GPA is a credit-weighted average, not a simple average of your grades. Each course's letter grade is converted to grade points (on a 4.0 scale, A is 4.0, B is 3.0, C is 2.0, and so on), then multiplied by that course's credit hours. You add up all those products to get total quality points, then divide by the total credits attempted. Because of the weighting, a 4-credit course moves your average twice as much as a 2-credit one, so a strong grade in a heavy course counts more than the same grade in a light one. Doing this by hand across many classes is error-prone, especially with mixed credit values. Enter each course's grade and credits in the calculator and it applies this formula automatically, returning your GPA instantly.

A semester GPA reflects only the courses taken in a single term, while a cumulative GPA averages every course across all terms, weighted by credit hours. Your semester GPA can swing widely from one term to the next, but the cumulative figure changes more slowly because it carries the weight of every credit you have already earned. That is why one rough semester hurts less once you have many credits behind you, and why early grades have an outsized long-term effect. This tool reports both: a semester GPA for each term you add and a running cumulative total across all of them. You can also enter prior credits and an existing GPA from a transfer or earlier years, and it folds those into the cumulative result so the number matches your full transcript.

Different institutions report grades on different scales, so converting requires mapping your grades onto the target scale rather than using one universal formula. This calculator includes eight scales: the US 4.0 scale, a 4.0 scale with plus and minus grades, a 4.3 scale, a 5.0 scale, the 10.0 scale used for Indian CGPA, a straight 0-100 percentage scale, the UK honours classification, and a Canadian scale. Pick the scale your institution actually uses and the grade options update to match it, so a 10-point CGPA or a percentage is interpreted correctly instead of being forced into 4.0 assumptions. A built-in letter-to-percentage reference table also shows typical bands, such as an A being roughly 93-96% on the US scale. Select your scale, enter your grades, and read the resulting GPA directly.

A standard unweighted GPA caps at 4.0 because an A is worth exactly 4.0 grade points. A weighted GPA adds bonus points for harder courses, which is why it can climb above 4.0. In this calculator, turning on the weighted GPA toggle adds 0.5 to each Honors course's points and 1.0 to each AP or IB course's points before averaging, rewarding students who take a more demanding course load. So a student with straight As in several AP classes can finish with a weighted GPA above 4.0, while their unweighted GPA stays at 4.0. Keep in mind many colleges recalculate an unweighted GPA from your transcript anyway, so it helps to know both numbers. Leave the toggle off for the standard average, or switch it on to see how advanced coursework lifts your weighted figure.

Reaching a target GPA depends on how many credits you have already completed and how many remain, because each new credit can only shift your cumulative average so far. The math works backward from your goal: it figures out the total quality points you still need, subtracts what you already have, and divides by your remaining credits to find the average grade required. This calculator's Target GPA tool does exactly that. Enter the GPA you want and the number of credits left, and it tells you the average grade you would need across those credits, and it flags when a target has become mathematically unreachable. There is also a What-If simulator that lets you change a grade hypothetically and watch your projected cumulative GPA update, so you can plan retakes or course loads before committing to them.
