How this calculator works
A semester GPA — often written SGPA — answers a narrow, useful question: how did this one semester go, weighted by the size of each course? It is the building block of the cumulative number, and it is easier to compute than most students think. Enter each course’s credit hours and the letter grade you earned, and the calculator produces the weighted average immediately.
The formula, in one line
Semester GPA (SGPA)
SGPA = Σ (credit hours × grade points) ÷ Σ (credit hours)
In plain words: every course contributes its credit hours multiplied by its grade point value, you add those up, and you divide by the total credit hours. A 3-credit A contributes 12 quality points; a 4-credit C+ contributes 9.32 on the common 4.0 scale. Bigger courses pull the average harder — that is the whole design of a credit-weighted GPA.
Worked through with real numbers
Say your semester is five courses: two 3-credit courses with an A (4.00) each, one 3-credit course with a B (3.00), one 3-credit course with a B− (2.67) and one 1-credit lab with an A. The quality points are 12.00 + 12.00 + 9.00 + 8.01 + 4.00 = 45.01 over 13 credit hours, giving an SGPA of 45.01 ÷ 13 = 3.46. Notice how the single-credit lab barely moves the needle — and how one B and one B− cost far more than the lab could ever recover.
Getting a result that matches your university’s
- Use the exact grade points from your handbook.Defaults like A− = 3.67 and B− = 2.67 are common, but plenty of institutions use 3.70 and 2.70, or different letters altogether. The scale editor exists precisely for this.
- Watch for pass/fail and non-credit courses. Courses that carry no grade points or no credit hours are normally excluded from a GPA — simply leave them out, or give them 0 credit hours.
- Mind the rounding. Most universities round the final average to two decimals. This calculator rounds only the displayed result, never the underlying sums.
Where to go next
Once your semester’s SGPA is in hand, the natural next step is the cumulative picture: the CGPA calculator combines multiple semesters, and the improvement planner turns a target CGPA into a concrete average you need going forward. If results are not out yet, the what-if planner lets you rehearse the outcome first. And remember: this is a planning tool — your university’s official records are the final word.
