How to read the result
Use this result as an estimate and compare it with the scale printed by your school.
District policies and college recalculations can change the official number.
Educational orientation only — not an official transcript GPA. Schools and colleges may use different scales and recalculations.
- Compare weighted vs unweighted views when you take advanced courses.
- Colleges may ignore local weights — keep both numbers.
- Use target planner if you have a goal GPA.
Next steps after you finish calculating
• Cross-check with the High School GPA Calculator (unweighted) and Weighted GPA tools.
• Confirm official GPA with your school counselor or portal.
• Use the target or projected planners if you are aiming at a future number.

Limits, assumptions, and what this tool is not
Not your official transcript, not college admissions advice, not a credential evaluation.
District plus/minus rules, repeated-course policies, and dual-enrollment posting differ.

Mini-guide
Mini-guide: compute and sanity-check your GPA
Work from official grades, pick the correct scale (weighted vs unweighted), then verify credits before trusting any browser result.
The method notes below explain what the calculator includes, what it leaves out, and how to verify the result against your school records.
Steps
- Collect letters/percents and credits from the latest report card.
- Choose unweighted vs weighted per your handbook.
- Run the calculator and record quality points + credits.
- Update cumulative GPA after each official term.
- If aiming at a goal, use the target planner with remaining credits.
Checklist
- Credits match the transcript
- Course levels correct (Honors/AP)
- Same scale across compared terms
- Compared against portal GPA when available
| Concept | Rule of thumb |
|---|---|
| Unweighted | Σ(points×credits)/credits on 4.0 |
| Weighted | Add local rigor boosts, then average |
| Cumulative | Blend prior QP with new term QP |
| College view | May drop weights / limit to cores |
Worked examples
Equal-credit semester
A, B, B, and C at 1 credit each produce (4 + 3 + 3 + 2) ÷ 4 = 3.000.
Action: Use this tool separately for any grade year or marking period.
Mixed course credits
An A at 1 credit and a B at 0.5 credit produce (4.0×1 + 3.0×0.5) ÷ 1.5 = 3.667.
Action: Do not count a half-credit course as a full-credit course.
Term result versus cumulative result
A 4.0 semester is not automatically a 4.0 cumulative GPA because earlier quality points remain in the total.
Action: Roll the completed term into the Cumulative GPA Calculator.
Common mistakes
-
Mixing weighted and unweighted points
Keep scales consistent when updating cumulative GPA.
-
Ignoring credits
Half-credit courses should not count as full credits in credit-weighted systems.
-
Assuming colleges use local weights
Many admissions offices recalculate — report both weighted and unweighted when asked.
-
Linear conversion as “official” international GPA
Credential evaluators use course-by-course methods; linear maps are orientation only.
Special situations
- Plus/minus schools: if your legend has no A-, use whole-letter maps only.
- Repeated courses: some districts replace the grade; others average attempts.
- Dual enrollment: may appear on both HS and college records with different rules.
