How do I calculate my weighted grade?
Multiply each normalized grade by its weight, add those results, and divide by the total entered weight. The calculator performs this automatically for percentages, points, numeric scales, and configured letter grades.
Do weights need to add up to 100%?
No. If your entered components total less or more than 100%, the calculator divides by the total weight you entered. It does not treat unentered coursework as a zero.
How do I calculate what I need on my final?
Enter your current grade, the final-exam weight, and the desired overall grade. The calculator solves for the final grade required to reach that target.
Can I use a 0โ20 grading scale?
Yes. Select the 0โ20 numeric scale. For example, 16.4 / 20 is normalized to 82% for the calculation and results remain displayed on the 0โ20 scale.
Can I use a 1โ5 or 1โ10 grading scale?
Yes. Select the numeric scale that matches your class. The included 1โ6 preset explicitly treats lower numbers as better; use the custom numeric scale when your institution uses another range or direction.
Can I enter points instead of percentages?
Yes. Select Points / score with maximum and enter each achieved score, its maximum score, and its weight. Each row is normalized as achieved points divided by maximum points.
How are letter grades calculated?
The AโF option uses configured normalized values and grade-band thresholds. Continuous results show the normalized score and the matching configured band, because a calculated average does not always fall exactly on a discrete letter grade.
Are grade conversions the same in every country?
No. A grade value or letter does not have one universal international equivalent. Use the selected scale as a calculation model for your class, and check your school's own policy for any official conversion.
What if I need a grade above the maximum?
The calculator does not silently cap the result. It shows the mathematical grade required and flags that it exceeds the selected scale's standard maximum.
Can grading systems differ between schools?
Yes. Boundaries, rounding, weighting, and even whether lower or higher numbers are better can differ by course or institution. Use the custom scale when an included preset does not match your rules.
