SDR turnover: What it actually costs (and how to stop it)
The average SDR leaves after 14 months.
For most orgs, that’s barely past full ramp. You finally have a productive rep, and they’re gone.
20% leave in the first 90 days. Before closing a single deal. Before you’ve recovered a dollar of what you spent hiring them.
Most teams call this the cost of doing business.
It’s not.
What turnover actually costs
Replacing one SDR runs $115,000 to $195,000.
Recruiting fees. Vacancy time. Lost pipeline. Starting the ramp clock over. That’s before the soft costs: manager hours diverted from development to backfilling, institutional knowledge walking out the door, team momentum taking a hit every time someone quits.
A team of 10 SDRs with 30% annual turnover isn’t a retention problem. It’s a revenue leak.
Do the math: 3 departures × $155,000 average = $465,000. Add quota miss from vacancy months. Add deals fumbled during transition. Most VPs don’t put a number on it. When they do, the conversation changes fast.
Why reps leave in the first 90 days
It’s not the money.
Two real reasons SDRs leave early: they feel set up to fail, and they can’t see a path forward.
‘Set up to fail’ sounds vague. It’s not. It means ramping on real prospects before you’re ready. Blowing calls you weren’t prepared for. Getting told what you did wrong with no safe place to practice doing it right.
When the first 90 days is a string of humiliating live calls, reps look for an exit. The exit interview says ‘better opportunity.’ The real reason is onboarding left them exposed.
Why reps leave at 12–18 months
This one’s different.
By month 12, a rep either has momentum or they’ve plateaued. The ones who go flat often don’t know why. Their manager usually doesn’t either. The signal wasn’t clean enough to catch early.
Most of these reps were coachable. They just never got the right feedback at the right time. They stalled, felt stuck, and reset somewhere else.
The orgs that catch this early have something most don’t: visibility into rep skill development over time. A rep trending toward a month-14 exit gets an intervention at month 8. Trajectory changes.
What changes when onboarding includes real practice
Fero Logistics built structured AI roleplay into their onboarding.
Reps practice before they touch live prospects. Every simulated call gets scored. Reps walk into coaching sessions already knowing what to work on, so managers aren’t starting from scratch.
Result: 40% faster ramp, 10–15 hours saved weekly in coaching, and a signal Fero didn’t expect. They now use Chambr as a hiring filter. A candidate who takes feedback, adjusts, and improves in a practice environment is more likely to last in the field.
Better signal than any interview.
Tristan MacLean put it directly: ‘Chambr let our new hires build real confidence before they ever picked up the phone on a real call. The difference was visible from week one.‘
Retention is a practice problem
Reps who feel like they’re getting better don’t leave.
That’s the whole thing.
Operationally, it’s hard. Most orgs have no consistent way to show reps their own progress. Manager calendars don’t allow regular feedback loops. Monthly reviews are too sparse. Reps feel adrift between check-ins and start looking around.
When practice is built into the rhythm (daily or weekly simulated convos, scored feedback, visible week-over-week improvement) something shifts. Progress becomes real. There’s something to work toward besides quota.
That’s what keeps people in seats long enough to produce.
Turnover is expensive. It’s also fixable.
Not with better perks. With giving reps a real way to get better, before they decide staying isn’t worth it.
