This page explains exactly how gpaestimate.com calculates the numbers it shows you, and what those numbers do and don't tell you.

The calculation

For every course, we multiply its grade-point value by its credit hours to get quality points. We sum quality points across all valid rows and divide by total attempted credits. No rounding happens until the final GPA, credit total, and quality-point total are displayed, each to two decimal places.

Grading scales

The grade-point values behind each scale are configuration data, not hardcoded logic — this is what lets us add more institutional scales over time. The "Standard 4.0" scale reflects the plus/minus convention used by most U.S. colleges. University-specific grading information should always be confirmed against official institutional sources, since schools set their own policies and can change them.

What our numbers are — and aren't

• Results are estimates. Verify anything that matters against your official transcript.
• Standing labels like "Typical Dean's List range" describe common patterns, not your school's actual policy — Dean's List, honors, and probation thresholds vary by institution.
• The GPA Predictor solves a simple algebraic target; it doesn't know your school's specific rules about repeated courses, grade replacement, or rounding.

Your data

Calculator data remains on your device unless you explicitly choose to save a semester, which stores it in your browser's local storage only. Nothing is sent to a server.
