Merit increases work best when they’re treated as a repeatable decision process, not a once-a-year scramble. A good process balances three things: rewarding performance, managing internal equity, and staying within budget while producing outcomes leaders can explain with a straight face.

This article lays out a practical step-by-step approach, includes calibration tips, shows merit matrix examples (performance × compa-ratio), and calls out common mistakes. It uses familiar local terms like superannuation, TRP/package, remuneration, and pay bands without overdoing it.

Key Definitions (keep everyone aligned)

• Merit increase: an increase to base salary (not a bonus/one-off), typically linked to performance and position in range.
• Pay band / salary range: minimum–midpoint–maximum for a role/level.
• Midpoint: the market anchor for someone fully proficient at level.
• Compa-ratio: employee base salary ÷ range midpoint.
• TRP / package: often base + super (definitions vary by organisation be clear internally).

Tip: Run your process in base salary first, then convert communications to package/TRP if that’s how you offer.

Step-by-Step Merit Increase Process

Step 1: Set the merit budget and guardrails

Before managers touch spreadsheets, clarify:

• Total merit budget (e.g., 3.0% of eligible payroll)
• Eligibility rules (new starters, probation, performance improvement plans, contractors)
• Minimum/maximum increase guidance (e.g., 0% to 6% typical; exceptions require approval)
• Treatment of employees over range max (e.g., limited base increase; use one-off award)
• How promotions and market adjustments interact (avoid double-dipping or missing critical fixes)

Practical guardrail examples

• Promotions are handled separately from merit (recommended).
• Market adjustments are handled separately (recommended).
• Merit is for performance and progression within the level.

Step 2: Confirm salary ranges and midpoint accuracy

Merit decisions rely on compa-ratio so if midpoints are out of date, your matrix will misfire.

Quick checks:

• Have ranges been refreshed in the last 12 months?
• Are key roles (hard-to-hire, fast-moving markets) still aligned to reality?
• Are you consistently using base vs TRP?

If you can’t refresh everything, at least validate midpoints for your priority families.

Step 3: Finalise performance ratings (with evidence)

Merit is only as fair as your performance input.

Do a quick quality check before money is allocated:

• Are rating definitions clear (e.g., “Exceeds” means what, exactly)?
• Are there teams with suspiciously high/low distributions?
• Are ratings consistent across similar roles/levels?

Practical tip: Ask managers for 2–3 evidence bullets per person tied to goals/impact. It helps reduce recency bias and makes calibration faster.

Step 4: Calculate compa-ratios and identify “must review” cases

For each eligible employee:

• Compa-ratio = base salary ÷ midpoint

Flag common cases for review:

• <0.85: likely low in range (potential internal equity risk)

• 1.15: high in range (may indicate promotion readiness or range max pressure)

• Above max: needs policy-driven approach (often one-off rather than base increase)
• Compression: newer hires paid close to or above longer-tenured incumbents

This is where you prevent the process from being purely “performance-only” and accidentally worsening inequity.

Step 5: Build your merit matrix (performance × compa-ratio)

A merit matrix gives managers consistent starting points. It does not remove judgement—but it makes judgement structured.

Simple 3×3 example (illustrative)

Compa-ratio bands

• Low: <0.90
• Mid: 0.90–1.10
• High: >1.10

Performance

• Needs Improvement
• Meets Expectations
• Exceeds Expectations

Merit matrix (increase % of base salary)

Performance \ Compa-ratio	Low (<0.90)	Mid (0.90-1.10)	High (>1.10)
Exceeds Expectations	4.5%-6.0%	3.5%-5.0%	2.0%-3.5%
Meets Expectations	3.0%-4.0%	2.0%-3.0%	0.5%-2.0%
Needs Improvement	0%-1.0%	0%	0%

How to use it

• It naturally gives bigger increases to strong performers who are low in range (often the most retention-sensitive group).
• It controls increases for employees already high in range unless performance is exceptional.
• It gives a consistent approach for low performance (often 0% base increase).

4×4 example (more control, common in larger orgs)

Performance: Below / Meets / Strong / Outstanding

Compa-ratio bands: <0.85 / 0.85–1.00 / 1.00–1.15 / >1.15

Performance \ Compa-ratio	<0.85	0.85-1.00	1.00-1.15	>1.15
Outstanding	6%-8%	5%-7%	3%-5%	2%-4%
Strong	5%-7%	4%-6%	2.5%-4%	1%-2.5%
Meets	3%-5%	2%-4%	1%-2.5%	0%-1%
Below	0%-1%	0%	0%	0%

Budget tip: You can tune these ranges to match your overall merit pool by adjusting the middle cells first.

Step 6: Managers propose increases using the matrix + justification

Have managers submit:

• Proposed % increase (or dollar)
• Performance rating
• Compa-ratio and range position
• Short rationale (2–3 bullet points)
• Flag if any exception (e.g., retention risk, skill scarcity, internal equity fix)

Practical guidance managers understand

• Merit ≠ promotion
• Merit rewards performance at current scope
• If someone is consistently at the top of the range and still growing, that’s a promotion conversation, not endless merit at max

Step 7: Run calibration sessions (this is where fairness happens)

Calibration is how you prevent “easy graders” and “hard graders” from creating pay inequity.

Calibration tips that actually work

1. Start with distributions, not individuals
   • Compare rating distributions by team, level, and function.
2. Use prompts that focus on impact
   • “What changed because of this person’s work?”
   • “How does their impact compare to peers at the same level?”
3. Watch for bias patterns
   • Recency bias (last two months overweighted)
   • Like-me bias
   • Visibility bias (loud work rewarded over high-impact quiet work)
4. Check for pay equity drift
   • If two people are similar performance/level but compa-ratios are wildly different, ask why.
5. Calibrate exceptions centrally
   • Create a short list of “exception requests” and review them consistently.

A simple calibration agenda (60–90 minutes)

• Review merit matrix rules and budget
• Review team distributions (ratings + proposed increases)
• Review outliers (very high increases, 0% increases, above-max cases)
• Confirm equity checks (compression flags, protected group checks where appropriate)
• Lock outcomes and document exceptions

Step 8: Final approval + payroll implementation

Before you lock:

• Ensure totals match budget (include on-cost considerations if needed)
• Confirm compliance with any award/enterprise agreement constraints (where applicable)
• Validate that salary changes won’t create new inversions (manager/direct report anomalies, etc.)
• Confirm effective dates and pro-rating rules

Then feed into payroll/HRIS and prepare manager comms.

Step 9: Communicate clearly (and consistently)

Managers should be able to explain:

• performance outcome (what drove it)
• how pay positioning influenced the decision
• what the employee can do to progress next cycle

Avoid over-sharing formulas, but do give a consistent narrative:

• “Merit reflects performance and where you sit within the pay band.”

If your org communicates in package/TRP, convert numbers carefully and explain superannuation clearly.

Common Mistakes (and how to avoid them)

1. Mixing merit with promotions
   • Result: inconsistent increases and budget blowouts.
   • Fix: separate promotion increases from merit.
2. Using ratings without calibration
   • Result: inequity across teams; morale issues.
   • Fix: run calibration sessions with shared standards.
3. Treating the matrix as a strict rule
   • Result: managers stop thinking; edge cases handled badly.
   • Fix: matrix is a starting point; require justification for exceptions.
4. Ignoring compa-ratio / range position
   • Result: inequity drift and retention risk (especially for underpaid strong performers).
   • Fix: always review low-in-range high performers.
5. Overpaying at the top of the band
   • Result: you hit range maximums and have nowhere to go.
   • Fix: use promotion paths or one-offs; review role scope.
6. Letting “retention” become a loophole
   • Result: the best negotiators win, not the best performers.
   • Fix: define scarcity/retention criteria and approve centrally.
7. Not pressure-testing outcomes for compression
   • Result: new hires paid close to incumbents, causing disengagement.
   • Fix: check compression and adjust thoughtfully (sometimes via targeted equity/market adjustments).

Practical “Merit Process Starter Kit” (copy/paste)

Inputs

• Updated pay bands (min–mid–max)
• Final ratings (and definitions)
• Eligible employee list
• Merit pool % and rules
• Compa-ratio calculation

Outputs

• Proposed increases by manager
• Exception list + rationale
• Calibrated final increases
• Communication talking points

Governance

• One matrix across the org (or per job family if markets differ significantly)
• Central review of exceptions
• Post-cycle review: What changed? Where did the matrix break?

Optional: A Simple Post-Cycle Review (so next year is easier)

After implementation, review:

• How many people moved closer to midpoint?
• Where did you see the most exceptions (and why)?
• Did you worsen or reduce compression?
• Are any pay bands now clearly out of date?

This closes the loop and improves the structure over time.
