Estimate CGPA from marks with tailored methods. Enter semester data, credits, and scale settings easily. Visualize trends, export reports, and compare outcomes with clarity.
Use direct percentage entry or enable weighted semesters. The form becomes three columns on large screens, two on smaller screens, and one on mobile.
This example table shows how different methods and scales can change estimated results.
| Case | Percentage | Scale | Method | Illustrative CGPA |
|---|---|---|---|---|
| Student A | 76% | 10 | Percentage ÷ 9.5 | 8.00 |
| Student B | 84% | 10 | Direct Proportional | 8.40 |
| Student C | 68% | 4 | Direct Proportional | 2.72 |
| Student D | 88% | 5 | Minimum to Maximum Mapping | 4.00 |
| Student E | 81.5% | 7 | Percentage ÷ 11.64 | 7.00* |
*If clamping is enabled, outputs higher than the selected scale are limited to the scale maximum.
CGPA = Percentage ÷ Divisor. This is common where institutions publish a fixed divisor such as 9.5 for a 10-point estimate.
CGPA = (Percentage ÷ Maximum Percentage) × Scale. This maps the percentage directly to the selected CGPA scale.
CGPA = ((Percentage - Minimum) ÷ (Maximum - Minimum)) × Scale. This is useful when a board defines a pass threshold.
No. Universities, boards, and accreditation systems may use different official rules. This calculator supports several common approaches so you can match your institution more closely.
Choose the method published by your institution. If no official rule exists, use divisor or direct proportional conversion only as an academic estimate.
Weighted mode reflects different semester credit loads. A semester with more credits influences the final percentage more than a lighter semester.
Clamping restricts adjusted percentage and CGPA to valid limits. It prevents results from dropping below zero or exceeding the selected maximum scale.
Yes. Select the 4-point scale directly, or convert to another scale and review the equivalent 4-point figure shown in the result section.
Different calculators may assume different scales, divisors, minimum thresholds, or rounding rules. Institutional policy usually determines the correct official output.
Yes. Bonus or moderation changes the input before conversion. Only use it when your institution actually adds grace marks or moderated percentage adjustments.
Yes. After calculation, use the CSV or PDF buttons in the result section to save the summary for records, applications, or advising discussions.
