Combined GPA Calculator

About the Combined GPA Calculator

If you've attended multiple institutions, your overall academic performance can't be captured by a single transcript. Graduate schools, employers, and professional licensing boards often want a combined GPA across all institutions. This calculator merges GPAs from up to four schools into one aggregate number.

Enter each institution's GPA and total credit hours. The calculator weight-averages them by credit hours to produce a true combined GPA. A 3.8 from a school where you earned 30 credits and a 3.0 from a school where you earned 60 credits produces a combined 3.27 — not 3.4 (the simple average).

This is especially useful for professional school applications (law, medical, dental) where services like LSAC and AMCAS calculate a combined GPA from all undergraduate institutions attended.

When This Page Helps

Professional school application services (LSAC, AMCAS) calculate a combined GPA from every college you've attended. Knowing this number in advance helps you understand your competitive standing and avoids surprises during the application process.

How to Use the Inputs

1. Enter the name of each school/institution.
2. Enter the GPA earned at each institution.
3. Enter the total credit hours earned at each.
4. Add up to four institutions.
5. Review the credit-weighted combined GPA.
6. Use this for application preparation and planning.

Example Calculation

Tips & Best Practices

• Credit-weighted averaging means the school where you earned more credits has more influence.
• LSAC calculates combined GPA for law school applications from all schools.
• AMCAS does the same for medical school applications.
• Even summer courses at another school are included in combined GPA calculations.
• Dual enrollment (high school + college) courses may be included depending on the application service.
• Community college credits can pull down or raise combined GPA depending on performance.

Why Combined GPA Matters

For single-institution students, combined GPA is irrelevant — it matches their cumulative GPA. But for the millions of students who transfer, take summer courses elsewhere, or do dual enrollment, combined GPA tells the full story. Professional schools need this complete picture to fairly evaluate applicants.

Application Service Calculations

LSAC's combined GPA sometimes differs from what students expect because it recalculates using its own grade conversion table. Pass/Fail courses might be treated differently. Some plus/minus grades are converted to different quality point values. Always verify with the specific service.

Strategic Implications

If you have a low GPA at one institution, earning credits at another with a high GPA will improve your combined number, but it takes many credits to move the needle. The math simply reflects reality: more credits at a higher GPA improves the overall picture, weighted appropriately.

Frequently Asked Questions

• How do I combine GPAs from two schools?

  Multiply each school's GPA by its credit hours, add the products, then divide by total credit hours. Example: (3.5×60 + 3.0×40) / 100 = 330/100 = 3.30. This credit-weighted average accounts for the different amounts of work at each school.

• Is combined GPA a simple average?

  No, it's a credit-weighted average. If you earned 90 credits at one school and 10 at another, the 90-credit school dominates the combined GPA. Simple averaging would give equal weight to both, which is inaccurate.

• Do professional schools really use combined GPA?

  Yes. LSAC (law), AMCAS (medical), AACOMAS (osteopathic), and AADSAS (dental) all calculate a combined GPA from every undergraduate institution attended. They may also calculate separate science and non-science GPAs.

• Does dual enrollment count?

  If you earned college credit through dual enrollment (taking college courses while in high school), those grades typically appear on a college transcript and may be included in combined GPA calculations by application services. Use this calculator to model different scenarios and find the best approach.

• Can I exclude a school from my combined GPA?

  No. Application services require reporting all schools attended. Omitting a school is considered academic fraud. The combined GPA includes everything, good and bad.

• How do summer courses at another school affect combined GPA?

  Summer courses at another institution count as a separate school in your academic history. The grades and credits are included in the combined GPA weighted by credit hours.
