Semester GPA Calculator, Free and Online
A semester GPA calculator works out your grade point average for a single term by weighting each course's grade points against its credit hours. This one supports the US 4.0 scale plus UK, Indian, Pakistani and Australian grading systems, and updates live as you add courses, entirely inside your browser.
Every student calculates semester GPA at some point, usually while checking eligibility or just curious how a term turned out. This free semester GPA calculator tool does it instantly. Add each course with its credit hours and letter grade, and your semester GPA, letter equivalent, total credits and quality points update the moment anything changes, alongside a grade distribution breakdown. Pro Mode adds a cumulative GPA calculator that folds this semester into your full academic record, a target GPA planner that works out what you need this term to hit an overall goal, a what-if simulator for testing hypothetical grade changes, best and worst case scenarios, an honor roll and course impact breakdown, and a multi-semester tracker for watching your GPA progress over time.
Each course contributes quality points equal to its grade points multiplied by its credit hours. Add up every course's quality points, then divide by total credits, to get your semester GPA.

2Semester GPA, Quick Examples
The mistake that trips up the most students is picking a GPA Scale that does not match the Grading System they selected. A 10.0 scale is meant to pair with a 10 point system like India's UGC grades, not with a standard US A to F system, and mixing the two produces a number that looks plausible but is not mathematically meaningful. Always confirm the GPA Scale and Grading System dropdowns match your actual institution before trusting the result for anything official.
3Where the Modern GPA Scale Actually Came From
The number every student now tracks to two decimal places started as a diary entry. According to Yale's own institutional research archive, in historian George Pierson's Yale Book of Numbers 1701 to 1976, the first recorded grades in American higher education date to 1785, when Yale president Ezra Stiles examined 58 seniors and sorted them into four Latin ranked categories in his personal diary. Yale kept building on this system in what it called the Book of Averages, and by 1837 the university had converted those descriptive ranks into a numeric four point scale, the direct ancestor of the 4.0 GPA nearly every American student now uses. Letter grades came much later and from a different institution entirely, Mount Holyoke College introduced the familiar A through F system in 1897, more than a century after Yale's first numeric scale.
