What Getting A B-Minus Means (80% = B-)
Getting a B-minus means finishing the course with 80%. On a standard 4.0 GPA scale, this counts as 2.7 grade points per credit hour. It matters for: financial aid GPA minimums and satisfactory academic progress.
A b- may not satisfy financial aid sap requirements - check your aid gpa threshold. Use the calculator above for your exact numbers, or use the table below for a quick reference across the most common final weights and current grades.
Formula: Required Final Score = (Target 80% - Current Grade × Current Weight%) ÷ Final Weight%
Example: Current 80%, final worth 30%, target 80% → Required = 80.0%
Example: Current 80%, final worth 30%, target 80% → Required = 80.0%

How to Interpret Your Result
- "Done" - You have already locked in a B-minus. Even a zero on the final will not drop you below 80%. You can adjust your study priorities.
- Under 70% - Very achievable. A solid preparation effort should get you there.
- 70-85% - Solid prep required. Dedicate real time to this final.
- 85-95% - You will need a strong performance. Start early and use practice exams.
- 95-100% - Possible but you will need close to a perfect final. Review everything systematically.
- ">100%" - Mathematically out of reach. Lower your target and recalculate, or speak with your professor about options.
