Cost per meeting is a fraction. The top of it, the monthly invoice, reads off a pricing page in ten seconds. The bottom of it, how many conversations the route produces in a month, takes a quarter of data to learn, and it decides the answer.

So this piece starts at the bottom. The numbers come from our own pipeline between 29 July and 1 October 2026: 24 sending identities, 3,352 invitations, 801 accepts and 199 first replies. Then we price that same denominator against a hire, an agency retainer and an operated agent, so you can run the arithmetic on your own figures by dinner.

## The denominator is one number: new people reached per identity per week

Everything downstream multiplies off a single quantity, and it has a hard ceiling that money leaves alone. One LinkedIn identity can approach a limited number of new people in a week, and the platform decides the limit.

Across the window we counted 70 identity-weeks with 20 or more invitations. The median week carried 40.5 invitations, the average 40.4, and the spread ran from 22 to 80. The heaviest rolling seven days any single identity produced was 80. That is the real operating band once pacing is spread through the day, which we cover in [why LinkedIn limits an account and the pacing that holds it steady](/blog/linkedin-limits-pacing/).

Take the 62 identity-weeks that have had time to mature, meaning the invitations went out before 25 September and have had a week to land. The average one looks like this:

- 40.8 invitations sent;
- 10.0 accepts;
- 1.73 first replies.

So one identity, run steadily, turns into roughly 177 invitations, 43 accepts and 7.5 first replies a month. That line is what all three routes are selling, at three different prices.

## From a first reply to a conversation worth having

Over the whole window, 3,352 invitations produced 801 accepts, which is 23.9%, and 199 first replies, which is 5.9% of invitations and 24.8% of the people who accepted. Our wider accept and reply bands sit in [the cold LinkedIn benchmarks we keep updated](/blog/cold-linkedin-benchmarks-2026/).

Of those 199 replies, 17 currently sit at a stage that means a qualified conversation or a booked call. That is 8.5% of first replies and one for every 197 invitations.

Put that against the per-identity figures. At 177 invitations a month, one steadily run identity produces about 0.9 qualified conversations a month. Call it one. One identity, one conversation a month, is the unit every route has to buy.

What arrives in those replies is worth knowing before you price anything. We keep a log of reply situations and what we sent back: 163 entries so far, of which 43 read as interested, 34 asked a question, 13 asked for a later date and 27 were a flat decline. A little over half of the inbound is warm enough to keep working, and the declines are mostly a sentence about who we picked.

## Route one: the hire

An SDR seat is quoted at on-target earnings and lands somewhere else entirely once employer load, tools, ramp and management time are added. We walked that line by line in [what an SDR actually costs in 2026, fully loaded](/blog/sdr-cost-fully-loaded/): roughly $80,000 on target in the US mid-market band, multiplied by a 1.25 to 1.4 employer burden, which lands at $100,000 to $112,000 a year, or about $8,300 to $9,300 a month before anyone opens a laptop.

Now apply the unit. A seat running one LinkedIn identity meets the same weekly ceiling every identity meets. For that $8,300 a month to reach the same cost per conversation as a $2,000 engagement, the seat has to produce about four identities' worth of output every month, which in practice means several channels running at once and a list deep enough to feed them.

Two other lines belong in the model. The first is ramp, published for this role at about three months for years, and planned at three to six by the hiring managers we talk to. The second is the ramp inside the channel itself, which runs on a different clock: across our 24 identities, the median gap from an identity being connected to its first invitation going out was 1.9 days, and the slowest was 18.9. The channel starts in days, the person starts in months, and payroll runs through all of it.

The case for the hire is real and it is about ownership: a person carries the discovery call, hears the objection in the room, and brings the market back to you in sentences. That is what the $8,300 buys. The volume ceiling is a separate purchase.

## Route two: the agency

Agency pricing comes in two shapes, and the shape decides what you are buying.

A retainer buys a team's attention for a month. The denominator stays yours to check, so the question to ask before signing is a mechanical one: how many sending identities will carry the work, whose identities are they, and what happens to the warmed domains and the connection graph when the engagement ends. One identity is roughly one conversation a month, and the retainer has to be read against that count.

Pay-per-booked-meeting moves the denominator into the contract, which makes the definition of a meeting the whole agreement. Pin down four things in writing: what counts as booked, what happens when the person fails to show, who is allowed to rebook and how often, and which titles and company sizes count toward the number. Each of those four is a legitimate place for two honest parties to have read the same sentence differently.

Both shapes can work. The arithmetic is the same arithmetic: price divided by conversations that reach your calendar, with the definitions agreed in advance.

## Route three: the agent, operated

Our own ladder starts at $199 a month for read access from your own model and runs to $2,000 a month for the operated version, where the system does the work and a person tunes it. The next steps are $5,000 and $10,000. You can see the whole shape on [the page where we break down cost per meeting](/sdr-cost/).

Run the unit against the middle step. At one identity producing about 0.9 qualified conversations a month, $2,000 a month is roughly $2,200 a conversation. Add a second identity and the same subscription covers both, so the figure falls to about $1,100. Add a third and it keeps falling. The whole economic argument for this route sits in that sentence: the subscription stays close to flat while identities and channels multiply, so what you are buying is cheap denominators.

Email is the second denominator. We price it to clients at 6 cents a message, which means 1,000 messages a month adds $60 to the invoice. Our own email channel opened on 8 September and has carried 458 sends so far, which is young enough that we quote the price and hold the reply rate until the sample earns a number.

The human part stays visible. Since 8 September our reply console has carried 669 drafts for live inboxes. Of the 170 that went out, 128 went on the timer and 41 were sent by a person who pressed the button, and 70 of the 170 were edited before leaving. So roughly three quarters of outgoing replies are routine enough to run themselves, and the remaining quarter is where a person earns their keep. The full classification we run is in [how we handle replies, with classes and an SLA](/blog/reply-handling-system/).

## What actually moves the number

Three things move cost per meeting on our own data.

**Identities.** The ceiling applies to each identity separately, so the cheapest increase in output is one more credible sender. That is why [a founder's own profile](/blog/founder-led-outbound/) carries most of the volume in a small company, and why the second and third senders usually come from inside the team.

**Reply speed.** A reply answered in twenty minutes is a different asset from one answered in two days. We hold a 48 hour ceiling and run a median far inside it.

**Who is on the list.** The 27 flat declines in our log are mostly a sentence about targeting, and each one is cheaper to read than to repeat.

Here is the arithmetic to run tomorrow on your own figures. Take your last 90 days. Count invitations or cold emails sent, count replies, count conversations that reached a calendar. Divide your total outbound spend for those 90 days by that last number. Whatever route you are on, you now have the one figure that compares across all three, in your own definitions.

## Questions buyers ask

### How much does an AI SDR cost compared to hiring an SDR?

An operated agent on our ladder is $2,000 a month, and read access from your own model starts at $199. A US SDR seat at $80,000 on target lands at $100,000 to $112,000 a year fully loaded, which is about $8,300 to $9,300 a month. The seat has to produce roughly four times the output of a single sending identity to match the operated engagement on cost per conversation.

### What is a realistic cost per meeting for LinkedIn outreach?

On our own numbers, one steadily run sending identity produces about 177 invitations, 43 accepts and 7.5 first replies a month, and roughly one qualified conversation. At $2,000 a month that is about $2,200 a conversation on one identity and about $1,100 on two, because the subscription is close to flat as identities are added.

### Should I pay an agency per meeting or on a retainer?

Both work when the definitions are written down. Per-meeting pricing moves the denominator into the contract, so agree in advance what counts as booked, what happens on a no-show, who may rebook, and which titles count. A retainer keeps the denominator visible to you, so ask how many sending identities carry the work and who keeps the warmed domains and the connection graph afterwards.

### How long before an outbound channel produces its first meeting?

The channel itself starts in days: across 24 identities our median gap from connection to first invitation was 1.9 days. Reaching a first qualified conversation takes roughly 197 invitations at our rates, which is about five weeks of one identity running at 40 invitations a week. A new hire is usually planned at three to six months of ramp on top of that.
