PowerSchool GPA calculator
PowerSchool calculates GPA with formulas your district sets up. Its standard weighted GPA multiplies each grade’s GPA points by the class’s credit hours, adds them up and divides by the total credits, rounded to three decimals. Its standard simple GPA averages the GPA points and ignores credits, cut off at two decimals. Honors and AP classes count for more only when your district gives them extra points. Enter your grades, credits and your district’s points to see both numbers.

How does PowerSchool calculate GPA?
PowerSchool SIS “includes four standard calculation methods: Simple, Simple Percent, Weighted, and Weighted Percent.” Districts can “modify the standard methods” or “create an unlimited number of additional calculation methods,” so the formula behind your GPA is your district’s choice. GPAs are “calculated on the fly” from the grades PowerSchool holds, and PowerSchool’s documentation gives the standard formulas as samples:
| Method | What it does | Rounding in PowerSchool’s sample |
|---|---|---|
| Weighted | Each grade’s GPA points × the class’s potential credit, added up, ÷ the total potential credit | Rounded to 3 decimals |
| Simple | The average of the GPA points. Credits are not used | Truncated to 2 decimals: trunc(average(gpa_gpapoints()),2) |
| Simple Percent | The average of the percentages | The docs’ example rounds to 2 decimals: 95.5, 83.2, 67.8 and 92 average 84.625, shown as 84.63 |
| Weighted Percent | Like Weighted, with percentages in place of GPA points | Not given |
The calculator above uses the two sample formulas exactly, and shows the percent versions when every grade you type is a percentage.
Weighted GPA = sum of (GPA points × credits) ÷ sum of credits · Simple GPA = sum of GPA points ÷ number of grades

Is PowerSchool GPA weighted or unweighted?
In PowerSchool’s own terms, “weighted” means credit hours count. For a weighted GPA, “the system also includes the number of credit hours students earn in each course in the GPA calculation.” For a simple GPA, “only the students’ grades are involved in the calculation, and the credit hours of each course are not referenced.” That is not the honors-weighted GPA high schools usually mean.
Honors and AP points come from grade scales. PowerSchool’s example is that “grades for AP Calculus count more towards a student’s GPA than grades for Basic Math”: the district assigns the two courses to different grade scales, and a scale can also let teachers “enter an added value for a grade that exceeds the normal grade points.” So a PowerSchool weighted GPA may or may not include honors points, depending on your district’s scales. The calculator shows both: its main numbers include the honors and AP points you set, and a note gives the numbers without them.

Where do you see your GPA in PowerSchool?
PowerSchool’s student and parent help describes two grade pages. Grades and Attendance shows current-term grades and assignment scores. Grades History notes “the course, letter grade, percentage points, citizenship grade, and credit hours” for each term. Neither page description mentions a GPA, so whether you see one in the portal or the app depends on how your district set it up. On staff pages, a school chooses which GPA appears under a student’s schedule (Weighted, Weighted Percent, Simple, Simple Percent or Total Earned Credit), and PowerSchool notes that current grades “are always calculated using the simple method.” If you can’t find a GPA, Grades History has the letters and credit hours the calculator needs.

Why hasn’t my PowerSchool GPA updated?
Because a cumulative GPA reads stored grades. PowerSchool has three calculation types:
| Type | Grades it uses |
|---|---|
| Cumulative (the default) | “Values from historical grades only,” the grades a school stores, usually after a term ends |
| Current | “The current (not stored) grades sent by the PowerSchool SIS Teacher” for the term the school sets as active |
| Projected | Historical grades plus projected ones, such as current final grades for seniors applying to college before grades are stored |
Mid-term, your cumulative GPA usually stays where it was at the end of the last stored term while your class grades move. To see where this term’s grades would take it, enter them above with your credits.

Does a retaken class replace the old grade?
With repeated course grade suppression turned on, yes. PowerSchool’s example: a student gets an F in semester 1 and a B in semester 2, and “the F will be replaced by the B meaning the F will be excluded from graduation, class rank, honor roll, and GPA calculations.” Districts can also cap the credit a repeated course earns. If your school replaces the old grade, leave it out of the calculator.

A worked example
Six classes on the plus and minus 4.0 scale, with 0.5 extra points for honors and 1.0 for AP:
| Class | Grade | Credits | GPA points |
|---|---|---|---|
| English 10 (honors) | A- | 1 | 3.7 + 0.5 = 4.2 |
| AP World History | B+ | 1 | 3.3 + 1.0 = 4.3 |
| Algebra II | B | 1 | 3.0 |
| Chemistry | A | 1 | 4.0 |
| Spanish II | C+ | 1 | 2.3 |
| PE | A | 0.5 | 4.0 |
Weighted: 4.2 + 4.3 + 3.0 + 4.0 + 2.3 + (4.0 × 0.5) = 19.8 quality points ÷ 5.5 credits = 3.600. Simple: (4.2 + 4.3 + 3.0 + 4.0 + 2.3 + 4.0) ÷ 6 = 21.8 ÷ 6 = 3.6333…, truncated to 3.63. Without the honors and AP points the same grades give 18.3 ÷ 5.5 = 3.327 weighted and 20.3 ÷ 6 = 3.383…, so 3.38 simple.
The half-credit PE class shows the difference between the two methods. The simple GPA counts its A as a full grade, so it lifts the simple number more than the weighted one.
Why your number might not match PowerSchool
- Your district wrote its own formula. Most of what follows comes from options PowerSchool gives each calculation method.
- Only some classes count. A method can be limited to certain credit types (a core-only GPA, for example), grade levels, school years or terms, and to grades flagged to count in GPA.
- One scale for everything. A method can override every class’s GPA points with a single grade scale, which can drop honors and AP points that came from separate scales.
- Different points per letter. Copy your district’s GPA points into the calculator with Edit the points.
- Added value works another way. PowerSchool’s sample value-added GPA is
average(gpa_gpapoints())+sum(gpa_addedvalue()), which adds the total of all added values to the average instead of adding points class by class. - Percentages near a cutoff. A grade scale’s Cutoff % is “the lowest percentage students can earn to receive this grade.” If you type percentages, the calculator compares them as typed. Typing the letter PowerSchool shows avoids the question.
- Rounding. Weighted rounds to three decimals and simple truncates to two in the standard formulas, so with equal credits an exact 3.329 shows as 3.329 weighted and 3.32 simple.

PowerSchool GPA calculator FAQ
Is PowerSchool GPA weighted or unweighted?
It depends on your district’s setup, and the word means something specific in PowerSchool. A PowerSchool “weighted” GPA counts each class by its credit hours, and a “simple” GPA ignores credits. Extra points for honors and AP classes come separately, from the grade scale those classes use, so a weighted GPA there may or may not include them.
How does PowerSchool calculate GPA?
With formulas your district picks. The standard weighted GPA multiplies each grade’s GPA points by the class’s potential credit, adds them up and divides by the total credit, rounded to three decimals. The standard simple GPA averages the GPA points and cuts the result off at two decimals. Districts can change both or write their own.
Why isn’t my GPA updating in PowerSchool?
A cumulative GPA uses stored grades only, and schools usually store final grades after a term ends. Until then, your in-progress grades show up in a current GPA, if your school displays one, but not in the cumulative GPA.
How do I find my GPA on PowerSchool?
PowerSchool’s student and parent help describes Grades and Attendance and Grades History, but no GPA field, so it appears only if your district set the portal up to show it. Grades History lists each term’s letter grades and credit hours, which you can enter in this calculator. Your counselor can tell you which GPA your school reports.
Does PowerSchool round GPA?
The two standard formulas differ. The weighted GPA is rounded to three decimals, so 3.32727 becomes 3.327. The simple GPA is truncated to two decimals, so 3.38333 becomes 3.38 and even 3.389 stays 3.38. Your district can change either.
Do honors and AP classes count more in PowerSchool?
Only if your district sets it up. PowerSchool’s help gives the example of AP Calculus counting more toward a GPA than Basic Math by putting the two courses on different grade scales. A scale can also let teachers enter an added value above the normal grade points.
Does a retaken class replace the old grade?
If your district uses PowerSchool’s repeated course grade suppression, yes. In PowerSchool’s example, an F in semester 1 followed by a B in semester 2 means the F is excluded from GPA, class rank, honor roll and graduation calculations. Leave the replaced grade out of the calculator.
Does this calculator send my grades anywhere?
No. The math runs in your browser. The grades, credits and class names you type are not sent to any server and are not saved, so reloading the page clears them.
For a class grade from your assignments, use the PowerSchool grade calculator. If your school reports a 100-point or weighted 5.0 GPA, the GPA scale converter puts it on the 4.0 scale, and the high school GPA calculator shows weighted and unweighted GPAs side by side. Grade calculators for other school gradebooks: Infinite Campus, Skyward, Schoology and Google Classroom. For college courses graded in Canvas, the Canvas GPA calculator turns course percentages into a GPA.
