CGPACalculation.store is a free, fast, and accurate online platform built specifically for Indian students who need to convert CGPA to percentage, SGPA to CGPA, or estimate GPA on the 4.0 scale for placements, higher studies, government job applications, and study-abroad submissions. We support every major Indian university grading system — CBSE, VTU, Anna University, Mumbai University, SPPU, GTU, KTU, and more — with the exact formulas each institution officially uses. This page explains our story, mission, methodology, accuracy commitment, and how we plan to keep serving Indian students through 2026 and beyond.
CGPACalculation.store offers a full suite of academic calculators built for Indian students. Each tool is mobile-friendly, ad-light, requires zero signup, and gives instant results with formula transparency.
We use the official formula published by each university or the regulatory body. We do not invent shortcuts. Here is the exact methodology behind our conversions:
Every formula above is sourced from public university circulars, examination handbooks, and references aligned with UGC and AICTE guidelines. When a university updates its policy, we update our calculator within the same academic cycle.
CGPACalculation.store is an independent education-tools project built by a small team of engineers, educators, and product designers based in India who have all personally navigated the maze of converting CGPA to percentage for university forms, placement portals, and study-abroad applications. We collectively hold degrees from Indian engineering universities and have direct experience with the inconsistencies between university grading rules and what online calculators showed us.
We are not a corporate education company. We do not sell coaching, courses, admission services, or scholarships. We are not affiliated with any university, board, or recruiter. We do not have a partnership with CBSE, VTU, Anna University, Mumbai University, or any other institution. We build the calculator. We document the formula. We let you do the conversion. That is the entire product.
This independence matters because it means our calculator results are not optimized to look favourable, sell anything, or push students toward a particular service. We show the numbers exactly as the official formula produces them.
Our mission is simple: every Indian student should have free, accurate, instant access to the exact CGPA-to-percentage conversion their university officially uses, on any device, without signup, without ads-blocking-content, and without confusion about which formula applies.
In 2026, the Indian higher education ecosystem still has a fragmented grading conversion landscape. The same 8.0 CGPA becomes 76% under CBSE rules, 80% under VTU, 72.5% under Anna University, and 67.8% under Mumbai University. Students filling job applications or study-abroad portals routinely encounter conflicting numbers across different online calculators, leading to confusion at best and document verification problems at worst.
We exist to fix that. Our 2026 commitment is to maintain, expand, and continuously verify our calculator coverage so that no Indian student has to guess which percentage is correct for their institution.
Most Indian students convert CGPA to percentage at three critical moments in their academic journey:
At each of these moments, the form may explicitly demand a percentage. Some forms specify the conversion method (CBSE ×9.5, for example). Many do not. Students then turn to Google, find five different calculator websites, and get five different answers — sometimes off by 5–10 percentage points. This creates real harm: wrong figures get submitted, profiles get filtered out incorrectly, and verification mismatches surface later during background checks.
CGPACalculation.store solves this by offering all common formulas in one place, with clear labels showing which formula belongs to which university. Students can compare the outputs side by side and use the one their institution officially mandates. We are the cross-verification layer between confusing calculator websites and official university policies.

| BPUT Odisha | Odisha | CGPA × 10 |
| Calicut University | Kerala | (CGPA − 0.5) × 10 |
We also cover central universities like Delhi University, JNU, BHU, and IGNOU under their respective grading guidelines. Most central universities follow the standard ×9.5 CBSE method, though some specific programs may publish their own conversion rule. For autonomous institutions like IITs, NITs, IIITs, BITS Pilani, and IISc, we recommend students refer to their institute's official grade card directly, as these institutions often use percentage-equivalent grading internally and may not require explicit CGPA-to-percentage conversion for graduation.
Accuracy is the entire point of this product. A calculator that gives the wrong percentage causes more harm than no calculator at all. Here is exactly how we verify each formula before adding it to our platform:
Our accuracy commitment does not mean our calculator can replace your university's official transcript. The official transcript remains the legal source of truth. Our role is to help you understand what your CGPA likely converts to under the standard formula and to flag when different formulas produce different results — so you can choose the right one for your specific form.

Although we work hard on accuracy, please treat our calculator outputs as a planning and reference tool rather than as a substitute for your official university transcript. Here are the key limitations to understand:
For high-stakes submissions — visa applications, foreign university admissions, government job documentation — always use the percentage stated on your official mark sheet, degree certificate, or transcript issued by your university, not a calculator output.
We genuinely read every email and message students send us. Whether it is a formula correction, a request for a new university, a bug report, or a feature suggestion, we treat it seriously.
You can reach us in the following ways:
Response time is typically within 48 hours for general queries and within 7 days for formula correction requests (we need time to verify the official source). We may follow up with questions if we need clarification or evidence for a formula change.
