Combine every semester into one cumulative GPA, or see how a new term will move your overall average — calculated in your browser. Runs entirely in your browser — your numbers never leave this device.
| Grade | Grade points | Credits | Quality points |
|---|---|---|---|
| A | 4.00 | 3 | 12 |
| B+ | 3.30 | 3 | 9.9 |
Your cumulative GPA is not the simple average of your semester GPAs, unless every semester carried the same number of credits. Each semester's GPA is weighted by how many credit hours you took that term: multiply each semester GPA by its credits to recover its grade points, add them all together, and divide by your total credits.
You can use this in two ways. Enter past semesters to reconstruct your current cumulative GPA, or add a planned semester with an expected GPA to preview where your cumulative average will land. The underlying grades still use the standard 4.0 scale (A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, down to F = 0.0).
Because the denominator grows every term, your cumulative GPA moves more slowly over time. A first-year student can shift it quickly; a senior with 100 credits banked will see even a perfect semester move the cumulative figure by only a few hundredths. This tool shows the honest maths — it does not inflate what one good term can do.
A simple average only works when every semester has identical credit hours. A 3.8 earned over 18 credits should count for more than a 3.2 earned over 12 credits. Weighting each semester by its credits is the method registrars use, and it is what this calculator does.
Yes. Enter your current cumulative GPA with your total completed credits as one row, then add each future or missing semester as its own row. The maths is identical, because your cumulative GPA multiplied by your credits recovers your total grade points exactly.
It depends on how many credits you already have. With 30 credits banked, a 15-credit semester at 4.0 can lift a 3.2 cumulative to about 3.47. With 90 credits banked, that same perfect semester lifts it only to about 3.31, because the new points are divided by a much larger total.
Yes. This calculator runs 100% in your browser and stores nothing — no account, no upload, and no record of your GPAs or semesters is kept anywhere. Everything is calculated on your device and gone when you close the page.
Usually not. Most colleges include only courses taken at their own institution in the cumulative GPA, even though transfer credits count toward your degree total. Check your school's policy, and if transfer grades are excluded there, leave them out here too so the estimate matches your transcript.
