What is GPA Calculator?

Your Grade Point Average summarizes performance across multiple subjects into one number, but a plain average of grades isn't accurate when some subjects carry more credit hours than others โ€” a 4-credit course should count more toward your GPA than a 1-credit elective. This calculator lets you enter each subject's grade and its credit weight so it can produce a properly weighted GPA, the same method used by most Indian engineering colleges and US universities on the 4.0 (or 10-point) scale.

Weighted GPA Formula

Each subject contributes "points" equal to its grade multiplied by its credit value, and the overall GPA is the sum of those points divided by total credits attempted:

GPA = ฮฃ(Grade ร— Credit) รท ฮฃ(Credit)

Worked Example

Say a student has three subjects in a semester:

SubjectGradeCreditsPoints
Subject A4.0312.0
Subject B3.5414.0
Subject C3.039.0

Total points = 12.0 + 14.0 + 9.0 = 35.0, and total credits = 3 + 4 + 3 = 10.

GPA = 35.0 รท 10 = 3.5

So this student's weighted GPA for the semester comes out to 3.5.

How to Use This Calculator

  1. Enter the grade points earned in Grade Points (Subject 1).
  2. Enter the credit weight of that subject in Credits (Subject 1).
  3. Repeat for each additional subject row.
  4. Click Calculate to get your combined weighted GPA.
๐Ÿ’ก Tip: Grading scales differ between institutions โ€” many Indian universities use a 10-point scale while US colleges typically use 4.0. Enter grade points on the same scale your institution issues, since mixing scales distorts the result.

Why the Weighting Matters

If you simply averaged the raw grades 4.0, 3.5, and 3.0 without considering credits, you'd get (4.0+3.5+3.0)รท3 = 3.5 โ€” which happens to match in this particular example only because the numbers were chosen conveniently. In practice, a semester with a high grade in a 1-credit lab and a lower grade in a 4-credit core subject would produce a noticeably different unweighted average versus a properly weighted GPA, which is exactly why colleges insist on the credit-weighted formula rather than a flat average.
