About this tool
This GPA calculator handles the scales students actually meet. Use the standard US 4.0 scale with plus and minus grades, the 4.3 scale where an A+ is worth more, or the weighted high-school scale where Honours classes add half a point and AP or IB classes add a full point. You can also type percentage marks and have them turned into letters, use the Australian 7-point GPA from High Distinction to Fail, or estimate a UK degree classification from module marks and credits.
Each course has a grade and its credits, so a four-credit lab counts for more than a one-credit elective. Add as many rows as you need, remove the ones you don’t, and the result updates as you type. Two more cards answer the questions that come next: what your cumulative GPA is once earlier terms are included, and what average you need in your remaining credits to reach a target, including a clear warning when a target is no longer reachable.
Your courses are saved in this browser only, so they are still there when you come back, and nothing is ever sent to a server.
How to use GPA Calculator
- Choose your system under “Grading scale”, for example “US 4.0” or “UK degree class”.
- For each course, pick the grade (or type the mark out of 100) and its credits. Course names are optional.
- Tap “Add course” for more rows, or the × at the end of a row to remove one. Pressing Enter in the last credits box adds a row too.
- Read your result in the “This term” card and tap “Copy summary” to keep a copy.
- Fill in “Cumulative” with your earlier GPA and credits, and “What do I need?” with your target.
An A in a 3-credit class, a B+ in a 4-credit class, a C in a 3-credit class and an A− in a 2-credit class gives (12 + 13.2 + 6 + 7.4) ÷ 12 credits = 3.22. Add an earlier 3.50 over 30 credits and the cumulative GPA is 3.42. To finish on 3.60 after 30 more credits, you need 3.85.

- Percentage marks turned into letters and grade points using common US cut-offs, with the letter shown in each row.
- Australian 7-point GPA: HD 7, D 6, C 5, P 4, Fail 0.
- UK credit-weighted average mark with the degree class it points to and a borderline warning.
- Cumulative GPA from an earlier GPA and its credits, plus a “what do I need?” target calculator.
- Courses saved in your browser only, a Clear all button, and keyboard-friendly row entry.
Tips and good to know
- Check your school’s own scale. Some give A+ 4.3, some cap it at 4.0, and some use different percentage cut-offs. Your transcript or student handbook will say.
- Pass/fail and withdrawn courses usually don’t count towards a GPA. Leave them out, or leave their grade blank and they are ignored.
- For a cumulative GPA, use the credits your earlier GPA was based on, not the total credits you have earned, if the two differ because of pass/fail classes.
- UK universities often weight final-year modules more heavily and have their own borderline rules. Enter one year at a time to see each year’s average, and treat the class as a guide.
- If the target card says a goal is not reachable, try spreading it over more credits. It shows exactly what average you would need.
Frequently asked questions
Are my grades uploaded or shared?
No. Everything is worked out by your browser on your own device. Your courses are saved in this browser’s local storage so they are there next time, and Clear all removes them.
Is it free? Are there any limits?
Yes, it is free with no sign-up and no limit on courses or terms.
Does it work on a phone, iPhone or offline?
Yes. It works in Safari on iPhone and in any modern browser on Android, tablets and computers. On a phone each course becomes a small card that is easy to fill in. Once loaded, it works without a connection.
How is GPA calculated?
Each grade is turned into points (an A is 4, a B+ is 3.3 and so on), multiplied by the course’s credits, added up, and divided by the total credits. That is why a high grade in a big course lifts your GPA more than one in a small course.
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, usually 0.5 for Honours and 1.0 for AP or IB, so the top possible is 5.0. Colleges often look at both, which is why both are shown.
How do I estimate my UK degree classification?
Choose “UK degree class”, type each module’s mark and credits, and the calculator finds the credit-weighted average: 70 or above points to a First, 60 to a 2:1, 50 to a 2:2 and 40 to a Third. Your university’s year weightings and borderline rules decide the final class.
Why does the target calculator say “Not reachable”?
Because even top marks in every remaining credit would not lift your overall average to the target. It shows the average you would need, so you can see how far off it is.
