About

About the GPA Calculator

Reads a list of courses and calculates the credit-weighted GPA on a 4.0 or 5.0 weighted scale.

High school and college students use it to track a semester or cumulative GPA before it shows up on a transcript, while parents and counselors use it to double-check a reported GPA. It's one of many free calculators on Toolapt, and like every tool here, it's free to use with no sign-up and no limit on how many times you run it.

3 worked examples

01

Standard 4.0 scale

Calculus (4 credits, A-), History (3 credits, B+) and Biology (3 credits, B) give a credit-weighted GPA of 3.37 out of 10 total credits.

02

Weighted 5.0 scale

The same three courses — Calculus A-, History B+ and Biology B — score 4.37 on the 5.0 weighted scale, since each grade gets one extra point.

03

A skipped invalid row

A course list with one malformed line, like "Art" with no credits or grade, is skipped automatically and the tool reports that one row was skipped while still calculating the GPA from the valid rows.

FAQ

Frequently asked questions

Quick answers to common questions about the GPA Calculator.

What does the GPA Calculator do?

It reads a list of courses with credits and letter grades and calculates the credit-weighted grade point average, on either a 4.0 or 5.0 scale.

Is the GPA Calculator free to use?

Yes. It's free, with no sign-up, no watermark and no limit on how many times you use it.

Is my course list safe when I use this tool?

Yes. Everything you type is processed entirely on your own device — nothing is sent to a server.

What format should my course list be in?

One course per line, as Course, Credits, Grade — for example "History, 3, B+". Commas separate the three fields on each line.

What happens if a row is invalid?

It's skipped automatically, and the message above the results tells you how many rows were skipped, so you can fix and recalculate.

What's the difference between the 4.0 and 5.0 scale?

The 4.0 scale is the standard scale most schools use. The 5.0 weighted scale adds one extra point to every passing grade, commonly used to reflect the added difficulty of honors or AP-style courses.

Does it handle plus and minus grades?

Yes. The full range from A+ to F, including plus and minus grades like B- or C+, is supported on both scales.

Can I use the GPA Calculator on my phone?

Yes. The page is fully responsive and works on mobile, tablet and desktop browsers alike.
