The Number: 34 Percent Annual Turnover
dialfyne.com's SDR statistics, attributing the figure to Bridge Group, put annual SDR turnover at roughly 34 percent, described as about three times the churn rate of other industries. Median tenure lands at 14 to 18 months. Both figures are directional, aggregated benchmark data rather than a single audited dataset, but they are consistent with how the SDR seat is widely discussed across the outbound category: an entry point role that a lot of people pass through rather than settle into.
Why the Tenure Number Matters More Than It Looks
14 to 18 months sounds like a reasonable run for an entry-level role, until you subtract the ramp period. Applying the 5.7-month ramp benchmark from the companion guide, a rep with 14 to 18 months of total tenure is only spending roughly 8 to 12 months of that window producing at something close to full capacity. The rest is ramp time on one end and, in many cases, a slower final stretch before they leave on the other.
The Cost Cycle This Creates
A fully loaded SDR runs $98,000 to $173,000 a year, per the industry-estimate range attributed to Bridge Group's 2025 report. If that cost buys roughly 8 to 12 productive months before a 34 percent annual churn rate takes the rep off the team, a company isn't paying that cost once, it's very likely paying some version of it again within two to three years per seat: a new recruiting cycle, a new ramp period, and a new stretch of below-capacity output while the replacement gets up to speed.
A Plausible Reason Turnover Runs This High
Low quota attainment is a reasonable contributor, though the two figures come from different measures and shouldn't be read as directly causal. dialfyne.com's statistics, citing RepVue's 2025 data, put SDR quota attainment in software specifically at 41.2 percent, the lowest of any segment measured. A role where most people are missing quota most of the time is a harder role to stay motivated in, which is a sourced, plausible piece of the turnover picture even without a direct causal study connecting the two numbers.
What Turnover Means for a Buy vs. Build Decision
Every time an SDR leaves, the hiring cost, the ramp-time cost, and the productivity gap all reset. A pay-per-meeting model doesn't carry that reset risk in the same way: VA Horizon bills $350 to $600 per held, double-confirmed SaaS demo with a $300 one-time setup, and that setup fee is paid once, not every time a rep turns over. The system behind the meetings doesn't quit.
How to Use This Number If You're Building a Team
If you're planning to hire, build the 34 percent churn assumption into your budget rather than treating a hire as a one-time cost. Plan for a replacement cycle roughly every two to three years per seat, and price the ramp-time cost of that replacement in alongside the fully loaded salary. If that math is getting uncomfortable before you've hired a single rep, it's worth running the comparison against a per-meeting rate before you commit to headcount.
What this means for you
- SDR annual turnover runs roughly 34 percent, about three times other industries, with median tenure of 14 to 18 months, attributed to Bridge Group via dialfyne.com.
- Subtracting a 5.7-month ramp from 14 to 18 months of tenure leaves roughly 8 to 12 productive months before a typical rep leaves.
- A pay-per-meeting model pays its one-time setup once. Headcount turnover means the fully loaded cost and ramp cost are very likely paid again within two to three years, per seat.
