What happens to your investment when an SDR leaves?
Turnover resets the clock — and it happens more often than most hiring plans account for.
SDR turnover averages 34% annually, according to Bridge Group research. In practice, that means roughly 1 in 3 SDRs will leave within 12 months.
When an SDR leaves, you absorb:
- Re-recruiting costs: $8,000–$15,000
- Lost pipeline during the gap: typically 6–10 weeks
- A new ramp period: 3–4 months for the replacement
- Management time re-training and re-onboarding
That 34% annual turnover rate means every 3 years, you’ve effectively rebuilt your SDR team from scratch. The cost isn’t just the hire — it’s the perpetual re-start.
Pipeline continuity is the number most people overlook. A 6–10 week gap without an active SDR doesn’t just cost you recruiting fees — it costs you the opportunities that would have been worked, qualified, and handed to your AEs during that window. That gap compounds forward into the next quarter’s number.
Understanding the full picture of when to outsource your SDRs often comes down to exactly this: how much turnover drag has your current model absorbed, and what would it cost to eliminate it?
Tip: Build turnover into your hiring model from the start. If you’re planning a 4-rep SDR team and assume 34% annual turnover, budget for 1–2 replacement hires per year — including their recruiting costs and a full ramp period each. Most models don’t account for this, and most pipeline projections suffer for it.
