CGPA Calculator

Calculate cumulative CGPA across all semesters. Enter each semester's GPA and credit hours to get overall CGPA, letter grade, and percentage equivalent.

Cumulative GPA Across Semesters — 10-Point Scale

BrainyCalculators editorial insight — unique to this tool

CGPA = Σ(grade point × credits) ÷ Σ credits across all semesters. Indian IITs use 10-point; US uses 4.0. A 8.5 CGPA on 10-scale ≈ 3.4 on 4.0 for rough comparison but conversion tables vary by institution.

When to use this calculator

Use to compute running CGPA from semester grades. For marks % to GPA conversion, use Percentage to GPA.

What is CGPA (Cumulative GPA)?

CGPA (Cumulative Grade Point Average) is the credit-weighted average of all semester GPAs across your degree programme: CGPA = Σ(GPAᵢ × Creditsᵢ) ÷ Σ(Creditsᵢ). Semesters with more credits pull the cumulative average more than light terms — so strong performance in core-heavy semesters matters disproportionately.

This calculator supports both 4.0 (US/international) and 10.0 (Indian CBCS) scales, shows a semester breakdown table, and converts CGPA to an approximate percentage (×25 on 4.0 scale; ×9.5 on 10.0 scale). Use it for postgraduate eligibility checks, scholarship screening, and transcript self-audits.

To convert a single percentage mark to GPA without semester aggregation, use the Percentage to GPA Converter instead. CGPA is for your full record; percentage-to-GPA is for one score.

CGPA Formula

CGPA = Σ(GPAi × Creditsi) / Σ(Creditsi)

Each semester's GPA is weighted by its credit hours. Semesters with more credits have a proportionally larger impact on your CGPA. Only semesters with both a GPA and credits entered are included in the calculation.

How to Use the CGPA Calculator

  1. 1
    Select Your Grading Scale
    Choose between the 4.0 scale (used in the US and many international universities) or the 10.0 scale (common in India and some other countries).
  2. 2
    Enter Semester Details
    For each completed semester, enter the GPA you earned and the total credit hours for that semester.
  3. 3
    Add More Semesters
    Click "Add Semester" to include additional semesters. You can add as many as needed for your program.
  4. 4
    View Your CGPA
    See your cumulative GPA, total credits earned, equivalent letter grade, and percentage equivalent all at once.

Example Calculation

A student on a 4.0 scale with three completed semesters:

Sem 1: GPA 3.5 × 18 credits = 63.0 grade points
Sem 2: GPA 3.8 × 20 credits = 76.0 grade points
Sem 3: GPA 3.2 × 16 credits = 51.2 grade points
Total grade points = 190.2 | Total credits = 54
CGPA = 190.2 / 54 = 3.52
Percentage = 3.52 × 25 = 88%

How the CGPA Calculator Works

Formula, assumptions, and calculation steps for this education tool.

Methodology

Education calculators convert scores, credits, attendance, or time allocations into academic planning metrics.

Calculation Steps

  1. Enter marks, credits, sessions, or study constraints.
  2. Normalize weights and totals.
  3. Apply the grade, GPA, attendance, or scheduling rule.
  4. Display the result with the threshold or remaining requirement.

Assumptions and Limits

  • School grading policies vary and may use different rounding.
  • Attendance rules should be checked against the official policy.
  • Use results as a planning estimate.

Frequently Asked Questions

CGPA stands for Cumulative Grade Point Average. It is a measure of your overall academic performance across all semesters, calculated as the weighted average of your semester GPAs using credit hours as weights. Unlike a single semester GPA, CGPA reflects your entire academic record.

GPA (Grade Point Average) refers to your performance in a single semester or term, while CGPA is the cumulative average across all semesters. Your CGPA is calculated by weighting each semester's GPA by the number of credits in that semester. A strong CGPA requires consistent performance over your entire program.

Improving CGPA requires consistently high performance in upcoming semesters, as earlier semesters remain fixed. Focus on high-credit courses for maximum impact, retake failed or low-scoring courses if your institution allows grade replacement, and aim for above-average GPA in every semester. The more credits remain, the more opportunity you have to raise your CGPA.

Conversion depends on your grading scale. For the 4.0 scale: Percentage = CGPA × 25. For the 10.0 scale (used in India): Percentage = CGPA × 9.5. These are standard conversion formulas, though some universities may use their own conversion tables. Always check your institution's official conversion guidelines.

Real-World Applications

🎓
Postgraduate Admissions
Graduate school applications in North America and Europe routinely require a minimum CGPA (often 3.0/4.0 for master's programmes; 3.5+ for competitive PhDs) — this calculator helps students assess eligibility before applying.
💼
Graduate Job Applications
Employers in consulting, finance, and technology often screen candidates by CGPA, setting minimum thresholds (typically 3.5/4.0 or first-class equivalent). Students track their cumulative average to stay above these filters.
🏆
Academic Honours Classification
Universities use CGPA to award honours distinctions: summa cum laude (top 5%), magna cum laude (top 15%), and cum laude (top 35%) in the US, or First/Second class/Third in UK and Indian systems.
🌍
International Study Credit Transfer
Students transferring between institutions or countries need their CGPA converted between different scales. A 3.5/4.0 CGPA maps to approximately 87.5% on the 4.0 scale — this calculator makes the conversion explicit.
🏦
Scholarship Eligibility
Merit-based scholarships specify minimum CGPA thresholds for initial eligibility and ongoing renewal. Students use CGPA tracking to verify they remain above scholarship requirements each semester.
📋
Academic Probation Monitoring
Universities place students on academic probation if their CGPA falls below a minimum (typically 2.0/4.0). Students and advisers use CGPA calculators to project the future average needed to exit probation.

Common Mistakes

1
Averaging Semester GPAs Without Weighting by Credits
Adding up semester GPAs and dividing by the number of semesters gives a simple average — not a CGPA. The correct calculation is a weighted average: each semester GPA must be multiplied by its credit hours. A heavy-credit semester (24 hours) counts more than a light one (12 hours).
2
Using Percentage Marks Instead of Grade Points
Percentage scores (e.g., 85%) are not the same as GPA grade points (e.g., 4.0). You must first convert percentage marks to grade points using your institution's conversion table before computing the CGPA.
3
Forgetting Incomplete or Failed Courses
Courses with a grade of F or Incomplete typically count as 0 grade points in the CGPA calculation but still contribute credit hours. Omitting them inflates the CGPA. Always include all attempted courses unless your institution uses grade forgiveness/replacement policies.
4
Applying the Wrong Scale to Your Institution
Grading scales vary — a 3.0 on a 4.0 scale does not equal a 7.5 on a 10.0 scale (it equals approximately 75% via the standard formula). Applying the wrong scale when converting or comparing CGPAs produces meaningless results.
5
Expecting Rapid CGPA Recovery in One Semester
CGPA is cumulative by definition. After 4 semesters of average performance, one excellent semester can only move the CGPA modestly. The more total credits completed, the smaller the impact of any single future semester — setting realistic expectations is important for academic planning.
