GPA Calculator — Calculate GPA & CGPA on 4.0, 5.0 & 10 Scale

Grade Point Average (GPA) and Cumulative Grade Point Average (CGPA) are the standard way schools and universities measure academic performance. Whether you are applying for scholarships, transferring to another university, or calculating your final semester standing, knowing your exact GPA matters. This free GPA calculator supports the three most common scales — 4.0 (US/International), 5.0 (Weighted/Honors), and 10.0 CGPA (Pakistan, India, and much of Asia). Enter your courses, credits, and letter grades to get a credit-weighted average instantly. No signup, no data sent to servers — everything calculates in your browser. Unlike simple average calculators, this tool weights every course by its credit hours, which is exactly how registrars and admissions offices compute your real GPA.

How to Use the GPA Calculator

Calculate your credit-weighted GPA in under a minute:

  1. Choose your scale — Click 4.0, 5.0, or 10.0 CGPA buttons above (or leave default).
  2. Enter each course — Type the course name, credit hours, and letter grade. Click "+ Add course" for more rows.
  3. Click Calculate GPA — See your average GPA, total credits, course count, and which scale is active.

Real example (4.0 scale):

  • Calculus I — 3 credits, grade B (3.0 points)
  • English 101 — 3 credits, grade A (4.0 points)
  • Quality points = (3 × 3.0) + (3 × 4.0) = 21
  • Total credits = 6
  • GPA = 21 ÷ 6 = 3.50

Same example on 10.0 CGPA scale:

  • Calculus I — 3 credits, grade B (8 points)
  • English 101 — 3 credits, grade A (10 points)
  • Quality points = (3 × 8) + (3 × 10) = 54
  • CGPA = 54 ÷ 6 = 9.00

All calculations run privately in your browser.

What Is GPA / CGPA and Why It Matters

GPA is a single number that summarizes your graded academic performance as a credit-weighted average. Universities use it for admissions screening, scholarship thresholds, probation decisions, graduation honors, and employer shortlisting. A higher GPA often opens doors to better programs and financial aid.

In Pakistan, India, and much of Asia, the term CGPA on a 10-point scale is more common than the US 4.0 GPA — but the underlying math (credit × grade points ÷ total credits) is exactly the same. The difference is only in how letter grades map to numbers.

Scale Typical Region / Use A Grade B Grade C Grade
4.0 United States, Canada, many international transcripts 4.0 3.0 2.0
5.0 Weighted / honors / AP high school GPA 5.0 3.5 2.5
10.0 Pakistan, India, Asia (CGPA) 10 8 6

Never mix scales in one calculation. If your transcript uses 10.0 CGPA, calculate on 10.0 here first. Convert to 4.0 only using your target school's official conversion rule — do not guess.

Credits matter because a 4-credit core course weighs four times more than a 1-credit seminar. Averaging letter grades equally (without credits) gives the wrong result.

The GPA Formula with Worked Examples

The standard GPA formula:

GPA = Σ (credits × grade points) ÷ Σ credits

Worked example — 4.0 scale (three courses):

Course Credits Grade Points Quality Points
Physics 4 A (4.0) 4.0 4 × 4.0 = 16.0
History 3 B+ (3.3) 3.3 3 × 3.3 = 9.9
Lab 1 A− (3.7) 3.7 1 × 3.7 = 3.7
Total 8 — — 29.6

GPA = 29.6 ÷ 8 = 3.70

Same grades on 10.0 CGPA scale (illustrative mapping):

Course Credits Grade Points Quality Points
Physics 4 A (10) 10 4 × 10 = 40
History 3 B+ (8.5) 8.5 3 × 8.5 = 25.5
Lab 1 A− (9) 9 1 × 9 = 9
Total 8 — — 74.5

CGPA = 74.5 ÷ 8 = 9.31

Unofficial conversion note: Some people roughly divide 10-scale CGPA by 2.5 to estimate a 4.0-style GPA (9.31 ÷ 2.5 ≈ 3.72). This is only a rough guide — always follow your target university's published conversion table.

Quick reference — 4.0 scale letter mappings:

Grade 4.0 Points 5.0 Points 10.0 Points
A4.05.010
A−3.74.59
B+3.34.08.5
B3.03.58
B−2.73.07
C+2.32.56.5
C2.02.06
D1.01.04

Important Limitations & Common Mistakes

Avoid these errors when calculating GPA:

  • Using the wrong scale: Calculating a Pakistan 10.0 transcript on a 4.0 map will understate your CGPA badly. Always pick the scale printed on your transcript.
  • Ignoring credit weights: Averaging letter grades equally (without credits) is not how registrars compute GPA. A 4-credit course matters more than a 1-credit course.
  • Unofficial conversions for applications: Dividing by 2.5 (10 → 4) or scaling proportionally (5 → 4) is only a rough estimate. Admissions offices publish their own official tables — use those.
  • Mixing pass/fail courses: Some pass/fail or audit credits may be excluded from GPA entirely. Follow your school's policy, not this calculator alone.
  • Semester vs CGPA confusion: Semester GPA covers one term only. CGPA (cumulative) covers all graded credits to date. To approximate CGPA, enter every course from all terms.

Frequently Asked Questions

How is GPA calculated?
Multiply each course's credits by its grade points, add those products, then divide by total credits. Example on 4.0: (3×4.0 + 3×3.0) ÷ 6 = 3.5 GPA.
What is CGPA on a 10 scale (Pakistan / Asia)?
Many universities in Pakistan, India, and Asia use a 10-point CGPA. Choose the 10.0 scale, enter courses and credits, and calculate the same way as GPA — weighted by credits. An 8.0/10 is a strong standing at many schools, but cutoffs vary by program.
How do I convert GPA / CGPA from 10 to 4.0?
Schools use different rules. A rough estimate some people use is ÷ 2.5 (e.g. 8.0/10 ≈ 3.2/4). Always follow your target college's official conversion. This tool calculates within one scale at a time.
How do I convert 5.0 GPA to 4.0?
Weighted 5.0 scales do not map 1:1 to unweighted 4.0. Rough proportional approaches vary by school. Use the matching scale here for your transcript, then ask admissions for official conversion.
What is the difference between 4.0, 5.0, and 10.0?
4.0 is common in the US (A = 4.0). 5.0 is often used for weighted/honors courses. 10.0 CGPA is common in Pakistan and much of Asia. Pick the scale your school prints on the transcript.
Do credits matter, or can I average grades equally?
Credits matter. A 4-credit lab weighs more than a 1-credit seminar. Always enter accurate credit hours so the weighted average matches your registrar's method.
What letter grades map to on each scale?
On 4.0: A=4.0, A−=3.7, B+=3.3, B=3.0, and so on down to F=0. On 5.0 and 10.0 the same letters map to higher point values used by this calculator. Confirm your school's exact map if it differs.
Is semester GPA the same as CGPA?
Semester GPA covers one term. CGPA (or cumulative GPA) covers all graded credits to date. To approximate CGPA, enter every course from all terms with correct credits.
Can I use this for high school and university?
Yes, as long as you know the scale and credit weights your school uses. Some high schools use weighted 5.0 scales for AP/IB; universities may use 4.0 or 10.0.
Is this GPA calculator free?
Yes. No signup. Planning only — your official transcript is the source of truth for applications.
