Percentage & CGPA Calculator 2026

Calculate marks-to-percentage, CGPA to percentage, and SGPA to CGPA aggregate. Supports CBSE, VTU, and custom university formulas. Add multiple subjects or semesters for cumulative calculation.

Enter marks obtained and total marks for each subject. Add more rows as needed.

How Each Tab Works

Marks → %: aggregate percentage across multiple subjects. Add a row for each subject, enter marks obtained and total marks, click Calculate. CGPA → %: single CGPA value converted via your board's formula — CBSE, VTU, direct, or your own custom multiplier. SGPA → CGPA: aggregate CGPA across semesters using credit-weighted averaging.

Common Conversion Formulas

CBSE Class X / XII: Percentage = CGPA × 9.5. So 9.0 CGPA = 85.5%, 8.4 CGPA = 79.8%. VTU (Karnataka): Percentage = CGPA × 7.1 + 11. Anna University: Percentage = (CGPA − 0.5) × 10. Direct method: Percentage = CGPA × 10 (used by some universities). Always confirm the formula on your marks sheet — it's printed at the bottom.

Minimum Percentage for Government Jobs

Eligibility varies by post: SSC CGL and most SSC posts need only a degree (no minimum %). Banking PO (IBPS / SBI) usually requires 60% in graduation. UPSC Civil Services needs only a degree. Teaching jobs (TGT/PGT) require 50% in Master's plus B.Ed. SC/ST/OBC candidates get 5% relaxation. Use the Age Calculator to check age eligibility alongside marks.

Frequently Asked Questions
