GPA & Grade Calculator
A grade calculator with four switchable modes: GPA on the 4.0 scale, CGPA to percentage, a weighted class grade, and what you still need on the final.

9.5 is CBSE's indicative rule. Many universities use 10, or publish a table with no single multiplier behind it.
How to use
- Choose what you are working out first. Only one mode is on screen at a time, so if the fields aren't what you expected, you're in the wrong one.
- Fill it in and read the figure at the top, with the facts under it. Nothing to submit and no Calculate button anywhere. Add course and Add item append a row, the × at the end of a row removes it, and Copy the numbers takes the figure and its facts as text.
About this tool
Pick what you are working out along the top and the grade calculator changes what it asks for. GPA wants a list of courses with their letter grades and credit hours. CGPA → % wants one number and a multiplier. Class grade wants your graded work with the weight each piece carries, and it also solves for the mark you need on the final. % → letter is a lookup against the whole scale, drawn under the answer.
The GPA side runs on the standard American 4.0 points. Every option in the grade dropdown says its points, so A+ · 4.0 and A · 4.0 sit side by side and the tie is plain where you choose. The ladder carries on down to F at zero, thirteen letters in all, with no 4.3 for an A+ because plenty of registrars don't award one. Each course gets multiplied by its credit hours before the average is taken, which is why a four-credit class moves the figure about twice as hard as a two-credit one. The page opens on a sample semester (Organic Chemistry A− over 4 credits, Statistics B+, World History A, Spanish II B) that averages 3.48 over 14 credits.
Class grade is a weighted average of exactly what you type in. The sample has a midterm of 78 worth 25, labs at 91 worth 20 and quizzes at 84 worth 15, so you stand at 83.83%. With the final worth 40 and a target of 85, the sentence under the figure says you need 86.75% on the final. Every figure redraws on the keystroke, and the × at the end of a row throws that row away.
How it does that last sum is worth understanding, because it can flatter you. It treats the weights you entered plus the final's weight as the whole course. Give it 60 points of coursework and a 30-point final and it solves as though the course were 90 points rather than 100, so the sentence turns amber and names the 10 points that are missing. The same sentence changes its tone with the outcome: it warns when even a perfect final falls short of the target, and it says so plainly when the target is already secured whatever you score.
CGPA → % multiplies and rounds to two places, so the 8.2 it opens with becomes 77.90%. The 9.5 multiplier is the CBSE rule and it's an editable field, since a lot of universities use 10 or publish a conversion table with no single multiplier behind it. A CGPA above 10, or one that multiplies past 100%, is refused at its field rather than printed. The last mode takes a percentage and hands back the letter and its points: type 88 and you get B+ and 3.3, with the letters either side and how far away they are.
Good to know
- The 4.0 points and the letter bands are American conventions, and the dropdown is fixed at thirteen letters with fixed values. An A starts at 93% here and an F is anything under 60. If your school hands an A+ a 4.3, or draws the A line at 95, there is no field to say so, and your registrar's table beats anything on this page. Pass/fail credits, grade replacement and honours weighting aren't modelled at all.
- Nothing is stored on this device. The page address carries the mode, every row and every field instead, so bookmark it or send the link to keep a term's courses; a twelve-course semester is about 500 characters.
Things students ask
What do I need on my final to get an A?
Switch to Class grade and enter every graded thing so far, each with its score and the weight it carries. Then set Final weight to whatever the exam is worth and Target overall to your A line, which is 90 at a lot of schools and 93 at others. The sentence under the figure carries the mark you need. If it comes back above 100 the page tells you outright that a perfect paper still wouldn't reach the target, and where that perfect paper would leave you.
My university multiplies CGPA by 10. Can I change the 9.5?
The Multiplier box sits right next to the CGPA field. Type 10 over the 9.5 and an 8.0 reads 80.00% instead of 76.00%. The 9.5 default comes from the CBSE formula, which is the most widely quoted rule in India, though a fair number of institutions publish their own table with no single multiplier behind it. Use whatever your handbook says.
How do I work out my cumulative GPA across every semester?
Put every course from every term into GPA mode as one long list. Because each row is weighted by its credit hours, adding them all at once gives the same figure as averaging your semester GPAs by credits, and it's harder to get wrong. Total credits under the average is a decent check that you haven't dropped a course by accident.
Does an A+ count for more than an A?
No. Both sit at 4.0 in the dropdown, which is how most American 4.0 scales work. Some schools do award 4.3 for an A+, and if yours is one of them the figure this page gives you will read slightly low. There's no way to enter a 4.3 here.
Why doesn't my current grade match the one in my LMS?
Where you stand averages only the rows you typed, weighted by the weights you gave them. Enter 60 points of a 100-point course and you get your standing on those 60, which usually looks better than the gradebook figure. Most gradebooks either count ungraded work as a zero or weight by category rather than by individual item. Match the rows to your syllabus line by line and the two should agree.
