An employer’s guide to retention bonuses
By Laura Ojeda Melchor●9 min. read●Jan 26, 2026
Offering an employee a retention bonus is a significant investment. You're handing over a chunk of cash to an employee in exchange for their commitment to staying with your company.
But this incentive can be the difference between keeping a valuable team member and losing them to a competitor. And the cost of losing an employee goes far beyond the price of hiring a replacement.
In this guide, you'll learn how retention bonuses work, how much to offer, and how to structure a program that keeps your best people in place.
Key takeaways
Definition: A retention bonus is a financial incentive (usually 10 to 30% of salary) paid to employees to ensure they stay for a specific period.
Strategic use: These bonuses are most effective during mergers, acquisitions, leadership changes, or key product development and sales seasons.
Cost-effectiveness: Retaining a high performer is significantly cheaper than replacing one, which can cost 2X an employee's annual salary.
Structure: Bonuses can be paid as a one-time lump sum or as "retention pay" distributed in installments to encourage longer-term commitment.
Taxation: The IRS classifies these as supplemental wages, typically subject to a flat 22% federal withholding rate.
What is a retention bonus?
A retention bonus (or stay bonus) is a financial incentive meant to keep employees on the job for a set period. It's usually a cash reward in a generous amount, typically around 10-30% of the employee's salary.
Unlike a performance-based employee bonus program, the purpose of a retention incentive is to reduce turnover and retain workers. This type of bonus is considered an ERB (employee retention benefit).
Retention bonuses can be paid out in a lump sum or installments during the agreed-upon time frame. This pay is separate from an employee's regular compensation and is considered supplemental wages by the IRS.
These financial incentives are often used in five key situations:
During a merger or acquisition to retain key employees and keep things stable as a company undergoes major changes.
To retain high-performing employees in specialized or hard-to-fill roles.
When a key employee receives a competing job offer to retain a valuable team member.
During leadership changes or restructuring to prevent turnover during big company-wide changes.
For project-based retention to keep key employees committed until a major launch or expansion is complete.
Retention pay vs. retention bonus
The terms retention pay and retention bonus are often used interchangeably. Both refer to financial incentives designed to keep employees from leaving, but companies might use the terms differently depending on their retention strategy.
A retention bonus refers to a one-time lump-sum payment given to an employee after they stay with the company for an agreed-upon period.
Retention pay refers to a structured, ongoing incentive rather than a single payout. It's essentially a retention bonus distributed in installments instead of one lump sum.
Because the payments are stretched out, retention pay can incentivize employees to stick around longer than a single retention bonus.
How much should a retention incentive be?
A retention incentive can range from 10% to 30% of an employee's annual salary. The size depends on a number of factors, including the employee's role, the length of the retention period, and the company's budget.
| Role type | Typical range | When to use |
|---|---|---|
| High-risk or critical roles | 20-30% of salary | During M&A, restructuring, or when departure would significantly impact operations |
| Hard-to-hire specialists | 15-25% of salary | For roles requiring 6+ months to fill or specialized expertise |
| Seasonal or short-term coverage | $1,000-$5,000 flat amount | To retain hourly or frontline workers through peak periods |
| Executives during M&A | 25-50% of salary or milestone tranches | When leadership continuity is essential to deal success |
The key is to offer an amount significant enough to motivate the employee to stick around without pushing your HR budget.

Benefits of retention pay
Retention pay can be a win-win for both employers and employees. Employees get extra financial security, and employers hold on to key team members longer.
When employees leave, they take valuable institutional knowledge and client relationships with them. According to Gallup, the true cost of replacing an employee can be up to two times their annual salary. A single departure can stall projects, slow production, and even delay product launches. Worse, it can dampen morale and trigger the rest of the team to start their own job searches.
Let’s put this into perspective with an example scenario. Say a company has 750 employees and a turnover rate of 15%. Between recruiting costs and training time, they’re losing $3,000 on average every time an employee leaves.
That adds up to $339,000 in annual turnover costs. And that's before accounting for downstream effects on productivity and company culture.
Here’s what could happen if this company offered a retention incentive:
| Metric | Without retention pay | With retention pay |
|---|---|---|
| Annual turnover (employees) | 112 | 78 (30% reduction) |
| Cost per departure | $3,000 | $3,000 |
| Annual turnover cost | $339,000 | $237,000 |
| Retention bonus investment | $0 | $170,000 (34 employees × $5,000) |
| Net savings | — | $102,000 |
A retention incentive requires an upfront investment, but it’s worth the long-term benefits.
What to include in a retention bonus agreement?
A retention incentive begins with a formal agreement that outlines the terms to employees. This agreement should specify:
The bonus amount and how it was calculated
The retention period (how long the employee must stay to receive the bonus)
Any specific performance expectations or goals the employee must meet
Payment terms (lump sum vs. installments)
Tax implications and withholding details
If the employee fulfills the terms, they receive the bonus. If they leave before the retention period ends, they forfeit it.
How to design and launch a retention bonus program
Here’s how to set up a retention program in a few steps.
1. Figure out who’s eligible
Picking which employees are the most crucial to your organization is a tough task, so make your process as objective as possible. A few key factors to consider include:
Performance metrics: Review your entire team’s productivity and key performance indicators (KPIs). Who stands out?
Specialized skills and expertise: Consider which employees have unique skills and experience that make them hard to replace.
Influence: Include employees who play an important role in mentoring other team members or improving morale as well.
Business impact: Identify which employees’ work directly contributes to revenue, customer satisfaction, or operational success.
Retention risk: Assess which team members are more likely to leave. Is there a high demand for their skills? Is job satisfaction faltering? Have they received a recent offer from a competitor?
Project and role dependency: Identify team members who are essential to ongoing projects or hold critical positions within your company.
2. Decide on a bonus structure
The next step is to choose a bonus structure that makes sense. Will you offer a flat amount or a percentage of a person's salary? Will you offer a lump sum payment or installments? There are no strict rules to follow here, so do what feels right for your organization.
For instance, you can offer tiered bonuses based on an employee's level or role in the company. Or you can spread the money out in installments as retention pay to help incentivize long-term loyalty. Just make sure the payment structure works for your budget before you set it in stone.
3. Create an employee retention bonus agreement
Work with your in-house counsel or use a legal service to create a formal retention bonus agreement. This document should specify:
The bonus amount and how it was calculated
The retention period (how long the employee must stay to receive the bonus)
Any specific performance expectations or goals the employee must meet
Payment terms (lump sum vs. installments)
Tax implications and withholding details
Forfeiture conditions outlining what happens if the employee leaves or is terminated before the retention period ends.
If the employee fulfills the terms, they receive the bonus. If they leave early, they forfeit it — so make sure these conditions are clearly defined.
Review the contract with legal counsel to ensure it follows all relevant local, state, and federal laws before presenting it to employees.
4. Share the details with eligible employees
Schedule one-on-one meetings to discuss retention incentive pay with each eligible employee. Be transparent about why you're offering the bonus and what you expect from them in return.
Follow up each meeting with written documentation for both the employee's and your company's records.
5. Monitor the program's effectiveness
Once you enroll employees, keep track of retention rates among bonus recipients. This data will help you understand whether your investment is working.
Consider sending out monthly or quarterly surveys to gauge employee satisfaction with the program. Ask for suggestions to improve your retention pay incentive and your workplace overall.
Who is eligible for retention payments?
Retention pay is often offered to executives and highly skilled employees who would be difficult to replace. But it can be used to retain all types of workers at any level, including:
Software engineers and data scientists with specialized knowledge of a company's proprietary systems
Sales representatives with strong client relationships
Project managers overseeing a critical, long-term initiative
Retail store managers and associates with a proven track record of driving sales
According to a Mercer study on M&A retention, companies are offering retention pay to 35% of workers who are not necessarily critical for integration. The bottom line? Stay bonuses are often more cost-effective than hiring, onboarding, and training new employees.
When not to offer a retention bonus
Retention bonuses aren't the right solution for every situation. Here's when you might want to reconsider:
Performance issues: If an employee is underperforming, a retention bonus won't fix the underlying problem. You may end up paying to keep someone who isn't contributing meaningfully to your organization's goals.
Cultural misalignment: An employee who doesn't fit your company culture can negatively impact team morale, even if they have valuable skills. A retention bonus can prolong a bad situation.
Blanket offers: Offering retention bonuses to everyone dilutes their impact and signals to employees that the incentive isn't tied to their individual value. Make offers strategically.
Legal and tax implications of retention bonuses
Retention incentives come with specific legal and tax considerations. The IRS views retention incentive pay as supplemental wages to an employee's base pay, just like commissions, overtime, and other types of bonuses. This means employers must withhold taxes on retention pay.
Here's a quick breakdown of the rules:
Flat-rate withholding: If a retention sum is paid separately from regular wages or clearly identified in the same paycheck, the IRS requires a flat 22% withholding rate. This is the easiest and clearest way to withhold taxes. For supplemental wages exceeding $1 million in a calendar year, the rate jumps to 37%.
Aggregate method: If the bonus is combined with regular wages in a single payment and isn't separately identified, withholding is based on the employee’s W-4 and the IRS tax tables.
Social Security & Medicare taxes: Regardless of the payment method, bonuses are subject to Social Security tax (6.2%) and Medicare tax (1.45%). If an employee's salary exceeds the Social Security wage base, only Medicare tax applies.
State supplemental rates vary. Many states have their own supplemental wage withholding rates, which can range from zero (in states without income tax) to over 10% in states like California.
Keep in mind that withholdings don’t determine what taxes employees ultimately owe. That depends on their total income for the year. Employees may receive a refund or owe additional taxes when they file.
For more guidance, check out IRS Publication 15, Employer’s Tax Guide and IRS Publication 15-T for withholding tables, which lay out the rules in detail. Seek advice from tax and legal advisors to stay compliant.
Summary
A well-designed retention bonus program can protect your organization from costly turnover and keep your best people focused on what matters. Pair it with a streamlined payout platform, and you'll save your HR team time while showing employees you value their commitment.
