High School GPA Calculator
Calculate your weighted high school GPA with Honors and AP/IB course bonuses.
🎓 What is the High School GPA Calculator?
The high school GPA calculator computes your weighted grade point average, adding bonus points for Honors and AP/IB course difficulty, alongside your standard unweighted GPA for direct comparison.
High schoolers use weighted GPA to see how challenging coursework affects their transcript, since many schools reward the extra difficulty of Honors and Advanced Placement or International Baccalaureate classes with bonus grade points, letting a strong performance in demanding courses push a GPA above the standard 4.0 ceiling.
A common point of confusion is that a single "GPA" number does not exist, weighted and unweighted GPA are both valid, calculated differently, and used for different purposes. Colleges may look at either or recalculate their own version entirely, which is why showing both numbers side by side is more useful than reporting just one.
This tool is useful because it lets you enter your actual course mix, regular, Honors, and AP/IB, credit hours and all, and see exactly how the weighting bonus changes your GPA compared to the unweighted baseline.

How is weighted GPA calculated?
Weighted GPA adds a bonus to each course's standard grade points based on course difficulty: +0.5 for Honors courses and +1.0 for AP or IB courses, before multiplying by credit hours and averaging. An A in an AP class contributes 5.0 grade points per credit instead of the standard 4.0.
What is the difference between weighted and unweighted GPA?
Unweighted GPA uses the standard 4.0 scale for every course regardless of difficulty. Weighted GPA adds a bonus for Honors and AP/IB courses, which is why a weighted GPA can exceed 4.0 while an unweighted GPA is always capped at 4.0.
How much bonus do AP and Honors classes add to GPA?
The most common weighting scheme adds +0.5 grade points for Honors courses and +1.0 grade points for AP or IB courses, on top of the standard letter grade value. Some schools use different bonus amounts, so check your specific school's policy for the exact figures used on your transcript.
Can weighted GPA be higher than 4.0?
Yes. Because AP and Honors courses add a bonus on top of the standard 4.0 maximum, a student earning A grades in multiple AP or Honors classes can have a weighted GPA above 4.0, sometimes reaching 4.5 or higher depending on their course load.
Which GPA do colleges look at, weighted or unweighted?
Many colleges recalculate GPA using their own weighting formula rather than using either number directly from your transcript, since weighting policies vary widely between high schools. Some colleges consider only unweighted GPA to standardize comparisons across applicants from different schools.
Does every school weight GPA the same way?
No. Weighting policies vary significantly between schools and districts, some add +0.5 for Honors and +1.0 for AP, others use different bonus amounts, cap the maximum grade points, or do not weight GPA at all. Always check your own school's specific grading policy.
Should I use weighted or unweighted GPA on college applications?
Report both if your school provides both, since some colleges want unweighted GPA specifically while others compare weighted GPAs contextually alongside your school's profile. Your school counselor or transcript typically indicates which GPA is officially recorded.
How do I calculate my GPA if I only took regular courses?
If none of your courses are Honors or AP/IB, your weighted and unweighted GPA will be identical, since the weighting bonus for regular courses is zero. In that case, this calculator behaves the same as a standard unweighted GPA calculator.
Does credit hours affect weighted GPA the same way as unweighted GPA?
Yes. Both weighted and unweighted GPA are credit-weighted averages, a course worth more credit hours (like a year-long class worth 1.0 credit versus a semester class worth 0.5 credit) contributes proportionally more to both GPA calculations.
What is a good weighted GPA for college applications?
This varies widely by the target colleges' selectivity and your school's specific weighting scale, but a weighted GPA above 4.0 (indicating a mix of A grades in Honors or AP courses) is generally viewed favorably by selective colleges, alongside the rigor of the specific courses taken.
