Homeschool GPA calculator
Enter each high school course with its grade and credits, and this works out your student's GPA on the usual 4.0 scale, year by year and for all of high school. If any course is Honors, AP or dual enrollment, it shows the weighted GPA as well.

How a GPA is worked out
Each letter grade is worth points: an A is 4, a B is 3, a C is 2, a D is 1 and an F is 0. Multiply each course's points by its credits, add those up, and divide by the total credits. That is the GPA.
An example
English 9 earns an A for 1 credit, which is 4 points. Algebra 1 earns a B for 1 credit, which is 3 points. Art earns an A for half a credit, which is 2 points. That is 9 points over 2.5 credits, and 9 divided by 2.5 is a 3.6 GPA. On a blank list, "Show me an example" above loads it into the calculator.
How to tell an A+ from an A
Add up every point your student earned in the course and every point they could have earned, then divide. A student who earned 470 of 500 points has 94%, which is an A. Round to the nearest whole percent first, so 92.5% rounds to 93%, an A, and 92.4% rounds to 92%, an A-. Bigger tests count for more this way, because they carry more points. A score you only have as a percent counts as a 100-point score.
The grading scale
This is the ten-point scale: 90 to 100 percent is an A, 80 to 89 a B, 70 to 79 a C, 60 to 69 a D, and below 60 an F. If you use plus and minus grades, these are the usual points for each. Scales vary from school to school and state to state, and in your homeschool you are the one who sets it.
| Grade | Percent | Points |
|---|---|---|
| A+ | 97-100% | 4.0 |
| A | 93-96% | 4.0 |
| A- | 90-92% | 3.7 |
| B+ | 87-89% | 3.3 |
| B | 83-86% | 3.0 |
| B- | 80-82% | 2.7 |
| C+ | 77-79% | 2.3 |
| C | 73-76% | 2.0 |
| C- | 70-72% | 1.7 |
| D+ | 67-69% | 1.3 |
| D | 63-66% | 1.0 |
| D- | 60-62% | 0.7 |
| F | Below 60% | 0.0 |
| Pass | Pass/fail course | Not counted |
Weighted and unweighted GPA
An unweighted GPA treats every course the same. A weighted GPA gives harder courses extra points: here an Honors course adds half a point and an AP or dual enrollment course adds 1 point, so an A in AP Biology counts as a 5. An F earns no extra points. Put the unweighted GPA on the transcript, and add the weighted one only if a course really was Honors or AP level. Many colleges work out their own GPA from your grades either way.
Pass/fail courses and failed courses
A course graded Pass earns its credits but is left out of the GPA, because it has no points. A course graded F counts in the GPA as 0 and earns no credits.
