Employee Ratings Calculator

Compare a set of review categories

You have scores for skills, cooperation, communication and attendance, each on the same five-point scale. You want one number to help discuss the review, while still seeing the category scores that produced it. This calculator adds the entered points and compares them with the maximum possible points. It does not decide whether someone should receive a raise, bonus or disciplinary action.

A single overall figure can hide important differences. Someone may score highly on communication and need support with attendance, or the reverse. Keep the underlying review evidence and context beside the number. Decide which categories belong in the review before entering scores; adding a category changes the overall result because every category has equal weight.

Enter one score for each category

1. Edit the four starting category names and their scores to match your review. The starting maximum is five points for every category. A zero score is allowed; an empty score needs correction.
2. Use Add category for another measure or Remove to take one out. At least one category must remain. Open Rating scale if your review uses a different common maximum, from one to ten points. Existing scores stay as entered when you change that maximum, so check that none exceeds the new limit.
3. Read the overall percentage first, then the point total, average per category and each category's score. Results update as you edit. Calculate checks the entries and moves focus to the first error. Reset restores the four-category example.

Name each category differently so one measure is not counted twice by accident. The form allows up to 20 categories. Scores and the common maximum can have up to two decimal places. Blank, negative, malformed or above-maximum scores are invalid; they do not quietly become zero.

Example: 18 of 20 possible points

The default review scores Skills 4, Cooperation 5, Communication 4 and Attendance 5, each out of 5. Those four values total 18 points. Four categories with five possible points each provide 20 possible points, so the overall rating is 18 ÷ 20 × 100 = 90%. The average category score is 18 ÷ 4 = 4.5 out of 5.

If the Skills score changes from 4 to 3, the earned total becomes 17 and the overall rating becomes 85%. This is a five-percentage-point change because one point is one-twentieth of the possible total. If you remove a category, both the earned and possible totals change. Compare ratings only when the category set and scale are the same.

How equal weighting works

The calculator adds the entered category scores without rounding each category first. It multiplies the number of categories by the selected common maximum to find possible points, then divides earned points by possible points. The displayed percentage and average use up to two decimal places. Scores are not stars or ranks; the old decorative star display obscured the actual point calculation.

Every category contributes the same maximum number of points. A separate weight such as “skills count for 40%” is not supported. If your organization has a formal weighted review, a score from this page may disagree with that method. Do not imitate weights by repeating category names: duplicated names are rejected, and repeated criteria would change the meaning of the review.

A score of 0 in every category correctly yields 0%. A blank score or invalid maximum instead removes the result and shows a field message after Calculate. This distinction matters when a review is still incomplete. Enter zero only when zero is the actual assessed score, not because you have not gathered evidence yet.

Use the number as a discussion aid

Agree on category definitions, the scoring scale and the review period before comparing employees. Record concrete examples for each rating and give the person a chance to discuss the assessment. Attendance, for example, can reflect approved leave or scheduling conditions that a raw score does not show. A total percentage cannot explain fairness or the circumstances behind it.

The calculator runs in the browser and does not ask for employee names or store a review history in this form. If you need a formal record, keep it in your authorized review system and follow your organization's privacy and retention rules. For staffing budgets, use the Labor Cost Calculator. For hours from work records, use the Timesheet Calculator.
