Why it matters
Decisions about retention investment decisions commit real resources, so planning them explicitly — with stated assumptions — beats reacting. A shared framework makes trade-offs visible and decisions defensible, without pretending to know costs you must supply yourself.
The method is portable; the numbers are yours.
Key concepts
- The cost of turnover (your figures).
- Comparing retention investment to that cost.
- Where retention pays back.
- Conservative assumptions.
Operational framework
- Start from goals and the decision you face.
- Translate goals into roles, capacity or investment.
- State your assumptions explicitly.
- Quantify with your own figures in the calculators.
- Review against outcomes and adjust.
Assumptions & allocation
- Your estimated cost per departure.
- Expected departures.
- Cost of retention actions.
- How conservative to be.
Common challenges
- Treating turnover cost as precise.
- Borrowing benchmark figures.
- Over-investing without diagnosis.
- No review.
Best practices
- Estimate turnover cost with your figures.
- Diagnose before investing.
- Compare investment to estimated cost.
- Set retention governance.
Common mistakes
- Using benchmark turnover cost.
- Investing without diagnosis.
- Overstating savings.
- No review.
Measure this with the employee retention rate metric, put it into practice with the stay interview template, and run it as a system via operationalising employee retention.
