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.

Calculate credit-weighted GPA

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.

Default worked example

Weighted GPA 3.43
Unweighted GPA 3.14
Total credits 3.5
Weighted quality points 12
Unweighted quality points 11
Courses counted 4

The entered courses total 3.5 credits, with a 3.14 unweighted GPA and 3.43 weighted GPA under the entered weighting policy.

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.

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.

How to use the calculator

Enter up to four courses under an explicitly entered 0–4 base grade and added-weight policy. Credits run from 0 to 10 in 0.25 increments; base grade points run from 0 to 4 in 0.01 increments. Added weight runs from 0 to 2 in 0.25 increments. At least one course must have positive credit.

What the result means

Two one-credit courses with grade points 2.01 and 3.02 have 5.03 quality points over 2 credits: GPA is exactly 2.515 and displays as 2.52. Weighted GPA can exceed 4 because added weight is explicitly entered. The displayed quality-point totals and GPAs round independently.

Formula and units

Unweighted quality points = sum(credit × base grade). Weighted quality points = sum(credit × (base grade + entered added weight)). Divide each quality-point total by the total positive credits. Zero-credit rows contribute no quality points and are not counted. Exact entered increments are retained until the final half-up display rounding.

Worked examples

Credits: 1 credits; Base grade points (0–4): 4 grade points: Credits: 1 credits; Base grade points (0–4): 4 grade points; Added weight points: 0 added grade points; Credits: 1 credits; Base grade points (0–4): 3 grade points; Added weight points: 0.5 added grade points; Credits: 0.5 credits; Base grade points (0–4): 4 grade points; Added weight points: 1 added grade points; Credits: 1 credits; Base grade points (0–4): 2 grade points; Added weight points: 0 added grade points.
Example result: Weighted GPA: 3.43; Unweighted GPA: 3.14; Total credits: 3.5; Weighted quality points: 12; Unweighted quality points: 11; Courses counted: 4.

Credits: 1.5 credits; Base grade points (0–4): 4 grade points: Credits: 1.5 credits; Base grade points (0–4): 4 grade points; Added weight points: 0 added grade points; Credits: 1 credits; Base grade points (0–4): 3 grade points; Added weight points: 0.5 added grade points; Credits: 0.5 credits; Base grade points (0–4): 4 grade points; Added weight points: 1 added grade points; Credits: 1 credits; Base grade points (0–4): 2 grade points; Added weight points: 0 added grade points.
Example result: Weighted GPA: 3.5; Unweighted GPA: 3.25; Total credits: 4; Weighted quality points: 14; Unweighted quality points: 13; Courses counted: 4.

Limitations and common mistakes

This is a credit-weighted arithmetic model, rather than a universal transcript policy. Schools and transcript recipients may use different grade conversions, eligible courses, weighting, caps and rounding. This calculator does not convert letter grades, infer semester credits or certify a transcript.

Do not divide quality points by the number of courses when credits differ. Do not add weight to the unweighted GPA or count zero-credit rows. Keep the exact credit and grading policy with a transcript; a recipient may recalculate it.

Sources and assumptions

The weighted-average arithmetic is mathematical; schools and transcript recipients may use different policies.
