GPA Calculator

This free GPA Calculator works out your semester or cumulative GPA on the unweighted 4.0 scale from each course's letter grade and credit hours. Three courses (an A in a 3-credit class, a B+ in a 4-credit class and an A- in a 3-credit class) come to 36.3 quality points over 10 credits, a 3.63 GPA.

Uses the standard unweighted 4.0 scale (A=4.0, A-=3.7, B+=3.3 … F=0.0). Your school may use a different scale - check your registrar's grading policy if you need an exact match.

Calculate Your GPA on the 4.0 Scale

The Tools Kit's free GPA Calculator works out your grade point average from the letter grade and credit hours of each course. Use it as a semester GPA calculator for one term, or list every course on your transcript to get your cumulative college or high school GPA. The result is weighted by credits, so a 4-credit class moves your GPA more than a 1-credit one.

GPA = total quality points ÷ total credits, where quality points = grade points × credit hours. An A in a 3-credit class, a B+ in a 4-credit class and an A- in a 3-credit class give (12 + 13.2 + 11.1) ÷ 10 = 3.63. Everything is calculated in your browser, with no signup.

How to Use the GPA Calculator

  1. 1

    Choose a grade for each course

    Pick the letter grade you earned (or expect) from the dropdown, anywhere from A+ down to F.

  2. 2

    Enter the credit hours

    Type the number of credits or credit hours the course is worth. Decimal values such as 1.5 are accepted.

  3. 3

    Add or remove courses

    Use "+ Add course" for every extra class in your semester or transcript, and the remove button to delete a row you do not need.

  4. 4

    Read your GPA

    Your GPA on the 4.0 scale, total credits and quality points update instantly as you edit any row.

A row with blank or zero credits is skipped rather than counted as a failing grade, so a half-filled row never drags your GPA down.

4.0 GPA Scale: Letter Grades to Grade Points

The calculator uses the standard unweighted 4.0 scale common at US colleges and high schools. Each plus or minus shifts the value by roughly 0.3 points, and A+ is capped at 4.0.

Letter gradeGrade points
A+ / A4.0
A-3.7
B+3.3
B3.0
B-2.7
C+2.3
C2.0
C-1.7
D+1.3
D1.0
D-0.7
F0.0

If your course grades are still percentages, the grade calculator turns weighted assignment scores into an overall class grade and letter first, and the percentage calculator handles a quick score such as 43 out of 50. Some schools give A+ a 4.3 or use different plus/minus values; check your registrar's grading policy if you need an exact match.

Semester GPA vs Cumulative GPA

Your semester GPA covers one term. Suppose you took a B (3 credits), B- (3), B+ (4), A (3) and C (2). The quality points are 9 + 8.1 + 13.2 + 12 + 4 = 46.3 over 15 credits, which is a 3.09 semester GPA.

Your cumulative GPA covers every graded course so far. The simplest way to calculate it here is to add every course from every term as its own row. There is no box for a previous GPA, so if you only know your old GPA and credits, combine them by hand: (old GPA × old credits + new quality points) ÷ total credits. A 3.2 GPA over 30 credits is 96 quality points; add a semester worth 51 quality points over 15 credits and you get 147 ÷ 45 = 3.27. Do not average semester GPAs, because that ignores how many credits each term carried.

How to Raise Your GPA: What Grades Do You Need?

To plan a target GPA, work in quality points. A student with a 3.0 over 60 credits has 180 quality points. Reaching a 3.2 after 15 more credits takes 3.2 × 75 = 240 points, so the next 15 credits must earn 60 points: a 4.0, straight-A semester. Spread over 30 credits instead, the target is 3.2 × 90 = 288 points, so those 30 credits need 108 points, a 3.6 average. The more credits you have banked, the harder it is to move your GPA quickly.

Try it by adding the grades you expect for next semester as extra rows alongside your completed courses. Planning study time helps too: a Pomodoro timer keeps revision sessions focused, and the days calculator counts how many days are left until finals or the end of term.

Weighted vs Unweighted GPA

An unweighted GPA treats every class the same on a 4.0 scale. A weighted GPA, used by many high schools, adds extra points for honors, AP or IB classes, so it can go above 4.0. This calculator gives the unweighted figure: it does not add a bonus for advanced courses. Many colleges recalculate applicants' GPAs on an unweighted basis anyway, so it is a useful number to know.

Common uses

  • Checking your semester GPA before your school posts official grades
  • Calculating a cumulative college GPA across several terms
  • Working out a high school GPA for college applications (unweighted)
  • Checking whether you meet a scholarship, honors or graduate-school GPA cutoff
  • Planning the grades you need next semester to reach a target GPA

For the rest of your coursework, the word counter checks essay length limits and the citation generator formats references in APA, MLA and other styles. UK students weighing up repayments can use the UK student loan calculator, and more number tools are in the calculator tools collection.

GPA terms explained

TermWhat it means here
GPAGrade point average: the credit-weighted average of your grade points
Grade pointsThe number a letter grade is worth on the 4.0 scale, such as 3.3 for a B+
Credit hours / creditsHow much a course counts toward your degree; a 4-credit course weighs more than a 3-credit one
Quality pointsGrade points multiplied by credit hours for one course, or the total across all courses
Semester GPAThe GPA for the courses taken in a single term
Cumulative GPAThe GPA across every graded course on your transcript, not an average of semester GPAs
Unweighted GPAA GPA where every class uses the same 4.0 scale, with no bonus for honors or AP courses
Weighted GPAA GPA that adds extra points for honors, AP or IB courses, so it can exceed 4.0; this calculator does not apply those bonuses

How do you calculate your GPA?

GPA is the credit-weighted average of grade points. Multiply each course's grade points by its credit hours, add those products, then divide by total credit hours. On a 4.0 scale an A is 4.0, B is 3.0, C is 2.0. Heavier courses move a GPA more.
