Introduction

A compa ratio shows how one person's pay compares to the market pay for their job. It is a simple percent. If your salary is $74,500 and the market reference pay is $80,000, your compa ratio is 93.1%. That means you are paid a bit below the market rate.

This Compa Ratio Calculator turns those numbers into that percent. Pick your country to set the currency. Then choose one of two ways to start. You can enter your pay range (the lowest and highest pay for the job), and the tool finds the midpoint for you. Or you can type in the market reference pay yourself. Last, enter the employee's actual salary and press Calculate.

You will see the compa ratio as a percent, a color gauge that shows if the pay is low, fair, or high, and the range position (where the salary sits between the range minimum and maximum). The tool also shows each step of the math, a chart, and a table with what the number means and what HR might do next.

There is also a reverse calculator. Enter a target compa ratio, like 100%, and the market reference pay. The tool tells you the salary needed to hit that target. This helps with raise plans, job offers, and pay reviews.

How to use our Compa Ratio Calculator

Enter your pay range or market reference pay, plus the employee's salary. The calculator shows the compa ratio as a percent, where it falls on the gauge, the range position, and what HR should do next.

Input Method: Pick "I Know My Pay Range" if you have a salary band with a low and high number. Pick "I Know the Market Reference Pay" if you already have one target pay number.

Country: Choose your country. This sets the money symbol used in every salary field and result.

Range Minimum: Type the lowest salary in the pay range for that job. Use the plus and minus buttons to change it fast.

Range Maximum: Type the highest salary in the pay range. It must be bigger than the minimum.

Market Reference Pay (Midpoint): You do not type this in range mode. The tool works it out for you by adding the min and max, then dividing by two.

Market Reference Pay: In reference mode, type the market rate or band midpoint for the job. This is the number the salary is compared to.

Employee Actual Salary: Type what the employee is paid now, before bonus. Then press Calculate.

Target Compa Ratio (%): In the reverse calculator, type the compa ratio you want, like 100 for market rate.

Market Reference Pay (reverse): Type the market pay for that job. The tool shows the salary you need to hit your target compa ratio.

What Is a Compa Ratio?

A compa ratio (short for "comparative ratio") shows how a person's pay compares to a market reference pay. The market reference pay is the target pay for that job, often the midpoint of a company's salary range for that role. The answer is shown as a percent.

The Compa Ratio Formula

Compa Ratio = (Employee Salary ÷ Market Reference Pay) × 100

Example: If someone earns $74,500 and the reference pay is $80,000, the compa ratio is 93.1%. That means they earn about 93 cents for every dollar the market pays for that job.

What the Numbers Mean

  • Below 80%. Pay is far under market. This is a big risk for losing the worker.
  • 80%–99%. Pay is under market. This is normal for new or still-learning workers.
  • 100%–110%. Pay matches the market. This is the target zone for a fully trained worker.
  • Above 110%. Pay is over market. Often seen with long-time or top performers.

Compa Ratio vs. Range Position

These two numbers are not the same. Compa ratio compares pay to one point, the midpoint. Range position compares pay to the whole salary range, from the lowest to the highest pay for the job. Range position is found this way:

Range Position = (Salary − Range Min) ÷ (Range Max − Range Min) × 100

A worker can be at 93% compa ratio but only in the 36th percentile of their range. Looking at both gives a clearer picture.

Why Compa Ratio Matters

HR teams and managers use compa ratio to keep pay fair and to plan raises. It helps answer questions like: Are we paying this person enough to keep them? Are two workers doing the same job paid the same way? Do we need to fix a pay gap before someone quits? Workers can use it too, to see if their salary lines up with what the job is worth before asking for a raise.

Things to Watch For

A compa ratio is only as good as the reference pay behind it. If the salary benchmark is old, the ratio will look better than it really is. Update market data at least once a year. Also check that the job is matched to the right grade and level. Comparing the wrong jobs gives the wrong answer.

Frequently asked questions

Does a compa ratio include bonus, overtime, or benefits?

No. A compa ratio uses base salary only. Leave out bonus, overtime, commission, shift pay, and benefits.

Market pay data is usually reported as base pay too. Mixing base pay with bonus makes the ratio look higher than it really is. If you want to compare total pay, use a separate total cash benchmark and label it clearly.

How do you work out a compa ratio for an hourly job?

Turn the hourly rate into a yearly number first, then compare it to a yearly market rate.

Yearly pay = hourly rate × hours per week × 52

Example: $22 per hour × 40 hours × 52 = $45,760. If the market reference pay is $48,000, the compa ratio is 45,760 ÷ 48,000 × 100 = 95.3%.

You can also compare hourly to hourly. Just keep both numbers in the same unit.

Where does market reference pay come from?

It comes from salary survey data for the same job, level, industry, and area. Common sources are paid HR survey providers, industry pay reports, government wage data, and job posting pay ranges.

Most companies take that market data and build a pay range around it. The midpoint of that range then becomes the reference pay used in the compa ratio.

Job title alone is not enough. Match by job duties and level, or the number will be wrong.

What is a group compa ratio?

A group compa ratio shows how a whole team, department, or job grade is paid against market.

Group compa ratio = sum of all salaries ÷ sum of all midpoints × 100

Example: three salaries total $240,000 and their midpoints total $250,000. The group compa ratio is 96%.

Do not just average each person's percent. That gives more weight to low-paid jobs and can hide a problem.

Is a compa ratio over 100% bad?

No. A ratio between 100% and 110% is the normal target for someone who is fully trained and doing the job well.

Above 110% is worth a look, but it is often fair. Long service, top performance, rare skills, and hot job markets all push pay up.

The real warning sign is a high ratio with average performance, or pay that sits above the range maximum. That usually means the job is mapped to the wrong grade.

What compa ratio should a new hire start at?

Most new hires start between 80% and 95%. That puts them in the lower part of the range, with room to grow as they learn the job.

Start closer to 100% when the person already has full skills, strong experience, or when the job is hard to fill.

Starting above 100% is risky. It leaves little room for future raises and can upset workers already in the role.

How much of a raise moves a compa ratio to 100%?

First find the salary you need, then subtract current pay.

Target salary = reference pay × (target ratio ÷ 100)

Example: reference pay is $80,000 and the person earns $74,500. To hit 100%, they need $80,000. The raise is $5,500, which is a 7.4% increase.

Big gaps are often closed over two cycles instead of one, so the budget can handle it.

How does compa ratio affect a merit raise?

Many companies use a merit matrix. It mixes performance rating with compa ratio to set the raise percent.

  • Low ratio, strong performance: the biggest raise, to close the gap fast.
  • Low ratio, average performance: a normal or slightly higher raise.
  • High ratio, strong performance: a smaller raise, sometimes a bonus instead.
  • High ratio, weak performance: little or no increase.

This keeps the same raise budget from pushing already high pay even higher.

Why did my compa ratio drop when my pay went up?

Because the market moved faster than your raise. Compa ratio has two parts, and the bottom part changes too.

Example: you earned $76,000 against an $80,000 midpoint, so 95%. You got a 3% raise to $78,280. But the company updated market data and the midpoint rose 6% to $84,800. Your new ratio is 92.3%.

A raise that is smaller than market movement means you lose ground, even though your paycheck grew.

What does it mean if someone is paid above the range maximum?

They are "red circled." Their pay sits over the top of the range for the job, so a normal percent raise is usually stopped.

Common fixes:

  • Freeze base pay and give a one-time lump sum instead.
  • Check if the job should be in a higher grade.
  • Move the person into a bigger role.
  • Wait for the range to rise with the market.

Pay is almost never cut. The range usually catches up over time.

Is compa ratio the same as pay equity?

No. Compa ratio compares one person's pay to the market. Pay equity compares people to each other for similar work.

Compa ratio still helps with equity checks, though. If two workers do the same job at the same level with the same performance, and one sits at 88% while the other sits at 105%, that gap needs a reason. Skills, experience, and results can explain it. If nothing can, it may be a pay equity problem.

What is range spread and what is a normal one?

Range spread is how wide a pay range is from bottom to top.

Range spread = (Max − Min) ÷ Min × 100

Example: a $60,000 to $100,000 range has a spread of 66.7%.

Typical spreads are:

  • Entry and hourly jobs: 30% to 40%
  • Professional jobs: 40% to 50%
  • Manager jobs: 50% to 60%
  • Senior and executive jobs: 60% or more

Wider ranges give more room for pay to grow inside one job.

Can two workers with the same salary have different compa ratios?

Yes. The salary is only half the math. The reference pay is the other half.

Two people both earning $80,000 will have different ratios if their jobs sit in different grades. Against a $75,000 midpoint, the ratio is 106.7%. Against a $95,000 midpoint, the same $80,000 is only 84.2%.

That is why the ratio is useless if a job is matched to the wrong grade.
