Introduction
Determining whether employees are paid fairly relative to your salary ranges sounds straightforward—until you realize that “fair” depends on market conditions, tenure, performance, and your organization’s compensation philosophy. The question “what is a good compa ratio” comes up constantly in merit planning, offer approvals, and pay equity reviews, yet many HR and compensation professionals rely on surface-level rules like “aim for 100%” without understanding what that number actually means in context. This guide explains how to calculate compa ratio, interpret different ranges, and use this compensation metric to support defensible pay decisions backed by real-time data.
This article is written for U.S.-based HR, total rewards, and compensation professionals who are designing pay structures, running merit cycles, or auditing internal pay equity—not for individual employees researching their own salaries. Whether you’re building ranges from scratch or troubleshooting why certain job families consistently fall below midpoint, understanding what makes a compa ratio “good” (or problematic) is essential for maintaining competitive compensation and reducing turnover risk.
A good compa ratio generally falls between 0.8 and 1.2 (80%–120%), with 1.0 (100%) representing alignment with your salary range midpoint. However, what counts as “good” varies by role, tenure, performance level, and market conditions—a 90% ratio might be perfectly healthy for a new hire while signaling underpayment for a tenured high performer.

Understanding Compa Ratio
Compa ratio—short for comparison ratio or comparative ratio—measures how an employee’s salary compares to the midpoint of a defined pay range. The calculation is simple: divide the employee’s base salary by the salary range midpoint. But you cannot determine what is a good compa ratio until you understand what the metric actually captures, what it excludes, and how different types of compa ratios serve different analytical purposes.
This section focuses on base salary compa ratios for exempt and salaried roles in the U.S. context, which is the most common application for compensation professionals building and maintaining pay structures.
What a Compa Ratio Measures (and What It Doesn’t)
A compa ratio compares an individual employee’s base pay—or a group’s aggregated pay—to a reference point, typically the midpoint of an internal salary range built from market data. The midpoint represents what the organization considers the market rate or “fully proficient” rate for a given role within a pay grade.
HR teams commonly express compa ratios in two formats: as a decimal (0.95) or as a percentage (95%). Both represent the same relationship—the employee’s actual salary as a proportion of the salary midpoint. Most HRIS systems and compensation reports use one format consistently, so confirm your organization’s convention before analyzing compa ratios help identify patterns.
Understanding what compa ratio doesn’t measure is equally important. The metric excludes variable pay, bonuses, equity awards, and benefits—it focuses solely on base salary. It also doesn’t capture performance quality, job scope, or whether the underlying pay range is still accurate. A 100% compa ratio against an outdated midpoint may still leave an employee below the current market average.
This distinction matters for interpretation. Before labeling any ratio “good” or “bad,” you need to verify that the midpoint itself reflects current market value and that you’re comparing apples to apples across similar positions.
Types of Compa Ratios You’ll Use
Individual compa ratio compares a single employee’s salary to the midpoint for their role. You’ll use individual ratios during merit planning, promotion decisions, and offer approvals to assess whether a specific person is positioned appropriately within their pay range.
Group compa ratio aggregates salaries and midpoints across a defined population—a team, job family, location, or demographic segment. The formula is: sum of all salaries ÷ sum of all midpoints. This shows whether an entire cohort is generally above or below the organization’s pay policy targets. Group compa ratios are essential for analyze compa ratios by department, gender, or race/ethnicity to identify systemic pay disparities.
Average compa ratio calculates the mean of individual ratios rather than aggregating the raw numbers. This can produce slightly different results than group compa, particularly when salary distributions are skewed. Both metrics have value, but group compa ratio tends to be more common in budget planning, while average compa ratio is useful for understanding typical employee positioning.
Target “good” ranges may differ between individual and group metrics. An organization might accept individual compa ratios between 85%–115% while expecting the group compa ratio for a job family to cluster tightly around 100%. The next section explains how to calculate and interpret these numbers correctly.
How to Calculate and Interpret Compa Ratios
Before deciding what a good compa ratio is, HR teams must calculate it correctly and interpret results in context. A minor error in the formula or an outdated midpoint can make a healthy-looking ratio mask real market risk. This section walks through the compa ratio formula, explains how to choose the right midpoint, and outlines what different ratio ranges typically signal.
The Compa Ratio Formula
The standard compa ratio formula is straightforward:
Compa ratio = Employee’s actual salary ÷ Salary range midpoint
For example, if a software engineer earns $90,000 and the midpoint for that role is $100,000:
$90,000 ÷ $100,000 = 0.90 (or 90%)
This individual compa ratio compares the engineer’s pay to the organization’s defined market rate, showing they are positioned 10% below midpoint.
Some organizations multiply by 100 and store results as percentages in their HRIS; others keep decimals. Either approach works—consistency matters more than format. When reporting to leadership or managers, using percentages (90% vs. 0.90) often improves clarity.
The accuracy of your compa ratio calculations depends entirely on the quality of your midpoint. An outdated or poorly matched midpoint will distort every ratio you calculate, making “good” numbers potentially misleading.
Choosing the Right Midpoint
Compensation professionals typically source midpoints from three places: internal pay ranges derived from market pricing exercises, external market midpoints from traditional salary surveys, or real-time benchmarks from modern tools like SalaryCube’s Bigfoot Live.
The risk with traditional salary surveys is timing. Survey data often reflects compensation figures from 12–18 months ago. Using 2023 data in late 2025 means your apparently “good” compa ratios may actually represent below-market pay, especially in volatile job markets like technology, nursing, or skilled trades where the median salary can shift significantly year-over-year.
Aligning midpoint selection with your compensation philosophy matters. If your pay policy targets the 50th percentile of the U.S. market, your midpoint should reflect that benchmark. If you intentionally lead the market at the 60th or 75th percentile, your midpoint will be higher—and a 100% compa ratio already represents above-average market rate.
Once your midpoints are accurate and aligned with policy, you can establish what counts as a healthy compa ratio range for your organization.
Reading the Numbers: Below, At, and Above Midpoint
Below 100% (<1.0): The employee’s pay is below the salary midpoint. This often applies to new hires still ramping up, employees early in their tenure, or those developing toward full proficiency. A ratio in the 80%–95% range is frequently intentional for these populations—it leaves room for pay raises as employees grow into their roles.
At or near 100% (≈1.0): The employee’s pay equals or closely matches the midpoint, indicating alignment with the organization’s target market position. For fully proficient performers meeting expectations, clustering around 100% suggests the pay structure is working as designed.
Above 100% (>1.0): The employee’s pay exceeds the midpoint. This may reflect high performance, specialized skills, long tenure, or a role the organization intentionally pays above market average to remain competitive. Ratios in the 105%–120% range can be entirely appropriate—but sustained ratios above 120% warrant investigation.
Rough interpretation bands for reference:
-
80%–90%: Typically new hires, early tenure, or developing performers
-
90%–110%: Fully proficient performers aligned with policy
-
110%–120%+: High performers, critical skills, or retention-focused premiums
Whether any specific value is “good” depends on your compensation strategy, the employee’s circumstances, and current market conditions—which the next section addresses directly.
What Is a Good Compa Ratio?
A good compa ratio is one that aligns with your organization’s pay philosophy while reflecting the employee’s role, tenure, and performance level. There is no single “correct” number—instead, compensation professionals work within defined ranges that allow for appropriate differentiation. This section establishes general guidelines, explains how “good” varies by employee segment, and shows how pay philosophy shapes target ratios.
General Guidelines: The 80%–120% Rule of Thumb
Most U.S. organizations treat 0.8–1.2 (80%–120%) as the acceptable compa ratio band, with 1.0 (100%) representing ideal alignment to midpoint. This range accommodates legitimate variation due to hire timing, experience levels, performance differences, and market fluctuations.
When the majority of employees in a job family fall between 90%–110%, the pay structure is generally healthy—people are being paid fairly relative to the organization’s market positioning. Significant clustering below 80% signals market risk: employees may be underpaid relative to what competitors offer, increasing turnover likelihood. Clustering above 120% often indicates structural issues: pay compression, outdated ranges, or mis-leveled roles that no longer match actual job content.
For highly competitive or hard-to-hire roles—senior software engineers, specialized nurses, data scientists—intentionally higher compa ratios (105%–115%+) may be necessary to attract and retain talent. In these cases, a compa ratio above 100% represents a deliberate compensation decision, not a problem to solve.
The key principle: “good” is a range, not a single number. Expecting every employee to sit at exactly 100% ignores career stages, performance differences, and strategic pay positioning.
Good Compa Ratios by Employee Segment
Target compa ratio bands often differ based on where employees are in their career progression and how they perform:
New hires and early-tenure employees (80%–95%): Organizations commonly bring new hires in at the lower end of the pay range, providing room for growth. An HR Business Partner in their first year earning $72,000 against an $80,000 midpoint (90% compa ratio) is typically positioned appropriately—there’s headroom for merit increases as they develop.
Fully proficient performers (95%–105%): Employees who consistently meet expectations and demonstrate the skills expected for their level should cluster around the midpoint. A 100% compa ratio confirms they are paid at market and aligned with the organization’s compensation strategy.
High performers and scarce-skill talent (105%–120%+): Top contributors, employees with hard-to-replace expertise, or those in roles critical to business outcomes may warrant positioning above midpoint. A 115% compa ratio for a high-performing senior engineer in a competitive market can be entirely justified—and “good”—if documented and intentional.
This segmentation connects directly to performance management and merit planning. During annual increases, compa ratio helps allocate budget: directing larger raises toward high performers with lower ratios while proceeding cautiously with employees already above 110%.
Good Compa Ratios by Pay Philosophy and Market Conditions
Your compensation philosophy directly shapes what “good” looks like. An organization targeting the 60th–75th percentile of market pay might intentionally aim for average compa ratios slightly above 100% of midpoint—their strategy is to lead the market for talent acquisition and retention.
Contrast this with a cost-conscious employer or public sector organization that might consider 90%–100% “good” for most roles, with fewer employees positioned above midpoint. Both approaches can be valid—the difference is intentionality and documentation.
Current market conditions also matter. In hot labor markets—tech hubs, healthcare, or regions with low unemployment—even “good” compa ratios may need to trend higher to remain competitive. Using real-time compensation data rather than lagged survey information helps ensure your definition of “good” reflects actual market value, not last year’s averages.
A good compa ratio is ultimately policy-driven and context-dependent. The next section addresses what happens when ratios clearly fall outside healthy ranges.
When a Compa Ratio Becomes a Red Flag
While 80%–120% serves as a rough healthy band, specific situations signal problems requiring investigation. Outliers—whether individual or systemic—should trigger review, not automatic salary adjustments. Understanding why a ratio falls outside normal ranges is essential before taking action.
Low Compa Ratios (<80%): Underpayment and Market Risk
Compa ratios significantly below 80% typically indicate one of several issues: pay ranges built on outdated market benchmarks, aggressive low starting offers that were never corrected, inconsistent promotion practices that failed to adjust pay appropriately, or rapid market movement that left internal ranges behind.
The risks are concrete. Employees paid substantially below market rate are more likely to leave, particularly tenured employees with institutional knowledge. Low compa ratios also create pay equity exposure—if certain demographics consistently cluster at lower ratios, the organization faces legal and reputational risk. Engagement survey data often correlates employee satisfaction with perceived fair compensation.
Before labeling a low ratio as a problem, verify: Is the pay range current? What is the employee’s tenure and performance history? Are there location differentials or other contextual factors? A new hire at 82% compa may be exactly where they should be; a five-year high performer at 78% signals a failure in pay progression.
High Compa Ratios (>120%): Compression and Structural Issues
Sustained compa ratios above 120% can signal pay compression—when individual contributors earn as much as or more than their managers—or mis-leveled roles where job content has evolved beyond the original pay grade. It may also indicate one-off exceptions made for retention that were never governed.
The budget and governance implications are significant. Employees at 125%+ compa ratio have limited room for future base salary increases without exceeding range maximums. This creates pressure at promotion time and can undermine internal equity when peers in the same position earn substantially less.
When you encounter high ratios, confirm the job match is accurate—the employee may be performing work that belongs in a higher grade. Evaluate whether the range itself needs resetting using updated market data. SalaryCube’s real-time benchmarking can help determine if high ratios reflect outdated ranges rather than overpayment.
Problematic Patterns at the Group Level
Group-level red flags often matter more than individual outliers. Systematically lower compa ratios in certain locations, job levels, or demographic groups versus peers in comparable roles suggest structural inequities in hiring, promotion, or pay practices.
Wide compa ratio distributions within a single job family—some employees at 85%, others at 118% with similar tenure and performance—indicate inconsistent manager practices. This variability undermines compensation philosophy and creates internal equity concerns when employees compare notes.
Using dashboards or analytics tools to review compa ratios by department, gender, race/ethnicity, and tenure helps surface these patterns before they become compliance issues. DataDive Pro reporting enables this analysis at scale, flagging anomalies that manual spreadsheet reviews might miss.
Identifying red flags is the first step—the next section explains how to use compa ratio data proactively in everyday compensation decisions.
Using Compa Ratios to Guide Pay Decisions
Once you understand what a good compa ratio looks like for your organization, the next step is embedding this compensation metric into everyday decisions: range design, offers, merit cycles, and equity reviews. Compa ratio works best as one input among several, not as an automatic decision rule.
Setting Compa Ratio Targets in Your Pay Structure
Translating compensation philosophy into numeric targets requires explicit documentation. If your policy is to pay employees at the 50th percentile of the U.S. market, your target compa ratio for fully proficient performers should cluster around 100%. If you lead market by 10%, your midpoints should reflect that premium, making 100% compa already above average market rate.
Create documented bands by grade and job family—for example, “Target range for Grade 10: 90%–110%, with exceptions above 115% requiring VP approval.” This governance prevents ad hoc decisions that create pay disparities over time.
Modern tools like SalaryCube’s salary benchmarking enable annual or semi-annual range refreshes so targets stay aligned with current market conditions rather than drifting as the labor market evolves.
Merit Increases and Promotion Decisions Using Compa Ratios
Compa ratio serves as a valuable input during annual increase planning when used alongside performance data and role criticality. A structured approach:
-
Segment employees by current compa ratio: Group employees into bands—below 90%, 90%–110%, above 110%—to understand distribution.
-
Overlay performance ratings and role criticality: A high performer at 85% compa warrants different treatment than an average performer at 112%.
-
Direct budget strategically: Allocate larger increases to high performers with low-to-mid compa ratios. Proceed cautiously with employees already above 110%—consider non-base rewards or evaluate whether they’re ready for promotion to a higher range.
-
Document rationale for exceptions: Maintain audit trails showing why certain employees received above-guideline increases. This supports pay equity reviews and demonstrates that compensation decisions follow defensible logic.
Compa ratios should never auto-drive raises. Recent promotions, location changes, market adjustments, and individual circumstances still require judgment.
Checking Pay Equity and Compliance with Compa Ratios
Group and average compa ratios segmented by protected classes—gender, race/ethnicity, age—can flag potential inequities before formal legal reviews surface problems. If male managers average 103% compa while female managers average 94% with similar tenure and performance, that gap demands investigation.
Compa ratios are a starting point, not a complete analysis. Deeper regression modeling or controlled pay equity studies may be needed for compliance with pay equity laws in states like California, New York, or Colorado. But compa ratio analysis often reveals patterns that prioritize where to focus those more intensive reviews.
Real-time market checks through tools like Bigfoot Live help ensure identified gaps are real disparities rather than artifacts of stale midpoints. If your ranges haven’t been updated in 18 months, apparent equity issues may actually be market alignment issues—or vice versa.
Common Challenges and How to Address Them
Compa ratios are simple in concept but frequently generate confusion among managers and executives. Misunderstanding what is a good compa ratio, overreliance on a single number, or communication gaps can undermine even well-designed compensation practices.
Challenge 1: Treating 100% as the Only “Good” Number
Many managers assume every employee must be at exactly 100% to be paid fairly. This belief ignores legitimate reasons for variation—new hires ramping up, high performers earning premiums, or tenured employees who’ve progressed through the range.
Solution: Educate leaders on healthy ranges by segment. Provide visual banding charts showing that 85%–90% is appropriate for employees in their first year, while 105%–115% may be justified for top performers. Update compensation policy documentation to explicitly define good compa ratio range expectations by tenure and performance level.
Challenge 2: Using Outdated or Misaligned Ranges
Ranges built on 18-month-old survey data can make apparently healthy compa ratios—95%, 100%—still represent below-market pay. The employee looks appropriately positioned, but they’re actually underpaid relative to what competitors currently offer.
Solution: Schedule periodic range refreshes using real-time U.S. salary data. SalaryCube’s daily-updated benchmarks eliminate the survey-cycle lag that distorts compa ratio calculations. Document your update cadence—quarterly, semi-annually, or annually—and stick to it. When market conditions shift rapidly, consider off-cycle adjustments for critical roles.
Challenge 3: Poor Communication with Managers and Employees
Even well-designed compa ratio policies fail if HR cannot clearly explain what the numbers mean and how they’re used. Managers who don’t understand the compensation process may make promises to employees that conflict with policy, creating frustration and mistrust.
Solution: Develop manager training on compa ratios during annual merit cycle preparation. Create short internal FAQs and one-page explainers that define terms, show sample ranges, and explain why an employee at 92% isn’t being “underpaid.” Avoid giving individual employees their specific compa ratios unless your organization has decided to embrace full pay transparency—focus instead on explaining range positioning and growth paths.
Clarity around what constitutes a good compa ratio builds trust across the organization and speeds compensation decisions at every level.
Conclusion and Next Steps
A good compa ratio generally falls between 80%–120%, with 100% representing alignment to your salary range midpoint. But “good” isn’t a fixed number—it depends on your compensation philosophy, the employee’s tenure and performance, the role’s market position, and whether your underlying midpoints reflect current market value rather than outdated survey data.
HR and compensation professionals who treat compa ratio as a diagnostic rather than a decision rule—and who pair it with accurate, real-time market data—can use this metric to maintain internal equity, remain competitive for talent, and make defensible pay decisions.
Practical next steps:
-
Audit your current compa ratio distribution by job family, grade, and demographics to identify outliers and patterns
-
Define explicit target ranges by level and performance tier, documenting expectations in your compensation policy
-
Refresh midpoints using real-time U.S. salary data to ensure your “good” ratios reflect today’s market, not last year’s
-
Create manager-facing guidance explaining healthy ranges and how compa ratio informs—but doesn’t dictate—merit decisions
Adjacent topics worth exploring include range penetration (for understanding career progression within bands), pay equity analysis (for compliance and fairness audits), and job leveling (to ensure roles are matched correctly before calculating ratios). Each complements compa ratio work and strengthens overall compensation program design.
