Exit Interviews: The Cheapest Retention Tool You’re Not Using
I talk to a lot of small business owners who, the moment someone hands in a resignation letter, are ready to be done with them. I get it. You're disappointed, maybe a little annoyed, and part of you just wants them out the door. But when we treat a resignation as the end of the relationship, we walk away from some of the most honest feedback we'll ever get about our own companies.
And the stakes are real. Gallup estimates that replacing an employee costs anywhere from one-half to two times their annual salary once you add up recruiting, onboarding, training, and lost productivity. Every person who walks out the door is expensive. The least we can do is learn something from it — and that's exactly what an exit interview is for.
The Intel You're Walking Away From
An exit interview mines information you can't get any other way. Start with the obvious question: why did they really leave? During the resignation process, people rarely tell you the whole truth — they don't want to burn a bridge. But once they're gone, talking to a neutral third party, they tend to open up.
You'll also learn things you'd never think to ask directly. Was our training actually any good? Did our benefits matter to you? What's broken that we keep stepping around? I've found you even get an honest read on your leaders. Sometimes you find out a manager is so good that they're the thing this person will miss most. Other times you find out the opposite — and that's just as valuable to know.
It's Also About Goodwill
Here's the part I think owners underestimate: how someone leaves shapes what they say about you afterward. Departing employees talk to others in your industry about whether your company is a good place to work. We always tell employees to leave well — but I'd tell employers the same thing. Be gracious on the way out, because it protects your reputation.
An exit interview quietly says, "What you have to say still matters, even now." If they'd rather not vent, that's fine — but giving them the chance builds real goodwill. It even opens a door: "You did great work here. If you ever meet someone who'd be a great fit, send them our way." A respected former employee can become one of your best sources of referrals.
The Three Questions I Always Ask
You don't need a complicated script. Honestly, I often lean on just three questions:
What was going well?
What wasn't going well?
If you were king for a day, what would you change?
Those three prompts alone tend to surface pure gold.
How to Do It Right
A few ground rules separate a useful exit interview from a wasted one:
Do it with everyone. Not just the departures you're worried about. Pick a start date — "as of July 1, everyone gets an exit interview" — so it never feels targeted.
Do it after their last day. A little distance makes people more candid.
Use a third party. This is the big one. People couch their answers with the CEO or the HR leader, but they'll tell the truth to an outsider — a skilled business coach, a trusted friend of the company, or a firm that does this for a living. We run exit interviews for a lot of our clients for exactly this reason.
Be clear about the rules. Tell them it's coming, that it's optional but valued, and that their feedback will go back to leadership. Anything truly confidential can stay with the third party.
The Bottom Line
Exit interviews cost almost nothing and hand you a steady stream of honest feedback about what's working, what isn't, and what your best people wish you'd change. And retention — keeping the good people you already have — is where great companies are built.
