Mixed full and half credits
The default has four courses totaling 3.5 credits. Their unweighted quality points total 11, so 11 ÷ 3.5 = 3.14.
Homeschool GPA Calculator
Calculate unweighted and weighted GPA from course credits, base grade points, and any course weight you choose to disclose.
What this calculator does
Enter each course's credit value and base grade points on a 0–4 scale. Added weight points are shown separately so the transcript policy remains visible instead of being hidden inside a letter-grade conversion.

Enter your values
Use zero credits to leave a row out. Base grade points must stay on the 0–4 scale; any honors or advanced-course weight is a separate input.

The entered courses total 3.5 credits, with a 3.14 unweighted GPA and 3.43 weighted GPA under the entered weighting policy.
Formula and methodology
For each course, quality points = credits × grade points. Unweighted GPA is total unweighted quality points ÷ total credits.
Weighted quality points use credits × (base grade points + added weight points). Weighted GPA is total weighted quality points ÷ total credits.
The arithmetic does not choose a grading scale. Enter the base points and added weight that match the transcript policy you intend to publish.
Worked examples
Separate course weight
One course adds 0.5 weight points and a half-credit course adds 1 point. Weighted quality points total 12, so 12 ÷ 3.5 = 3.43.
How to use the result
Sensitivity hint: Courses with more credits move the result most. Added weight changes only the weighted GPA, while changing base grade points changes both results.
Common mistakes
- Averaging course grades without accounting for half-credit or multi-credit courses.
- Adding honors weight to the unweighted GPA instead of keeping the two calculations separate.
- Publishing a weighted GPA without explaining the weighting scale on the transcript profile or notes.
What to do next
Keep the course list, grading scale, and weighting explanation with the transcript. Confirm how each college, scholarship program, or school system asks applicants to report GPA.

Limitations: There is no single universal weighting policy. This calculator accepts your entered 0–4 base scale and added weight points; it does not decide course rigor, convert percentages, assign credits, or predict how a recipient will recalculate GPA.
Homeschool GPA Calculator FAQs
Should a homeschool transcript show weighted or unweighted GPA?
Requirements vary. Keeping both calculations available and stating the weighting policy makes the transcript easier to interpret.
How do half-credit courses affect GPA?
A half-credit course contributes half as many quality points as a one-credit course with the same grade points.
What grade points should I enter for an A, B, C, or D?
Use the scale stated on the transcript. A common unweighted scale uses 4, 3, 2, and 1, but plus/minus and other policies differ.
Can a course have zero credits?
In this calculator, zero credits leave that row out of the totals. It is useful for unused rows, not for recording a completed non-credit activity.
