The Peanut Butter Problem: Why Equal Merit Increases Undermine Performance Pay Posted on June 24, 2026 by Michelle Henderson The Peanut Butter Problem: Why Merit Budget Differentiation Is Your Most Important Retention Tool in 2026 8 min read Most organizations say they want to reward performance. Their merit budgets often tell a different story. More than 80% of employers plan to distribute salary increase budgets relatively evenly across the workforce, limiting the distinction between top performers and average contributors. As merit budgets remain tight, that approach makes it harder to reinforce performance, retain key talent, and direct compensation dollars where they have the greatest impact. Merit budget differentiation addresses this challenge by allocating increases based on factors such as performance, market position, and strategic value. In 2026, with average merit increases projected at 3.2%, how organizations allocate their budgets may be more important than the budgets themselves. Why Merit Budget Differentiation Is a 2026 Priority Merit pools shrank slightly in 2026, and shrinking pools force harder choices. According to Mercer’s survey of more than 1,000 U.S. organizations, employers plan to hold base salary increases for merit at 3.2%, with total increases at 3.5% for 2026. With a 3.4% merit budget, there is limited room to both maintain broad increases and create meaningful differentiation for top performers. Organizations that try to do both often end up accomplishing neither. For HR leaders, this is where the challenge becomes practical. Most organizations aren’t choosing between a generous budget and a differentiated one. They’re working with the same constrained budget as everyone else. The question is how those dollars are allocated. When increases are distributed too evenly, top performers may see little difference between their reward and that of an average contributor. Merit budget differentiation doesn’t require a larger budget. It requires making deliberate decisions about where the budget has the greatest impact. How Merit Budget Differentiation Works in Practice Merit budget differentiation does not require a larger budget. It requires a clear framework for allocating available dollars. Organizations take different approaches, but one common method combines performance ratings with compa-ratio, or where an employee sits within their salary range. Using that approach, a merit matrix might look something like this: High performers at or below midpoint: 5–7% increase. These employees deliver strong results and remain below their market target, making additional investment easier to justify. Solid contributors near or at midpoint: 2.5–3.5% increase. Consistent performance at market rate receives a market-rate reward. Employees below expectations or above range maximum: 0–1.5% increase, or a lump-sum award rather than a base pay increase. In these cases, maintaining the integrity of the salary structure may take priority. The weighted average still needs to land within the approved budget. That constraint does not change. What changes is how organizations choose to distribute those dollars. For deeper guidance on the matrix mechanics, see Why You Should Use a Merit Matrix to Align Pay with Performance. The Decision Framework: Four Questions Before You Allocate For HR leaders, the challenge is turning differentiation into actual pay decisions. Before approving an increase, it helps to ask a few simple questions: Does the increase reflect performance? Managers often default to rewarding tenure, effort, or relationships. Calibration discussions can help ensure increases are tied to results rather than individual manager preferences. Where does the employee sit in the pay range? A high performer below midpoint may warrant a larger increase to move closer to market. For an employee already above range midpoint or maximum, a bonus or other reward may make more sense than permanently increasing base pay. Can the decision be supported and documented? Differentiation and pay equity are not at odds, but decisions should be based on clear, consistent criteria that can withstand review. Can the manager explain the decision? If managers cannot clearly explain why one employee received a larger increase than another, the process is probably too complicated or the rationale is not well defined. The specifics will vary by organization, but the underlying principles are the same. Whether you’re managing a merit budget for 50 employees or 5,000, effective differentiation comes down to making deliberate, defensible decisions about where limited dollars will have the greatest impact. What Happens When You Skip Merit Budget Differentiation The retention risk is easy to overlook because it develops gradually. High performers are often the employees with the strongest external opportunities, and when salary increases look largely the same regardless of contribution, they notice. Over time, evenly distributed increases can create another problem: the pay gap between top performers and average performers begins to shrink. After several merit cycles, organizations may find that compensation no longer reflects meaningful differences in performance. At that point, the issue is no longer the size of the merit budget. It’s how the budget has been allocated over time. The broader compensation landscape points in the same direction. According to HR Dive’s reporting on Mercer’s findings, pay growth has increasingly favored higher-wage roles, reflecting a market where employers are placing a premium on specific skills and talent segments rather than applying the same approach across the workforce. Pay transparency adds another layer. With transparency laws now in effect across 17 states and Washington, D.C., employees have greater visibility into salary ranges and pay decisions. Organizations need to be prepared to explain why increases differ, and to show that those decisions are based on clear, consistently applied criteria. Key Takeaways Merit budget differentiation helps organizations reinforce performance without increasing the overall budget. While 83% of employers plan to distribute merit budgets broadly across the workforce in 2026, differentiated approaches can create a clearer link between pay and performance. Many organizations use a combination of performance and compa-ratio to guide merit allocation decisions, though specific approaches vary. Effective differentiation depends on more than a merit matrix. Clear documentation, manager preparation, and consistent decision-making are equally important. As pay transparency requirements expand, organizations need compensation decisions that are both explainable and consistently applied. Quick Implementation Checklist Confirm your approved merit budget and total dollar pool before building a merit matrix. Review compa-ratios for all eligible employees and flag those significantly below or above range midpoint. Build or update your merit matrix using performance and market position as decision factors. Test allocation scenarios to ensure recommendations remain within budget. Hold calibration discussions before managers finalize merit recommendations. Document the criteria used to support differentiated increases. Prepare managers to explain pay decisions clearly and consistently. After the cycle, review outcomes by department and demographic group to identify any unintended patterns. Ready to run a cleaner, more defensible merit cycle?

Frequently Asked Questions For Compensation Professionals Q: What is merit budget differentiation? Merit budget differentiation is the practice of allocating merit increases based on factors such as performance and market position, rather than distributing a fixed budget evenly across all employees. The goal is to direct a greater share of available dollars toward employees whose performance, skills, or market positioning make them a higher retention priority. Q: How do I keep the weighted average within budget when differentiating? Start by assigning increase percentages to each performance tier and compa-ratio band, then model the distribution against your employee population. The goal is to ensure the weighted average remains within the approved budget while still creating meaningful differentiation. Before finalizing recommendations, it’s worth testing a few scenarios to see how different allocations affect the overall budget. MorganHR’s free Merit Matrix Calculator can help you build and validate those scenarios. Q: Should lump-sum payments replace base increases for employees above their range maximum? In many cases, yes. A lump-sum payment can recognize performance without permanently increasing base pay. This helps maintain salary structure integrity while still rewarding employee contributions. Whether a lump sum is appropriate depends on your compensation philosophy, pay structure, and retention objectives. Q: Is a merit matrix the only way to differentiate merit increases? No. Many organizations use merit matrices because they provide a structured way to balance performance and market position, but they are not the only approach. Some organizations place greater emphasis on critical skills, retention risk, succession planning, or business impact. The key is having clear, consistent criteria for how merit dollars are allocated. Q: How does pay transparency affect merit budget differentiation? As employees gain more visibility into pay ranges, organizations need to be prepared to explain why compensation outcomes differ from one employee to another. Effective differentiation is not about making larger increases harder to justify; it’s about ensuring decisions are based on documented, consistently applied criteria that managers can clearly communicate. For Executives and HR Leaders Q: Won’t differentiated increases create perception problems among employees? Not necessarily. Employees are more likely to question pay decisions when the rationale is unclear or inconsistently applied. When organizations have clear criteria and managers can explain how performance, market position, and other factors influenced the decision, differentiated outcomes are often easier to support. Q: How does merit budget differentiation connect to retention strategy? When merit budgets are limited, organizations have to make choices about where increase dollars will have the greatest impact. Merit budget differentiation allows employers to direct a larger share of available dollars toward high performers, critical skills, or employees with greater retention risk. For many organizations, that makes merit planning as much a talent decision as a budgeting exercise. Q: Does this approach scale for large enterprises? Yes. The underlying principles are the same whether an organization has 500 employees or 50,000. The difference is execution. Larger organizations often rely on merit administration tools and structured workflows to manage budgets, improve consistency, and provide visibility into compensation decisions across business units. Regulatory and Compliance Considerations Q: Does merit budget differentiation create pay equity risk? Not inherently. In fact, structured differentiation can strengthen pay equity by ensuring compensation decisions are based on consistent, documented criteria rather than manager discretion alone. The greater risk comes from informal or inconsistent decision-making. Regular calibration and documentation help ensure increases can be explained and supported if questioned. Q: How does pay transparency legislation affect differentiated increases? As employees gain greater visibility into salary ranges, organizations need to be prepared to explain not only where employees fall within a range, but also why increase decisions differ. Factors such as performance, market position, skills, and internal equity may all play a role. The more clearly those factors are defined and communicated, the easier it becomes for managers to have productive compensation conversations.
