Thirteen calculators, one job each, nothing saved to a server.
GPACalcTools started from a plain annoyance: most GPA calculators show a number without ever saying which grading convention produced it. This one says so, on every single page, and links to where you can check that convention against your own school.
Thirteen tools, grouped by what they solve rather than bolted together at random. Five compute a GPA in some form, semester, cumulative, weighted, plain, college or high school flavored. Three answer the "what score do I need" question for a course, a final, or an exam. The rest, fraction, algebra, test-score and IQ percentile, cover the everyday math and score conversions students kept asking for alongside GPA.
State the convention being used, run the arithmetic exactly as stated, and link to where a reader can verify that default against their own school's policy. That is the entire design brief. No calculator here quietly assumes you already know which scale it is applying.
Chris Terry owns and operates GPACalcTools, along with the rest of the Encore Editorial network, through Encore Promotional Products. There is no guidance-counselor team behind the byline, and this page will not pretend otherwise: the authors page names exactly who writes the guides and what gets checked before anything publishes.
Every calculator computes inside your browser and nowhere else. There is no account to create, no history saved between visits, nothing that leaves your device. The mechanics are laid out in full on the privacy page.
An output here is a planning number built from a stated convention plus your inputs, not a transcript entry and not a substitute for your school's own grading policy. When the default does not match what your registrar actually does, and it sometimes will not, the GPA scale page explains why and how to adjust.
Advertising and a short list of affiliate partnerships cover the cost of hosting thirteen tools and the time spent maintaining them; clicking through one and buying something may earn us a commission at no cost to you. That revenue has no influence over what any formula returns. Full disclosure sits at the bottom of every page.
