How it Works

01Pick Scale

Choose your grading scale — 4.0, 4.3, 5.0, or 10.0.

02Add Courses

Enter each course with its credit hours and grade.

03Credit Weighting

Tool weights each course by credit hours.

04SGPA

Instant credit-weighted Semester GPA + letter grade.

What is a Semester GPA Calculator?

Your SGPA is the credit-weighted average of your course grades — and a 4-credit A is worth more than a 1-credit A. This free Semester GPA calculator computes it correctly for every major scale in under 10 seconds.

Supports four popular grading scales out of the box: University 4.00, BD Private University 4.00 (with A+ ceiling), HSC/SSC Board 5.00, and India CGPA 10.00. Used by students at North South, BRAC, IUB, AIUB, DIU, DU, BUET, and dozens more — switch scales on the fly to match your transcript exactly.

Add unlimited courses, enter decimal credits (1.5 labs, 0.5 seminars), and watch your SGPA, letter grade, total quality points, and percentage equivalent update live. Zero sign-up, zero tracking, fully in-browser.

How the Semester GPA Calculator Works

Step 1 — Select Grading Scale: Choose the scale your university uses. The grade dropdown refreshes to show only valid grades for that scale.
Step 2 — Add Courses: Click + to add each course. Enter a name (optional), credit hours (decimals allowed like 1.5, 3.0), and pick the letter grade you earned.
Step 3 — Credit Weighting: The tool multiplies each course's grade point by its credit hours to get quality points. Total quality points divided by total credits gives the SGPA.
Step 4 — Instant Result: See your SGPA, letter grade, total credits, total quality points, and percentage equivalent in a single results card.
Step 5 — Share or Download: Export the course breakdown as a text file or share a link with your results pre-filled.

The SGPA Formula

Every university in the world with a credit-hour system uses this formula:

SGPA = Σ (credit_hours × grade_point) / Σ credit_hours

The numerator is your total quality points. Quality points are how universities normalize credit weight — a 4-credit A (4 × 4.0 = 16 quality points) counts more than a 3-credit A (3 × 4.0 = 12 quality points).

The percentage equivalent is approximate and depends on the scale:

  • 4.00 scale → SGPA × 25
  • 5.00 scale → SGPA × 20
  • 10.00 scale → SGPA × 10
Real-World Example

Calculation In Practice

Worked example — 4 courses on the University 4.00 scale:

  • Data Structures: 3 credits × A (4.00) = 12.00 QP
  • Calculus II: 4 credits × B+ (3.30) = 13.20 QP
  • English: 3 credits × A- (3.70) = 11.10 QP
  • Programming Lab: 1 credit × A (4.00) = 4.00 QP

Total credits = 11. Total quality points = 40.30. SGPA = 40.30 / 11 = 3.66 (letter grade A-).

Who Should Use the Semester GPA Calculator?

1
University students estimating their SGPA before official results are published.
2
Private University (BD) students on the 4.00 scale with A+ ceiling who need an accurate credit-weighted tool.
3
Public University students verifying their printed transcript for data-entry errors.
4
Admission applicants filling out applications that require an exact SGPA with precision to 2+ decimals.
5
Scholarship aspirants projecting whether their SGPA meets GPA cutoff thresholds (3.50, 3.75, etc.).

Technical Reference

Supported Grading Scales:

  • University 4.00 (standard): A+/A 4.00, A- 3.70, B+ 3.30, B 3.00, B- 2.70, C+ 2.30, C 2.00, C- 1.70, D 1.00, F 0.00.
  • BD Private University 4.00 with A+: A+ 4.00 (80+), A 3.75, A- 3.50, B+ 3.25, B 3.00, B- 2.75, C+ 2.50, C 2.25, D 2.00, F 0.00.
  • HSC/SSC Board 5.00: A+ 5.00, A 4.00, A- 3.50, B 3.00, C 2.00, D 1.00, F 0.00.
  • India CGPA 10.00: O 10.00, A+ 9.00, A 8.00, B+ 7.00, B 6.00, C 5.00, F 0.00.

Credit Hour Handling: Decimal credits are allowed (e.g., 1.5, 0.5). Zero-credit courses are ignored in SGPA computation.

Failed Courses: Grades of F contribute 0 quality points but still count toward total attempted credits, pulling your SGPA down.

Key Takeaways

Credit weighting is what separates SGPA from a simple average. Heavier courses (more credits) pull your SGPA more strongly — both ways. The credit hours you take each semester shape how much each grade matters to your final number.

Use this tool every semester to verify your transcript, plan future semesters, and decide which courses to prioritize studying for based on their credit weight.

Frequently Asked Questions

What is Semester GPA (SGPA)?
SGPA is the credit-weighted average of your grade points for one academic term. Each course contributes to your GPA in proportion to its credit hours — a 4-credit course counts more than a 1-credit lab.
How is SGPA calculated?
SGPA = sum of (credit hours × grade point) / sum of credit hours. A 4-credit A contributes 16 quality points; a 1-credit A contributes only 4. Heavier courses pull your SGPA harder.
Which grading scales does this support?
Four popular scales: University 4.00 standard, Bangladesh Private University 4.00 with A+ ceiling, HSC/SSC Board 5.00, and India CGPA 10.00. Switch on the fly.
Can I compute cumulative CGPA from this?
This tool computes one semester at a time. To aggregate multiple semesters into a CGPA, use our SGPA-to-CGPA calculator — it takes each semester's SGPA and credits as input.
What happens if I fail a course?
An F gets 0 grade points but the credits still count in the denominator, which drags your SGPA down significantly. Retaking the course and replacing the F usually lifts SGPA the most.
Can I enter decimal credit hours?
Yes. The calculator supports fractional credits like 1.5 or 0.5 for labs, seminars, and variable-credit courses common in BD and Indian university programs.
Does this work for North South, BRAC, IUB, AIUB, DIU?
Yes. Private universities in Bangladesh typically use the 4.00 scale with A+ ceiling — pick the 'BD Private University' scale and you'll get results matching your transcript.
How is this different from a simple average?
A simple average treats every course equally. SGPA weights each course by its credit hours, which is how every credit-hour university grades and ranks students — the correct academic number.
What is my percentage equivalent?
The tool auto-shows percentage equivalent using standard approximations: 4.0-scale × 25, 5.0-scale × 20, 10.0-scale × 10. Use this for forms that require percentage rather than GPA.
Can I save or share my result?
Yes. Export the course breakdown as a text file, or share a URL with your courses pre-filled — the calculator reopens with your exact data intact.
