In-house SDR vs. outbound agency: the real cost
The short answer
A fully loaded in-house SDR costs roughly $95K–$210K per year — about 2–3× base salary once you add benefits, tools, management and ramp — and takes 3–4 months to reach full productivity. Most of that money is spent before a single qualified meeting. A flat-fee outbound agency removes the overhead, ramp and hiring risk, and goes live in weeks.
Hiring an SDR looks like a salary line. It isn't. The base pay is the smallest part of what an in-house sales-development hire actually costs you in year one.
The "fully loaded" cost most budgets miss
Base salary is just the start. Fully loaded cost adds employer taxes and benefits, software (data, sequencing, dialer, CRM seats), management time, and the ramp period where you pay full cost for partial output. The published estimates cluster tightly:
| Source | Fully loaded SDR cost (year one) |
|---|---|
| SalesHive | $110K–$210K / yr (2–3× base) |
| Charlie AI | $110K–$150K / yr (outliers $175K+) |
| Launch Leads | $95K–$128K before a single qualified opportunity |
| Vendisys (base only) | $55K–$70K base, before loading |
Ramp and turnover: the hidden multipliers
Two factors quietly inflate the real number:
- Ramp: roughly 3–4 months to full productivity. You pay 100% of cost for a fraction of the output during that window.
- Turnover: SDR churn is notoriously high — SalesHive cites around 35%. When a rep leaves, you reset the ramp clock and re-pay the hiring cost.
So the honest year-one question isn't "what's the salary?" — it's "how much will I spend before this seat reliably produces meetings, and what happens if they leave at month nine?"
How a flat-fee agency compares
A done-for-you outbound agency restructures the cost entirely:
| In-house SDR | Done-for-you agency | |
|---|---|---|
| Year-one cost | $95K–$210K fully loaded | Flat monthly fee, no loading |
| Time to live | 3–4 months ramp | Live in ~2 weeks |
| Tools & data | You buy and manage | Included |
| Hiring & turnover risk | Yours (~35% churn) | None |
| Deliverability setup | You build it | Built in |
For reference, Ripe Leads runs on a flat €2,850/month retainer (€3,750 the first month for setup) with no tool or data fees stacked on top — a fraction of a fully loaded SDR, live in weeks rather than months.
The honest trade-off
An agency isn't automatically the right answer for everyone. A flat-fee model optimizes for quality conversations with the right buyers, not raw meeting volume — so if your only metric is "most meetings booked, cheapest," a pay-per-meeting vendor will quote a different shape. But pay-per-meeting incentives often produce low-quality calls. The flat-fee question is simpler: do you want a predictable cost and a team that protects your reputation, without carrying the hiring risk yourself?
