Free GPA & CGPA Calculator
Add your modules, select grades, and get your semester GPA instantly. Free — no account required.
Used by 2,000+ students across Sri Lankan private universities
Use this free GPA and CGPA calculator to turn university module grades and credit hours into an instant weighted result. Choose the 4.0, 4.3, or 5.0 grading scale, add every completed or planned module, and see how higher-credit courses affect your academic average. Students can use the result to review semester performance, estimate cumulative standing, prepare scholarship applications, or plan the grades needed for future study. The calculation runs entirely in your browser and updates whenever a grade, credit value, or grading scale changes. Always compare the result with your university's official regulations, especially when retakes, exclusions, or programme-specific grade points apply. Read the university GPA calculator guide for practical advising and policy checks.
How to calculate CGPA — the formula explained
Your CGPA (Cumulative Grade Point Average) is the weighted average of all your semester GPAs, where each module's credit hours act as the weight.
For example, if you scored an A (4.0) in a 3-credit module and a B+ (3.3) in a 2-credit module:
Most Sri Lankan private universities use the standard 4.0 scale. Some institutions affiliated with UK universities use a class-based system instead.
Grading scales and degree classifications
Sri Lankan private higher education institutions use several grading scales depending on their international affiliations. The most common:
- 4.0 scale — Standard at most Sri Lankan HEIs and US-affiliated programmes. A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, and so on down to F = 0.0.
- 4.3 scale — Some institutions award A+ = 4.3 for exceptional performance. The maximum possible GPA is 4.3 rather than 4.0.
- 5.0 scale — Used by some Australian-affiliated and local degree programmes. Scores are proportionally higher but the relative standing is the same.
- UK class-based system — First Class (70%+), Upper Second / 2:1 (60–69%), Lower Second / 2:2 (50–59%), Third (40–49%). Percentage-based rather than GPA-based; conversion to GPA approximations varies by institution.
Frequently asked questions
GPA (Grade Point Average) typically refers to a single semester's result. CGPA (Cumulative GPA) is the weighted average across all completed semesters, where each module's credit hours act as the weight. This calculator computes the CGPA by treating all entered modules as a single combined calculation — add modules from multiple semesters to get your cumulative result.
Yes — this is the defining characteristic of a weighted GPA. A 4-credit module contributes four times more to your GPA calculation than a 1-credit module. This is why it is strategically important to prioritise performance in high-credit core modules: a strong grade in a 4-credit module has a larger positive impact than the same grade in a 1-credit elective.
Requirements vary by institution and degree programme, but the most common thresholds for a 4.0 scale are: First Class Honour — CGPA 3.70 or above; Second Class Upper — 3.30 to 3.69; Second Class Lower — 3.00 to 3.29; Pass — 2.00 to 2.99. Always verify the specific classification boundaries with your institution's academic regulations, as thresholds can differ between programmes and affiliated universities.
Yes — simply add all modules from all semesters to the calculator. Because the formula weights each module by its credit hours, the result is your cumulative GPA across all entered modules, not an average of semester GPAs. Adding each semester's modules individually and then combining gives the same result as calculating all at once.
Policy varies by institution. Some replace the original grade with the retake grade in the GPA calculation (replacement policy); others average both attempts; and some record both grades but use only the higher one. Check your institution's academic regulations before calculating the effect of a retake. In this calculator, enter only the grade that will count toward your official GPA per your institution's policy.
