The impact
The number to take upstairs
This isn't a quote and it isn't a scare number. Here's the logic: some of your people will leave this year by choice. Gallup finds about half of them could have been kept. How much of that half traces back to their manager depends on how well your managers are actually supported — which is the thing you just scored. Multiply that by what it costs to replace someone, and you have a number.
Every step is in the table below, and two of the inputs are yours to change. A number your CFO can audit is worth more than one they have to take on faith.
$186K a year
That's the conservative end. At the top of Gallup's published range it's $745K. Your average team size is 5.3 people per manager.
| People who report to a managerYour headcount minus your managers. These are the people whose experience your managers shape. | 210 of 250 |
| …who leave voluntarily each yearAt 13% annual voluntary turnover — a US all-industry working figure. Put your real one in below. | 27 |
| …that were preventableGallup: 52% of departing employees say their company could have prevented their exit. | 14 |
| …that trace to manager capability35% of the preventable group, based on where you scored. This one is our assumption, not Gallup's. | 5 |
| Cost to replace one of themGallup puts replacement at 0.5–2× annual salary. This uses the floor, on an average salary of $75,000. | $37,500 |
| Estimated annual cost of the manager gap | $186,323 |
These two are our defaults. Yours are better — change them and everything above updates.
Argue with this number. That's what it's for. Every input is on the table above, and two of them are yours to change. Right now it's using a generic 13% turnover rate — you know your real one, and it's the single biggest lever here. We used Gallup's floor for replacement cost on purpose: a number your CFO can't wave off is worth more than a big one.
