What Is a Points-Based Grade Calculator?
Many courses use a total points system rather than weighted categories. In this system, every assignment, quiz, and exam is worth a fixed number of points, and your final grade is simply the total points you earned divided by the total points possible. This calculator does that division for you and converts the result into a percentage and a typical US letter grade.
How to Use It
Add up the points you have earned across every graded item and enter that in Total Points Earned. Then add up the maximum points all those items were worth and enter it in Total Points Possible. Click calculate to see your percentage and letter grade. You can also use it to project a target grade by experimenting with future points.
The Formula Explained
The math is straightforward:
$$\text{Grade \%} = \frac{\text{Sum of Points Earned}}{\text{Sum of Points Possible}} \times 100$$
Because every point counts equally, an assignment worth 200 points affects your grade twice as much as one worth 100 points — there are no separate category weights to track.
Worked Example
Suppose over the semester you earned 850 points out of a possible 1000. Your grade is $$(850 \div 1000) \times 100 = 85\%$$ which corresponds to a letter grade of B on a standard scale.
FAQ
How is this different from a weighted grade calculator? A weighted calculator multiplies each category by a percentage weight. The total points system gives weight automatically through point values, so you only need two totals.
What letter grade scale is used? This tool uses a common scale: 90+ = A, 80–89 = B, 70–79 = C, 60–69 = D, below 60 = F. Your school's scale may differ.
Can I include extra credit? Yes. Add extra-credit points to your earned total without increasing the points-possible total to see the boost.
