How to Use the Percentage Calculator
Our tool simplifies finding your overall percentage. Follow these easy steps:
- Choose Calculator Type: Select “Standard” for basic percentage calculation or “Weighted” if your subjects have different credits or weights.
- Enter Marks: For each subject, input the “Marks Scored” and the “Total Marks”. For weighted calculations, also enter the “Weight” (e.g., credits).
- Add More Subjects: Click the “+ Add Another Subject” button if you have more than one assessment to include.
- Calculate: Hit the “Calculate” button to see your overall percentage instantly.
Understanding How Your Overall Percentage is Calculated
Calculating a percentage seems simple, but it gets tricky when subjects have different maximum marks. Simply averaging the individual percentages is incorrect. Our tool uses the aggregate method, which is the correct and universally accepted way to calculate the overall percentage.
The formula is:
Overall % = (Total Scored Marks / Total Maximum Marks) × 100
When to Use the Weighted Percentage Calculator
Some educational systems assign different “weights” or “credits” to subjects based on their importance or difficulty. In such cases, a simple aggregate percentage isn’t accurate. The weighted calculator gives more importance to subjects with higher weights.
The formula for a weighted percentage is:
Weighted % = [ Σ ( (Scoredᵢ / Totalᵢ) × Weightᵢ ) / Σ (Weightᵢ) ] × 100

Frequently Asked Questions (FAQ)
- Q: What is the aggregate percentage method?
- A: It’s a method where you sum up all the marks you scored and divide it by the sum of the maximum marks for all subjects, then multiply by 100. It’s the most accurate method when totals differ.
- Q: How do I calculate my percentage if subjects have different maximum marks?
- A: Use our Standard Percentage Calculator. It’s specifically designed for this scenario using the aggregate method, ensuring you get the correct result.
- Q: Can I use decimals in my marks?
- A: Yes, our calculator supports decimal values for both scored marks and total marks. This is useful for assessments where scores are not whole numbers.
