GPAConverter is a free set of six calculators built for students. You can calculate a grade from exam marks, work out a credit-weighted CGPA, find the score you need on a final exam, convert GPA to percentage and back, plan study hours before an exam, and check your attendance against a required percentage. Each calculator shows the formula behind its result, so you can see how the number was reached.

All six calculators are free, and you do not need an account or sign-up to use them. The numbers you enter are processed in your browser and are not saved to our servers. Like most websites, we may use basic analytics and cookies to understand how the site is used, and our Privacy Policy explains how.

GPA usually summarizes your grades for a single term, while CGPA (cumulative GPA) combines grades and credit hours from several terms into one running average. In your first term the two numbers are the same. After that, CGPA moves more slowly because it also includes your earlier results. Some institutions use other labels such as SGPA, so check how your own school defines each term.

CGPA is credit weighted. Each subject's grade point is multiplied by its credit hours, those weighted points are added together, and the total is divided by the total credit hours. A 4-credit course therefore counts for more than a 1-credit course, even when the grades are identical. The Multi-Subject CGPA Calculator does these steps for you, and can also combine a previous CGPA with your latest semester.

The GPA to Percentage Converter uses a proportional formula:

For example, a 3.2 GPA on a 4.0 scale gives 80%. This is a mathematical estimate. Many institutions publish their own conversion tables or rules, and credential evaluators may use different methods, so the result may not match an official equivalency. When the number is needed for an application, use the method your institution or the receiving organization asks for.

The GPA to Percentage Converter supports ten scales: 4.0, 4.3, 4.5, 5.0, 6.0, 7.0, 9.0, 10.0, 12.0, and 20.0. The Multi-Subject CGPA Calculator offers 4.0, 4.3, 5.0, and 10.0 presets, plus a custom option where you enter your own grade points. A supported scale does not mean every school in a country uses it, so confirm your institution's scale before you calculate.

Treat them as planning estimates rather than official records. Admissions offices, scholarship committees, and immigration authorities usually rely on official transcripts and their own evaluation rules. The calculators can help you understand where you stand, but you should always confirm the required format and method with the organization asking for the information.

Enter your current grade, the weight of the final exam, and the overall grade you want into the Final Grade Calculator. It works backward to the score you need, and tells you when the target is already secured or out of reach. If your course has several weighted parts, such as assignments, quizzes, and a project, the full course mode lets you add each one.

Enter the classes you have attended and the classes held so far in the Attendance Percentage Calculator, then pick your required percentage, from 50% to 95% or a custom value. It shows how many more classes you can miss, or how many you need to attend to recover, and the what-if option lets you test future scenarios. Requirements differ between institutions, so check your own attendance policy.

The readiness score in the Study Hours Calculator compares the learning time in your plan with a recommended baseline for the topics you entered. It is a planning indicator, not a prediction of your exam result. A lower score usually means your available time is short compared with your topic list, which is useful to know early, while there is still time to adjust the plan.

Schools differ in grading scales, rounding rules, how repeated courses are treated, and how credits are weighted. A calculator applies a standard formula to the numbers you enter, so differences are possible. Check that you selected the right scale, entered the correct credits and grades, and compare the result with your institution's published method.
