Compa-Ratio Calculator

Compa-ratio shows where a salary sits relative to the midpoint of its pay range. It is the standard measure compensation professionals use to decide whether a salary is competitive, lagging, or already stretched. Every number on this page is calculated in your browser and never leaves your device.

IndividualGroup

Use base salary only. Compa-ratio is calculated on base pay, because that is what salary ranges and merit decisions govern.

The midpoint is your target market rate for a fully proficient employee in this role.

Watch this move

A compa-ratio shifts every time you adjust a salary or rebuild a range, so it is worth recording each cycle. The HRAnalyst™ Workbook is a printable tracker for every calculator on this site, with the formula, the recommended cadence and space for four quarters. Join the list and we will send it, along with new calculators and workforce analytics as they publish.

How to read a compa-ratio

Compa-ratio

Band

What it usually indicates

Below 0.80

Below the common working band

Often a new hire, a recent promotion, or a range that has moved. Worth review.

0.80 to 0.89

Low in band

Typical for employees still building proficiency in the role.

0.90 to 1.10

Target zone

The expected position for a fully proficient employee.

1.11 to 1.20

High in band

Typical for sustained strong performers and long tenure.

Above 1.20

Above the common working band

Limited room remaining. Often signals a promotion conversation or a structure that needs updating.

Interpretation bands reflect common practice as described by WorldatWork, the association of compensation professionals. They are professional convention rather than a legal or universal standard, and they vary by industry and pay philosophy.

Start with a midpoint you trust

A compa-ratio is only as good as the midpoint you feed it, and HRAnalyst does not supply one.

Two ways to get one

What It Pays™ has government verified wage data by role and state, so you can look up a single job and bring the midpoint back here. Organizations that need midpoints across a whole employee population rather than one job at a time can get them through an employer account.

Formula used

How do you calculate compa-ratio?

Compa-ratio = salary / range midpoint

Group compa-ratio = sum of all salaries / sum of all range midpoints

A group compa-ratio is not the average of individual compa-ratios, and it is not average salary divided by a single midpoint, because employees in a group frequently sit in different grades. Summing both sides is what makes the group figure comparable.

Common mistakes with compa-ratio

Treating the midpoint as an average of current salaries.

The midpoint is a market target, not a description of what your people currently earn. Building the midpoint from your own payroll turns compa-ratio into a measurement of itself.

Comparing compa-ratios across different range spreads.

Two employees can both sit at 0.95 while occupying very different positions in their ranges, because a wide range and a narrow range place the same ratio in different places. Range penetration answers that question.

Reading a low ratio as a performance problem.

A compa-ratio below 0.90 often reflects tenure, a recent hire, or a range that has moved rather than anything about the employee.
