The real math behind why your SDR team costs more than you think

I used to build the reports that tracked this stuff.

Pipeline created, ACV closed, cost per opportunity, quota attainment by rep, I lived in these spreadsheets as an SDR manager.

So when someone tells me "SDRs are cheaper than an agency or a system," I have a lot of thoughts.

Let's actually do the math, the way I used to do it for leadership reviews.

What an SDR Actually Costs You

Say you hire one SDR at a $55K base with OTE around $75K. Sounds reasonable, right?

Now add:

• Benefits & payroll tax: usually adds 20-30% on top

• Tools: ZoomInfo, Sales Nav, an engagement platform like Outreach, intent data like 6Sense, easily $500-$1,000/month per seat when you divide out licensing

• Management overhead: someone (me, in my case) spending real hours coaching, reviewing calls, building playbooks, running pipeline reviews

• Ramp time: 60-90 days of reduced output while they learn the role

• Turnover: SDR roles churn fast; you're rarely getting 3+ years out of one hire before you're ramping someone new

By the time you add it all up, a single SDR often costs $90K-$120K+ in year one when you're honest about the full picture.

And that's before you ask whether they're actually any good.

What You're Actually Buying

Here's what really got me thinking about this differently.

When I introduced automated sequencing to my team of 10, we didn't get 10x better SDRs.

We got the same SDRs producing dramatically more volume because the manual, repetitive parts of the job got handled automatically.

That's the part that made me realize: you're not really paying for a person.

You're paying for output. Reach, conversations, qualified opportunities.

The person is just the current mechanism for producing that output, and it's a fairly expensive, inconsistent mechanism.

The Agency Retainer Trap

If you've looked at SDR agency retainers instead, the math doesn't actually improve much.

You're usually paying $6K-$10K/month, locked into a contract, with a rotating cast of reps who don't know your business as deeply as someone internal would (or sometimes at all).

You're renting attention, not owning an asset.

When the retainer ends, you have nothing left.

No system, no data, no infrastructure.

Just a few months of activity in a CRM.

What I'd Actually Recommend Now

Having sat in the SDR chair, the manager chair, and now the "I build the systems" chair, here's my honest take: the future isn't more headcount and it's not another retainer.

It's owning a system that does the repetitive 80% of outbound (research, targeting, outreach, qualification) and paying humans to do the 20% that actually requires a human: closing.

I priced what I build around that idea.

One-time setup, then you either run it yourself for free or pay $200 only when it produces an actual qualified conversation.

No base salary.

No ramp time.

No agency retainer.

Just output, priced like output should be.
