High School GPA Calculator
High school GPA calculator, weighted or unweighted. Add Honors (+0.5) and AP/IB (+1.0) bonus points for a weighted GPA above 4.0, or keep the standard 4.0 scale. Free.

A high-school GPA can be unweighted (every course on the 4.0 scale) or weighted (a bonus for harder courses, commonly +0.5 Honors and +1.0 AP/IB), which lets a weighted GPA exceed 4.0. Both are credit-weighted when courses carry different credits.
Worked example
AP A = 4.0 + 1.0 = 5.0; Honors B = 3.0 + 0.5 = 3.5; regular A = 4.0. Averaged: 4.17 weighted, or 3.67 if none were weighted.
How to use the high school gpa calculator
Turn on “Weighted” for Honors/AP
A course-type column appears; set each class to Regular, Honors or AP/IB.
Or leave it off for unweighted
An unweighted high-school GPA caps every class at 4.0 — the number many colleges recalculate to.
Enter credits and grades
If your school gives every class equal weight, use 1 credit each; otherwise use its credit values.
Compare both numbers
Know your weighted and unweighted GPA — schools and colleges ask for different ones.
Weighted vs unweighted in high school
Unweighted caps at 4.0; weighted adds bonus points for rigor and can reach 5.0 with straight AP A’s. Class rank is often built on weighted GPA, while colleges frequently recalculate to unweighted for fair comparison.
4.0, 5.0 and other scales
The most common weighting is +1.0 for AP/IB and +0.5 for Honors on a 4.0 base (so a weighted scale tops out near 5.0). Some districts use different bonuses or a 6.0 scale — set the course types to match yours.
Which GPA do colleges want?
Report the GPA on your transcript, and know both. Many admissions offices recalculate using their own scale and course list, so your “official” number may differ from any single calculator.
