GPA Calculator
Enter your grades and credit hours to get your GPA instantly — unweighted or weighted for Honors/AP courses.
About this tool
What this tool does
Add each course you're taking (or have taken), pick a letter grade and how many credit hours it's worth, and this calculates your GPA on the standard 4.0 scale. Turn on weighted mode to automatically add the usual Honors (+0.5) and AP/IB (+1.0) bonus per course before averaging, matching how most US high schools calculate weighted GPA.
Who it's for
High school students tracking their GPA for college applications, college students checking where they stand for a semester, or anyone estimating how a final grade will move their overall average before the term ends.
How to use it
- Add a row for each course — name is optional, but grade and credit hours are used in the calculation.
- Pick the letter grade from the dropdown and enter the credit hours (most courses are 3-5).
- If your school weights GPA for Honors and AP/IB classes, check "Weighted GPA" and set each course's type.
- Your cumulative GPA updates instantly as you add, edit, or remove courses.
Real-world examples
Three courses — an A in a 3-credit class, a B+ in another 3-credit class, and an A- in a 4-credit class — averages out to roughly a 3.63 unweighted GPA. Mark that A- course as AP and turn on weighted mode, and the same set of grades produces a higher weighted GPA that reflects the extra rigor.
Frequently asked questions
What's the difference between weighted and unweighted GPA?
Unweighted GPA treats every class the same regardless of difficulty, capped at 4.0. Weighted GPA gives extra points for harder classes like Honors and AP/IB, which is why a weighted GPA can go above 4.0.
How do you calculate GPA by hand?
Multiply each course's grade points by its credit hours, add those up, then divide by the total credit hours. This tool does exactly that automatically as you enter courses.
Does a plus or minus grade change my GPA?
Yes — most schools use a +/- scale where an A- is worth 3.7 instead of a full 4.0, and a B+ is 3.3 instead of 3.0. This calculator uses that standard 13-point scale.
How much does one AP class affect my weighted GPA?
It depends on your total credit load — a single AP course adds up to 1.0 grade point for just that course's credit hours, so its overall impact on your cumulative GPA depends on how many total credits you're averaging across.
Can I use this for college GPA too?
Yes — the standard 4.0 unweighted scale is the same one most US colleges use. Just note that some colleges weight Honors/AP differently or not at all, so check your specific school's policy for official calculations.
