High School GPA Calculator: Weighted and Unweighted
Our high school GPA calculator helps students, parents, and counselors accurately compute both weighted and unweighted GPAs — the two most commonly reported GPA types on high school transcripts. Whether you are a domestic student in the US, an international student in Canada or Australia following a similar curriculum, or a student in the UK preparing to convert your grades for US college applications, this tool gives you an immediate and accurate picture of your academic standing.
High school GPA is one of the most critical factors in college admissions decisions. US colleges typically review both your weighted and unweighted GPA, and many use the unweighted 4.0 scale for comparing applicants across different schools. Understanding both numbers — and how they differ — gives you a significant advantage when evaluating where you stand and what you need to improve.
Weighted vs. Unweighted GPA: What's the Difference?
An unweighted GPA treats all courses equally on a 4.0 scale. An A in a regular English class and an A in AP Physics both count as 4.0. This makes your GPA easy to compare across schools but doesn't account for course difficulty.
A weighted GPA gives extra points for harder courses. Honors classes are typically graded on a 4.5 scale, while AP (Advanced Placement), IB (International Baccalaureate), and dual-enrollment college courses are graded on a 5.0 scale. This means a student who takes challenging coursework can earn above a 4.0 weighted GPA — sometimes as high as 5.0 or beyond at some schools.
How AP and IB Courses Affect Your High School GPA
AP and IB courses are highly valued by colleges because they demonstrate readiness for university-level work. Earning a B (3.0) in an AP course translates to a 4.0 on the weighted scale — the same as earning an A in a regular class. This incentivizes students to challenge themselves. International students who completed IB Diploma Programme courses abroad can use this calculator to convert their IB grades (1–7 scale) to the US GPA system for college applications.
High School GPA for International Students
Students from the UK, Australia, and Canada who are applying to US universities often need to convert their grades to the 4.0 GPA scale. UK students with A-Levels and GCSE results, Australian students with ATAR scores and VCE grades, and Canadian students with provincial transcripts can all use this calculator's conversion tables to understand how their academic record compares on the US scale.
What GPA Do You Need for Top Colleges?
- Ivy League & elite universities: Typically 3.9–4.0 unweighted (4.5+ weighted)
- Top-50 national universities: Typically 3.5–3.9 unweighted
- State universities / good schools: Typically 3.0–3.5
- Community college / open enrollment: No minimum GPA requirement
Remember that GPA is just one factor. Colleges also weigh standardized test scores, extracurricular activities, essays, and letters of recommendation.
