EDUCATION CALCULATOR

Grade Calculator

Calculate a course grade using total points or weighted categories. Enter one row per assignment or category and see the percentage and supporting totals.

Points mode divides total points earned by total points possible.

Understanding your result

Points mode divides earned by possible points. Weighted mode adds each score contribution and normalizes by entered weight so incomplete courses can show a current grade.

The formula

Points: Σ earned ÷ Σ possible × 100; Weighted: Σ(score × weight) ÷ Σ weights

A score of 90 with a 40% weight contributes 36 course points. Letter grades use an example 90/80/70/60 scale; your syllabus may differ.

Two assignments worth 150 points

Scores of 80/100 and 45/50 total 125 out of 150. The grade is 83.33%, a B on the example scale.

How to use this calculator

  1. Choose points or weighted categories.
  2. Enter each row as two comma-separated numbers.
  3. Calculate and compare with your syllabus.

Points and weights answer different questions

In a points course, a 100-point exam counts twice as much as a 50-point quiz.

In a weighted course, the syllabus assigns explicit importance to categories.

Current grade versus final grade

When weights total under 100%, the normalized result describes completed categories.

Missing work, dropped scores, and extra credit follow the instructor’s policy.

Assumptions & limitations

What this calculation assumes

  • Rows match the chosen method.
  • Weighted values are percentages from 0 to 100.
  • The letter scale is A≥90, B≥80, C≥70, D≥60.

What to keep in mind

  • Institution-specific cutoffs and policies are excluded.
  • A current grade is not a final-grade prediction.
  • Rows are limited to 100.

Common questions

Must weights total 100%?

A final calculation normally does. A lower total yields a normalized current grade.

Why not average percentages?

Different point values or weights should not count equally.

Can I enter decimals?

Yes. Use a period for decimals.
