Calculate your semester GPA and updated CGPA using your own university's real grading system — its actual grade points, credit weighting, rounding, and CGPA formula. Not a generic per-country formula.
283 universities across 43 countries, each with its own grading configuration built from that university's published policy and linked back to the source.

Every university calculates GPA differently, so pick your country and university above to load the right grading scale.
Grading is set institution by institution, not country by country. Among the 283 universities on this site there are 69 distinct grading scales, and universities that share a scale still differ underneath it: in whether plus and minus grades exist, in which marks earn credit without counting toward the average, in whether a failed course is scored as zero or excluded, and in whether the final number is rounded or simply cut off.
That last detail catches people out more than any other. A university that truncates to two decimal places records a calculated 3.4989 as 3.49, not 3.50 — which is the difference between clearing a scholarship threshold and missing it. A generic calculator that rounds the usual way will tell you the opposite.
So GPAWorld keeps one configuration per university and never falls back to a national average. Pick your university and the calculator loads its grade table, its credit rules, and its rounding.
The method is the same everywhere; only the numbers change. If you want to check the calculator's work:
Example. Calculus, 4 credits, A (4.0) → 16.0. History, 3 credits, B+ (3.3) → 9.9. Physics, 3 credits, B (3.0) → 9.0. Quality points 34.9 ÷ 10 credits = 3.49 semester GPA.
To roll that into your CGPA, multiply your current CGPA by your completed credits, add this semester's quality points, and divide by the new credit total. The guides walk through each step in more detail.
The scales below are the ones actually used by the universities covered here — a reminder of how little a bare GPA number means without knowing the scale behind it.
| Scale | Universities | Where |
|---|---|---|
| 4.00 GPA scale | 74 | Bahrain, Canada, Egypt +18 more |
| 4.30 GPA scale | 19 | Canada, Hong Kong, Japan +4 more |
| Austrian 1-5 numeric grade scale | 13 | Austria |
| Italian 18-30 exam grade scale | 13 | Italy |
| Spanish 0-10 numeric grade scale | 11 | Spain |
| Portuguese 0-20 numeric grade scale | 10 | Portugal |
| 7-point GPA scale | 9 | Australia |
| 0-20 Belgian numeric grade scale | 9 | Belgium |
Every university here has its own configuration file describing its grade codes, the points attached to them, which grades earn credit, how pass/fail and repeated courses are treated, and how the final number is rounded. One calculation engine reads those files — there is no per-country logic anywhere in the code, which is what stops one university's rules from leaking into another's result.
Each configuration records the official policy page it was built from and the date it was last checked. Both appear on the university's page, alongside the judgement calls made where a published policy was ambiguous. Where a university does not publish a machine-applicable rule — repeat-course replacement is the usual case — the page says so instead of inventing one.

Because the numbers behind the letters are set by each university, not by a national standard. One school may award 4.0 for an A and 3.7 for an A−; another awards 4.3 for an A+ and has no minus grades at all; a third grades out of 10, or out of 30, or on a scale where 1.0 is the best mark. Feed the same transcript into a generic calculator and it will confidently return a number your registrar would not recognise.
Multiply each course's grade points by its credit hours to get quality points, add up the quality points, add up the credit hours, then divide the first total by the second. That credit weighting is the part hand calculations usually get wrong — a 4-credit course moves your average twice as much as a 2-credit one.
GPA normally means one semester or term. CGPA (cumulative GPA) covers every course you have completed so far and is the figure that appears on your transcript. GPAWorld shows both: your semester result, and where your cumulative average lands once this semester is added to it.
No. Enter your current CGPA and the number of credit hours you have already completed, then just add this semester's courses. Those two numbers carry all the history the calculation needs.
It is free, and there is no account to create. The calculation runs in your browser as you type — your grades are not sent to a server or saved to your profile, because there is no profile.
No. GPAWorld is an independent tool and is not affiliated with or endorsed by any university. Each grading configuration is built from that university's own published policy, and every university page links to the sources used and the date they were last checked, so you can verify any number yourself. Your registrar's record is always the authority.
Yes. Universities are added once their grading policy has been read from an official source and encoded, so nothing goes live as a guess. Send the university name and a link to its published grading scale through the contact page and it will go on the list.
Open your university's dedicated page for its exact grading scale, a plain-language explanation of its formula, worked examples, the mistakes its rules most often cause, and an FAQ — each page is a ready-to-use calculator preloaded with that university's own rules.
