Merit Matrix

The grid companies use to determine annual raise percentages based on two inputs: an employee's performance rating and where their current salary falls within the salary range for their role.

A merit matrix (also called a pay increase matrix or salary increase matrix) is the structured tool HR teams use to calibrate annual merit increases across the workforce. It defines recommended raise percentages based on two axes: the employee's performance rating (typically a 3-5 point scale) and their position in range — where their current salary falls relative to the salary range midpoint for their role (often measured by compa-ratio or as a 'quartile' of the range). The matrix outputs a recommended increase percentage that reflects both individual performance and pay equity considerations — rewarding high performers while also addressing employees who are paid below market midpoint, regardless of performance.

The logic behind the two-axis design reflects a fundamental HR principle: merit increases should reward performance AND address pay equity simultaneously. A high performer who is already paid at the 90th percentile of their range needs a smaller percentage increase than a high performer paid at the 65th percentile — because the former is already well-compensated relative to market, and further large increases would push them above the range maximum without a corresponding change in scope. A low-to-mid performer who is paid at the 70th percentile of their range also needs a modest increase — their performance doesn't merit a large raise, but they're also not underpaid relative to market, reducing urgency.

In a typical merit matrix, increase percentages vary significantly across the cells. A top performer (rating 5) at the bottom of their range (compa-ratio < 0.85) might receive a 7–9% increase. A top performer at the top of their range (compa-ratio > 1.15) might receive 2–3% — or be considered for a promotion to the next level rather than an in-level increase. A mid-performer at the midpoint of their range might receive 2–3.5% — roughly in line with inflation. A below-standard performer may receive 0–1% or no increase at all. The matrix ensures that finite merit budget is allocated in a way that is explainable, consistent, and aligned with both performance outcomes and internal equity objectives.

Employees rarely see the merit matrix directly, but its logic plays out in every annual review. Understanding how it works helps demystify why two employees with the same performance rating receive different percentage increases, and why a high performer near the top of their band may receive a smaller raise than they expect. It also reveals the mechanism behind a common compensation trap: if your pay was ratcheted up significantly through a competitive offer or a negotiated raise, your compa-ratio may now be high — which caps your merit increase percentage going forward, regardless of performance, until the market range catches up or you are promoted to the next level.

How a Merit Matrix Works

  • Two inputs: performance rating (from annual review) and position in range (compa-ratio or quartile — where your pay sits relative to the salary range for your role and level).
  • Output: a recommended merit increase percentage — not a fixed dollar amount, but a percentage applied to current base salary.
  • Higher increases for lower compa-ratios: employees paid below the range midpoint receive higher percentage increases to move toward market — independent of performance, to address pay equity.
  • Lower increases for higher compa-ratios: employees paid above the range midpoint receive smaller increases even if performance is strong — to avoid pushing pay above the range maximum.
  • Zero increases for below-standard performers: most matrices set 0% for employees who fall into 'does not meet expectations' — merit increase is contingent on meeting a performance threshold.
  • Budget constraint: the overall merit pool (typically 2-5% of total payroll) constrains average increases; the matrix calibrates distribution within that constraint.

Sample Merit Matrix Structure

Reading a merit matrix: rows are performance ratings (5 = Exceptional, 4 = Exceeds, 3 = Meets, 2 = Below, 1 = Unsatisfactory); columns are position in salary range (Q1 = bottom 25%, Q2 = 25-50%, Q3 = 50-75%, Q4 = top 25%).

  • Rating 5, Q1 (top performer, bottom of range): 8–10% — addressing both outstanding performance AND significant pay gap.
  • Rating 5, Q2: 6–8% — still large increase, some pay equity work to do.
  • Rating 5, Q3: 4–6% — good increase for strong performance; pay is at or near midpoint.
  • Rating 5, Q4 (top performer, top of range): 2–3% — strong performer but already well-paid; promotion may be more appropriate than in-level increase.
  • Rating 3, Q1 (meets expectations, bottom of range): 3–5% — moderate increase; pay needs to move toward midpoint even with average performance.
  • Rating 3, Q4 (meets expectations, top of range): 0–1% — average performance, already well-paid; minimal increase.
  • Rating 1-2 (below standard): 0% across all positions in range — performance threshold not met.

What This Means for Employees

  • High compa-ratio caps your merit increase: if you negotiated a high starting salary or received large raises, your compa-ratio is high — which suppresses future merit increases until market ranges catch up or you're promoted.
  • Promotion resets the clock: moving to the next level resets your compa-ratio (you enter the new, higher range near the bottom) — often the fastest path to significant compensation growth.
  • Performance rating is only one input: two colleagues with the same '5 – Exceptional' rating can receive very different raises if their compa-ratios differ significantly.
  • Understanding your compa-ratio: ask HR or your manager, 'Can you tell me where my current salary falls within the range for my level?' — this gives you the key input to understand your merit increase potential.
  • Advocating for promotion timing: if your compa-ratio is high and you're performing strongly, the explicit argument is 'I believe my contributions are at the next level — a promotion to the new range is the mechanism to appropriately compensate the work I'm already doing.'

Example

Two engineers both receive a '4 – Exceeds Expectations' performance rating in the annual review. Engineer A joined last year at a negotiated salary that puts her in Q3 of the range (compa-ratio 1.05). Engineer B joined 4 years ago at a lower salary and, despite steady raises, sits in Q1 (compa-ratio 0.82). The merit matrix recommends 3.5% for A and 7% for B. A receives a $5,600 raise on her $160,000 base; B receives an $8,400 raise on his $120,000 base. A notices the disparity and is frustrated — but the matrix logic is that B's pay is below market midpoint for the role and the increase addresses both pay equity and performance recognition. A's path to larger increases is promotion to the next level, not a higher in-level raise.
