GPA is computed on the standard US 4.0 unweighted scale (A = 4.0, A− = 3.7, B+ = 3.3, and so on). The weighted scale adds +0.5 for Honors classes and +1.0 for AP/IB, following the most common US high school convention. Individual institutions use variants (some count A+ as 4.3, some use a 100-point scale instead); check your school's registrar for the official calculation.
The GPA Calculator computes Grade Point Average on the standard US 4.0 scale. Enter your courses with grades (letter or percentage) and credit hours; the tool calculates semester and cumulative GPA. Supports both unweighted (standard scale) and weighted (AP/Honors courses count more) GPA.
For college: helps track academic standing, plan for graduation, estimate transcript appearance for applications. For high school: important for college admissions, scholarships, honor roll qualification. Handles any number of courses and terms.

Technical details
Standard unweighted GPA scale:
- A = 4.0, A- = 3.7
- B+ = 3.3, B = 3.0, B- = 2.7
- C+ = 2.3, C = 2.0, C- = 1.7
- D+ = 1.3, D = 1.0, D- = 0.7
- F = 0.0
GPA formula: sum(grade × credits) / sum(credits)
Example: Biology (A, 4 credits) + Math (B+, 3 credits) + English (B, 3 credits):
GPA = (4.0×4 + 3.3×3 + 3.0×3) / (4+3+3) = 34.9 / 10 = 3.49
Weighted GPA: AP and Honors courses get bonus points:
- AP: +1.0 to grade (A = 5.0)
- Honors: +0.5 to grade (A = 4.5)
Some schools use 5.0 maximum for weighted; others cap at 4.5.
Percentage-to-GPA conversion (varies by school):
- 93-100 = A = 4.0
- 90-92 = A- = 3.7
- 87-89 = B+ = 3.3
- 83-86 = B = 3.0
- 80-82 = B- = 2.7
- 77-79 = C+ = 2.3
- 73-76 = C = 2.0
- 70-72 = C- = 1.7
- 67-69 = D+ = 1.3
- 63-66 = D = 1.0
- 60-62 = D- = 0.7
- 0-59 = F = 0.0
Cumulative GPA: average of all semesters, credit-weighted (not simple average of GPAs). Each semester\u2019s grades contribute proportionally to total credits.
Honor rolls:
- Dean\u2019s List: typically 3.5+
- Honor Roll: varies by school
- High Honors: typically 3.8+
- Summa Cum Laude: 3.9+
- Magna Cum Laude: 3.7-3.89
- Cum Laude: 3.5-3.69
College admissions typical:
- Elite schools: 3.9+ unweighted (or 4.5+ weighted)
- Competitive: 3.7-3.9
- Average: 3.5+
- Community college: lower thresholds
Calculation precision: GPA typically reported to 2 decimals. Higher precision rarely matters; transcripts show 2-3 decimals.
Retakes and replacements: many schools let you retake courses; policies on whether new grade replaces old vary. Calculator assumes no replacement; manually adjust.
Common problems and solutions
⚠Different school scales
Not all schools use 4.0 scale. Some use 5.0 (weighted), 100-point, A-F alpha only. Check your school’s system.
⚠Weighted vs unweighted different
Colleges ask for different versions. Some convert all to unweighted themselves; others want weighted as your school reports.
⚠Percentage-to-letter varies
School grade scales differ. 93-100=A here but 90-100=A elsewhere. Use your school’s exact scale for accuracy.
⚠Credits vary
Credit hour values differ by course. Lab science often 4; lectures typically 3. Use actual credits from your registration.
⚠Passing grades
What counts as passing (for graduation credit) varies: usually C- or better. GPA calculation still uses actual grade even if you pass.
⚠Pass/Fail courses
P (pass) usually doesn’t affect GPA. F (fail) in pass/fail sometimes counts as 0.0. Treatment varies; check school policy.
⚠Retake replacement
If retaken course replaces old grade, use new; if both count, include both. Different schools have different rules.

Frequently asked questions about the GPA Calculator
▶What is GPA?
Grade Point Average, a numerical representation of academic performance. US standard scale: 0.0 to 4.0, where 4.0 is A. Computed as credit-weighted average of grade points.
▶How is GPA calculated?
Multiply each course’s grade points by credits, sum those products, divide by total credits. For 4 credit A + 3 credit B+: (4×4.0 + 3×3.3) / 7 = 3.70 GPA.
▶What’s a good GPA?
Depends on context. 3.5+ generally strong. 3.7+ honor roll territory. Elite college admissions expect 3.9+ unweighted. Community college: 3.0+ acceptable for transfer.
▶What is weighted GPA?
GPA where AP/Honors courses count more. Typically +1.0 for AP, +0.5 for Honors. An A in AP class counts as 5.0 instead of 4.0. Designed to reward taking harder classes.
▶Does every school use 4.0 scale?
No. 4.0 standard in US. Some use 5.0 weighted. Internationally: 10-point scale (India), 20-point (France), percentage (China). Different systems not directly comparable.
▶How do I raise my GPA?
Future course grades affect cumulative GPA weighted by credits. Early years have more time to influence; later years harder to move. Higher grades in higher-credit courses help most.
▶Is my data private?
Yes. All calculation in your browser.
▶What GPA is needed for graduation?
Typically 2.0 minimum, though individual majors or schools may require higher (sometimes 2.5 or 3.0). Check your school’s specific requirements.
