High School GPA Calculator — Free GPA Calculator

This high school GPA calculator and college CGPA calculator updates your grade point average instantly as you add courses — no Calculate button needed. How to use the GPA calculator: 1. Choose your grade format: letter grades (A+, A, A−, B+…) or percentage grades (0–100 scale). 2. Add courses to each semester. Enter the course name, grade, and credits (most year-long high school courses = 1 credit; semester courses = 0.5 credit). 3. Toggle Weighted on to apply the US weighted GPA scale: Honors/Pre-AP = +0.5 per grade point, AP/IB = +1.0. 4. Your cumulative GPA appears at the top and each semester GPA shows in its card header. GPA calculator without credits: Set every course to 1 credit for an equal-weight average — standard for most middle school GPA calculators. College / University GPA: Switch to the College tab. Enter previous CGPA and credit hours if you have prior semesters already recorded, then add new semester courses. The cumulative GPA calculator merges both automatically.

**How the high school GPA calculator works** The GPA formula is: GPA = Sum(grade points × credits) ÷ total credits. This weighted average means a 4-credit AP course affects your GPA four times more than a 1-credit elective. Every American high school and college GPA calculator uses this same core formula. **Unweighted GPA scale (4.0)** A/A+ = 4.0 · A− = 3.7 · B+ = 3.3 · B = 3.0 · B− = 2.7 · C+ = 2.3 · C = 2.0 · D = 1.0 · F = 0.0. This is the standard scale used by the College Board and accepted by every US university. **Weighted GPA calculator scale (5.0)** AP and IB courses add +1.0 to the base grade point (A = 5.0). Honors and Pre-AP courses add +0.5 (A = 4.5). Regular courses receive no boost. This scale rewards students who take rigorous coursework. Many online GPA calculators incorrectly add +1.0 to Honors — this calculator uses the correct +0.5. **Middle school GPA calculator** Middle school GPA works identically to high school GPA mathematically. Most middle schools use the unweighted 4.0 scale without credits (every course counts equally). Set all credits to 1 in this calculator to replicate that approach. **Cumulative GPA vs. semester GPA** Your semester GPA covers only that term. Your cumulative GPA covers every semester since 9th grade, weighted by credits. College applications, NCAA eligibility, and scholarship applications all require your cumulative GPA — not just your most recent semester. **GPA calculator with AP courses** When using the weighted GPA calculator, mark AP and IB courses as "AP" and Honors courses as "HON." The calculator applies College Board-standard weights: AP/IB = +1.0, Honors = +0.5. A student taking five AP courses and earning mostly B+'s will often have a weighted GPA of 4.0–4.3 despite an unweighted GPA around 3.3. **What your GPA unlocks** 3.9–4.0 unweighted: Top 10% nationally; competitive for highly selective colleges. 3.7+: Strong for selective universities; qualifies for most merit scholarships. 3.0+: Good standing; qualifies for most state university programs. 2.3+: NCAA Division I eligibility minimum for core courses. 2.0+: Minimum threshold for most college admissions. **How much will my GPA go up?** This depends entirely on how many credits you have already completed. With 60 credits at a 2.8 GPA, earning 4.0 in 20 new credits raises you to 3.07. With 90 credits at 2.8, the same 20 perfect credits only reach 2.91. The earlier you build strong grades, the more impact they have.
