This free percentage to CGPA calculator converts your marks to CGPA on the 10-point scale in seconds — but unlike most percentage to CGPA converter tools online, it doesn’t force every student through the same 9.5 divisor. Convert percentage to CGPA for Anna University, VTU, GTU, Mumbai University, or the general CBSE 10-point scale, each using that institution’s own official formula, so the number you get actually matches your transcript.
Most calculators quietly assume you’re on the CBSE scale. If your marksheet says Anna University, VTU, or GTU, that assumption is wrong — see exactly why in the formula guide below, or jump straight to the calculator and pick your institution from the dropdown. Already have a CGPA and need the reverse conversion? Use the CGPA to Percentage Calculator instead.

Percentage to CGPA Calculator — Pick Your University’s Formula
Select the formula that matches your institution, enter your percentage, and get your CGPA on the 10-point scale instantly. Not sure which one applies to you? The formula guide below walks through it in under a minute. If you already have semester-wise SGPA scores instead of a single percentage, use the SGPA to CGPA Conversion Calculator to roll them up first.
The 4.0-scale figure is a general linear approximation ((percentage ÷ 100) × 4), used for reference on international applications — it is not an official conversion. For formal use abroad, a WES or equivalent credential evaluation is usually required.
How to Use the Percentage to CGPA Calculator
Converting your percentage to CGPA correctly takes five steps — skipping the first one is exactly what produces a CGPA that doesn’t match your transcript.
- Find your grading regulation. Check the top of your marksheet, your university’s academic regulation PDF, or the grading policy page on your institution’s website. This tells you which formula is officially yours.
- Select the matching option from the dropdown. Choose CBSE/General, Anna University, the correct VTU scheme year, GTU, or Mumbai University. If your institution isn’t listed, use Custom and enter its published divisor and offset.
- Type your percentage into the input field. Use the exact aggregate percentage shown on your marksheet, as a number between 0 and 100 — decimals like 78.5 are fine.
- Click “Calculate CGPA.” The result box updates instantly with your CGPA on the 10-point scale, plus an approximate 4.0-scale GPA underneath it.
- Verify against your official transcript formula before using it on any form. Scheme years change — VTU’s 2021 update is a good example — so a formula that was correct for an older batch may not apply to you.

Which Percentage to CGPA Formula Applies to You?
This is the question almost every other calculator skips. Here’s how to place yourself in under a minute.
Use the 9.5 divisor
Standard for CBSE-affiliated schools and many general Indian university programs that don’t publish their own conversion circular.
CGPA = Percentage ÷ 9.5Use the 10 divisor — not 9.5
Confirmed by Anna University’s own Letter No. 001/ACOE(UDs)/2021, applying across the R2013, R2017, and R2021 regulations.
CGPA = Percentage ÷ 10Use the 10 divisor, no offset
The current VTU scheme dropped the 0.75 offset used in earlier years. Check your admission year, not just “VTU,” before picking this one.
CGPA = Percentage ÷ 10Add 0.75 after dividing
Older VTU schemes calibrate grade boundaries higher, so the reverse conversion needs the 0.75 addition to land back on the correct CGPA.
CGPA = (Percentage ÷ 10) + 0.75Add 0.5 after dividing
Follows the AICTE guideline for CBCS scales calibrated above the standard UGC bands — the same principle behind VTU’s older offset, at a smaller value.
CGPA = (Percentage ÷ 10) + 0.5Use the legacy linear formula
Preserves continuity with Mumbai’s older 7-point scale, so it doesn’t reduce to a clean divide-only formula like the others.
CGPA = (Percentage − 11) ÷ 7.1Same Percentage, Different CGPA: A Direct Comparison
Here’s what makes the single-divisor approach risky — these are the actual CGPA values six formulas produce from identical percentages.
| Percentage | CBSE (÷9.5) | Anna Univ. (÷10) | VTU New (÷10) | VTU Old (+0.75) | GTU (+0.5) | Mumbai Univ. |
|---|---|---|---|---|---|---|
| 60% | 6.32 | 6.00 | 6.00 | 6.75 | 6.50 | 6.90 |
| 65% | 6.84 | 6.50 | 6.50 | 7.25 | 7.00 | 7.61 |
| 70% | 7.37 | 7.00 | 7.00 | 7.75 | 7.50 | 8.31 |
| 75% | 7.89 | 7.50 | 7.50 | 8.25 | 8.00 | 9.01 |
| 80% | 8.42 | 8.00 | 8.00 | 8.75 | 8.50 | 9.72 |
| 85% | 8.95 | 8.50 | 8.50 | 9.25 | 9.00 | 10.00* |
| 90% | 9.47 | 9.00 | 9.00 | 9.75 | 9.50 | 10.00* |
*Mumbai University’s linear formula exceeds 10.0 at high percentages; reported CGPA is capped at the 10.0 scale maximum. At 75%, the gap between formulas already spans a full 1.5 CGPA points (7.50 to 9.01) — enough to change which distinction band a student falls into. See what a given CGPA typically represents on the GPA Scale guide.
Percentage to CGPA Conversion Examples
Three complete worked examples, one per formula family, showing the full calculation.
CGPA = 82 ÷ 9.5 = 8.63
CGPA = (68 ÷ 10) + 0.75 = 6.8 + 0.75 = 7.55
CGPA = (74 ÷ 10) + 0.5 = 7.4 + 0.5 = 7.90
Notice the VTU and GTU examples both start by dividing the percentage by 10, exactly like Anna University — the only difference is the offset added afterward, and that offset is what a formula that ignores scheme year gets wrong.
