Frequently asked questions
What does Grade Calculator do?
Weighted grade across assignments and exams. The whole thing runs in your browser tab, so it is ready the moment the page finishes loading.
Is Grade Calculator free to use?
Yes. Grade Calculator is completely free on ToolMunch — no trial, no premium tier holding back the main feature, and no daily or hourly cap on how many times you can use it.
Do I need to create an account or sign up?
No. There is no account, no email address, and no login. Open Grade Calculator, do the job, and take the result — nothing is gated behind a signup form.
Are the numbers I enter sent to a server?
No. Grade Calculator runs entirely inside your browser tab, so what you type never leaves your own device. Nothing is uploaded, which means there is no copy of it on a server to worry about.

Yes. Grade Calculator runs in any modern web browser on Windows, macOS, Linux, Chromebook, Android, and iOS. There is nothing to download or install.
Can I use it as many times as I want?
