GPA Calculator

GPA Calculator — What It Does

Add your courses, select your letter grade for each, and enter the credit hours. The calculator instantly computes your weighted GPA on the standard 4.0 scale, accounting for the credit value of each course. Add or remove courses as needed to plan future semesters or see how a grade change would affect your cumulative GPA.

Standard 4.0 Grade Scale

• A / A+ — 4.0 grade points
• A− — 3.7 grade points
• B+ / B / B− — 3.3 / 3.0 / 2.7 grade points
• C+ / C / C− — 2.3 / 2.0 / 1.7 grade points
• D+ / D / D− — 1.3 / 1.0 / 0.7 grade points
• F — 0.0 grade points

GPA Formula

GPA = Sum of (Grade Points × Credit Hours) / Total Credit Hours

Example: A in a 3-credit course (4.0 × 3 = 12) + B in a 4-credit course (3.0 × 4 = 12) = 24 quality points ÷ 7 total credits = 3.43 GPA.

Tips for GPA Planning

• Front-load effort — Early GPAs are easier to raise; the more credits you earn, the harder it is to move the needle.
• High-credit courses matter most — A 5-credit lab course has more impact than a 1-credit elective.
• Grade replacement — Some schools allow retaking a failed course with the new grade replacing the old one in GPA calculation.

Frequently Asked Questions

How is GPA calculated on a 4.0 scale?

Each letter grade is converted to a grade point (A=4.0, B=3.0, C=2.0, D=1.0, F=0.0). Multiply each course's grade points by its credit hours to get quality points. Sum all quality points and divide by total credit hours. For example, an A in a 3-credit course contributes 12 quality points (4.0 × 3).

What is the difference between GPA and weighted GPA?

Standard (unweighted) GPA treats all courses equally on a 4.0 scale. Weighted GPA awards extra points for honors, AP, or IB courses — typically adding 0.5 for honors and 1.0 for AP/IB, allowing GPAs above 4.0. Colleges usually recalculate GPA using their own unweighted scale when reviewing applications.

Does a W (Withdrawal) affect my GPA?

A W typically does not factor into your GPA calculation — it appears on your transcript but contributes zero quality points and is excluded from credit hour totals. However, multiple withdrawals may raise flags during academic review or financial aid evaluation, even if they do not lower your numeric GPA.

How many credit hours do I need to raise my GPA significantly?

Improving a GPA becomes harder as you complete more credits because each new course is a smaller fraction of the total. With 30 credits earned, a 4.0 semester (15 credits) can move your GPA by about 0.3–0.4 points. With 90 credits, the same semester might only move it 0.1–0.15. Early semesters have a disproportionate impact.

What is a good GPA for graduate school or jobs?

For most graduate programs, a 3.0 is the minimum and 3.5+ is competitive. Top programs in law (for law review), medicine, and PhD programs may look for 3.7+. For employment, GPA matters most in the first job search — typically anything above 3.0–3.5 is considered strong, and many employers stop asking after 2–3 years of experience.
