About FinalGradr
Last updated: August 4, 2026
Free, private grade and GPA calculators that just work — no account, no app, no uploads.
What FinalGradr is
FinalGradr is a small collection of single-purpose calculators that answer the questions students and teachers ask most around exam season: "What do I need on my final?", "What's my GPA?", "What's my overall grade so far?" Each tool is on its own page with the formula, a worked example and a short FAQ, so you can both get the answer and understand it.
What makes it different
- Private by design. Every calculation runs in your browser with JavaScript. The numbers you type never leave your device and are never uploaded to a server. See our privacy policy.
- Free, no sign-up. There is nothing to install and no account to create. The tools are funded by unobtrusive advertising.
- Fast and offline-friendly. Pages are plain HTML and load instantly, even on a phone with a weak connection in an exam hall.
- Clear about the maths. We show the formula behind each result so you can trust it and reproduce it by hand.
The calculators
How we check the maths
Every formula on this site is published on the page that uses it — nothing is a black box. Before a calculator ships, the FinalGradr Editorial Team verifies it three ways. First, each formula is cross-checked against the grading conventions published by universities and school districts in their syllabi, registrar pages and student handbooks, so the defaults reflect how courses are actually graded rather than how we assume they are. Second, every worked example shown on a page is recomputed by hand, independently of the code, and the two results must match to the digit. Third, we test edge cases deliberately: zero weights, targets above 100%, empty credit hours and failing grades all have defined, clearly-flagged behaviour instead of silent nonsense. When a reader reports a discrepancy through the contact page, we re-derive the calculation, correct the page if needed, and update the "Last updated" date you see under each title.
What our numbers cover — and what they don't
FinalGradr's defaults cover the systems most students actually encounter: the US 4.0 letter scale (with plus/minus steps), the 4.3/4.33 variant, the 5.0 weighted high-school scale with honors (+0.5) and AP/IB (+1.0) bonuses, percentage-based marking, and the Indian 10-point SGPA/CGPA system including the common ×9.5 percentage convention. Our international conversion pages summarise widely used equivalences for ten countries, including the UK's degree classifications, Canada's per-university scales, and systems used in India, Australia, Germany, France, Japan, China and the Netherlands. Two honest limits: conversion tables are orientation aids, not official credential evaluations — for admissions or employment paperwork, the receiving institution's own published equivalence always wins; and because letter-grade cutoffs, rounding rules and repeat policies are set locally, your syllabus and registrar override any default we ship. Our guides section explains each system in depth so you can check every step yourself.
A note on accuracy
Grading policies differ between schools, departments and even individual instructors — letter-grade cutoffs, rounding rules and how the final is weighted all vary. FinalGradr uses the most common conventions, but the results are for guidance only. Always check your syllabus and confirm with your instructor before relying on a number.
