You've probably done the napkin math on outbound. Hire a few SDRs, hand them a dialer and a list, and have them work through 80 calls a day. It looks reasonable until you add up what eight straight hours of a person dialing costs, and compare it with what the same budget could buy.
The per-minute rate on your phone bill is the number everyone looks at. Most of the money goes to everything around the call: time spent dialing numbers that ring out, hours lost to voicemail, ramp time for new hires, and pay and benefits for a team that spends 70% of its day not talking to anyone.
What a manual dialing team costs
A fully loaded SDR in the United States costs between $65,000 and $95,000 a year. That covers base salary, variable pay, benefits, and payroll taxes. In expensive markets like San Francisco or New York, it easily passes six figures. We'll call it $80,000 a year, or about $6,700 a month.
An experienced, motivated SDR makes 60 to 100 dials a day. Roughly 15% to 25% of those become live conversations. The rest go to voicemail, get screened, or ring out. That's 15 to 25 conversations on a good day. Across a team on an average day, it's closer to 12 to 18.
Over a month, that's about 300 to 400 live conversations per SDR. Say 20% of them turn into meetings, which is solid for cold outbound. You get 60 to 80 meetings per SDR per month, at $84 to $112 per meeting.
Where an SDR's day goes
Most of the expense is the dead time between calls. A typical day breaks down roughly like this:
- Dialing and waiting for pickup takes about 3 to 4 hours: listening to rings, sitting through voicemail greetings, and navigating phone trees.
- Leaving voicemails takes about 1 to 1.5 hours. Most SDR managers recommend voicemails for follow-up touchpoints. Each one takes 30 to 60 seconds.
- Logging activity in the CRM takes 45 minutes to an hour. Every call needs a disposition, notes on what was discussed, and a next step.
- Researching contacts before calling takes 30 to 45 minutes of scanning LinkedIn, reading recent news, and preparing talking points.
- Live conversations take about 1.5 to 2.5 hours. That's the only part of the day that directly generates pipeline.
So you're paying $6,700 a month for roughly two hours of conversation a day. The rest is overhead. It exists because a person can't dial, listen, log, and research at the same time.
Adding lines instead of headcount
Our dedicated lines each carry one outbound call at a time. An AI voice agent can hold conversations on those lines without breaks, CRM logging delays, or research time. It already has the context from your knowledge base and CRM data before the call starts. Contact sales for line and usage pricing.
Throughput grows with line count. These figures assume each line has enough warmed phone numbers behind it to stay within the daily cap of 50 calls per number:
- 40 lines handle up to 2,000 calls a day, or 60,000 a month. That's about what 20 to 30 SDRs dial by hand, at a fraction of the cost.
- 80 lines handle up to 4,000 calls a day, or 120,000 a month.
- 200 lines handle up to 10,000 calls a day, or 300,000 a month. That volume would take an entire floor of SDRs.
- 400 lines handle up to 20,000 calls a day, or 600,000 a month.
The cost per live conversation drops sharply because the agent skips the dead time that fills most of an SDR's day. It dials and waits for pickup. If nobody answers, it leaves the approved voicemail and moves on. It doesn't deliberate over what to say, switch CRM tabs, or take a coffee break.
The cost of 200 meetings
Say you want to book 200 meetings a month from outbound calling. If 20% of live conversations become meetings, you need about 1,000 of them. At 15 conversations per SDR per day and 22 working days a month, each SDR has about 330 conversations a month. You'd need three SDRs. That's about $20,000 a month in fully loaded compensation.
With AI agents on dedicated lines, those 1,000 conversations come from a much higher dial volume at a much lower cost per dial. Twenty lines can make 1,000 calls a day. At a 20% connection rate, that's 200 live conversations a day, so you'd reach 1,000 conversations in five days instead of a full month. Contact sales to compare the total cost, including voice usage, with your staffing budget.
Reps still own the meeting
The most valuable conversations in outbound are the discovery call, the negotiation, and the close. They take empathy, judgment, and the ability to read between the lines of what a prospect is saying. AI agents are very good at the top of the funnel: making first contact, qualifying against your criteria, answering early questions, and booking the meeting. The meeting itself, and everything after it, is where a skilled rep makes the difference.
Treat AI agents and your reps as two layers of the same funnel. The agents take volume and speed at the top. Your reps build the relationships further down. Together they work at a scale and speed neither could reach alone.
Rethinking your outbound budget
If you spend $20,000 to $40,000 a month on an SDR team, work out how much of it pays for live conversations and how much pays for overhead. You'll likely find plenty to rebalance. Moving even part of your first-touchpoint volume to AI agents frees your reps for the conversations that close revenue. It also raises the total number of conversations you have each day.
Once the first touchpoint no longer takes an $80,000-a-year employee, the cost of filling the top of your pipeline changes. You decide where the freed budget goes. If you work this out before your competitors do, you'll have an edge in any market where speed and volume matter.
