The Complete Guide to Compensation Planning and Salary Structures

Most companies get compensation planning wrong. They slap together market data from a free survey, ask managers to “be fair,” and call it a day. Then they wonder why top performers leave for a 10% raise down the street, or why two engineers doing identical work discover they’re paid 40% apart.

Compensation planning isn’t sexy. But it’s the single most impactful financial decision a company makes that directly touches every employee. Get it right, and you retain talent, control costs, and build trust. Get it wrong, and your payroll leaks money into resentment and turnover.

Here’s how to build a compensation structure that works.

Why You Need a Salary Structure, Not Just Salary Numbers

A salary structure is a framework — a set of ranges, grades, and rules that map jobs to pay. Without one, you’re negotiating in the dark. Every new hire becomes a unique snowflake, and every promotion is a guessing game.

A good structure does three things:

• Internal equity — ensures similar roles pay similarly, so no one feels ripped off compared to their teammate.
• Market alignment — ties your pay to what the labor market demands, so you’re competitive but not overpaying.
• Predictability — gives managers clear boundaries, so they don’t accidentally give a junior analyst a senior director’s salary.

The alternative is chaos. And chaos costs more than you think.

Step 1: Benchmark Your Jobs Against Real Market Data

You can’t design a structure without knowing what your roles are worth. That means benchmarking — comparing each job’s responsibilities, level, and location against salary survey data.

Where to get data

• Paid surveys (Radford, Mercer, Willis Towers Watson) — gold standard, but expensive. Best for mid-size to large companies.
• Free/open sources (Levels.fyi, Glassdoor, LinkedIn Salary, Indeed) — noisy but usable for quick checks. Filter by location and experience.
• Custom peer groups — ask 3–5 similar companies to share anonymized salary ranges. Trust-based, but highly relevant.

What to benchmark

Don’t just benchmark the job title. Benchmark the job family, level, and scope. A “Senior Engineer” at a startup is not the same as a “Senior Engineer” at Google. Map your jobs to standard market levels (typically 6–10 grades from entry to executive).

Step 2: Build Pay Grades and Ranges

Once you have market data, group jobs into grades. Each grade gets a salary range with three key numbers:

• Minimum — the floor. You rarely hire below this. It’s typically 85–90% of the midpoint.
• Midpoint — the target. The market rate for a fully competent employee in the role.
• Maximum — the ceiling. Usually 110–120% of the midpoint. Prevents people from topping out too early.

How wide should ranges be?

• Entry-level / individual contributor roles: 30–40% spread (min to max). Narrow because skills don’t vary wildly.
• Manager / senior IC roles: 40–50% spread. More variability in experience and performance.
• Executive roles: 50–60% spread. Performance and impact differ enormously at that level.

Rule of thumb: Overlap between grades

Grades should overlap 10–30%. This allows a senior person at the top of one grade to be paid more than a junior person at the bottom of the next — realistic and motivating.

Step 3: Decide Where Each Employee Falls in the Range

This is the human part. You have a range. Your employee has a performance rating, tenure, and market value.

A common approach is comp-to-midpoint ratio (compa-ratio):

• 0.80–0.90: New hire or below-expectation performer.
• 0.95–1.05: Fully competent, meets expectations.
• 1.10–1.20: Top performer, high value, at risk of leaving.

Don’t jam everyone at the midpoint. That destroys differentiation. But do be transparent: tell employees what their compa-ratio is and why. It removes the mystery that breeds distrust.

Step 4: Create Salary Increase and Promotion Rules

Now the structure needs to move. You need policies for:

• Merit increases — annual cost-of-living + performance. Typical: 2–5% for meets, 5–8% for exceeds, 0–2% for below.
• Promotions — moving an employee to a higher grade. Common rule: increase salary to at least the new grade’s minimum, but ideally to the midpoint (or 10%+ increase, whichever is higher).
• Equity adjustments — when market data shifts, or you discover an internal inequity. Fix these immediately, not at annual review time.

The dreaded “compression”

When new hires get paid more than existing employees in the same role, you have compression. It’s toxic. Solve it by giving out-of-cycle raises to tenured employees before you make that next hire.

Step 5: Communicate the Structure (Yes, Internally)

Most companies treat salary structure as a secret. That’s a mistake. When employees don’t know how pay works, they assume the worst.

Transparency doesn’t mean publishing everyone’s salary. It means publishing:

• The grade system and its criteria.
• The general pay philosophy (e.g., “We target the 50th percentile for our industry”).
• How performance ties to compa-ratio.

Companies like Buffer and GitLab publish entire salary formulas online. You don’t need to go that far — but sharing the framework builds trust and reduces the “am I getting screwed?” anxiety.

Common Pitfalls (And How to Avoid Them)

1. Using a single market data point

Don’t anchor on one survey. Blend at least three sources or weight a paid survey heavily but cross-check with free data.

2. Ignoring geography

A senior dev in San Francisco costs 40% more than one in Austin. Use geographic differentials — apply multipliers to base ranges by location.

3. Over-indexing on “competitive”

Chasing the 90th percentile for every role bloats your budget. Be competitive for critical roles (engineering, sales leadership), but aim for median in less competitive functions (admin, support).

4. Letting managers override the system

If a manager negotiates a new hire to 30% above midpoint, that hire will be inequitable from day one. Build in enforcement: HR or finance must approve exceptions.

5. Treating bonus and equity as an afterthought

Total compensation = base + bonus + equity + benefits. A robust structure includes target bonus percentages (e.g., Senior IC: 10%, Director: 25%) and equity grant guidelines tied to level.

Keeping the Structure Alive

A compensation structure isn’t a once-a-year project. It’s a living system.

• Quarterly: Refresh market data for high-turnover roles. Adjust ranges if needed.
• Annually: Conduct a full comp review cycle (merit, promotions, equity adjustments).
• Ongoing: Monitor for compression, pay equity gaps (gender, race), and retention risk signals.

And don’t forget: compensation is a tool, not a strategy. It supports culture, but it can’t replace it. Even the cleanest salary structure won’t keep someone who hates their manager or finds their work meaningless.

But a structured, fair, transparent pay system will keep you from being the reason they leave.
