What the GPA Calculator does
This tool turns a list of course grades and credit hours into a single grade point average on the standard 4.0 scale. It is handy for students checking where they stand before finals, anyone deciding whether to retake a class, and parents who want to double-check a report card. Because each course is weighted by its credit hours, a 4-credit lab counts more than a 1-credit elective, which is exactly how most schools figure GPA.
How to use it
- Enter your grade values for each course in the grades field. Use the point value your school assigns, such as 4 for an A, 3 for a B, and so on, separated by commas.
- Enter the matching credit hours in the credits field, in the same order as your grades.
- Your GPA appears in the result card right away, with no button to press. Totals for credits and grade points show underneath.
- Tweak any number to test a what-if, like seeing how one higher grade lifts your average.
Why calculate it here
Everything happens locally in your browser, so your grades never touch a server and there is nothing to sign up for. It is free, loads fast, and works the same on a phone, tablet, or laptop. The math is the plain credit-weighted formula schools use, so the number you get lines up with an official transcript as long as your inputs match.
Quick tips
Keep grades and credits in the same order, or the pairing will be off. If your school uses pluses and minuses (A- = 3.7, B+ = 3.3), enter those exact decimals for a more precise result. To get a cumulative GPA, just include every course you have taken across all your terms in one go.
Frequently asked questions
- How is GPA calculated from grades and credits?
- Each course grade is converted to grade points (for example A = 4.0, B = 3.0), then multiplied by that course's credit hours. The calculator adds up all the grade points, divides by the total credits, and shows your GPA on a 4.0 scale.
- Does this calculator support weighted GPA for AP or honors classes?
- It computes a credit-weighted GPA, meaning courses with more credit hours count more toward the result. If your school adds extra points for AP or honors classes, enter those boosted grade values so they are reflected in the average.
- Is my grade data saved or sent anywhere?
- No. The calculation runs entirely in your browser and nothing is uploaded. Your grades and credits stay on your device, and they disappear when you close or refresh the page.
- Can I use it to calculate both semester and cumulative GPA?
- Yes. Enter the grades and credits for one term to get your semester GPA, or list every course you have taken to get your cumulative GPA across all terms.
