GPA Calculator
Work out your GPA from letter grades and credit hours.
Calculating a GPA
Add each course with its letter grade and credit hours. Grades convert to points โ A = 4.0, B = 3.0, plus/minus steps of 0.3 โ each multiplied by the course's credits, and GPA is total points over total credits. The weighting is what mental estimates miss: a 4-credit B pulls your average harder than a 1-credit A lifts it.
To update a running average, enter your previous cumulative GPA and total credits and the calculator combines them with this semester properly โ weighted by credits, not averaged as two numbers.
The caveats that matter
Institutions differ: some award 4.3 for A+, some have no minus grades, many exclude pass/fail courses from GPA entirely, and weighted high-school scales add points for honours and AP classes so they run above 4.0. This calculator implements the most common unweighted 4.0 table โ when a scholarship or application hangs on the number, verify against your institution's own published scale, which registrars always publish.
Working backwards โ "what do I need this term to reach 3.5 overall?" โ is the final grade calculator's territory, applied per course.
Frequently asked questions
How is GPA calculated?
Each grade's point value (A=4.0, B=3.0โฆ) is multiplied by the course's credit hours; GPA is the total grade points divided by total credits.
What GPA is a B+ average?
3.3 on the standard scale. The plus and minus steps are 0.3: Bโ is 2.7, B is 3.0, B+ is 3.3, Aโ is 3.7.
How do I calculate cumulative GPA?
Weight by credits: previous GPA ร previous credits, plus this semester's grade points, divided by the combined credits. The optional fields below the table do it for you.
Is an A+ worth more than an A?
On the standard 4.0 scale both are 4.0, which this calculator uses. Some institutions award 4.3 for A+ โ check your school's table.
