Cumulative GPA (Optional)
Academic Standing
You are currently calculating a Weighted GPA. Honors courses grant a +0.5 multiplier, and AP/College courses grant +1.0.
What Is a GPA Calculator?
A GPA calculator converts your letter grades into quality points, weights them by credit hours, and divides by total credits attempted — giving you the same number that appears on your official transcript without waiting for grades to post.
This tool supports both the standard unweighted 4.0 scale used by most colleges and the weighted 5.0 scale used by many high schools for Honors and AP courses. It also lets you layer in your prior cumulative GPA to project how your current semester will move your overall average.
How to Calculate Your GPA
Who Is This For?
- →Students checking their GPA before applying to grad school or scholarships — know your number before you submit an application, not after.
- →International students converting letter grades to the 4.0 scale — verify how your home country grading maps to the US standard before applying to US institutions.
- →Students on academic probation tracking what grades they need to recover — use the cumulative GPA field to reverse-engineer the minimum semester average needed to return to good standing.
Key Benefits
- ✓Runs in your browser. Your grades never leave your device — nothing is stored or transmitted.
- ✓Completely free. No subscription, no paywall, no account required.
- ✓No account needed. Works instantly — open the page and start calculating.
- ✓Supports both weighted and unweighted scales. Switch between 4.0 and 5.0 systems with one toggle — essential for high school students with AP or Honors courses who need to see both figures.
Common GPA Mistakes
- ✗Averaging letter grades instead of quality points — a simple average of A, B, C gives 3.0 only if the courses have equal credit hours; unequal credits require weighted averaging.
- ✗Confusing weighted and unweighted GPA when reporting to colleges — schools that recalculate GPAs strip honors and AP bonuses, so knowing your unweighted number is essential.
- ✗Excluding repeated courses — most institutions replace the original grade when you retake a course, but some average both; verify your school's policy before calculating.
- ✗Using a 4.0 cutoff for programs that require a 3.5 or higher — calculating cumulative GPA mid-semester lets you catch eligibility issues before final grades post.
GPA connects directly to other academic calculations — use our Percentage Calculator to convert between percentage scores and letter grades, or the Fraction Calculator for precise credit-hour weighting when courses have non-standard unit values.

Common Use Cases
Grad school application prep. Most programs list a minimum GPA cutoff. Run your current GPA and then model what grades this semester would produce to see if you'll hit the threshold before you apply.
Scholarship eligibility checks. Many scholarships require a minimum 3.0 or 3.5 GPA to renew. Track your semester-by-semester GPA to stay on top of eligibility requirements without surprises at renewal time.
Academic recovery planning. If you're on probation, use the cumulative GPA field to calculate exactly what semester average you need this term to bring your overall GPA back above 2.0.
High school college applications. Use the weighted scale to see your GPA the way your high school reports it, and the unweighted scale to see how colleges may recalculate it when comparing applicants.
Unweighted GPA (4.0 Scale)
An Unweighted GPA is the traditional university standard. In this system, all classes are treated equally regardless of their difficulty level.
An "A" grade in standard physical education is worth exactly the same 4.0 points as an "A" in organic chemistry. This scale maxes out at a hard ceiling of 4.0. College admissions officers frequently recalculate applicants' transcripts back to an unweighted standard to level the playing field across different high school districts.
Weighted GPA (5.0 Scale)
A Weighted GPA system was created to reward students who challenge themselves with tougher curriculums.
When the "Weighted" toggle is activated in our calculator, it mimics standard high school bonus scaling. Completing an Honors tier class grants a +0.5 quality point boost (an 'A' is worth 4.5). Completing a collegiate tier course, such as Advanced Placement (AP) or International Baccalaureate (IB), grants a +1.0 boost, meaning an A generates 5.0 points.
