How to Build a Salary Structure from Scratch

Grades, Ranges, and the Governance That Makes It Work

Loading voice engine…

Without a salary structure, pay decisions default to whoever negotiates hardest. With one, pay becomes consistent, defensible, and fair. Building a salary structure is one of the most impactful technical skills a compensation professional can develop — and it is more accessible than most people assume.

What a Salary Structure Is — and Is Not

A salary structure is a hierarchy of salary grades, each with a defined minimum, midpoint, and maximum pay range. When a role is placed in Grade 4, everyone immediately knows what range applies — without negotiating from scratch for every hire or promotion. Structures create internal equity by ensuring comparable roles receive comparable treatment, external competitiveness by anchoring ranges to market data, and governance by defining what falls within policy.

A salary structure is not a guarantee that everyone is paid at the midpoint. It is not a ceiling preventing exceptional pay for exceptional performance. It is a governance tool that makes every pay decision faster, more consistent, and more defensible — and that makes auditing for equity far more straightforward.

Anatomy of a Salary Range
Minimum → entry/developing employee Midpoint → fully competent employee; market reference rate Maximum → highly experienced; ceiling of the grade

Step 1: Evaluate the Jobs and Step 2: Gather Market Data

Before building ranges, understand the relative size of every role through job evaluation — assessing each on knowledge required, complexity, accountability, and impact. Roles with similar scores are grouped into the same grade regardless of function or title. This internal hierarchy becomes the foundation of the structure.

Once grades are established, anchor them to the external market. Collect salary survey data for benchmark roles at each grade level, match by role content rather than title, and identify the market P50 for each. Plot the data points with grade on the x-axis and salary on the y-axis. The regression line through these points — your pay policy line — shows the mathematical relationship between role size and target pay at your chosen market position.

Step 3: Design Grades and Ranges

Using your pay policy line, set midpoints for each grade with a consistent 15 to 20 percent progression between adjacent grades. Build ranges around each midpoint: 40 to 50 percent spread for junior grades, 60 to 70 percent for senior grades. The minimum typically sits at 80 percent of midpoint and the maximum at 120 percent for a 50 percent spread.

Ensure adjacent grades overlap appropriately — where the maximum of Grade 3 slightly exceeds the minimum of Grade 4. This means an experienced Grade 3 can legitimately earn more than a new Grade 4, reflecting that within-grade experience and performance are genuine differentiators.

Range Spread Formula
(Maximum − Minimum) ÷ Minimum × 100 Junior roles: 40-50% | Senior roles: 60-70%

Step 4: Address Outliers and Build Governance

Place every role into its grade. Then audit current salaries: employees below range minimum are green-circled (underpaid — require prompt resolution). Those above maximum are red-circled (overpaid relative to the grade — typically managed by freezing increases until the range catches up). Document every outlier with a resolution plan.

Governance is what makes a structure work over time. Define who can approve exceptions, how new roles are evaluated and placed, when market adjustments are triggered, and how frequently midpoints are reviewed against market movement. Without governance, a well-designed structure will drift out of alignment within three years.

Scenario
Castleton Partners Builds From Scratch
Castleton Partners, a 300-person professional services firm, had paid on negotiation for ten years. An internal audit found two Senior Analysts doing identical work earning $64,000 and $89,000 — a 39% gap with no documented justification. HR ran point-factor evaluation across all 85 distinct roles, gathered survey data from two benchmarks, and built a seven-grade structure anchored to P50. Implementation took nine months total. Within a year, the average gap between comparable roles had narrowed from 28% to 6%, and voluntary turnover among mid-level professionals fell 18%.

Three Common Mistakes to Avoid

01
Copying another organization's structure
Structures reflect your job architecture, market, and culture. A copied structure may have grades that do not match your roles, ranges misaligned to your market, and a philosophy that does not fit your talent strategy.
02
Too many or too few grades
Ten grades for a 50-person company creates needless complexity. Three grades for 500 people with significant role diversity creates compression and inequity. Match grade count to your genuine role hierarchy.
03
Building it once and never reviewing
Markets move and roles evolve. A structure that was right at launch will drift from market reality within three years without annual midpoint reviews.
Your Action Steps
Audit Your Current Salary Structure
1Calculate compa-ratio (salary ÷ midpoint × 100) for every employee. Anyone below 80 or above 120 is outside the normal functioning range and needs a documented resolution plan.
2Check when midpoints were last updated against market data. If more than 18 months ago, the structure may be losing competitiveness.
3Count your grade levels. If you have more than one grade per 150 employees, consider whether consolidation would simplify decisions without losing meaningful differentiation.
4Identify your target market percentile for each grade. Is it consistent and documented?
A salary structure does not tell you exactly what to pay every person — it tells you what range is appropriate, ensuring every decision is made within a logical, defensible framework.

Key Takeaways
  • A salary structure groups roles into grades with defined ranges — creating consistency, fairness, and defensibility.
  • Build from job evaluation (internal equity) and market data (external competitiveness) simultaneously.
  • Range midpoints should be anchored to market P50 with 15 to 20 percent consistent progression between grades.
  • Annual midpoint reviews maintain competitiveness as markets move — structures without reviews drift out of alignment within three years.
