GPACalc

GPACalc is a free, browser-based GPA and CGPA calculator built for university and polytechnic students who need to track academic performance without wrestling with spreadsheets. It supports both the 4.0 and the 4.5 grading scales, which matters for students moving between institutions that use different conventions. When courses carry different credit hours, the weighted GPA mode assigns each grade the correct weight instead of treating every course as equal, so the number it produces matches what the registrar will calculate. The tool also converts between CGPA and GPA, which is useful when applying to programmes that ask for one figure while your transcript reports the other, and when preparing applications you can run what-if checks to see how a target grade in a remaining course would move the overall average. Everything runs entirely in the browser: no account, no signup, no data leaves the device, so students can enter real transcripts without worrying about where the numbers end up. The interface updates the running GPA as courses are added or removed, shows the contribution of each course to the total, and lets you save a session locally if you want to come back later. It works on phones and laptops alike, loads in under a second, and requires no installation. Because it is free and unauthenticated, it is also practical for advisors and tutors who need a quick, reliable calculation during a conversation rather than a full student information system. GPACalc is maintained as a small focused utility: one job, done accurately, with no advertising or upsell inside the calculator itself.
