How Cumulative GPA Is Recalculated
Adding a new semester to your cumulative GPA means combining your existing grade points with new grade points earned, weighted by credit hours for each.
How to Calculate Your Updated Cumulative GPA
New Cumulative GPA = (Current GPA × Current Credits + New Grade Points) ÷ (Current Credits + New Credits).
GPA Calculator Formula
- Total Grade Points = (Current GPA × Current Credits) + New Semester Grade Points
- Total Credits = Current Credits + New Semester Credits
- New Cumulative GPA = Total Grade Points ÷ Total Credits
Why Can't I Just Average My Semester GPAs?
Because a simple average of semester GPAs ignores credit-hour weighting — a semester with more credit hours should count proportionally more toward your cumulative GPA than a semester with fewer credits, which a straight average doesn't reflect correctly.
GPA Update Examples
3.5 GPA on 45 credits, new semester earns 54 grade points on 15 credits: New GPA = (3.5×45 + 54) ÷ (45+15) = 211.5 ÷ 60 ≈ 3.52.
Common GPA Recalculation Mistakes
Averaging semester GPAs directly instead of weighting by credit hours. Including Pass/Fail or Incomplete grades in the grade-point calculation when your institution's policy excludes them. Using a different grading scale than your school actually uses — verify your school's exact letter-grade-to-point conversion before relying on any calculator's default scale.
How to Use This Calculator
Enter your current cumulative GPA and total credit hours completed so far, then your new semester's total grade points earned (sum of each course's grade value × its credit hours) and new credit hours.
Formula & Methodology
New Cumulative GPA = (Current GPA × Current Credits + New Grade Points) / (Current Credits + New Credits) — a credit-weighted average of your prior and new coursework.
Example: 3.4 GPA on 60 credits, plus 15 new credits worth 54 grade points
(3.4 × 60 + 54) / (60 + 15) = 258 / 75 = 3.44.
This is a general credit-weighted cumulative GPA calculator on a standard 4.0 scale — it is not the official LSAC GPA recalculation, which reprocesses each individual course grade using LSAC's specific conversion scale. For law school applications, use LSAC's official CAS GPA report as the authoritative number.
For general reference only. Law school and other program admissions decisions rely on official GPA calculations from your registrar or LSAC — use this as an estimate, not an official record.

Frequently Asked Questions
- How do you calculate cumulative GPA?
- Multiply your current GPA by your current credit hours to get total grade points, add your new semester's grade points, then divide by your total combined credit hours.
- Is this the same as my official LSAC GPA?
- No — LSAC recalculates every individual course grade using its own specific scale for law school applications. This calculator gives a general estimate using your school's standard 4.0-scale GPA.
- What are 'grade points' for a semester?
- It's the sum of each course's grade value (e.g., A=4.0) multiplied by its credit hours, added up across all courses that semester.
