GPACalc

GPACalc is a free browser-based GPA and CGPA calculator for university and polytechnic students. It supports both the 4.0 and 4.5 grading scales, which matters for students moving between institutions that use different conventions. When courses carry different credit hours, weighted GPA mode assigns each grade the correct weight instead of treating every course as equal, so the result matches what a registrar calculates. The tool also converts between CGPA and GPA, useful when applying to programmes that ask for one figure while your transcript reports the other. You can run what-if checks to see how a target grade in a remaining course would move the overall average. Everything runs in the browser: no account, no signup, no data leaves the device. The interface updates the running GPA as courses are added or removed and shows each course contribution. It works on phones and laptops, loads in under a second, and needs no installation. Being free and unauthenticated makes it practical for advisors and tutors who need a quick reliable calculation during a conversation.
