Turn letter grades and credits into a GPA.
How to use GPA Calculator
GPA Calculator: Calculate your grade point average from letter grades and credits. It is built for speed and privacy: open the page and start, with no account required.
GPA Calculator is straightforward to use. The output is produced by standard arithmetic applied only to the numbers you type, so it updates the instant you change an input and never depends on a server. Because the work happens locally, there is nothing to install and no waiting on a network.
Open GPA Calculator on toolpermarket. The tool loads instantly and runs entirely in your browser, so you can begin right away without creating an account.
In the Course credits field, enter the credit weight of each course. Higher-credit classes move the GPA more.
In the Grade field, enter the grade points, usually 4.0 scale. Map A to 4, B to 3, and so on before entering.
Press Calculate to compute the result. The output appears immediately below the form, and you can change any input and run it again as many times as you like.
Read the result and use it as needed. If anything looks off, double-check your inputs and run it again — the calculation is local and instant, so experimenting costs nothing.
Worked example. Two courses — an A (4 credits) and a B (2 credits) — average to a GPA of about 3.67 weighted by credits.

Frequently asked questions
Why is my GPA not just the average of my grades?
Because courses carry different credit weights. A 4-credit class counts twice as much as a 2-credit one, so the GPA multiplies each grade by its credits, sums them, then divides by total credits. That weighted figure is what transcripts report.
What scale should I use for the grades?
The common 4.0 scale: A is 4, B is 3, C is 2, D is 1, F is 0, with plus and minus variants shaving or adding a third. Enter the points, not the letters, and the tool weights them by credit.
Does this match my school exactly?
It uses the standard weighted formula, but some institutions tweak plus-minus values or treat pass-fail differently. The result is a faithful standard GPA; if your school has a custom policy, apply that nuance to the grade points before entering them.
How accurate is GPA Calculator?
GPA Calculator uses the same arithmetic your operating system and spreadsheet use, so the result is as precise as the numbers you enter. It does not round or estimate unless a field is explicitly a rounded display value, and you can recompute any time to double-check.
Is my data sent to a server when I use GPA Calculator?
No. GPA Calculator runs completely inside your browser. Anything you type, paste, or upload stays on your device and is never transmitted to a server, stored in a database, or shared with a third party. You can even use it offline once the page has loaded, and closing the tab erases the session.
Does GPA Calculator work on phones and tablets?
Yes. The layout is fully responsive, so GPA Calculator behaves the same on a phone, tablet, or desktop — the form reflows to fit the screen and the buttons stay easy to tap. There is no app to install; just open the page in any modern browser and it works.
Is GPA Calculator free, and do I need an account?
GPA Calculator is free to use with no account, no sign-up, and no usage limits. It is part of toolpermarket, a matrix of private, browser-based utilities built for everyday tasks, so you can return as often as you like without registering.
