Why we built this
Most GPA calculators online force a single weighting policy (usually +0.5 / +1.0) and don't explain why your school's number is different. Some pop ads over the calculator before you can use it. Some require an account.
We took the opposite approach: every common weighting scale, transparent math, no signup, your data saves to your browser (never our servers), and the tools work properly on a phone.
How we're funded
The site is free. We may show display ads through standard networks, and we may include affiliate links to study tools we actually use (textbooks, prep courses, productivity apps). We don't sell your data — we don't collect it in the first place. No accounts, no tracking beyond standard analytics.
Editorial team and methodology
Our content is written and reviewed by an editorial team with backgrounds in K-12 education policy, college admissions, and quantitative tutoring. Every calculator page goes through three checks: (1) the underlying formula is unit-tested against published worked examples (College Board AP, NCES Digest, PrepScholar, College Transitions); (2) the article matches policies from primary sources like College Board, the U.S. Department of Education, and NACAC; (3) the page is reviewed for clarity, citations, and link integrity before publishing.
Articles carry a "last updated" date and a reviewer byline so readers can see when guidance was last verified. We re-check each page at least annually and after any material change in College Board, NCES, or federal financial-aid policy. See our full process at How to Calculate GPA, the methodology cornerstone for the site.
Accuracy and limits
Our calculations follow standard US grading systems. We unit-test the math against published examples (PrepScholar, College Transitions). That said, your school's policy is final — check the student handbook for the exact formula your transcript uses, and use the school weighting scale dropdown to match.
We cite our sources directly on the calculator pages. Common authoritative references include College Board, NCES (National Center for Education Statistics), U.S. Department of Education, NACAC, and World Education Services (WES) for international transcript conversion.
