What it means
An appraisal combines an assessment of what was achieved, such as targets hit and projects delivered, with how it was achieved, such as quality of work and collaboration with others. The output is usually a rating on a scale, supported by written commentary and a set of objectives for the coming period.
Most organisations run the process annually, often with a lighter mid-year review. It matters financially because it is the mechanism connecting the payroll line, frequently the largest cost in a service business, to actual output.
Without it, salary increases drift towards uniform annual rises regardless of contribution, and the strongest performers quietly move to employers who notice the difference. Most systems score employees against weighted criteria and roll the result into an overall rating.
That rating then maps to a merit increase percentage and often to a bonus multiplier, which is how a qualitative conversation becomes a number in the payroll system. In practice the mechanics matter less than the calibration.
Managers rate differently, so most organisations run a moderation session in which ratings across teams are compared and adjusted before anything is communicated. Without that step, generous managers effectively buy their teams larger pay rises than colleagues doing equivalent work.
The most common variant is the continuous check-in model, where short documented conversations happen monthly or quarterly and the annual appraisal simply summarises them. The nuance to keep in view is that appraisal is a spending control as well as a people process, since finance teams model the total merit budget before ratings are finalised.
In practice
Real-world examples.
Example
A hospital trust reviews 300 nursing staff annually against clinical standards, patient feedback and mandatory training completion. Ratings feed directly into progression through a published pay band rather than into discretionary rises.
Example
A software company replaces annual ratings with quarterly check-ins after exit interviews reveal that engineers found once-a-year feedback useless. The annual appraisal remains, but only as a summary used to set the merit increase.
Example
A field sales team is appraised on a scorecard that weights new revenue at 50%, customer retention at 30% and forecast accuracy at 20%. The forecast accuracy component is added specifically to stop representatives inflating their pipelines.
Formula
Calculation
Weighted appraisal score = Sum of (Criterion rating x Criterion weight)
An account director is assessed on four criteria, each rated from 1 to 5. The criteria carry different weights because they are not equally important to the role.
Revenue delivery: weight 40%, rating 4, contribution = 0.40 x 4 = 1.60
Work quality: weight 25%, rating 3, contribution = 0.25 x 3 = 0.75
Collaboration: weight 20%, rating 5, contribution = 0.20 x 5 = 1.00
Development of others: weight 15%, rating 4, contribution = 0.15 x 4 = 0.60
Weighted score = 1.60 + 0.75 + 1.00 + 0.60 = 3.95 out of 5
The company's merit matrix awards a 4% increase for scores between 3.50 and 4.24. The account director's current base salary is $80,000.
Merit increase = $80,000 x 0.04 = $3,200
New base salary = $80,000 + $3,200 = $83,200
If forty employees averaged the same 4% outcome on a total base payroll of $3,200,000, the merit budget required would be $128,000, which is the figure finance needs to approve before ratings are released.Case study
Seen in the real world.
The following is an illustrative, fictional example. Aldergate Professional Services employed 220 consultants and found that 84% of them were rated in the top two categories of a five-point scale. The merit budget was consistently overspent, and high performers complained that the ratings meant nothing.
The fictional firm introduced calibration panels in which each department head presented their proposed ratings alongside comparable roles from other teams. It also published examples of what each rating level looked like in practice, so managers had a shared reference rather than a personal one.
In the first year after the change, the proportion rated in the top two categories fell to 41% and the merit budget came in on plan. More usefully, voluntary attrition among the highest-rated consultants dropped, because the pay difference between an outstanding year and an adequate one had become visible for the first time.
Watch out
Common mistakes.
- Judging a whole year on the last two months of work, a recency bias that systematically disadvantages people who delivered early in the period.
- Skipping calibration, which lets inconsistent rating standards between managers turn into unequal pay outcomes.
- Setting objectives that were never written down, so the appraisal becomes an argument about what the targets actually were.
Questions
People also ask.
How often should appraisals happen?
Formally once a year for pay purposes, but supported by regular shorter conversations so nothing in the annual review is a surprise.
Should appraisal ratings be linked directly to pay?
Usually yes for merit budgets, though many organisations separate the development conversation from the pay conversation by a few weeks.
What is forced distribution?
A system requiring a fixed proportion of employees in each rating band, which controls cost and rating inflation but is widely criticised for damaging teamwork.
