Introduction: Calculating grades with percentages is a common practice in educational assessments where different components contribute to the final grade. This calculator provides a straightforward way to determine your weighted average by inputting grades and their corresponding percentages.

Formula: To calculate the weighted average, the calculator uses the following formula:

 PercentageWeightedAverage=Total Percentage(Grade1​×100Percentage1​​)+(Grade2​×100Percentage2​​)+…+(Graden​×100Percentagen​​)​

How to Use:

1. Enter your grades in the ‘Grades’ input, separating them with commas.
2. Enter the corresponding percentages for each grade in the ‘Percentages’ input, separating them with commas.
3. Click the ‘Calculate’ button to obtain your weighted average.

Example: Suppose you have grades of 90, 85, 92 with percentages of 30%, 20%, 30%. Enter these values, click ‘Calculate,’ and the result will be your weighted average.

FAQs:

1. Q: How does the calculator handle different percentages for each grade? A: The calculator multiplies each grade by its respective percentage and then sums the results.
2. Q: What if I have more grades than percentages (or vice versa)? A: The calculator alerts you if the number of grades is not equal to the number of percentages, and calculation won’t proceed until they match.
3. Q: Can I use this calculator for any grading scale? A: Yes, the calculator is scale-agnostic as long as numerical grades and percentages are used.
4. Q: Is the result always displayed with two decimal places? A: Yes, the calculator presents the result with two decimal places for accuracy.
5. Q: What if I want to calculate the overall percentage instead of the weighted average? A: In that case, set all percentages to 100%, and the result will be the simple average of the grades.

Conclusion: The Grades with Percentages Calculator is a practical tool for students and educators dealing with weighted assessments. By providing a quick and accurate way to calculate the weighted average, this calculator facilitates the understanding of overall performance in a course with varying grade components.
