GPACalc is a free GPA calculator for high school and college students: course rows in (name, credits, letter grade, level), weighted or unweighted GPA out — per semester, cumulative across semesters, and a target mode that solves for the average you need.

Why this site exists

Every student hits the same wall at registration or report-card time: “what does this grade do to my GPA?” The math is one line — Σ(points × credits) ÷ Σcredits — but doing it across twelve courses, three semesters, two weighting schemes and a pass/fail elective by hand is exactly the kind of arithmetic people get wrong. This tool makes the whole thing live: change a grade, watch the GPA move. Flip the weighting toggle, watch the same transcript produce its two honest numbers.

Where the numbers come from

The point values are the standard published conventions, not invented scales: A/A+ = 4.0 with the usual +/− ladder (A− 3.7, B+ 3.3 … D− 0.7, F 0), an uncapped variant where A+ = 4.3, and a flat-letter scale for schools without +/−. Weighting follows the most common district convention — honors +0.5, AP/IB +1.0, applied to passing grades only. Pass/fail and withdrawal marks are excluded from GPA exactly as registrars exclude them: no quality points, no denominator credits. Every rule the calculator applies is stated on the page next to the controls.

One honest caveat: grading policy is local. Your school’s profile defines its own thresholds, bumps and caps — when the two disagree, the school’s version is the one on your transcript.

How the site works

Everything runs in your browser with plain JavaScript — all arithmetic in integer tenths, so a displayed 4.25 is exactly 4.25, not 4.2499. There’s no account, no upload, and nothing you type ever leaves your device. The page works offline once loaded.

Who maintains it

GPACalc is maintained by a small independent team building focused utility sites. The bar we hold: numbers a student could defend to a registrar.
