What is the formula for the Grade Calculator?
Grade Calculator: grade = Σearned / Σpossible × 100. Input definitions: rows = Rows: earned, possible. Use the selected convention throughout the calculation.
Grades & GPA
Grade Calculator
Combine test scores using total earned points divided by total possible points. Larger possible-point totals carry more weight; every possible-point total must be positive.

Every row has two columns: earned and possible points. Separate percentage weights are not supported.
Calculation notes
Understand the Grade Calculator
Grade Calculator validates rows: earned, possible before applying the displayed equation. Every row has two columns: earned and possible points. Separate percentage weights are not supported.
How can I reproduce the Grade Calculator example?
Grade Calculator baseline input: Rows: earned, possible: 18 20 / 45 50. Output: Grade = 90 %; Points earned = 63; Points possible = 70. Substitute these values into the displayed equation to reproduce the result.
How should I interpret the Grade Calculator result?
- Read grade with its stated unit and convention. The default example and the independent worked scenario use different inputs, so compare the assumptions before comparing the numbers.
- Change one input at a time and use the equation to explain the result; do not mix unit, grade-scale, time-zone or rounding conventions across comparisons.
What limits apply to the Grade Calculator?
- Every row has two columns: earned and possible points. Separate percentage weights are not supported.
- Extra-credit points above the stated possible total are not accepted in this version.

How to use it and the math behind it
Four steps to check your inputs and results
- Combine test scores using total earned points divided by total possible points. Larger possible-point totals carry more weight; every possible-point total must be positive.
- Enter Rows: earned, possible in the stated format. Baseline values are for reproduction.
- Check the output unit and convention: Read grade with its stated unit and convention. The default example and the independent worked scenario use different inputs, so compare the assumptions before comparing the numbers.
- Change one input and compare the result. Every row has two columns: earned and possible points. Separate percentage weights are not supported. Extra-credit points above the stated possible total are not accepted in this version.
Grade Calculator: calculation relationships
Total-point grading weights assessments by their possible points. Scores 8/10 and 12/20 produce 20/30 = 66.666…%, whereas averaging 80% and 60% gives a different 70%. Use this tool when the gradebook adds earned and possible points, not when each assessment has an independent percentage weight.
grade = Σearned / Σpossible × 100
