GPA Calculator

A GPA calculator converts your letter grades and credit hours into a single grade point average on the standard 4.0 scale. It multiplies the point value of each grade by the number of credits that course carries, adds those products together, and divides by the total credits. That credit-weighted mean is your GPA, and it is the number registrars, scholarship committees, and admissions offices read first.

This calculator handles both of the systems schools use. An unweighted GPA maps every course to the same 0 to 4.0 range regardless of difficulty, so an A is always 4.0. A weighted GPA rewards harder classes by adding a bonus before the average is taken, most commonly 0.5 for Honors and 1.0 for Advanced Placement or International Baccalaureate courses, which is why a weighted GPA can climb above 4.0. Toggle weighting on and the tool shows both figures side by side so you can report whichever your school expects.

Because grades arrive one term at a time, the calculator also rolls a new semester into a running total: enter your prior cumulative GPA and the credits behind it, and it returns an updated cumulative GPA without you re-entering every past course. Used this way it is a semester cumulative GPA calculator: with a 3.20 GPA over 45 credits and a new 15-credit semester averaging 3.60, the updated cumulative GPA is 3.30. Everything runs entirely in your browser, so no transcript data is uploaded, nothing is stored, and the tool keeps working offline once the page has loaded.

The 4.0 scale is a convention rather than a standard, and institutions differ in ways that change the number. Some award 4.3 for an A plus and some cap the scale at 4.0, so an A plus either helps or does nothing depending on where you study. Weighted scales differ more: adding a full point for AP and half for Honors is common but not universal, and a transcript weighted one way does not compare directly to one weighted another. Credit hours do the real work in the average, so a four-credit course moves your GPA twice as much as a two-credit one, which is why a poor grade in a lab-heavy term is felt so strongly. Check your institution's published scale before relying on the figure for an application.
