How GPA is calculated
Your GPA is a weighted average: each grade is converted to grade points, multiplied by the course credits, added up, and divided by your total credits. A 4-credit A therefore counts more than a 1-credit A. The formula is: GPA = total grade points divided by total credits.
Weighted vs unweighted GPA
An unweighted GPA uses the plain 4.0 scale, so the highest possible GPA is 4.0. A weighted GPA rewards harder courses: on the 4.0 scale, Honours courses add 0.5 and AP courses add 1.0 to each grade point, so a weighted GPA can rise above 4.0. Always check which version your school or college asks for - they are not interchangeable.
Semester vs cumulative GPA
Semester GPA covers just one term's courses. Cumulative GPA combines every term so far: it weights your previous GPA by your previous credits and your current semester GPA by your current credits, then divides by the total credits. That is why early results keep influencing your cumulative GPA, but their influence shrinks as you earn more credits.
Target-GPA planner
Set the GPA you want and how many credits remain, and the planner works out the average grade you need in those remaining credits, in plain words. If the required average is above the top of your scale, it will say plainly that the target is not reachable with the remaining credits alone - you would need more credits, or a different target.
FAQ
Is my GPA the same everywhere?
No. Schools and colleges use different scales, grade-point values and weighting rules. This calculator uses the common US 4.0 and 4.33 scales, but always confirm your institution's own scale before submitting an official figure.
What about +/- grades?
On the 4.33 scale, plus and minus grades have their own values - for example, A- is 3.67 and B+ is 3.33 - and the scale table above shows them. On the plain 4.0 scale, only whole letter grades are used.
What about pass/fail courses?
Pass/fail courses usually do not count toward GPA. Leave them out of the calculator entirely - do not enter them as an A or an F - unless your institution specifically tells you to include them.
How can I raise my GPA?
Focus on high-credit courses, because they move the average most, and use the target planner to see exactly what average you need next. Retaking a low-grade course may help if your institution replaces the old grade - check its policy first, as many schools average both attempts instead.
