Purpose and steps
Assignment Grade Calculator validates method, rows: earned, possible [weight % for weighted mode] before applying the displayed equation. Two-column rows are for total-points mode; weighted rows require three columns.
- Combine assignment scores using total earned points divided by total possible points or explicit normalized weights. Each possible-point total must be positive.
- Enter Method, Rows: earned, possible [weight % for weighted mode] 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. Two-column rows are for total-points mode; weighted rows require three columns. Extra-credit points above the stated possible total are not accepted in this version.
Input reference and units
These values reproduce the model’s demonstration. Replace them with your own records or measurements; they are not recommended targets.
On a small screen, swipe the table horizontally to see all columns.
| Parameter | Demonstration value | How to enter it |
|---|---|---|
| Method | Total points | Select the explicitly labeled convention before interpreting the numerical input. |
| Rows: earned, possible [weight % for weighted mode] | 18 20 45 50 | Two columns per line: points earned, maximum points. Do not include a header. |
Model-specific method
How this calculator produces its result
Assignment Grade Calculator: points grade = Σearned / Σpossible × 100; weighted grade = Σ(earned/possible × weight) / Σweight × 100. Input definitions: mode = Method; rows = Rows: earned, possible [weight % for weighted mode]. Use the selected convention throughout the calculation.
Assignment Grade Calculator: calculation relationships
Combine assignment scores using total earned points divided by total possible points or explicit normalized weights. Each possible-point total must be positive. Two-column rows are for total-points mode; weighted rows require three columns. Extra-credit points above the stated possible total are not accepted in this version.
Weighted rows contain earned points, possible points and a weight. A 9/10 assignment weighted 20 and a 35/50 assignment weighted 80 give 90×0.2 + 70×0.8 = 74%. In total-points mode the same scores give 44/60 instead. Switching methods changes the denominator and the required number of columns; neither method is universally the school’s rule.
points grade = Σearned / Σpossible × 100; weighted grade = Σ(earned/possible × weight) / Σweight × 100
- mode: Method. Select the explicitly labeled convention before interpreting the numerical input.
- rows: Rows: earned, possible [weight % for weighted mode]. Two columns per line: points earned, maximum points. Do not include a header.
- Result units: stated beside each output
- Calculation relationship: points grade = Σearned / Σpossible × 100; weighted grade = Σ(earned/possible × weight) / Σweight × 100

Worked example
Assignment Grade Calculator baseline input: Method: Total points; Rows: earned, possible [weight % for weighted mode]: 18 20 / 45 50. Output: Grade = 90 %; Points earned = 63; Points possible = 70. Substitute these values into the displayed equation to reproduce the result.
Reproduce the default scenario
This reproduces the default inputs in the reference table above; it is not an additional independent example. Displayed rounding may differ from intermediate precision.
- Grade
- 90%
- Points earned
- 63
- Points possible
- 70
Reading results without overstating them
- 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.
Assumptions and exclusions
- Two-column rows are for total-points mode; weighted rows require three columns.
- Extra-credit points above the stated possible total are not accepted in this version.
