In short: For 600 calls a month averaging two and a half minutes, an outsourced call center charging per minute costs roughly €750 to €1,800, a large German answering service about €2,700 net according to its price list, and a full-time employee about €2,930. An AI voice agent costs €450 for the same minutes with EchoCall and answers around the clock. Humans still win with complaints, advice that needs judgement and conversations built on trust. The best setup is often both: AI for the routine, people for the rest.
We rewrote this article in October 2026. The previous version quoted staff turnover above 30 percent, costs of €4.50 to €12 per call and 1,000 simultaneous conversations. We had no source for any of these figures. They are gone. Every number in this version is either sourced or marked as an assumption.
The prices below are from Germany and in euros. The method works anywhere: put in your local prices.
Four ways to staff the phone
| Option | How it is billed | Typical prices | Availability |
|---|---|---|---|
| In-house team | salary plus employer contributions, whether the phone rings or not | German call center agent median €2,420 gross, about €2,930 with employer contributions [1][2] | the team's working hours |
| Answering service | monthly fee plus a price per call and per minute | Example ebuero: from €59.90 a month, from €1.04 per call, from €1.04 per started minute, net [3] | core hours, often Mon to Fri 7 am to 7 pm |
| Outsourced call center | per minute, per contact or per agent hour | €0.50 to €1.20 per minute, €2 to €8 per contact, €25 to €45 per hour [4] | by contract |
| AI voice agent | plan with minutes of conversation | EchoCall: from €75 for 250 to €1,500 for 5,000 minutes, about €0.30 a minute [5] | around the clock |
The outsourcing prices come from a review of public price information from German-language providers, published by the outsourcing company yoummday in October 2026. [4] They are market ranges, not quotes. A real contract depends on volume, languages, service hours and minimum term.
A worked example you can redo
You calculate call center costs from three numbers: calls per month, average call length, price per unit. The unit is the minute, the call or the hour. With hourly rates, what counts is paid time, not talk time, even when nobody calls.
An example with assumptions: 600 calls a month, 2.5 minutes on average, so 1,500 minutes of conversation.
| Option | Calculation | Cost per month |
|---|---|---|
| AI voice agent, EchoCall Professional | plan with 1,500 minutes | €450 |
| Outsourcing, per-minute price | 1,500 minutes × €0.50 to €1.20 | €750 to €1,800 |
| Outsourcing, per-contact price | 600 contacts × €2 to €8 | €1,200 to €4,800 |
| Answering service, ebuero Profi | €179.90 + 600 calls × €1.04 + 1,800 started minutes × €1.04 | about €2,676 net |
| Full-time employee | €2,420 gross plus about 21 % employer contributions | about €2,930 |
On the answering service: at 2.5 minutes, each call is billed as three started minutes. The price list shows call answering per call and call handling per started minute as separate service fees. [3] Other answering services charge differently, some with bundles. Redo the sum with your provider's price list.
On the employee: 1,500 minutes of conversation are 25 hours of pure talk time. One full-time person can handle that, but only during working hours, not in the evening, not on holiday and not on the third simultaneous call. Workspace, software, team lead and training are not yet in the €2,930. How we get to about €0.35 per working minute is in our AI voice agent statistics.
What no per-minute price shows
Availability. An answering service works core hours, outside them you pay surcharges or voicemail takes over. An in-house team works its shift. An AI agent answers at 10 pm and on Sundays at no extra charge.
Peaks. Monday morning, after a campaign, during an outage: a person handles one call at a time and the rest wait in the queue. An AI agent takes several calls at once.
Knowledge. Your own team knows your business best. An answering service works from your notes and usually takes a message. An AI agent answers from a knowledge base you maintain once. When opening hours or prices change, you change them in one place.
Control. With an AI agent, every conversation is in the dashboard as a transcript and summary. You see what people asked and where the agent got stuck. With an external call center you usually see reports.
Data protection. Call center or AI, under EU law you need a data processing agreement under Article 28 GDPR. With call centers abroad, international data transfers come on top. EchoCall processes data on servers in Frankfurt and Karlsruhe, Germany. The data processing agreement and subprocessors are on the GDPR page.
Where humans win
An honest comparison has this side too:
- Complaints and escalations. An angry customer wants someone to take responsibility. An AI agent cannot do that.
- Advice that needs judgement. Goodwill gestures, special terms, cases that are in no knowledge base.
- Sales built on relationships. A key account conversation is not a job for a machine.
- Delicate conversations. Cancellations, bereavements, medical or financial hardship.
- Undocumented processes. Where nobody has written down how a request is solved, an AI agent cannot solve it either.
Gartner expects agentic AI to resolve 80 percent of common customer service issues without humans by 2029. [6] That is a forecast, not a measurement. And it talks about common issues. The rest stays with people.
The model that usually pays off: AI first, people behind it
According to Gartner, staff account for up to 95 percent of contact center costs. [7] The savings therefore do not come from replacing people with AI, but from people only handling the conversations that need them.
- The AI agent answers every call. It resolves routine requests itself: appointments, opening hours, status, simple questions.
- It recognises when a person is needed. For complaints, special cases or when the caller asks, it transfers to a number on your team.
- Outside team hours it takes a callback request. With name, number and request, so nobody has to explain twice.
- The team works through the list. With fewer interruptions, because routine calls no longer ring through.
How to calculate the mix: minutes the agent handles times €0.30, plus staff costs for the conversations that remain. You know your share of routine requests best. Count them for a week.
If you run a call center yourself
For call centers and BPO providers, an AI agent is not a replacement but an additional product. You can put it in front of your agents as the first point of contact or resell it to your clients under your own brand. How that works as a white-label solution with billing per client is in our partner program and on our page for call centers and customer service.

Six questions to decide
- How many calls do you get a month, and how long are they? Without this number every comparison is a guess.
- How many of them are routine? Appointments, status, opening hours, standard questions. The higher the share, the more an AI agent takes over.
- When do your customers call? If a real share calls in the evening or at weekends, availability matters more than the per-minute price.
- How much does volume fluctuate? Strong peaks argue against a pure staffing solution.
- Which languages do you need? Test your most important languages with real calls, for people and machines alike.
- What happens when it gets difficult? Decide who takes over before you switch.
Frequently asked questions about call center costs
How much does a call center cost per minute?
According to a review of public prices, outsourced call centers in Germany charge €0.50 to €1.20 per minute of conversation, €2 to €8 per contact or €25 to €45 per agent hour. Real quotes depend on volume, service hours and contract term.
How much does an answering service cost per call?
It depends on the provider. A well-known German answering service charges from €1.04 per call plus from €1.04 per started minute of conversation, net, plus a monthly fee, according to its price list. A 2.5-minute call there costs about €4.
How do I calculate call center costs?
Multiply calls per month by average length and the per-minute price. With per-contact pricing, multiply calls by the price per contact. With hourly rates, count paid hours, not talk time. Add monthly fees, out-of-hours surcharges and setup costs.
Is an AI voice agent cheaper than a call center?
Per minute usually yes: with EchoCall a minute of conversation costs about €0.30, with no setup fee and around the clock. Overall it is cheaper where many calls are routine. For complaints and advice you still need people.
Can the AI agent hand over to a person?
Yes. The agent transfers calls to a number on your team when a person is needed or the caller asks for one. Outside the hours your team is available, it takes a callback request with the details instead.
When is a traditional call center the better choice?
When most conversations need judgement, negotiation or empathy, when processes are not documented, or when a sales team lives from personal contact. An AI agent adds little there.
Is an AI voice agent different from a call center under data protection law?
Both process data on your behalf and need a data processing agreement under Article 28 GDPR. With an AI agent, the AI disclosure under Article 50 of the EU AI Act applies since 2 August 2026. [8] With call centers abroad, check international data transfers.
