Compa-ratio calculator.
Two standard compensation calculations, run on your own numbers. Where a salary sits inside its range, and how far it is from the midpoint.
Enter your own figures — nothing is sent anywhere.
Two numbers every reward team uses.
Compa-ratio divides a salary by the midpoint of its range. A result of 1.00 means the person is paid exactly at midpoint. Below 1.00 is under it, above 1.00 is over it.
Position in range expresses the same salary as a percentage of the distance from the range minimum to its maximum. Two people can share a compa-ratio and sit at different range positions if their ranges have different spreads.
Neither number is a verdict on its own. They tell you where someone sits; the reason they sit there — tenure, performance, scarcity of the skill, or an error nobody has caught — is the conversation that follows.
Worth knowing
These are the arithmetic conventions used across the profession, not a proprietary model. Any reward team would compute them the same way.
What varies between organisations is the structure underneath: how grades are sized, where midpoints are set, and how wide the ranges are. That is the work, and it is where we come in.
The assumptions.
The midpoint is taken as the middle of the range you enter
This calculator sets the midpoint at exactly halfway between your minimum and maximum. Many organisations do build ranges that way. Others set the midpoint independently — usually from a market median — and derive the minimum and maximum from a spread around it. If your structure works that way, enter a minimum and maximum that are symmetrical around your real midpoint, or the compa-ratio here will not match your own reporting.
The interpretation is a common convention, not a rule
The readout describes what compa-ratio bands conventionally signal — below 1.00 as developing in role, around 1.00 as fully competent, above 1.00 as sustained performance or scarce skills. Plenty of organisations set their own bands, and some deliberately run whole populations above or below midpoint for strategic reasons. Treat the sentence as a prompt for a conversation, not a decision.
It says nothing about whether the range itself is right
A salary can sit perfectly at midpoint of a range that is well behind the market. This calculator only measures position within the range you give it. Checking whether the range is correct requires current market data for that job in that market, which is a different exercise.
Currency and periodicity are yours to keep consistent
The tool is unit-agnostic. Enter all three figures in the same currency and on the same basis — all annual, or all monthly — and the ratios hold.
