What is the fully loaded cost of an in-house SDR in 2026?

Bridge Group benchmarks put fully loaded in-house SDR cost at $98,000 to $173,000 per year including base, variable, benefits, tooling, manager overhead, and ramp. Midpoint sits around $140,000, with cost per held meeting at $900 to $1,400.

How much do SDR agencies like Belkins, Martal, and CIENCE cost per month?

Belkins runs $3,000 to $15,000 per month, Martal $7,500 to $12,000, and CIENCE $5,000 to $10,000. Setup fees of $1,000 to $15,000 are common. Year one cost per held meeting lands at $3,000 to $5,000 for mid market motions.

When does a fractional SDR make more sense than an agency?

Fractional fits when the ICP is locked, one or two closers can absorb meetings, and budget sits at $50,000 to $100,000 per year. A fractional SDR gives one dedicated operator at $4,000 to $8,000 per month with short notice exits, which an agency model rarely matches.

Can a small team mix in-house, agency, and fractional SDRs?

Yes, and the blended approach is common at growth stage. Agency or fractional capacity covers volume and ICP testing while in-house handles named accounts. The key is shared tooling and a single source of truth so meeting credit and pipeline coverage stay clean across all three sources.

In-House SDR vs Agency vs Fractional: Which Wins in 2026

The choice between in-house, agency, and fractional SDR staffing in 2026 is a decision about playbook maturity, deal size, and risk tolerance, not just cost. This article compares the three models on fully loaded cost, ramp time, and control, and walks through the conditions under which each model wins.

How the three models compare on cost

In-house SDRs run $98,000 to $173,000 fully loaded per year. Agencies run $3,000 to $15,000 per month with setup fees. Fractional SDRs run $4,000 to $8,000 per month. Cost per held meeting lands lower in-house once ramped, but agency and fractional win on time to first meeting.

When each model wins

In-house wins for locked ICP, named accounts, and ACV above $30,000. Agencies win for volume testing and net new market entry where playbook is still in flux. Fractional wins for small teams with limited closer capacity and a locked ICP that needs one focused operator.

Common pitfalls across all three

The most common failure across all three models is staffing for budget rather than stage. The second is buying agency volume without enough closer capacity to absorb meetings. The third is treating fractional SDRs like full time hires and starving them of context.
