How to use this calculator
- Enter each class — no credit column here, every class counts equally.
- Pick the grade — letters, or switch to Percentage input.
- Set the course type if you want the weighted comparison (Honors +0.5, AP/IB +1.0).
- Add semesters to average across terms — each shows its own GPA.
- Read both results — unweighted highlighted, weighted alongside.
How GPA works without credit hours
When credits are out of the picture, GPA becomes a plain average. Convert each grade to points, add them, divide by the number of classes:
GPA = sum of grade points ÷ number of classes
So five classes graded A, A-, B+, B, A convert to 4.0 + 3.7 + 3.3 + 3.0 + 4.0 = 18.0 points, and 18.0 ÷ 5 = 3.60. The Type column still works: mark a class Honors (+0.5) or AP/IB (+1.0) and the weighted result reflects it.
When the no-credits method is right
- Your school doesn't publish credit hours. Many high schools — especially outside the US — grade by subject with no credit system at all.
- All your classes are worth the same credits. If every course is 1.0 credit, the equal-weight average and the credit-weighted average are mathematically identical, so this simpler tool gives the exact same answer.
- You want a quick estimate. Mid-semester sanity checks don't need credit bookkeeping.
The one case to be careful with: schools that mix full-credit academic classes with half-credit electives (health, PE, semester arts). There, a half-credit class should pull only half as hard on your average — switch to the full calculator with credits for a transcript-accurate number.
Frequently asked questions
Will my no-credits GPA match my transcript?
If all your classes carry equal credit, yes, exactly. If your school mixes credit values, expect small differences — the transcript version weights bigger classes more heavily.
Can I calculate a cumulative GPA without credits?
Yes — treat each semester class as 1 credit. In the cumulative GPA calculator, enter the total number of semester classes you've taken as your "credits earned."
How do I convert my average to a letter or percentage?
The 4.0 scale maps roughly to letters as A = 3.7–4.0, B = 2.7–3.6, C = 1.7–2.6. Percentage conversions vary by school; the common approximation is 4.0 ≈ 93–100%. Details in the GPA scale explained.
