A stay bonus (also called a retention bonus) is a one-time payment for staying through a specific transition — typically a sale, a winddown, a merger close, or a critical handoff. Severance is a payment for leaving. The two often appear together: "stay through [date] and we will pay you [stay bonus]; if you are not retained by the acquirer, we will also pay you [severance]."
The tradeoff is real money. The question is whether the stay bonus is enough to offset the opportunity cost of not job-searching during the stay period.
What a stay bonus typically buys the employer
- Continuity during a sensitive transition. Sales, acquisitions, layoffs, ERP migrations — the employer cannot afford disruption.
- Knowledge transfer. You document what you know before you go.
- Reduced search cost for replacements. They get to hire on their timeline, not yours.
- Protection against competing employer poaching. You cannot move to a competitor while collecting the stay bonus.
What a stay bonus typically costs the employee
- Job-search delay. You cannot pursue other roles seriously during the stay period.
- Stress and reduced engagement. Working through a winddown is harder than starting fresh.
- Some severance offset. Some employers structure the stay bonus to REPLACE severance, not supplement it.
- Tax timing. Lump sum at end of year can push you into a higher bracket.
The math
Compare the stay bonus, after-tax, to:
- Severance you could negotiate today if you exited now (often 2-8 weeks).
- The expected value of new income if you started a job search today. For someone with 6+ years of experience, the typical search takes 3-6 months.
- The opportunity cost of delayed retirement, equity vesting, and benefits coordination at the new role.
If the stay bonus is less than the after-tax value of [severance now + earlier start at new role], decline the stay bonus and negotiate severance.
Scripts to use
To request a stay bonus on top of severance:
"I am willing to stay through [date] to complete the transition. In exchange, I am asking for: (a) a retention bonus of [$X] payable at the end of the stay period, (b) protection of my severance entitlement if I am not retained at the close, (c) accelerated vesting of [equity grant] tied to either the stay completion or the transition close, whichever is later."
To ensure the stay bonus does not offset severance:
"Please confirm in writing that the proposed stay bonus is in addition to, not in lieu of, any severance I may be entitled to under [the severance plan / separation agreement / offer letter]. I am not willing to forfeit severance in exchange for a stay bonus."
To negotiate around layoff risk during the stay:
"If the stay period ends in a layoff or the role is eliminated before [date], please confirm that I will receive both the stay bonus and full severance under the plan. Otherwise the stay bonus is a one-way bet for the employer."
To shorten the stay or allow earlier exit:
"Please add a 30-day notice provision: if I find another role before [date], I can give 30 days' notice and receive a pro-rated portion of the stay bonus based on actual time served."
What to document
- The proposed stay bonus offer, in writing
- The conditions for payment (completion of stay period, no resignation, no for-cause termination)
- Whether the stay bonus offsets or supplements severance
- The interaction with any equity vesting acceleration
- Tax withholding and timing of payment
- The treatment in the event of layoff or role elimination during the stay
When to escalate
For high-value stay bonuses or complex transactions:
- Consult an employment attorney with M&A or executive compensation experience. The economic decision is often material, and the contract terms (forfeiture clauses, restrictive covenants, change-of-control overlay) can significantly affect the outcome.
- For senior employees, the stay bonus is often part of a broader exit package that includes equity acceleration, COBRA, outplacement, and reference terms. Negotiate the whole package, not just the stay bonus.
- For acquisitions specifically, the acquirer's intent to retain you is the most important variable. If retention is uncertain, the stay bonus needs to be larger to offset that risk.
The decision is often less about the bonus number and more about the structure: payment timing, forfeiture conditions, interaction with severance, and protection against layoff during the stay period. Get the structure right and the number tends to work itself out.
