GPA Calculator
Work out your semester and cumulative GPA from letter grades and credits, weighted or unweighted, and see what you need on the final.
Enter a letter grade and credit hours for each course. Pick Honors or AP/IB for a weighted GPA. Results update as you type.
Add previous semesters for cumulative GPA
Enter the cumulative GPA and total credits from your transcript. Your new cumulative GPA includes this semester.
Find the score you need on your final exam to finish the class with the grade you want.
Tip: common cut-offs are 90% for an A, 80% for a B and 70% for a C.
| Final score | Final grade |

How to use the GPA calculator
- Pick a letter grade and enter the credit hours for each course. Use Add course for more rows and × to remove one.
- For high school, set the type to Honors or AP / IB to see your weighted GPA alongside the unweighted one.
- To get your cumulative GPA, open Add previous semesters and enter your current GPA and credits completed.
- Your courses are remembered on this device, so you can come back later. Use the Final grade tab to plan your last exam.
What is a GPA and how is it calculated?
Your grade point average (GPA) turns letter grades into a single number, usually on a 4.0 scale. Each letter has a point value: A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0, C− = 1.7, D+ = 1.3, D = 1.0, D− = 0.7 and F = 0. Some schools count an A+ as 4.3; switch the A+ counts as option if yours does.
GPA is weighted by credit hours. Multiply each grade’s points by the course credits to get quality points, add them up and divide by the total credits:
GPA = Σ (grade points × credits) ÷ Σ credits
For example, an A in a 3-credit class (12 points), a B+ in a 4-credit class (13.2 points) and a B in a 3-credit class (9 points) add up to 34.2 quality points over 10 credits, a GPA of 3.42.
Weighted vs. unweighted GPA
Many high schools reward harder classes. An unweighted GPA treats every class the same and tops out at 4.0. A weighted GPA adds a bonus for advanced courses, typically +0.5 for Honors and +1.0 for AP or IB, so an A in an AP class is worth 5.0. Colleges often recalculate GPAs their own way, so it helps to know both. The calculator shows both whenever you mark a course as Honors or AP/IB. Failing grades get no bonus.
Semester vs. cumulative GPA
Your semester GPA covers one term; your cumulative GPA covers every course on your transcript. To combine them, multiply your previous GPA by the credits you have already earned, add this term’s quality points and divide by the new credit total. The Add previous semesters box does this for you.
What do I need on the final?
If the final is worth w% of the course, your final grade is current × (1 − w) + final × w. Solving for the final gives:
needed = (target − current × (1 − w)) ÷ w
With an 84% now, a final worth 30% and a 85% goal, you need (85 − 84 × 0.7) ÷ 0.3 = 87.33…, so at least 87.34%. The Final grade tab also shows a table of what different final scores would give you, so you can set a realistic target.
Tips for raising your GPA
- Focus on high-credit classes: a grade change in a 4-credit course moves your GPA more than one in a 1-credit course.
- Know your school’s policy: retaken courses, pass/fail and withdrawals are handled differently from school to school.
- Plan early: the more credits you have, the slower your cumulative GPA moves, so every early semester counts.

Frequently asked questions
How do I calculate my GPA?
Multiply each course’s grade points (A = 4, B = 3, C = 2, D = 1, F = 0) by its credit hours, add the results and divide by your total credits. This calculator does it instantly as you enter your grades.
What is the difference between weighted and unweighted GPA?
An unweighted GPA uses the standard 4.0 scale for every class. A weighted GPA gives extra points for harder classes, usually +0.5 for Honors and +1.0 for AP or IB, so it can go above 4.0.
How do I calculate my cumulative GPA?
Multiply your current cumulative GPA by the credits you have completed, add this semester’s quality points, then divide by the total of old and new credits. Enter your previous GPA and credits in the Add previous semesters box and the calculator does it for you.
Is a 3.5 GPA good?
Yes. A 3.5 is between a B+ and an A− average and is above the average GPA at most US colleges. Many schools use 3.5 as the cut-off for the dean’s list or honors.
Are my grades saved or sent anywhere?
Your courses are saved only in your own browser on this device, so they are still there when you come back. Nothing is sent to a server. Press Clear to remove them at any time.
