Our mission: To make academic calculation simple, accurate, and universally accessible — so every student, regardless of where they study or what system they follow, can understand their academic standing with clarity and confidence.
🌍 Why Delvox.xyz Exists
Honestly, it started with frustration. Search for a GPA calculator and you land on something built for one grading system only. Search for a percentage-to-grade converter and half the results are broken, ad-stuffed pages that do not even load properly on a phone. Students trying to calculate their CGPA, or convert their marks to a GPA for a foreign application, had nowhere reliable to go.
Grading systems are genuinely complicated across borders. The 4.0 GPA scale, degree classifications, percentage-based grading, CGPA systems — they all work differently, and many of them vary further from one university to the next. No single tool was covering all of this in one place. Students were the ones paying the price, wasting time piecing together answers from multiple unreliable sources instead of focusing on their actual studies.
We built Delvox.xyz to be that one reliable destination. Not for one grading system, not for one type of institution — for every student, wherever they study.
🔢 What We Offer
Delvox.xyz is home to a growing library of free academic calculators, each built with care and tested against real academic systems used around the world. Our tools include:
- Grade Calculators — Work out your final grade based on assignments, exams, and weightings
- GPA Calculators — Calculate your GPA using US 4.0, percentage-based, or custom scales
- CGPA Calculators — Track your cumulative academic performance across semesters

Every tool is free, works directly in your browser, and requires no account, no sign-up, and no download.
Privacy first: We never store your calculation inputs. Every result is processed entirely within your browser — your academic data stays with you.
⭐ What We Actually Care About
Accuracy is non-negotiable for us. A calculator that gives a wrong result is worse than no calculator at all — it gives a student false confidence going into an exam or a grade appeal. Every formula on Delvox.xyz is researched against real academic systems and checked before it goes live. When someone reports an error, we treat it seriously and fix it fast.
We also made a decision early on that this platform would never sit behind a paywall or a subscription. Students already have enough financial pressure. The tools stay free — that is not going to change.
And simplicity matters more than we initially expected. Early versions of some tools had too many options, too many fields. Students do not want a tutorial — they want to enter their marks and get an answer. We stripped things back and the tools became genuinely more useful for it.
🎓 Built for Every Kind of Student
Whether you are a high school student tracking your end-of-year grades, an undergraduate managing your GPA across multiple subjects, or a postgraduate student calculating your CGPA before graduation — Delvox.xyz has a tool for you.
We also support teachers and academic advisors who need quick, reliable reference calculations when working with students. Our tools are simple enough for anyone to use, and precise enough to trust.
You do not need to know which formula your institution uses. Our calculators are built to cover the most widely used academic systems in the world, and we are constantly expanding our library to cover more.
🚀 Our Commitment to Students
Delvox.xyz is not a finished product — it is a growing platform. Every tool we add, every formula we refine, and every improvement we make is driven by one purpose: helping students succeed academically with better information and clearer understanding of where they stand.
We believe that when students have accurate tools at their fingertips, they make better decisions — about which subjects to prioritise, which grades to aim for, and how close they are to the goals they have set for themselves. That clarity is what motivates us to keep building.
If you have a suggestion for a calculator we should add, a formula that needs correcting, or simply want to share how Delvox.xyz has helped you — we genuinely want to hear from you.
