| Course | Credits | Level | Base points | Weighted points | Weighted quality |
|---|
Compare this result with your school's official calculation
Grade cutoffs, repeats, excluded courses, weighting caps, and rounding can change the transcript GPA.
Calculation policy
Every assumption is visible and adjustable
A useful GPA calculator must show its formula and avoid presenting one grading policy as universal.
Convert each grade
Letter grades, percentages, or direct inputs become base grade points from 0.00 to 4.00.
Apply course-level boosts
Regular courses receive no boost. Honors and AP/IB additions follow your selected policy.
Weight by credits
Each point value is multiplied by credits; total quality points are divided by total credits.

Why calculated and reported GPAs can differ
College Board notes that schools use different grading scales and colleges may recalculate GPA.
School rules differ
Plus/minus points, grade cutoffs, credits, repeat policies, and weighting additions are not universal.
Course inclusion differs
A school or college may include every course, focus on academic core subjects, or exclude selected electives.
Colleges may recalculate
Admission offices can normalize records using their own methodology, so do not relabel this estimate as an official GPA.

Answers about weighted GPA, credits, percentage conversion, cumulative projections, and official reporting.
How is GPA calculated?
For each course, multiply grade points by course credits to get quality points. Add quality points, then divide by total attempted credits. When every course has equal credit, this is the same as averaging the course grade points.
What is the difference between weighted and unweighted GPA?
Unweighted GPA keeps base course points capped at 4.0. A weighted policy adds selected points for advanced courses such as Honors, AP, or IB. The size of those additions varies by school, so this calculator makes them visible and editable.
Does an A+ count as more than 4.0?
Not under this calculator's base 4.0 scale: A+ and A both receive 4.0 before course-level weighting. Some institutions use a different plus/minus table, so compare the result with your official policy.
How are percentage grades converted?
The percentage option uses a common plus/minus conversion: 93+ is 4.0, 90–92.9 is 3.7, 87–89.9 is 3.3, continuing through 60–62.9 as 0.7 and below 60 as 0. Schools use different cutoffs; use direct base points if yours differs.
What should I enter for course credits?
Use the attempted credit or unit value shown by your school. A full-year class might be 1.0 while a semester class might be 0.5, but conventions vary. The relative values matter because higher-credit courses affect the GPA more.
How does the cumulative GPA projection work?
The calculator converts your current cumulative GPA and completed credits into prior quality points, adds the entered term, and divides by all credits. The current GPA must be on the same weighted or unweighted scale selected for the term.
Why can my school's GPA differ from this result?
Schools may use different grade cutoffs, repeat-course rules, excluded classes, credit units, weighting caps, or rounding. Colleges may also recalculate high school GPA using selected academic courses. Your transcript remains authoritative.
Does this GPA predict admission or scholarship eligibility?
No. A calculated GPA does not represent an admission probability, class rank, or scholarship decision. Verify each institution's current academic and testing policies directly.
