software subscriptions, the management hours that go to HR questions, and recruiting costs when HR staff turn over. As a monthly figure it is the equivalent of $40 to $82 per employee per month.
Can a company keep part of HR in-house and outsource the rest?
Yes, and for companies with a strong HR leader it is often the best structure. The common hybrid keeps strategic HR and employee relations in-house while outsourcing payroll processing, compliance monitoring, and benefits administration. Your HR leader stops doing administrative work and starts doing the human work you actually hired them for.
What happens to our current HR person if we outsource HR?
In most mid-market engagements the hr outsourcing vs in-house shift means the HR person stays and their job improves. Outsourcing removes the payroll processing, filings, and compliance tracking that consume their week. They keep employee relations, culture, hiring support, and management coaching. Companies that outsource to eliminate a strong HR person usually regret it, and we tell them so during scoping.
Is in-house HR ever cheaper than outsourcing?
Yes. A company with an experienced HR team already in seat, a modern HCM platform already configured, and low HR turnover can run in-house HR at a competitive cost. The hr outsourcing vs in-house math favors staying put when switching costs outweigh the savings. The mistake is assuming that is your situation without totaling the real in-house number first.
What is included in managed HR services at $30 to $50 per employee per month?
Managed HR services at $30 to $50 per employee per month include payroll processing and tax filings, HR support from named experts, compliance monitoring across the states where you operate, and benefits administration support. At Axiom that tier comes with dedicated contacts who know your pay rules instead of a rotating call center queue.
How do we compare an HR outsourcing quote against our in-house costs accurately?
Total your fully loaded in-house cost: HR salaries plus benefits, every HR and payroll software subscription, an honest estimate of manager hours spent on HR each month, and your average recruiting cost for HR turnover. Divide by employee count to get a per-employee monthly figure. That is the number you put next to the hr outsourcing vs in-house tiers above, then compare what each side actually includes.
