  • This calculator assumes every point in the class is worth the same amount.
  • Entered possible points should include only graded work that counts toward the class total.
  • If your class uses weighted categories instead of raw totals, a weighted grade calculator will be more accurate.

About this Points Grade

In a points-based grading system, every assignment adds to a running total. A 100-point exam is naturally worth 10x more than a 10-point quiz. This calculator determines your percentage and letter grade based on the raw totals.

Who this calculator is for

  • Students in points-based classes who want a fast read on their current standing.
  • Teachers and tutors totaling earned versus possible points after quizzes, labs, and exams.
  • Anyone whose syllabus uses raw points instead of weighted categories.

When to use it

  • Calculate your current grade from accumulated points without building a spreadsheet.
  • Model how future assignments or bonus points could move your percentage.
  • Double-check LMS gradebooks when classes use one running points total.

How to use this calculator

  1. Enter Points Earned (sum of all your scores).
  2. Enter Points Possible (sum of all total values).
  3. The result is your Percentage and Letter Grade.

Key assumptions

  • This calculator assumes every point in the class is worth the same amount.
  • Entered possible points should include only graded work that counts toward the class total.
  • If your class uses weighted categories instead of raw totals, a weighted grade calculator will be more accurate.

How this calculator works

Percentage = (Points Earned / Points Possible) × 100.

Inputs explained

Points Earned

The total points you have accumulated so far.

Points Possible

The total value of all assignments that have been graded. Do not include future assignments.

Example scenarios

Mid-Semester

Earned 450. Possible 500. Result: 90% (A-).

Bonus Points

Earned 105. Possible 100. Result: 105% (A+).

Key Features

  • Simple Ratio Calculation
  • Supports Bonus Points
  • Instant Letter Grade

Tips & Best Practices

  • If you receive bonus points, add them to 'Earned' but NOT to 'Possible'.
  • To project your final grade, estimate points for future assignments and add them to both totals.

Frequently Asked Questions

Is points-based grading better than weighted?
It is simpler to understand. However, weighted grading allows professors to make a Final Exam worth 40% even if it only has 100 points.
What if I missed an assignment?
If you received a 0, include the possible points in the total (it hurts your grade). If you were excused (exempt), do not include those points in the possible total.
