GPA Calculator Sri Lanka - University GPA

Enter each module's credit value and grade to calculate a credit-weighted semester or cumulative GPA. Check the displayed grade points against your faculty handbook before using the result for degree planning.

Grade points and degree-class rules vary by university, faculty, programme, and intake. Confirm the selected mapping, repeat rules, rounding, credit exclusions, and completion-time conditions in your own handbook.

How credit-weighted GPA is calculated

For each module, multiply its credit value by the grade point earned. Add those weighted points and divide by the total credits included in the calculation.

GPA=∑(module credit×grade point)∑included creditsGPA = \frac{\sum (\text{module credit} \times \text{grade point})}{\sum \text{included credits}}

Grade points used by this calculator

The default is a common 4.0 example matching the cited current UoM Engineering mapping. It is not a universal UGC scale. Select custom grade points when your programme handbook differs.

Worked GPA example

A 3-credit module with an A contributes 12.0 weighted points. A 2-credit module with a B+ contributes 6.6. The combined GPA is 18.6 divided by 5 credits, or 3.72.

GPA for common grade combinations

A semester of five 3-credit modules, under the default 4.0 mapping above. Because every module carries equal credit here, the GPA is simply the average of the grade points - the weighting only starts to matter when module credits differ.

This is why a single weak grade costs less than students fear, and why a weak grade in a heavy module costs more than the same grade in a light one. Four A grades and one B+ still comes to 3.86; the same four A grades with a C drops you to 3.60.

How much one module can move your GPA

The arithmetic that matters when you are deciding where to spend revision time. Across five equal modules, each one carries a fifth of the semester GPA, so moving a single module up one grade step - a B to a B+, worth 0.3 grade points - lifts the semester GPA by 0.06.

Cumulatively the effect shrinks fast. By the time you have four semesters banked, one module is a twentieth of the total, so the same one-step improvement moves the cumulative GPA by around 0.015. This is the reason early semesters matter disproportionately: they are a larger share of a smaller total, and they set the floor everything afterwards has to lift.

How to interpret the result

Use semester GPA to understand one period and cumulative GPA to track all included semesters. The optional class guide is not an award decision. For example, UoM Engineering intake 2020 onward places Second Lower at 3.00-3.29, while the official intake-2007 criteria used 2.70-3.29. Check residency, repeats, required credits, completion time, and any final-year weighting in your own handbook.

Frequently asked questions

GPA is the sum of (grade points x credits) for every included course, divided by the total included credits. The exact grade mapping and inclusion rules come from your programme handbook.

No. Grade points, repeated-module treatment, rounding, exclusions, and degree-class thresholds can differ by university, faculty, programme, and intake. Always check your current handbook.

Commonly 3.70 and above, but the threshold and the conditions attached to it are set by each university and faculty, not nationally. Most also require a minimum number of credits taken at the institution, limits on repeated modules, and completion within a set time. Your programme handbook is the only authority on this.

Multiply each module's credit value by the grade point for the grade you earned, add all of those together, then divide by the total credits counted. For a 3-credit module with an A worth 4.0 and a 2-credit module with a B+ worth 3.3, that is (3 x 4.0) + (2 x 3.3) = 18.6, divided by 5 credits, giving 3.72.

SGPA covers a single semester; CGPA covers every semester counted so far. CGPA is not the average of your SGPAs unless each semester carried identical credits - it is credit-weighted across all modules, so a heavier semester pulls harder.

That depends on your university's rules, and the variation is wide. Some replace the original grade, some average the attempts, and many cap the grade a repeat can earn. Because the treatment differs, this calculator does not assume one - enter whichever grade your faculty actually counts.

Less than most students expect, and less the further into the degree you are. Across five equally weighted modules in one semester, dropping a single module from an A to a C costs 0.40 on that semester's GPA. Spread across four semesters of banked credits, the same grade moves the cumulative figure by roughly a tenth of that.

Most use a 4.0 scale, but the grade-to-point mapping differs between universities and sometimes between faculties or intakes at the same university. Whether an A+ is worth more than an A, and where the boundaries fall, are both local decisions. Use the custom grade-point option if your handbook does not match the default shown here.

A credit is the weight a module carries in the average. A 4-credit module influences your GPA twice as much as a 2-credit one with the same grade, which is why a poor result in a heavy core module hurts far more than the same result in a light elective.

You can move it, but the room narrows as credits accumulate, because each new module is a smaller share of a larger total. Some programmes also weight later years more heavily in the final classification, which works in your favour. Check whether yours does, and use the target GPA tool to see what the remaining semesters would actually have to deliver.
