Work out your GPA
One row per course. Leave the grade blank for any course you don’t want counted.
Your GPA

Pick a grade for at least one course and your unweighted and weighted GPA appear here.
How it works
How a GPA is calculated
- 1
Turn each grade into points
Every letter grade has a value on the 4.0 scale: A is 4.0, B is 3.0, C is 2.0, and the plus and minus grades sit in between.
- 2
Weight by credits
Multiply each course’s points by its credits, add them up and divide by the total credits. A full-year course counts twice as much as a semester one.
- 3
Add the course bonus
For weighted GPA, Honors courses get +0.5 and AP, IB or dual-enrollment courses get +1.0 before the average is taken. A failing grade gets no bonus.

| Letter | Unweighted | Honors | AP / IB |
|---|---|---|---|
| A+ | 4.0 | 4.5 | 5.0 |
| A | 4.0 | 4.5 | 5.0 |
| A- | 3.7 | 4.2 | 4.7 |
| B+ | 3.3 | 3.8 | 4.3 |
| B | 3.0 | 3.5 | 4.0 |
| B- | 2.7 | 3.2 | 3.7 |
| C+ | 2.3 | 2.8 | 3.3 |
| C | 2.0 | 2.5 | 3.0 |
| C- | 1.7 | 2.2 | 2.7 |
| D+ | 1.3 | 1.8 | 2.3 |
| D | 1.0 | 1.5 | 2.0 |
| D- | 0.7 | 1.2 | 1.7 |
| F | 0.0 | 0.0 | 0.0 |
Next step
Raising your GPA, honestly
- Start with the course that carries the most credits: raising it by one letter moves your GPA the most.
- Find out exactly what you’re losing marks on. Re-read your last two marked tests before you study anything new.
- Short, regular practice beats one long session the night before.
- Ask for help early. An AI tutor that explains a step you missed is quicker than waiting a week for office hours.
Questions
Common questions
What is the difference between weighted and unweighted GPA?
Unweighted GPA puts every course on the same 4.0 scale, so an A is 4.0 whether the class was standard or AP. Weighted GPA adds extra points for harder courses, so an A in an AP class can count as 5.0. Colleges often see both.
How much extra do Honors and AP classes add?
The most common rule is +0.5 for Honors and +1.0 for AP, IB and dual-enrollment courses, and that’s what this calculator uses. Some schools use other amounts or cap weighted GPA, so check your school’s handbook.
Is an A+ worth 4.0 or 4.3?
Most US schools cap an A+ at 4.0, which is what we use. A few count it as 4.3. If yours does, your real GPA will be slightly higher than the one shown.
What counts as a credit?
Usually a full-year course is 1 credit and a semester course is 0.5, but schools vary. If all your courses carry the same weight, leave every credit at 1.
I’m at an IB or British school. Can I use this?
Only if your school gives US letter grades. To see roughly what IB, A-level or IGCSE grades mean in US terms, start with the grade converter.
Is what I type saved anywhere?
No. Everything stays in your browser and is gone when you leave the page.
