In-House vs. Outsourced Call Center: A Real Cost Comparison
Salary, benefits, turnover, training, management overhead — the true cost of an in-house agent is rarely what it looks like on paper.
The paycheck is the tip
Why the job posting lies to you.
When owners weigh hiring another CSR against outsourcing their phones, the comparison usually starts — and ends — with an hourly wage. "I can get someone for $20 an hour. Why would I pay a service?" The wage is real, but it is the smallest surprise in the budget.
Every in-house agent carries payroll taxes and benefits, management time, recruiting and ramp-up costs each time someone quits, phones and software, and training. Then there is the cost nobody puts on a spreadsheet: the hours your phones are not covered at all.
| Cost category | Annual amount |
|---|---|
| Base wage ($20/hr × 2,080 hrs) | $41,600 |
| Payroll taxes & benefits | $16,582 |
| Supervision & management time | $9,360 |
| Turnover (recruiting + ramp) | $2,485 |
| Phone, CRM & software seat | $1,800 |
| Ongoing training | $800 |
| Total annual cost | $72,627 (≈ $6,052/month) |
Assumptions: $20/hr × 2,080 hrs. Benefits at 28.5% of total compensation (BLS). Management: 3 hrs/week of a $60/hr manager. Turnover: 35% annual rate × $7,100 per departure. Replace with your numbers.
The cost you can't see on payroll
One agent covers about half your business hours.
A full-time employee is paid for 2,080 hours a year. Take out ten days of PTO and eight holidays and you get about 1,936 working hours — before lunch breaks, sick days, or time spent on another line. If your phones need answering 7 am to 7 pm, Monday through Saturday, that is 3,744 hours a year. One person, no matter how good, physically cannot be there for half of them.
| Metric | Value |
|---|---|
| Working hours from one FTE after PTO and holidays | 1,936 |
| Business hours a year at 72 hrs/week | 3,744 |
| Share of business hours one person can cover — at best | 52% |

When in-house still makes sense
The model is not a verdict — it is a tool.
Keep it in-house when you have a long-tenured CSR with deep customer relationships, the role blends phones with dispatch and billing, or call volume is low and steady with few evening or weekend calls.
Outsource or go hybrid when you are losing calls to spikes, lunch, after-hours or turnover; when you or your office manager are spending hours a week managing the phones; or when you want call capacity to grow with marketing — without another hiring cycle.
