What this does

Compute your weighted GPA on the 4.0 scale from up to six letter-graded courses and their credit hours.

Using the gpa calculator

  1. 01

    Pick each letter grade

    Set unused course slots to “not taken”.

  2. 02

    Add the credit hours

    Copy them straight from your transcript; labs often carry fewer credits than lectures.

  3. 03

    Read the weighted GPA

    The result matches what your registrar computes, plus per-course quality points.

Credits make grades unequal

An A in a 1-credit seminar cannot rescue a C in a 4-credit core course: the A contributes 4 quality points while the C drags 8. Weighted GPA exists precisely because courses are not created equal.

Plus/minus policies vary

This tool uses the common A=4.0 through F=0.0 mapping including minus grades. Some schools award 4.3 for an A+ or omit minus grades entirely; check your catalog if precision matters for scholarships.

Small courses, big swings

With few total credits, one grade moves the average sharply: a single 3-credit B among 12 credits costs 0.25 GPA points. Early semesters deserve disproportionate attention.

The math behind this calculator

GPA = Σ(grade points × credits) ÷ Σ(credits) A=4.0 A−=3.7 B+=3.3 B=3.0 … F=0.0

Every letter maps to grade points on the standard 4.0 scale. Multiplying by credit hours gives quality points per course; dividing their sum by total credits yields the weighted GPA that registrars report; a 4-credit A outweighs a 1-credit A exactly four times over.

Assumptions & limitations

  • Uses the plain 4.0 scale without plus/minus inflation beyond the listed values.
  • Courses left as “not taken” are excluded entirely.
  • Pass/fail and transfer-excluded courses should be omitted.

Worked example

Earning an A in a 4-credit course, an A− in a 3-credit course and a B in another 3-credit course produces a 3.61 GPA.

Frequently asked questions

How is this different from weighted high-school GPA?
Honors/AP “weighted” GPAs add bonus points above 4.0 (e.g. A=5.0). This calculator uses the standard unweighted college scale.
What happens to courses marked “not taken”?
They are skipped completely; neither their credits nor grade points enter either sum.
Can I include more than six courses?
Batch them: compute each semester separately, then combine semester GPAs using each semester’s credit totals as weights.
Do withdrawals affect GPA?
Usually not; W grades carry no grade points. Exclude withdrawn courses here just like untaken slots.
