Employee KPIs: how to set them, measure them and keep motivation intact

A KPI (key performance indicator) is a numeric measure that shows how well a role, team or process is delivering the result it exists for. Achievement on a single KPI is calculated as actual ÷ target × 100%. An employee's overall score is the sum of their achievement on every KPI, multiplied by each KPI's weight.

A working set is three to five KPIs per role, each with its own data source. If there are more than seven, or if even one of them is calculated by hand on gut feel, the system will not survive a single quarter.

What a KPI is and what it is not

Three terms get mixed up all the time, and that confusion is where broken KPI systems come from.

• Metric: any number you can measure, such as calls, visits or requests.
• KPI: a metric that reflects the outcome of the role and that the person can genuinely influence.
• Target: the number to reach within the period.

The number of calls is an activity metric. The conversion rate from call to meeting is a KPI, because it shows the quality of the work rather than the amount of movement.

Types of KPIs

A practical rule: every set needs at least one leading indicator. If all your KPIs are lagging, managers learn about a problem only when it is too late to change anything.

How to set KPIs step by step

Step 1. Define the outcome of the role

Not a list of duties, but an answer to the question: what is the company paying this role for? For a recruiter, it is not “interviews held” but “vacancies filled with people who passed probation”. If the outcome of the role is not defined, the KPIs will end up measuring activity.

Step 2. Choose 3 to 5 KPIs

Each KPI must pass a control test: can this person move the number through their own actions? Company-wide profit in a warehouse supervisor's KPIs is a classic example of a measure that only demotivates.

The second filter is SMART: the KPI is specific, measurable, achievable, tied to the outcome of the role and time-bound. If it fails any of these criteria, fix it before it is approved.

Step 3. Set a baseline and a target

The baseline is actual performance over the last three to six months, not what the manager would like to see. The target is set from the baseline, not from the ceiling. A target that is impossible from day one works exactly like having no target at all.

Step 4. Name the data source

For each KPI, write down which system the number comes from, who pulls it and how often. A KPI without a source is a future argument at the end of the period.

Step 5. Agree it with the employee

The employee needs to understand how each number is calculated and what they can do to move it. A KPI that someone first discovers on their payslip does not change behaviour.

How to calculate KPI achievement

Achievement on one KPI: actual ÷ target × 100%. Overall score: the sum of (achievement × weight). The weights always add up to 100%.

Two technical details that are often missed. First, for KPIs where lower is better (lead times, losses, turnover), the formula is inverted: target ÷ actual × 100%. Second, cap achievement on any single KPI at 120 to 150%, otherwise one unusually large deal will hide poor results everywhere else.

Linking KPIs to bonuses without doing damage

When all pay depends on the numbers, people start optimising the numbers instead of the work: closing tickets without solving them, moving deals between months, picking the easy vacancies. This is not a question of honesty but a predictable reaction to the incentive.

• Keep a fixed component. For most roles, a healthy split is a larger fixed salary with a variable element on top as a reward for results. Fully variable pay only makes sense in classic sales roles.
• Set a threshold. The bonus starts paying out from a certain level of achievement, for example from 80%.
• Cap the upside. A maximum payout at 120 to 150% protects against one-off anomalies.
• Add a quality brake. A volume KPI only works alongside a quality KPI: churn, returns, repeat contacts.
• Do not change the rules mid-period. Adjustments happen at the start of the next cycle, otherwise the system loses trust in one go.

In the UK, if a bonus is contractual, its rules are part of the employment terms, so changing them without agreement can amount to a breach of contract. Keep the KPI and bonus rules in writing, in the contract or a separate bonus policy, and state clearly whether the bonus is contractual or discretionary. In Ukraine, bonus rules are set out in a bonus regulation or collective agreement, and employees must be notified of changes to pay terms at least two months in advance (Article 32 and Article 103 of the Labour Code); under martial law, notice can be given no later than the day the new terms take effect (Article 3 of Law No. 2136).

KPIs work best for stable processes. When the goal is change, OKRs tend to work better. The differences between the two approaches are covered in OKRs vs. KPIs: choosing the right framework.

Common mistakes

KPI matrix template

The “data source” column matters more than all the others. It is the reason the matrix survives past month three.

Where to keep KPIs between periods

A spreadsheet matrix works right up until the team grows past twenty people. In the Perform module, KPIs are set up as their own records: individual, or for a department, location, division or the whole company. Each one has a metric in percent, number or currency, an owner, a weight and a target for every month. Results are entered by hand, imported from a file or sent from other systems via API, and a status shows whether the KPI is on track, behind or at risk.

Goals for each cycle sit in the same module and can be added to the review cycle alongside competencies, so the manager sees in one period what the person achieved and how they worked. The KPI report shows the owner and type of each KPI, so you can see whether a target is being missed by one person or by an entire team. The second usually points to a problem with the target, not the people.

Frequently asked questions

What is a KPI in simple terms?

It is a number that shows how well a role or team is delivering its result. Achievement is calculated as actual divided by target, expressed as a percentage.

How many KPIs should one employee have?

Three to five. Fewer than three gives a one-sided picture; more than seven and the person loses focus and the KPIs turn into reporting.

How do you calculate KPI achievement as a percentage?

Divide actual by target and multiply by 100%. For KPIs where lower is better, invert it: target divided by actual. The overall score is the sum of each achievement multiplied by its weight.

What is the difference between KPIs and OKRs?

A KPI monitors a stable process and is expected to hit 100%. An OKR describes a change within a specific cycle, and a healthy score there is 60 to 80%. The full comparison is in OKRs vs. KPIs.

Can you set KPIs for back-office roles?

Yes, but through deadlines, accuracy and error rates rather than revenue. Examples: month-end close time, share of documents processed on time, number of reporting errors.

How often should KPIs be reviewed?

Targets every quarter; the KPI set itself every six months or after a significant change to the process. The rules are not changed within a period.

Can you withhold a bonus if KPIs are missed?

Yes, if the written bonus rules set a threshold below which no bonus is paid. In the UK, a contractual bonus that has been earned under its rules is owed, while a genuinely discretionary bonus still has to be decided rationally and in good faith. In Ukraine, the bonus can be withheld only on the grounds set out in the bonus regulation; base salary does not depend on KPIs in either country.
