VTU: CGPA to percentage

Visvesvaraya Technological University (VTU) in Karnataka is one of the most-searched universities for CGPA conversion, partly because its formula is not a plain ×10 — it uses an offset, which trips up students who apply a generic rule.

The VTU pattern

VTU's official conversion subtracts a fixed amount from the CGPA before scaling — the widely cited form is (CGPA − 0.75) × 10. That offset means a VTU 8.0 CGPA does not become 80%; it becomes 72.5%. Students who assume ×10 consistently overstate their percentage, which can cause problems on eligibility forms.

Why the offset exists

The subtraction aligns VTU's grade-point bands with the underlying marks more accurately than a flat multiply would. It is a deliberate part of the university's regulation, not an error — which is exactly why using VTU's own formula matters.

Convert it right

Open the VTU page on the CGPA to percentage calculator; it applies VTU's source-verified formula (including the offset) and cites the regulation. Enter your CGPA and you get the percentage VTU's rule actually produces.

As always, confirm against your VTU grade card — and note your specific scheme/regulation, since details can change between regulation cycles. For the reverse direction, the percentage to CGPA page inverts the same offset formula.

The offset, shown across the scale

VTU's −0.75 offset shifts every result down by 7.5 points versus a plain ×10: a 7.0 CGPA is 62.5% (not 70%), an 8.0 is 72.5% (not 80%), a 9.0 is 82.5% (not 90%). The gap is constant, which makes the error from forgetting the offset both large and predictable — always in the direction of overstating your percentage.

Key takeaways

• VTU uses (CGPA − 0.75) × 10, not a plain ×10.
• The offset lowers every result by 7.5 points versus ×10.
• A VTU 8.0 CGPA is 72.5%, not 80%.
• Use the VTU page, which applies the offset and cites the regulation.
