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:

Percentage*WeightedAverage*=Total Percentage(*Grade*1×100*Percentage*1)+(*Grade*2×100*Percentage*2)+…+(*Graden*×100*Percentagen*)

How to Use:

- Enter your grades in the ‘Grades’ input, separating them with commas.
- Enter the corresponding percentages for each grade in the ‘Percentages’ input, separating them with commas.
- 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:

**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.**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.**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.**Q:**Is the result always displayed with two decimal places?**A:**Yes, the calculator presents the result with two decimal places for accuracy.**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.
