Formula / how it works
Weighted GPA = Σ(grade_points × credits) / Σ(credits). On a classic unweighted 4.0 scale, A=4.0, A−=3.7, B+=3.3, B=3.0, and so on (confirm your school’s table). Worked check: grades/credits 4.0×3 + 3.7×3 + 3.3×4 + 3.0×2 → quality points 12+11.1+13.2+6 = 42.3; credits 12 → GPA = 42.3/12 = 3.525.

What this calculator is
A GPA calculator turns course grades and credit hours into a single weighted average — the number colleges, scholarships, and employers often glance at first. MyCalcsWorld’s GPA tool expects one course per line as grade,credits (for example 3.7,3 for an A− worth three credits) on a 4.0-style scale. It is built for transparent planning: see how one hard class moves the average, compare “what if I get a B vs an A,” and reconcile with your registrar’s published conversion table. Weighted AP/IB boosts, pass/fail, and repeated-course policies differ by school — match their rules before treating a target as official. Educational estimate only — not a transcript.
When to use / who it helps
- Estimating semester or cumulative GPA before grades post.
- Stress-testing how one course grade changes the average.
- Checking scholarship GPA thresholds against realistic grades.
- Explaining weighted credits to a student or parent.
- Converting a quick planning list into a single 4.0-style number.
How to use
Steps
- Open the GPA Calculator and read the Courses textarea hint.
- Enter one course per line as grade,credits (demo: 4,3 then 3.7,3 …).
- Use your school’s grade-point table (A=4.0, A−=3.7, …) unless told otherwise.
- Read the weighted GPA in the result panel.
- Optional: change one grade to see sensitivity before a final exam.
- If you need percent↔GPA conversion, open the related GPA↔percentage tool.
How to interpret results
- Primary result is credit-weighted GPA on the scale you entered.
- Heavier-credit courses move the average more than light electives.
- A 3.5 planning GPA is not the same as a weighted AP transcript GPA.
- Compare against your syllabus / registrar policy, not a generic chart.
- Educational planning aid only.
Common mistakes & gotchas
- Using percent scores (e.g. 92) when the form expects grade points (e.g. 3.7).
- Forgetting credit hours — unweighted averages mis-rank heavy courses.
- Mixing 4.0 and 10-point scales in the same list.
- Ignoring school rules for repeats, withdrawals, or pass/fail.
- Treating this browser estimate as an official registrar transcript.
Worked example
Worked example — four courses on a 4.0 scale
- Courses: 4.0 (3 cr), 3.7 (3 cr), 3.3 (4 cr), 3.0 (2 cr).
- Quality points = 4×3 + 3.7×3 + 3.3×4 + 3×2 = 12 + 11.1 + 13.2 + 6 = 42.3.
- Credits = 3+3+4+2 = 12.
- GPA = 42.3 / 12 = 3.525.
- Enter the same lines on this page to mirror live rounding.
Result: About 3.53 weighted GPA for those four courses — confirm your school’s grade table.

Frequently asked questions
How do I enter courses?
One course per line as grade,credits — for example 3.7,3. Grade is on the point scale (usually 0–4), not a percent.
Is this weighted or unweighted GPA?
It is credit-weighted. It does not automatically add AP/IB bumps unless you enter the boosted grade points your school uses.
What if my school uses a 10-point or percentage GPA?
Convert to the scale this form expects first, or use a dedicated percentage/GPA converter that matches your board’s policy.
Do withdrawals and pass/fail count?
Policies differ. Many schools exclude pass/fail from GPA; withdrawals may or may not appear. Follow your registrar.
Can I project “what final do I need?”
Use the Final Grade calculator for exam targets; use this GPA tool once you have course-level grade points.
Is this official for applications?
No. It is an educational MyCalcsWorld estimate. Transcripts and counselor reports are authoritative.
What does the GPA Calculator on MyCalcsWorld actually compute?
Weighted GPA from course grades and credit hours (4.0 scale). You enter Courses (grade,credits per line — grade 0–4), and the result panel updates in your browser — free, no signup. Below the form you will find when-to-use tips, common mistakes, a worked example, formula notes, and FAQs for this tool.
How do I use the GPA Calculator step by step?
Start from the defaults (courses (grade,credits per line — grade 0–4) 4,3 3.7,3 3.3,4 3,2) or type your own values into Courses (grade,credits per line — grade 0–4). Watch the live results (and any chart or table). Then scroll to interpretation tips and the worked example before you rely on the figure for a real decision.
