Free Online GPA Calculators — College, High School & University GPA
GPA calculators are the essential academic tools for students at every level — from middle school through law school. Whether you need to track your semester GPA, compute your cumulative grade point average across multiple terms, or calculate the specialised grading scale used by a specific university like UC Berkeley, ASU, Purdue, Rutgers, Penn State, Mizzou, or UW, our free online GPA calculators handle all of it instantly.
Each calculator on CalcDash uses the exact grading scale and rules for its context. University-specific calculators use the official grading scales published by those institutions — including schools that don't award A+, use non-standard point values like Rutgers (B+ = 3.5), or apply quarter-unit systems like the University of Washington. The LSAC GPA Calculator uses the Law School Admission Council's official conversion grid and includes all undergraduate attempts, not just recent ones.
These tools are trusted by college students managing academic standing, high schoolers calculating weighted and unweighted GPAs for college applications, international students converting grades, pre-law students estimating their LSAC GPA before law school applications, and middle school students learning to track their academic progress. All calculators are free, mobile-friendly, and require no signup.

- How is GPA calculated?
- GPA (Grade Point Average) is calculated by multiplying each course's grade points by its credit hours, summing those "quality points" across all courses, then dividing by the total credit hours. For example: an A (4.0) in a 3-credit course = 12 quality points. If you have 30 total credit hours with 114 total quality points, your GPA is 3.80.
- What is the difference between weighted and unweighted GPA?
- Unweighted GPA uses the standard 4.0 scale for all courses regardless of difficulty. Weighted GPA adds bonus points for advanced courses — typically +0.5 for Honors and +1.0 for AP/IB — giving a maximum of 5.0. Most colleges use unweighted GPA for admissions comparison, but weighted GPA reflects the challenge of your course load.
- What GPA do I need for the Dean's List?
- Dean's List requirements vary by institution, but 3.5 is the most common threshold for full-time students. Some schools require 3.75 or higher. Always check your specific university's published requirements, as enrollment status (full-time vs part-time) often affects eligibility.
- How does LSAC calculate GPA differently from my university?
- LSAC recalculates GPA from every undergraduate institution you attended, including all repeated courses (both the original grade and the repeat are counted), courses taken after graduation, and grades from transfer institutions. LSAC also uses its own grade conversion grid with A+ = 4.33 — different from most universities' scales. Your LSAC GPA will often differ from your official university GPA.
- Are these GPA calculators accurate for my school?
- University-specific calculators (Berkeley, ASU, Purdue, Rutgers, PSU, Mizzou, UW) use the grading scales published by each institution and are updated to reflect current policies. For academic decisions, always cross-check with your registrar or student portal, as universities occasionally update their grading policies.
