GPA Calculators & Converters
Two different jobs live here. The calculators work out a GPA from your courses and credits — use cumulative to fold a prior transcript into this term, high school for weighted and unweighted side by side with AP and IB bonuses, and CGPA for 10-point and 5-point systems.
The converters translate a GPA you already have onto a different scale. Worth knowing before you use one: there is no single official conversion formula, and the common GPA ÷ 4 × 100 shortcut understates every US grade below an A. Both converters show which method they used and why. Need a single course grade instead? Grade calculators is the other hub.

Picking the right GPA tool
Start with the scale your transcript actually uses. A US transcript runs on the 4.0 scale, where an A is 4.0 and a C is 2.0. Indian and many other international marksheets run on a 10-point scale, and several Nigerian universities use a 5-point one. The CGPA calculator handles the non-US scales, including the Division and Class bands those systems report alongside the number.
Then decide how much of your record you are averaging. One term is a semester or term GPA. Every course you have ever taken, with a prior transcript folded in, is a cumulative GPA. High school students usually need two numbers at once — weighted, which adds a bonus for honors, AP, IB and dual-enrollment courses, and unweighted, which caps everything at 4.0 — and the high school calculator shows both side by side.
One warning about converting. There is no single official formula for turning a GPA into a percentage or moving between scales, and the popular shortcut of dividing by 4 and multiplying by 100 is simply wrong on the US scale — it reads a 2.0 as 50%, when a 2.0 is a C, around 73%. Both converters here show which method produced the number and what its limits are, so you can give an admissions office an answer you are able to defend. Where a form will accept your original scale, submitting that with the maximum stated is always safer than submitting a conversion.
