Retention bonus
A retention bonus is a payment offered to an existing employee in exchange for staying through a defined period — typically 6-24 months. Used when the company expects the employee might leave and wants to bridge a specific transition.
When retention bonuses are used
The legitimate cases:
- Acquisition transition: keeping key employees through and past a merger or acquisition. Often the largest retention budgets sit here.
- Critical-project completion: a specific deliverable (a system migration, a fundraise close) where leaving mid-project would be costly.
- Counter-offer to a known competing offer: the company knows the employee has another offer and wants to bridge the moment when leaving feels easier.
Outside these specific cases, retention bonuses are usually a sign of an underlying compensation or engagement problem the bonus won’t fix.
What signals retention bonuses send
Two effects beyond the payment itself:
- Public knowledge of who got one creates resentment. If three engineers get a retention bonus and five don’t, the five wonder if they were less valued. Retention bonuses should be confidential by structure (one-off, signed, not announced).
- They can mark the employee for departure, not retention. An employee who has a retention bonus tied to staying through Q3 often plans their departure for Q4. The bonus extended the stay; it didn’t change the decision.
How they’re structured
Typical structures in European SMBs:
- Lump-sum payment at the end of the retention period. 15-25% of annual base.
- Tranched: 25% at start, 25% mid-way, 50% at end. Reduces forfeiture risk.
- Clawback if voluntary departure before the period ends. Same logic as signing bonuses.
