College GPA Calculator

This college GPA calculator does GPA the way registrars do — every course’s grade points multiplied by its credit hours, divided by total credits. A 4-credit A moves the needle more than a 1-credit lab, exactly as it should. Enter up to four courses with their credits for a semester GPA that matches your transcript math.

How it was calculated

  1. Course 1 (A): 4.0 × 4 cr = 16.0 pts.
  2. Course 2 (B+): 3.3 × 3 cr = 9.9 pts.
  3. Course 3 (C): 2.0 × 3 cr = 6.0 pts.
  4. Course 4 (A−): 3.7 × 4 cr = 14.8 pts.
  5. GPA: 46.7 ÷ 14 credits = 3.336.

How it works

College GPA is credit-weighted: multiply each course’s grade points by its credit hours, add those products into total grade points, then divide by total credit hours.

Credit hours act as the weights, so a 4-credit course influences the GPA four times as much as a 1-credit course with the same grade.

Grade points use the standard 4.0 plus/minus table: A/A+ = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0, C− = 1.7, D+ = 1.3, D = 1.0, D− = 0.7, F = 0.

Worked examples

A (4cr), B+ (3cr), C (3cr), A− (4cr)

Grade points: 16.0 + 9.9 + 6.0 + 14.8 = 46.7 over 14 credits → 3.336 GPA. Note the plain average of the four grades would be 3.25 — the heavier A courses pull it up.

B (3cr), B (3cr), A (4cr), C (2cr)

Grade points: 9.0 + 9.0 + 16.0 + 4.0 = 38.0 over 12 credits → 3.167 GPA. The 2-credit C barely dents the result compared with the 4-credit A.

How to measure

  • Take credit hours from the course catalog or your schedule — not from weekly class hours, which can differ (labs especially).
  • Use the transcript letter grade, including plus/minus exactly as recorded; a B+ and a B differ by 0.3 points.
  • Exclude pass/fail, audit, and withdrawal courses — they carry credits but no grade points in standard GPA math.
  • For in-progress semesters, this gives a projected GPA; replace estimates with final grades when posted.
  • Double-check repeated courses against your school’s policy — many count only the latest attempt.

Assumptions & limitations

Frequently asked questions

Each letter grade converts to points (A = 4.0 down to F = 0), multiplied by the course’s credit hours to get grade points. Add all grade points, divide by total credit hours. A 4-credit A (16 points) counts double a 2-credit A (8 points) — that is the whole idea.

Because a 4-credit course represents roughly four times the work of a 1-credit course. Weighting by credits makes the GPA reflect total academic effort rather than treating a weekly lab and a daily lecture as equals.

Yes, and painfully: an F contributes 0 grade points but its credit hours still count in the divisor. A 3-credit F drags a GPA down exactly as much as a 3-credit A lifts it. This is why withdrawals (which usually exclude the course) exist.

GPA here means one term’s average; CGPA (cumulative GPA) averages grade points across all terms, weighted by each term’s credits. Use this calculator per semester, then the CGPA Calculator to roll them together.

Yes: just pick the straight letters (A, B, C, D, F) and ignore the plus/minus options. The math is identical; you simply will not use the in-between point values.
