About this tool
CGPA, made simple
CGPA — the Cumulative Grade Point Average — is how most Indian universities and many schools summarise academic performance in a single number, usually on a 10-point scale. This CGPA calculator and converter does three jobs: it computes your CGPA from your subject grades, converts a CGPA into the equivalent percentage, and converts a percentage back into a CGPA.
To calculate CGPA from scratch, add a row for each subject with its grade points and credit hours. CGPA is a credit-weighted average, so a high-credit subject counts more than a one-credit elective — the tool multiplies each subject's points by its credits, sums them, and divides by the total credits. It supports both the 10-point and 4-point scales and shows an equivalent percentage alongside the result.
Conversions are where students most often get stuck, because there is no universal CGPA-to-percentage formula. Each institution defines its own, so the converter lets you choose: CBSE's widely used CGPA × 9.5, VTU's CGPA × 10 − 7.5, Mumbai University's CGPA × 7.25 + 11, Anna University's (CGPA − 0.5) × 10, or a custom multiplier if your university publishes a different one. Pick the formula that matches your marksheet and the conversion is exact.
Whether you're filling in a job or higher-studies application that asks for a percentage, projecting the CGPA you need this semester, or just checking where you stand, the calculator saves you the error-prone arithmetic. Everything runs privately in your browser, so your grades never leave your device. For the US 4.0 letter-grade system, use the GPA calculator linked below.

FAQ
Frequently asked questions
How is CGPA calculated from grades?
CGPA (Cumulative Grade Point Average) is the credit-weighted average of your grade points: multiply each subject's grade points by its credits, add those up, and divide by the total credits. Add a row for each subject in the calculator, enter its grade points and credits, choose a 10- or 4-point scale, and it computes your CGPA and an equivalent percentage instantly.
How do I convert CGPA to percentage?
There's no single universal formula — each university defines its own. The converter lets you pick yours: CBSE/generic (CGPA × 9.5), VTU (CGPA × 10 − 7.5), Mumbai University (CGPA × 7.25 + 11), Anna University ((CGPA − 0.5) × 10), or a custom multiplier. Enter your CGPA and it returns the percentage; the reverse mode converts percentage back to CGPA.
Which CGPA-to-percentage formula should I use?
Use the one your own university or board specifies, as it's what appears on your official documents. CBSE's × 9.5 is the most common in Indian schools, while engineering universities like VTU and Anna use their own. If you're unsure, check your institution's grading rules or marksheet, or use the custom multiplier if they publish one.
What's the difference between a 10-point and 4-point scale?
Indian universities typically grade on a 10-point CGPA scale, while US institutions use a 4.0 GPA scale. This tool defaults to 10-point but lets you switch to 4-point; for the US 4.0 system with letter grades, use our dedicated GPA calculator instead.
Is my data private?
Yes. All calculations run in your browser and your grades are never uploaded or stored anywhere.
