Weighted vs Unweighted GPA: What Is the Difference?
An unweighted GPA measures grades without adding points for harder courses. A weighted GPA may give extra points for honors, AP or other advanced classes, according to the school's rules. There is another kind of weighting too: course credits. That distinction explains why a credit-weighted calculator can still report an unweighted GPA.
What does unweighted mean?
On this calculator's 4.0 scale, A and A+ are 4.0, B is 3.0 and F is zero. Plus and minus grades have their own values, such as B+ at 3.3 and A− at 3.7. No extra points are added for course difficulty.
Some schools use different grade mappings or rules for repeated and pass/fail courses. Check the scale on your transcript before treating an online estimate as an official GPA.
What does a weighted school GPA mean?
Schools may add a difficulty bonus for selected advanced courses. For illustration only, a school that gives an advanced-course A 5.0 instead of 4.0 would report a different average. There is no single universal weighted scale.
With two equal-credit A grades, one regular and one advanced, that example policy gives (4 + 5) ÷ 2 = 4.50 weighted, compared with 4.00 unweighted. This is a hypothetical policy, not a setting in this calculator.
Why do credits still matter?
Credit weighting means a course counts in proportion to its credits. An A in a three-credit course contributes 4 × 3 = 12 quality points. A B in a four-credit course contributes 3 × 4 = 12. Divide 24 total quality points by seven credits to get about 3.43.
Simply averaging 4 and 3 would give 3.50 and ignore the larger B course. The result remains unweighted in the course-difficulty sense, even though credits affect the average.
Try the supported example
Open the GPA Calculator, keep two course rows and enter A with 3 credits and B with 4 credits. Remove any other rows. The result is 3.43 on the 4.0 scale with seven total credits.
This calculator has grade and credit inputs, but no honors/AP bonus or custom scale. Use it for the supported unweighted scale, and use your school's rules or transcript for an official weighted figure.
Which GPA should you report?
Follow the application or institution's instructions. Include the scale when asked, and do not silently convert a weighted GPA to an unweighted one. A GPA number without its scale and policy can be misleading.
