A KPI result does not determine the payout by itself. The plan must specify the relationship between performance and earnings, including any weighting, thresholds or other conditions.
The following examples use an illustrative €10,000 target bonus for a full measurement period. They assume the employee is eligible throughout the period and that no additional adjustments apply.
Simple KPI-based bonus
Under a linear model, the bonus changes in proportion to KPI achievement:
Payout = target bonus × achievement
If the target is €500,000 of eligible revenue and the employee achieves €450,000, achievement is 90%. With a €10,000 target bonus, the payout is €10,000 × 90% = €9,000.
This example assumes proportional payout at that achievement level. A plan with a threshold, stepped payout scale or accelerator would produce a different result.
Weighted KPI-based bonus
Where several KPIs contribute to the bonus, first allocate the target bonus according to their weights. Apply the relevant payout factor to each portion, then add the results.
| KPI |
Weight |
Allocated target bonus |
Payout factor |
Earned bonus |
| Eligible revenue |
60% |
€6,000 |
110% |
€6,600 |
| Customer retention |
40% |
€4,000 |
90% |
€3,600 |
| Total |
100% |
€10,000 |
|
€10,200 |
In this example, each payout factor equals KPI achievement because both components use a linear payout rule. Other plans may translate achievement into payout differently. The weight determines the share of the target bonus assigned to a KPI; the payout rule determines what that share earns.
KPI with a performance gate
A gate makes payment conditional on a separate requirement. For example, a plan could calculate a €9,000 revenue bonus but make it payable only if the relevant sales meet a defined gross margin requirement.
If the requirement is met, the €9,000 is payable under this example. If it is not met, the payout is zero. The plan must define the margin calculation and whether the condition applies to each transaction, one bonus component or the whole bonus.
Gates can create a sharp difference between two otherwise similar results. Use them where the condition serves a clear purpose, and explain the consequences before the performance period begins.
Targets deserve the same attention as the formula. A mathematically clear model can still create an unrealistic earning opportunity if the target does not reflect the territory, customer base or resources available. Our guide to setting KPI benchmarks and targets explores that part of the design.
Before introducing the plan, also test what happens below target, above target and at any payout boundary. Document the treatment of missing data, eligibility changes and corrections so those decisions do not have to be improvised when someone’s pay is being reviewed.
