High School GPA Calculator
Calculate weighted and unweighted GPA with AP/Honors bonuses. Three precision levels โ from quick calculation to full 4-year transcript analysis.
How to Use This High School GPA Calculator
Enter each course with its grade, credits, and course type (Regular, Honors, or AP/IB). The Unweighted tab gives you your standard 4.0 GPA, the Weighted tab adds AP/Honors bonuses, and College-Ready maps your GPA to admissions tiers. All results update instantly as you type.
The Advanced tier below lets you track GPA year-by-year with a side-by-side weighted vs. unweighted trend chart and scenario presets for common high school paths. For a complete 4-year transcript analysis with subject-area breakdowns and college readiness scoring, see the Professional tier.
Weighted vs. Unweighted GPA Formula
Weighted GPA = ฮฃ(Weighted Grade Points ร Credits) รท Total Credits
Weighted Grade Points: Regular = base | Honors = base + 0.5 (max 4.5) | AP/IB = base + 1.0 (max 5.0)
An unweighted GPA treats every course equally โ an A in Regular English and an A in AP English both contribute 4.0 points. A weighted GPA rewards course difficulty by adding bonus points for Honors and AP/IB courses, typically running on a 5.0 scale.
Grade Point Values โ Weighted Scale
Regular courses: A/A+ = 4.0 | A- = 3.7 | B+ = 3.3 | B = 3.0 | B- = 2.7 | C+ = 2.3 | C = 2.0
Honors courses (+0.5): A = 4.5 | A- = 4.2 | B+ = 3.8 | B = 3.5 | B- = 3.2
AP / IB courses (+1.0): A = 5.0 | A- = 4.7 | B+ = 4.3 | B = 4.0 | B- = 3.7
Step-by-Step Example
Junior year with 4 AP courses:
AP English Lit (A-, 1 credit) โ Weighted: 4.7 | Unweighted: 3.7
AP Calculus AB (B+, 1 credit) โ Weighted: 4.3 | Unweighted: 3.3
Honors Chemistry (B+, 1 credit) โ Weighted: 3.8 | Unweighted: 3.3
Regular History (A, 1 credit) โ Weighted: 4.0 | Unweighted: 4.0
Weighted GPA: (4.7 + 4.3 + 3.8 + 4.0) รท 4 = 4.20
Unweighted GPA: (3.7 + 3.3 + 3.3 + 4.0) รท 4 = 3.58
| Course | Year | Subject | Type | Grade | Credits | |

Do Colleges Prefer Weighted or Unweighted GPA?
Most colleges consider both GPAs and often recalculate your GPA on their own scale. What matters more is the combination of your GPA and course rigor โ taking AP and Honors courses and earning B grades typically looks better than taking only easy courses with straight A's.
