How the University of Lisbon GPA formula works

University of Lisbon converts every graded course into quality points by multiplying the grade's point value by the course's credit hours. Your semester GPA is the total quality points divided by the total credit hours that count toward the GPA, and the result is rounded to the nearest 2 decimal places. Points run from 0.0 up to 20.0, so a higher average is a better result. The scale has no plus/minus steps, so every grade in a band is worth exactly the same number of points.

What gets left out of the average

0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and 3 others carry no point value at University of Lisbon, so a course marked with one of them drops out of the division entirely — it changes neither the top nor the bottom of the fraction. P still earns credit toward your degree while staying out of the GPA, which is why your credit total can climb in a semester where your GPA barely moves.

How this semester rolls into your CGPA

ULisboa official sources state grades use the national 0-20 scale, credits are awarded with a passing grade of at least 10, and ISEG master regulations calculate the final syllabus grade as an ECTS-weighted arithmetic mean. In practice that means your existing CGPA is turned back into quality points by multiplying it by your completed credits, this semester's quality points are added on, and the total is divided by your new credit total. Both the semester and the cumulative figures are rounded to the nearest 2 decimal places. Repeat handling is not published as a rule this calculator can apply automatically, so retaken courses need to be checked against the current catalog.

How University of Lisbon compares with other Portugal universities

All 10 Portugal universities covered here — including NOVA University Lisbon, Portuguese Catholic University, University of Algarve and 6 others — publish the same Portuguese 0-20 numeric grade scale. On the published rules this calculator uses, University of Lisbon's grading is equivalent to theirs: the same point values, the same rounding, and the same repeat policy. Where they genuinely differ is in the source material behind each configuration and the caveats recorded with it, which are listed further down this page. The pass mark on this scale is 10.

A GPA only means something alongside the scale it was calculated on, which is why comparing raw numbers between institutions — even neighbouring ones — is unreliable. See the Portugal comparison table for every university covered there side by side.

Converting this GPA to a 4.0 scale

University of Lisbon does not grade on the US 4.0 scale. Its scale runs to 20.0 rather than 4.0, with 11 point values in use and 10 as the lowest passing mark. There is no single correct formula for converting that into a 4.0 GPA, and GPAWorld deliberately does not publish one: every graduate school, employer and credential evaluator applies its own conversion table, and a number invented here could cost you an application. Calculate your GPA on this page using the real University of Lisbon scale, then let the institution you are applying to convert it with their table.

Worked examples

Each example below is run through the same engine the calculator uses, so the numbers show University of Lisbon's own rounding.

A typical graded semester

A student sitting at 14.40 after 60 completed credits takes 3 courses worth 3 credits each.

Core course3 credits × 20 (20.0 points)
Elective3 credits × 18 (18.0 points)
Lab or seminar3 credits × 16 (16.0 points)

Semester GPA 18.00 · Updated CGPA 14.87

The semester total is 162 quality points over 9 counted credits. Because the cumulative average now spans 69 credits, one semester moves it only a little — this is why a CGPA gets harder to shift the further into a degree you are.

Adding a course graded P

The same student adds a fourth 3-credit course graded P (Pass / approved).

Core course3 credits × 20 (20.0 points)
Elective3 credits × 18 (18.0 points)
Lab or seminar3 credits × 16 (16.0 points)
Pass / approved course3 credits × P (no grade points)

Semester GPA 18.00 · Updated CGPA 14.87

The semester GPA is unchanged at 18.00. P carries no grade points at University of Lisbon, so the course is removed from both sides of the division — even though the credit still counts toward the degree. Students often expect a fourth course to move the average and are surprised when it does not.

What this semester does to your CGPA

A student with a 14.40 CGPA after 60 credits takes 4 courses worth 3 credits each (12 credits in total). Here is where that CGPA lands if every course comes back at the same grade — calculated with the University of Lisbon scale and rounding.

Projected University of Lisbon CGPA after a 12-credit semester
If every course is	Semester GPA	New CGPA	Movement
20 (20.0)	20.00	15.33	+0.93 (better)
18 (18.0)	18.00	15.00	+0.60 (better)
16 (16.0)	16.00	14.67	+0.27 (better)
14 (14.0)	14.00	14.33	−0.07 (worse)

Common mistakes when calculating your University of Lisbon GPA

These are the places where the University of Lisbon rules differ from what most students assume, and where a hand calculation usually goes wrong.

Counting P courses in the average
These earn credit at University of Lisbon but carry no grade points, so they belong in your credit total and nowhere near the GPA division. Including them is one of the most common reasons a hand-calculated GPA comes out wrong.
Borrowing plus/minus values from another university
The University of Lisbon table has no plus or minus steps — every grade in a band is worth the same points. Intermediate values like 3.3 or 3.7 do not exist on this scale.
Averaging the grades instead of weighting them
A course worth twice the credits moves your GPA twice as much. Adding up your grade points and dividing by the number of courses ignores that weighting and is almost always wrong.
Expecting a 0-credit course to move the number
University of Lisbon allows them, but with no credit hours they contribute nothing to either side of the division.
Handling a retake by guesswork
Repeat handling is not published as a rule this calculator can apply automatically, so retaken courses need to be checked against the current catalog. Check the current catalog before assuming an old grade has left your record.

University of Lisbon GPA — frequently asked questions

What is a passing grade at University of Lisbon?

10 (10.0 points) is the weakest grade in the University of Lisbon table that still earns credit. Anything below it is counted in your GPA but earns no credit toward the degree. Individual programmes can set a higher minimum for courses in your major, so check your programme handbook as well.

What is the best GPA you can get at University of Lisbon?

20.0 on the Portuguese 0-20 numeric grade scale, which you reach by earning 20 (20.0 points) in every course that counts toward the GPA.

Does University of Lisbon round GPA up?

The cumulative average is rounded to the nearest 2 decimal places, and the semester average is rounded to the nearest 2 decimal places. That is ordinary rounding, so a result sitting exactly half a step along goes up.

Is this a generic Portugal GPA formula?

No. This page is generated from the grading configuration for University of Lisbon alone — its 11 point values, its standard rounding, and its own rules for pass/fail and repeated courses. Other universities in Portugal routinely use different point values or a different scale entirely, so the same grades can produce a different GPA elsewhere.

Do pass/fail courses affect my GPA?

No. P earns credit at University of Lisbon without carrying grade points, so it is excluded from the GPA division entirely. Your completed-credit total goes up while the average stays where it was.

Which grades are excluded from the University of Lisbon GPA?

0 (Fail / not passed), 1 (Fail / not passed), 2 (Fail / not passed), 3 (Fail / not passed), 4 (Fail / not passed), 5 (Fail / not passed), 6 (Fail / not passed), 7 (Fail / not passed), 8 (Fail / not passed), 9 (Fail / not passed), P (Pass / approved), F (Fail / not passed), and NP (No show / not assessed) carry no grade points and are left out of the average. Of those, P still earn credit toward the degree.

What happens to my GPA if I repeat a course?

Repeat handling is not published as a rule this calculator can apply automatically, so retaken courses need to be checked against the current catalog.

How much does one semester change my cumulative GPA?

Your CGPA is weighted by every credit you have already completed, so a single semester moves it less the further along you are. Fifteen credits added to sixty already completed is a fifth of your record; the same fifteen added to a hundred and twenty is an eighth of it. Use the calculator at the top of this page with your real completed-credit total rather than estimating the movement.

What percentage is a 20 at University of Lisbon?

20 covers 20–20% and is worth 20.0 grade points. The full percentage-to-grade table for all 11 graded bands is published on this page.

Is this calculator official?

No. GPAWorld is an independent tool and is not affiliated with or endorsed by University of Lisbon. The grading data on this page was taken from ULisboa - ECTS and Evaluation Systems, T?cnico ULisboa - ECTS Grading System, and ISEG ULisboa - Regulation for Masters and last verified on 2026-07-21; every source is linked on this page so you can check it yourself. Your registrar's record is always the authority.

Notes on this university's data

Judgement calls and caveats recorded when this grading configuration was built from the official sources. They are published so you can see exactly what the calculator assumes.

University of Lisbon has its own official grading information and is not treated as a generic Portugal formula.
ULisboa uses the Portuguese 0-20 national grading scale and requires at least 10 to earn credits.
The ISEG master regulation states the weighting unit is the number of ECTS assigned to each course unit.
Failed numeric grades below 10 are excluded because the official degree-average sources calculate final averages from passed curricular units / credits obtained for the degree.
Retake/repeated-course handling is manual-review because the official sources used here do not provide a complete machine-calculable replacement rule.
No logo was added because official reuse rights were not confirmed.
