Compensation Calculators

Compa-ratio, salary range penetration, bonus proration, and batch compa-ratio calculations. Data stays in this page and no upload is used.

Compa-ratio

Formula: salary divided by range midpoint. Reverse calculation returns the salary needed for a target compa-ratio.

Compa-ratio = salary / range midpoint. Salary for target = midpoint * target compa-ratio.
Ready.
Enter salary and midpoint to calculate compa-ratio.

Range penetration

Formula: salary position within the minimum-to-maximum salary range.

Range penetration = (salary - range min) / (range max - range min) * 100%.
Ready.
Enter salary, range minimum, and range maximum.

Bonus proration

Formula: target bonus multiplied by eligible days, period days, and performance factor. Salary-change mode prorates the target by salary segments.

Bonus = target bonus * (eligible days / period days) * performance factor.
Ready.
Enter target bonus, eligible days, period days, and performance factor.

Batch compa-ratio

Paste employee rows with salary and midpoint. The first two numeric values on each row are used as salary and midpoint.

Accepted paste examples: "Name, 60000, 50000" or "60000 50000". No file upload is used.

Ready.
Batch results will appear here.

    About the Compensation Calculators (Compa-Ratio / Range Penetration / Bonus Proration)

    Evaluating internal pay equity and market competitiveness requires precise mathematical benchmarks. Using compensation calculators for metrics like compa-ratio and range penetration provides human resources teams with objective data on how employee salaries align with established pay bands. Compensation analysts rely on these figures to execute fair annual merit increases, avoid salary compression, and manage departmental budgets effectively.

    How it works

    1. Input the employee's current actual base salary.
    2. Enter the midpoint of the company's designated salary band for that specific job grade to calculate the compa-ratio.
    3. Input the absolute minimum and maximum of the salary range to determine range penetration.
    4. Review the percentages to assess where the employee sits relative to the internal market target.

    Frequently asked questions

    What is a standard or healthy compa-ratio?

    A ratio of 1.0 (or 100%) means the employee is paid exactly at the market midpoint. Ratios between 80% and 120% are generally considered the standard acceptable range.

    How does range penetration differ from a compa-ratio?

    Compa-ratio measures pay relative to the midpoint, whereas range penetration calculates how far into the entire pay band (from minimum to maximum) the employee has progressed.

    What does a compa-ratio below 80% indicate?

    A score below 80% often indicates the employee is new to the role, developing skills, or at a high flight risk due to being significantly underpaid compared to the market.

    Can these metrics highlight pay inequity?

    Yes, analyzing these metrics across different demographics, genders, or departments is a primary method HR uses to identify and correct systemic pay disparities.
