How to Calculate GPA

GPA is calculated by dividing total quality points by total credit hours.

Formula: GPA = Total Quality Points / Total Credit Hours

Where Quality Points = Grade Value × Credit Hours for each course.

Step-by-Step Example

  1. English (A, 3 credits): 4.0 × 3 = 12.0 quality points
  2. Math (B+, 4 credits): 3.3 × 4 = 13.2 quality points
  3. History (A-, 3 credits): 3.7 × 3 = 11.1 quality points
  4. Total: 36.3 quality points / 10 credits = 3.63 GPA

Grade Point Scale

The standard 4.0 scale maps letter grades to numbers:

  • A/A+: 4.0 (Excellent)
  • A-: 3.7
  • B+: 3.3
  • B: 3.0 (Good)
  • B-: 2.7
  • C+: 2.3
  • C: 2.0 (Average)
  • D: 1.0 (Below Average)
  • F: 0.0 (Failing)

Cumulative GPA

To calculate a cumulative GPA across multiple semesters, enter your existing GPA and credit hours in the provided fields. The calculator combines your previous academic record with the new courses you add.

How to Raise Your GPA

  • Focus on high-credit courses — an A in a 4-credit course impacts GPA more than in a 1-credit course
  • Retake courses where your school allows grade replacement
  • Take summer courses to add more A-level credits
  • Use the calculator to model "what if" scenarios for target grades

Target GPAs for Graduate School

  • Medical school: Average matriculant GPA is 3.75 overall, 3.68 science. Below 3.5 is a significant disadvantage
  • Law school (top 20): Median GPA around 3.86. Top 10 schools rarely accept below 3.6
  • MBA programs: Top programs average 3.5-3.7. Work experience often matters more
  • PhD programs: Typically 3.3+ for admission, 3.5+ for competitive programs

Weighted vs Unweighted GPA

An unweighted GPA uses the standard 4.0 scale for all courses. A weighted GPA adds bonus points for advanced courses — typically +0.5 for Honors and +1.0 for AP/IB classes — so a weighted GPA can exceed 4.0.

Colleges understand both systems and most recalculate GPAs for fairness. This calculator uses the standard unweighted 4.0 scale.

Dean's List and Latin Honors

  • Dean's List: Typically requires 3.5-3.7 GPA per semester with full-time enrollment
  • Cum Laude: Usually 3.5+ cumulative GPA
  • Magna Cum Laude: Usually 3.7+ cumulative GPA
  • Summa Cum Laude: Usually 3.9+ cumulative GPA

Requirements vary by institution. Check your school's specific thresholds.

Frequently Asked Questions

How do I calculate my GPA?

Multiply each grade point by the credit hours of the course to get quality points, add them up, and divide by total credit hours. An A (4.0) in a 3-credit course and a B (3.0) in a 4-credit course give 12 + 12 = 24 quality points over 7 credits, a GPA of about 3.43.

What is an A- on a 4.0 scale?

An A- is 3.7 on the standard 4.0 scale. The full scale is A+ and 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 and F = 0.0. Some schools score an A+ as 4.3.

What is the difference between weighted and unweighted GPA?

An unweighted GPA uses the standard 4.0 scale for every course. A weighted GPA adds extra points for AP or honors classes, so an A in an AP course can count as 5.0 instead of 4.0. Colleges often recalculate applicant GPAs on their own scale, so both numbers are worth knowing.

How much does one F lower your GPA?

One F in a 3-credit course drops a 3.5 GPA over 30 credit hours to about 3.18, because 105 quality points are now spread over 33 credits. The fewer credits already earned, the bigger the drop. Many schools let a retaken course replace the failing grade, which restores most of the lost ground.
