- The weighted GPA updates as you type. Use Copy result or Share to keep it.
Method
Weighted GPA = Σ credits × (grade points + bonus) ÷ Σ credits; Unweighted GPA = Σ credits × grade points ÷ Σ credits
- grade points
- A = 4.0, A− = 3.7, B+ = 3.3 … F = 0
- bonus
- your school’s honors or AP/IB bonus (not added to an F)
- credits
- credits or periods per course
Worked example
- Weighted points: A honors 4.0 + 0.5 = 4.5; B+ AP 3.3 + 1 = 4.3; A− regular 3.7; B regular 3.0.
- Weighted GPA = (4.5 + 4.3 + 3.7 + 3.0) ÷ 4 = 15.5 ÷ 4 = 3.875 ≈ 3.88.
- Unweighted GPA = (4.0 + 3.3 + 3.7 + 3.0) ÷ 4 = 3.5.
These four one-credit courses give a weighted GPA of 3.88 and an unweighted GPA of 3.50.
What the result means
Colleges often recalculate GPA their own way, so report the figure your transcript shows. Weighted GPA rewards course rigour; unweighted GPA compares grades alone.
Assumptions and limits
- Letter grades use the common 4.0 scale (A+ and A = 4.0).
- No bonus is added to a failing grade, a common school policy.
- Schools differ: some cap weighted GPA, weight only certain years, or use a 5.0 or 100-point scale.
Questions
How much does an AP class add?
Most commonly 1.0 point (so an A is 5.0) and honors 0.5, but it is a school policy. Change the bonus fields to match yours.
Which GPA do colleges look at?
Many look at both alongside the courses you took, and some recompute GPA using only core academic subjects.
