How we calculate
GPA = Σ (grade points × credits) ÷ Σ credits
Quality points = grade points × credits. Pass/fail, withdrawn and incomplete courses are left out.

Cumulative GPA adds your prior quality points (prior GPA × prior credits) to this term's and divides by all credits. Weighted GPA adds the bonus you set (commonly +0.5 for honors and +1.0 for AP/IB) to passing grades in those courses, so an A in an AP class counts 5.0.

needed = (target × (credits so far + credits left) − quality points so far) ÷ credits left
The target planner solves the cumulative formula for the GPA you need on the remaining credits.

Schools differ — some don't use A+, cap weighted GPA, or round to two decimals differently. Edit the conversion table to match your school's policy.

  2. 2

    Enter your courses

    Add each course with its credits and grade; add more semesters for a full record.

  3. 3

    Add prior GPA and a target

    Include your transcript GPA and credits for a cumulative result, then set a target to see the average you need on the remaining credits.

Limits and Pro

Free with no account: up to 20 semesters with 40 courses each, three built-in scales with an editable conversion table, and weighting bonuses of up to +2.0 points.

About GPA calculator

List your courses with their credit hours and grades, and the calculator returns the grade point average for each semester and for everything combined, updating as you type. Grades can be entered as letters (A+ to F, plus P for pass/fail courses that don't count) or as percentages that are converted to letters with the table your school uses. Courses, semesters and settings are saved in this browser, so you can come back after the next term and simply add it.

Three scales are built in: the common US 4.0 scale, the 4.3 scale used by schools that award 4.3 for an A+, and a 5-point scale where A is 5, as used by many universities in Nigeria and elsewhere. Every letter's point value and percentage cut-off is editable, because policies differ from school to school. Switch on Weighted to add a bonus for honors and AP or IB classes — +0.5 and +1.0 by default, both adjustable — the way most US high schools compute a weighted GPA for class rank.

A previous-coursework box lets you combine a GPA and credit total from your transcript with the courses you add here to get a cumulative GPA. The planner then answers the question students ask most: what average do I need over my remaining credits to reach a target such as 3.5 for a scholarship, honours or a graduate-school cut-off? It warns when the target is mathematically out of reach. The calculator cannot know your school's rules for repeated courses, transfer credit or rounding, so check the result against your official transcript.

GPA calculator: frequently asked questions

How do I calculate my GPA?
Multiply each course's grade points by its credits, add those quality points up, and divide by the total credits. With English (3 credits, A = 4.0), Calculus (4, B+ = 3.3), Biology (4, A− = 3.7) and History (3, B = 3.0), the quality points are 12 + 13.2 + 14.8 + 9 = 49 over 14 credits, a GPA of 3.50.
What is the difference between weighted and unweighted GPA?
An unweighted GPA treats every class the same on a 4.0 scale. A weighted GPA adds a bonus for harder classes — typically +0.5 for honors and +1.0 for AP or IB — so an A in AP Calculus counts 5.0. A student with an A in AP Calculus and a B in regular English has a 3.5 unweighted GPA but a 4.0 weighted GPA.
How do I work out my cumulative GPA?
Combine quality points, not GPAs. If your transcript shows a 3.2 GPA over 30 credits, that is 96 quality points; adding a semester of 14 credits at 3.5 contributes 49 more. The cumulative GPA is (96 + 49) ÷ 44 = 3.30. Simply averaging 3.2 and 3.5 would give 3.35, which overstates it because the semesters have different credit loads.
What GPA do I need to raise my average to 3.5?
Use the planner: needed = (target × all credits − current quality points) ÷ remaining credits. With a 3.30 GPA over 44 credits and 30 credits left, you need (3.5 × 74 − 145) ÷ 30 = 3.80 on those credits. The more credits you've already earned, the harder it is to move a cumulative GPA, so start early.
How do I convert a percentage grade to a GPA?
Map the percentage to a letter, then the letter to points. On the common US scale, 93–96% is an A (4.0), 90–92% an A− (3.7), 87–89% a B+ (3.3) and 83–86% a B (3.0), so 88% counts as 3.3. Cut-offs differ between schools and countries, which is why the conversion table here can be edited.
