GPA Calculator

Calculate GPA, cumulative grade point average for college

What is the GPA Calculator?

The gpa works like this: it converts letter or percentage grades into grade points using a 4.0 scale and weights them by credit hours to produce a semester or cumulative GPA. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.

How to use the GPA Calculator

1. Enter the values the calculator asks for.
2. Double-check the unit or period next to each field (per month vs per year, cm vs m).
3. Read the result together with the breakdown shown beneath it.
4. Adjust one input at a time to compare scenarios side by side.

Frequently asked questions

How do credit hours affect GPA?

A 4-credit course counts twice as much as a 2-credit one - that is why one bad grade in a heavy course hurts more.

Does this match my school's scale?

It uses the common US 4.0 scale. Some schools cap A+ at 4.0, others at 4.3 - adjust expectations accordingly.

How do credit hours change the result?

Each grade point is weighted by its course's credits, so an A in a 4-credit course counts twice as much as an A in a 2-credit course - one weak heavy course drags the GPA more than a light one.

Does it handle A+ or 4.3 scales?

The default mapping caps A+ at 4.0 on the common US scale; if your school caps at 4.3, read the result as slightly conservative and adjust the exceptional rows.
